Yamaha Rebuild Options

[Jumpus GooDarus]

I know that poly chappy is interested in the annode setup on my Yams, will take pics of old wuns once we start putting motors back together

Did go pic up my Power Heads Today all wrapped up sqeaky clean even wrapped in plastic they rival Fed's

Gearbox's & Cowls are going into paint shop tommorro, cowls would've been A OK exept that I'd 4gotten to close the transom door on the boat wun day & tilted the motors up, port cowl copped a wittle hole in it when it head butted the door.

Repair was easy, saves me doing it a mate is going to repray them for me

Jumpy. I have missed something here, why are you re building your motors ?.
Could you lead me to a link where you are explaining what went wrong.

Motors were fine Frank

But sumthing has been annoying me on the port motor for last 12 months or so

Rev the motor out to say 5500 rpm & it goes fine for around 5 minutes then dies in the arse but never stalls, originally thought it was computor related cause once ewe turned that motor off & rebooted the computor it ran right for another 5 minutes then died in the arse again.

Took boat in twice & ran motors through the Yamaha analasis prog & it showed nothing was amiss, but like most things prob only occured when motor was under load.

Wun day I figured out wot the prob was, after the motor was giving me the shits I flicked the fuel line cocks over & ran that motor on the rear tank & prob went away.

I knew now wot the prob was & only got around to lifting the foor up to clear the blockage a couple of weeks back & boy was it blocked not in the tank but in the s/s fuel line had to poke some heavy wire in there to release the swarf..

Guess there's a bit more sum where & my guess is in the fuel reservoir on the motor itself, haven't gotten around to pulling anything apart yet cause I wanted to be involved in the rebuild of motors.

I've owned the motors 4 years now & they were 12 months old when I got them we didn't know how much work they'd done previously so decided to pull the heads off & have a looky.

All's good cylinder/piston etc wise, may have cost me a few $$'s pulling the heads off but @ least now I wont have to touch anything again for yonks

poly here's those anodes ewe asked about, as ewe can see my wuns are doing their job they were replaced 12 months ago
The wuns on the right came out of a 225 hp yammy today

in the smaller HP motors the anodes may not be in the heads but screwed into the block itself

[poly]

thanks for the photo J.G.,I will have to find out were they are on my little 40hp

[Fed]

Are you saying that the anodes pictured are only 12 Months old, if so I'd be asking a few questions like, "WHY".

[Jumpus GooDarus]

Wot ewe on about Fed ????

[Seafairy]

JUMPUS ...G'day!

your post was a little confusing:

We were wondering if the pic you showed were the anodes - on the left, you took off 12 months ago (which meant they had got into that state in 3 years)
OR
the ones you have just taken off?

Nothing Confuciosaring abot wot I said @ all even labeled the pic with wittle writtings

Both sets of anodes were in 2 different motors for 12 months

Left wuns still bolted onto their brackets are off my yams & they're nearly worn down to nothing 9that's wot they're supposed to do] cause when heads came off all galleries etc in the block were clean as a whistle not bad for 6 yo motors

Wuns on right are also 12 months old they came out of a later model 225 hp yam, & not eroded away much @ all esp considering motor sits on an LFB boat which gets used all the time

[Fed]

When I first saw your skegs I said you had a problem. now that I've seen your anodes I'll say it again, "You have a problem".
Sure they're working, working overtime.... why?
The 225HP ones look as I would expect after 12 Months.
Your boat hasn't had a lot of use over the last 12 Months either.

[Jumpus GooDarus]

Getting the feeling it's gonna be wun of those fed days



Wot dont ewe get Fed surely ewe cant be thick as a ????

When I first saw your skegs I said you had a problem.

I dont pay attention to anything ewe say

Wots wrong with my skegs ??????

Woopy so they're missing paint down the bottom

I'll let ewe in on a wittle secret Fed

No matter how well ewe prep existing alloy which is not new paint will eventually peel away

Alloy is very porous & will hold contaminants

But just to make ewe happy I'll check to make sure my breathers aren't blocked

[poly]

I have a question, an important one I would think.

IS it necessary it strip the heads off to change the anodes??????????????????????

JUMPY .... JUMPY ... JUMPY!

No poly !

Have a look @ the pic & ewe'll see holes on end of bracket
2 bolts secure bracket onto motor

Now down the guts ewe'll see another bolt, this bolt secures the anode to the bracket

If ewe ever want to check on the condition of your anodes just undo the 2 outer bolts tis that simple then screw them back in no gaskets etc needed

[Jumpus GooDarus]

JUMPY .... JUMPY ... JUMPY!

Like talking to a brick wall @ times seafairy

He picks on the most trivial things without understanding wot causes them

I even in person told him why the skegs had lost the paint & still he regards this as a prob

Dont think to many go to the trouble maintaining their boats the way I do, & if I think their is a prob I dont hesitate to sort it out

[Fed]

Your anodes and skegs are dissolving faster than Aspros in boiling water and you say, "Look how good they're working".
You are looking at it through rose coloured glasses mate.

The lack of paint on the skegs is nothing, what I commented on was the alloy looked like fresh galvanised plating.

12 Months use say 50 hours max, your anodes should look brand new, they're almost gone!

You should be asking yourself... WHY ARE MY ANODES DISSOLVING SO QUICKLY? ... could there be a problem?

Dont care Fed !

Cause they're doing the job they are supposed to be doing, look anywhere else on my motors & ewe wont find any alloy corrosion not even internally esp the water galleries where ewe would expect to find corrosion.

My donks are 6 years old now & they're in better appearance wise nick than that 225 hp which is only 2 years & has visible corrosion externally

Obviously his anodes aren't doing their job as good as mine

Also remember my goat is alloy construction unlike the 225hp which is a Glass goat

[Fed]

Dont care Fed !

That's all you had to say.

Wun day I figured out wot the prob was, after the motor was giving me the shits I flicked the fuel line cocks over & ran that motor on the rear tank & prob went away.

I knew now wot the prob was & only got around to lifting the foor up to clear the blockage a couple of weeks back & boy was it blocked not in the tank but in the s/s fuel line had to poke some heavy wire in there to release the swarf..

Guess there's a bit more sum where & my guess is in the fuel reservoir on the motor itself, haven't gotten around to pulling anything apart yet cause I wanted to be involved in the rebuild of motors.

Why would the problem be in the motor if the problem went away when you swapped tanks?
I do read what you write mate.
