Some of them have been, or at least one has

sorry I missed most of todays events, just got back from docs

Fed why not join mate, but most of them are victorian so you gotta give them some leeway in the brain department.
Jumpy did you see your mate with the leaking tank got himself banned
That mod 1 bloke don't muck about.

I'm wondering if he's got the fibre washers under the screw heads, it sure doesn't look like it.
Notice there's no goop around the screw heads either, do they think that threads seal fuel I wonder.
F**Ked if I'd be walking around on top of a fuel tank with a connected sender to boot,... arrr that's right... he's got CARPET! HaHaHaHa!

I won't join Frank they're too stupid for me to bother with and I'm not a fan of post deletion and banning.

Yes mate pretty poor way to have a tank set up, but it's OK cause haines said it ism and wait for it, he has a eski that covers the sender and loose wires, so what could possibly go wrong.

You would soon change your mind on that subject if you had to sit through all their dribble.

Now some guy has suggested sanding one side of the hull.

Please make it stop!!!!

Hey what about the drain plug guy?
Someone should tell him to undo the old fitting & put a new one on.

That guy was an utter goose frank

Mod1 did shoot me a friendly pm & i explained to him i refuse to let people get me angry & revert to taking the piss out of them to stay calm/level headed i'd rather be laughing than sulking

What gets me is all the worms who come out of the wood work when they think they've got me

That red guy is an utter twit the only time you'll ever see him rear his head is to have a go @ someone.

Dont worry if you follow the other threads you get a good idea most of the other guys dont get involved sit back & have a laugh @ what i post

That's freckles i have alot of fun with him

That was actually a goodarus thread i'm just sitting back curious whether BC actually did solve the prob

But cant believe how some are still there posting about trim tab anode
Maybe you should register Fed & explain to them the difference between lean & turn ???

They wont risten to me

Had me worried, My haines is a newer model, but my tank is nothing like that, the sender is on the back of the tank.

Spud that boat has had it's floor up no Q about that nor is that a factory fitted sender
Some of those guys are bigger gooses than ewe no hu

Jumpy I will tell you something about that red guy but it would have to be done in PM, if you want to hear it.

Good guess he's got 2 user names

Comes out as red when he wants to bitch

No only the one user name, you're probably not interested but i will tell you anyway.

Tell me! hahaha

Tell me too! HaHaHa

Never seen one mounted on the side rumpus I think it's about time you did a thread on the boat with plenty of pics.

This quote was a classic

Leaves the gumballs quote for dead guess who said it & what it's refering to

I want Rocket Jumpers for the boat

Here we go again, picture showed a trim tab turned to the right.


It only goes to prove that these posters HAVE NEVER DONE IT THEMSELVES.

Who wants the rocket jumpers, you must be getting under someone's skin.

They've got no idea @ all Fed

Then they want to have a go @ me for trying to set the record straight

It's all they know trim tab anode 90% of them wouldn't have a clue on how to drive/trim out a motor/'s to settle a boat so it's driving true

Not all boats are built with same degree angle on transom where motor gets bolted to hell i even had to go 8 degree wedges on mini me to get it runing trurer.

Since gone with last mods

Nothing wrong with adjusting the anode but you'd think they would know which direction to adjust it.
They all seem to think the anode is a rudder for some reason.

I think they're all losing touch because of the NFB & higher ratio hydraulic steering.

Finally some sanity, let's see how many of the wankers eat some humble pie now.

As far as i have understood the trim tab is only to counteract the turn of the prob which trys to turn the motor one way making the steering turn one way easier and the other harder. Its equalizes this by putting a small amount of turn on the motor to make the steering balanced.

The prop has nothing to do with it Rumpus, it's the engine block trying to turn in the opposite direction to the crankshaft.

Go & give your car a small rev while it's in gear with your foot on the brake and watch the engine block try & turn in the engine bay, same thing.

If I give my outboard a rev on the flusher my motor immediately flicks to the right and the prop is not even in the water.

Another point to ponder, twins running one counter rotating gearbox & prop.
They do not cancel each other out because the engines are not counter rotating so they will both still try to turn to the right.

Now if one of the actual engines was a counter rotator then they would cancel each other out completely.

And then there's trim which is a whole new ball game when you consider the attack angle of the prop blades in a negative trimmed or positive trimmed situation.
The moment the prop shaft is not running parallel to the water surface a steering pressure is exerted by the unbalanced blade attack angle from port to starboard.
All of this gets back to people using their trim to counteract a forward/aft weight distribution problem, I see it all the time.

I think a lot of these guys posting have never had cable steering so the NFB hydraulic c/w higher steering ratios is masking what their boats are actually doing.

They should run their boats with a temporary tiller steer to get it set up then connect their hydraulic steering feeling confident if they ever blow a hydraulic hose the boat won't do an instant U turn and chuck them in the water.

Disagree Fed.... Often Counter rotators will have straight tabs as they dont need them, a car engine jumps because of the weight of the flywheel spinning.. Thats why cars have flywheels to provide that turn. If the case was that the motor was trying to turn the boat then it would have not as great effect on the lean as the prop turning would as the prop is trying to spin the boat sideways, just like a drill spears off if you dont have a pilot hole..

"Torque trim tabs help to counteract the effects of torque, or wheel-walk, on the vector of the boat. Wheel-walk is a phenomenon that is created by differing water pressure at the top and the bottom of the propeller. As the propeller rotates through the water, the pressure at the bottom of the propeller is greater than the pressure at the top. This creates greater drag at the bottom than at the top and makes the propeller try to "walk" sideways through the water.

This makes a right-handed prop (clockwise rotation) move laterally through the water, and makes the stern of the boat swing to the right, making the boat turn to the left when underway. Counter-steering with the helm will not correct this and will only succeed in making the entire boat move at an oblique angle to the direction that the bow is pointing."

ust thought, another example of this is when docking a boat... Coming into a wharf at a diagonal and then hiting reverse will bring the stern of the boat into the wharf if you come in the right way, if you come in the wrong way it will move the stern away from the wharf.. In a Clockwise rotating prop you want to approach a wharf with the starb. side closer and then when you hit reverse the boat should skew into position.

Then we'll have to agree to disagree Rumpus.


Just because people don't know how it works doesn't make it right unless you're talking about counter rotating engines and then I agree they will cancel each other out.


The block of a car engine will try and spin in the reverse direction to the crankshaft.
Same as an outboard motor will try & spin in the reverse direction to the crankshaft, OMC even have a built in bias in the trim tab so that when you set it straight it's already got it's trailing edge pointed towards the starboard side.


I have no idea what you are trying to say there mate so I'll put that down as jibberjabber for now.


This is an interesting point you've brought up Rumpus and I think most people are aware that if you're pulling up at a wharf (say 45 degrees on starboard side) and hit reverse with a clockwise prop the boat will skew sideways but tell me this, with higher water pressure on the bottom of the prop & the prop going in reverse why doesn't it skew the back of the boat to the port?


Same as my answer above but reverse the observation to allow for the boat being underway.
I don't dispute the paddle wheel effect at all but you'd think a clockwise rotating prop would walk to the right while underway. I personally believe that effect is so small it's hardly worth mentioning in the context of the discussion.

I'm sticking with the function of the trim tab to counteract the engine torque, the beauty of doing it this way is that the correction is done with water pressure on the tab and being an external force none of this load is transmitted into the hull through the steering and that it's self regulating, as the HP increases so does the speed & so does the pressure on the trim tab.


How do you explain that when the higher water pressure is at the bottom of the prop, the prop is spinning anti clockwise therefore the back of the boat should move to the port.

Interesting shit eh?

Damn, do you have to write so much, its hard to reply to it all...



Most trim tabs have this bias (i assume you mean a concave in the tab) for counters the concave faces the opposite way, if you have twin counters you can get straight ones with no bias. with twins you have much more control over the whole boat also.



Was refering more to a boat at speed in this post.




The engine is balanced, its only the initial burst of torque that turns the engine, then it will balance and sit in its operating position, so by what your saying here is that the boat will only require a trim tab when you are increaseing the revs of the motor, not at a fixed rpm which is incorrect, the probelm exists at fixed speeds and therefore must come down to prop torque not engine torque??

EDIT; Im still thinking bout this but biit sunburnt and sore so will have to get back to this....

Hold your foot on the brake in an auto car and increase the revs, you will see the block turn in the bay and stay there until you take your foot off the throttle.

Boats are always going uphill so the engine is always trying to turn in the opposite direction to the crankshaft.

Mercs don't have a built in bias, does your Yammy have one?

Wizzed through the goose V potato battle

Spud the point you're missing is the guys going on & on & more on about the anode is every one of them has got NR steering

Did battle with that Nolem chappy a while back & now he's echo'n what i told him

Prob with most of these guys is they fail to read what original poster has written & go off 1/2 cocked intheir own world

Yea, im not reading through all that shit, im just going on what was said on here about why the boat has the trim tab (engine tab not boat tabs)

I still beleive that under way the prop turque has more effect on the motor than the engine torque in trying to steer or tilt the boat..

but im sore and tired and cant think clearly so ill have to come back to it..

Ok, another quick one FED...

In a counter setup, the engine still turn the same way, just the gearbox is reversed, so the props spin opposite, therefore the boat becomes balanced? Wouldnt this point to the prob having more to do with the trimming??

Do you recall pez telling me to trim my starboard motor down

To which i replied

Shut the F Up tis my boat & that's where she needs to be ???

Today different load on board different conditions it was a different trim on motors

Prob with alot of peeps is they just dont know how to drive a boat & they get up on threads & give advice to others

Yea but one or both of your motors are cavitating half of the time they are underway!

Guuess your eyesight cant hear it form up the front?

;)

Not what my taco's were saying

Oh Jumpus!! They were trying to tell you but you wouldn't stop talking for long enough for them to get a word in...

Besides, anyone with years of expertise would know, digital instruments are only an indication... a good skipper would listen and feel how the boat was behaving..


Hey While on the topic of instruments.. Any idea's why my Navman 6500 is not giving a temperature reading, havnt been able to find anything in manual or online. Sits on 0.0dC..

Cause it's a toy people put on their 1/2 boats no ther possible reason
So navman dont bother installing sensor probe in the tranny

Your probably right, only people with big green plate boats install probes into tranny's!?

Hehehehehe... Nice work Rummy... Just spat my coffee...

I was thinking Rumpus and that's always dangerous.

Do you think the paddlewheel effect could be a shaft drive thing because I've got to say I've never really noticed it with an outboard but it was very pronounced in the old Gudma which was shaft drive. Because of the angle of the shaft & prop it would change the blade angle from top to bottom and all make sense then.
I don't believe the top to bottom difference in water pressure mate it would be SFA.
I used to rely on it heavily to park the old shaft drive Gudma at the wharf.

Getting back to the Mexican goose I think if he turned the trailing edge of their trim tab harder to starboard & got a decent prop his leaning would disappear.
Edit: Trimming out would help him too.
Another interesting point, Jumpy runs all his trim tabs straight but I guess that doesn't mean much because..... you know.

I know!

Ewe & Shinny head know jack shite

All trip down to spuds it was jumpy whats this for whats that for on my brand new 1/2 boat

Ewe had to settle for a 1/2 boat cause jumpy wouldn't sell you mini me a full boat

I think they got you Lady JAJAGEE, my tank looks exactly the same, only the sender is mounted on the back face of the tank, behind where the filler/pickup/breather are.

Did they ???

Keep watching the thread & watch the master unleashed

im waiting! ;)

Think they're hiding from me spud

Want a few more to to say what tanks were made off

prob with most of those guys is they dont observe, read or have capacity to think, just jump on lets get jg bandwagon

what is your point though? You said that the setup was not factory and it appears that it is factory no??
