Boris. ring the guy who's number is on the cowling and ask him does he have any records as to what work he has done on the motor.
You may have to pay him a search fee but he may be able to tell you a few things about the engine.

yes Frank, i did that yesterday, and i'm scheduled to see him on saturday.
if anythings wrong with it I'll return the boat anyway.

how do i do that?

Mate I used to own a pair of those Enenrudes in a bigger HP many years ago if it was a Yammy I'd be able to tell you right away where the cover to the thermostat was but it's been to long since I've looked @ a Evinrude.

Anyway shop be fairly simple to find & prob only 2 maybe 3 bolts holding the cover on look up high on the motor for it, being a V 4 good guess is @ rear of motor

Boris,

Are you using dolphin ears or is the lower leg in a drum of water?

If dolphin ears you have the water turned up? Hate to think you were starving it of water.
Try turning the tap on full pressure. This will help eliminate the thermostat if you have a worn/cracked/deformed impellor.

I do agree with Poly, changing the impellor would give you peace of mind but just checking it carefully also would help. You just do not know the history of the impellor, somebody could have started and ran the engine dry. I assume you know how to check an impellor, if not I am sure you will ask.

i was using the rabbit ears, not the dolphin ones... hehehe... joking...
well, there was plenty of water pressure in neutral... and when i put it on the gear the water starts to play around...

tonight i'll have a look at the thermostat...

[poly]

mate can u put up some photos of the motor with the cowl off, the thing i am worried about is the boat looks very neglected, nothing that can't be put wright of course, its just that when one part is neglected u can bet the rest is as well, just how extensive was the rebuild, do u know????????????????

That is strange.

So the motor would have good water pressure for say 5 minutes of idling and a 2000rpm short rev. (Or is it only idling??)
Then you put it into gear and say rev it to 1500 and the water pressure pluses. (Or is it only idling??)

If only idling what happens it you increase the revs a little?
My guess is a water impellor more than the thermostat, but need more info.

Didn't you say you bought it from a mechanic?
Is he known to you, your mechanic?
Good place to start asking WHY is this happening tomorrow as you have said?

yeah i did say that i bought it from my mechanic, but he is my car mechanic not the outboard mechanic hehe...
and the guy who built the engine is my outboard mechanic. My car mechanic and i are using the same outboard mechanic. I know the both mechanics very well.
The engine is rebuilt in 2007. its a 1986 model.

mate can u put up some photos of the motor with the cowl off

Polly, inside of the outboard looks like its brand new, I'll take some pic tomorrow morning.

I'll go to the outboard mechanic tomorrow morning, i spoke to him today he said should be the impeller.
As you guys said i'd change the impeller anyway. I think i'll have some time tomorrow and change the impeller.

The boat is not that bad as seen in the pic. It just need some tidying. but it is really really dirty.

i think they all look the same as its had a cover over it for its whole life

I hate spelling.

It's impeller

Back to school for me <:-(

[quintrex101]

howed you go boris ????

[boris]

howed you go boris ????

by car

[boris]

just came from the mechanic.

Impeller needs to be changed but he was su busy so i'll change it. other than that its all good.
It had a rebuilt early last year. So impeller is due to change anyway.

If i can change the impeller by then, i'll put it on the water on monday.

I'll put some more photos

[boris]

here you go polly

I say BS. :2guns: What the boat has hardly been used since the rebuild and it needs to be changed.
My guess
1) Impeller was not changed when rebuilt 12 months ago
2) If definitely replace 12 months ago somebody ran the motor dry
3) Cheap impeller that has some of its fins/blades deformed because it has not been used

My Mercrusier is 10 years old, only gets used over Christmas and has never had an impeller changed.
Current outboard is 2 years old and impeller is fine.

[poly]

hmmm very suss, all u can do for now is change the impeller and see how it gos,

of course it is possible to get a new part that is faulty from the start but as j.g. said i think i would be checking the thermostat as well
The water pump, looks lile its working, plenty of water with good pressure, but the water... its one second hot then it cools down the other second then it gets hot again and again....

the more i think about it i would say it is the thermostat or a blockage of some sort
just how hot dose the water get???????

Think so Freddy & whilst you're there take some notes on how to read all reply's written in these sorts of threads

Think I gave a very good possibility as to why the water pressure dropped when boris said he put the motor into gear in one of my early reply's.

Think the prob most people make in these sorts of threads is they base their reply's on the original Q asked & dont stop to look @ any other possibilities.

Very hard for an impellor to just shat itself unless of course you have a fuel blockage

Now where's Fed to comment on that one ???

[quintrex101]

My Mercrusier is 10 years old, only gets used over Christmas and has never had an impeller changed.

your bloody hopeless you need to go back to school its Mercruiser not Mercrusier ..... need to put that i in front of the s

ok guys,

Because i coldnt be bothered to do it myself (working hard nowadays) i decided to take it to my mates mechanic (mine is busy for the next 2 weeks!!!!! what the...)
Anyway i thought it might be a good idea because i wanted the motor checked by another mechanic. The water pump and thermostad are changed and the gearbox oil. The mechanic said the motor is in top condition. He thinks the motor looks like its been hardly ever used. So yeah... its all good...

Now its time to start working on the boat...
to do list...
Cleaning
Put the second swiwel seat
Live bait tank. I want to use one of underfloor areas as a live bait tank.
Cutting board. Over the transom.
Under floor fuel tank,
rocket louncher
Carpeting

The fun starts....

Daniel, Daniel, Daniel, that was a typo. As KKW said you Twit Top. OH bugger I did not forget the s

So Boris we get half the info and now we will never know what caused the problem.
I don't know FED but if he could chime in now I'm sure all would be solved.
