outboard repairs
Submitted by Shane O on Fri, 2010-01-29 10:30
i brought my boat with a 55hp tohatsu, there was a little milky oil leaking from near the prop. took it to a boat repar shop, they tried to sting me $1000 maybe more in repairs.
after a bit of searching and a few phone calls have now got them only replacing the gearbox oil, i don't know alot about motors. i do know the motor had not been run for 12mths before i got it, i have used it twice and both times had just switched off and not let the fuel run dry. so maybe it could be a build up of feul and some water may have got in there?
so i am going for a second opinion, don't think there is that vmuch wrong with it.

well i read the other post
on your motor. and you said on this post again that the boat previos to your use has not been used for a year, you also said it was runnin on one carby and that you dont let the fuel run dry, fuel could have bolcked up the other carb. but theres no way that fuel could have got into the gearbox
and its leaking geabox oil which is a milky colour which (ithink) is water in the box and that your only getting the oil changed, if its a bad seal straight way water just gonna get in the gearbox again and more milky oil and is just gonna ruin the new oil, the seal needs to be changed or whatevers leaking
on a 2 stroke you should run it dry after every use or the carby will gum up.
if they only change your oil when the seals leaking i dont know how smart the mechanic is, but if it leaks after this then you just get new seals

Can you confirm the dry running at the end of the day for a two stroke is the way to go , I was advised not too ???????.
Ol Yella, A good outboard mechanic is Outboards WA he is in Cannington works from home and advertizes in the Quokka , never had any issues with cost and quality of work over many years .
But Iam inclined to agree with Wide Open sounds like putting new oil in aint gonna fix it, sounds like a seals gone ???????
Good Luck

if you leave fuel
in the carbies the fuel evaporates leaving large amounts of oil in the carby which can block them up , it dont take long to just pull off the bowl and check your needle and float are not sticking and spray with some carby clean. as for the milky oil your prop seal will need changing as thats where they usually leak from , seaweed or fishing line around the prop will stuff the seals straight away. as for $1000 to fix i agree it sounds very expensive i would have thought max of about $300 for the whole job

my grandad prevoisly owned a 80hp mercury 2 stroke a ran it off for 20 years with no probs.
we continue to do it on a 30hp mariner auxilary.
have seen people run off 2 stroke dirt bikes
note these are all premix engines
and i know nothing about runnin off oil injected and direct injected engines.
its worked for us but if the mechanic said not to do it for your engine and you arent and its working for you i would probably keep to what youre doing

Don't run your carbies dry.
Don't run your carbies dry. It just makes the problem of gummed up crabies happen quicker.
What colour is the oil? Is it milky or golden colour or is it jet black and smell exhausty? It could be just unburt oil leaking down from the exhaust. Especially if your mixing your oil to fuel ratio a bit rich.

Oil Change
Just changing the oil isn't going to make the fault disappear.If there has been water in there for any length of time there is probably damage to the bearings as well.
The mechanic may have to drop the gearbox off and check all the bearings,seals on the drive and prop shafts.Quite a bit of labour is involved.Ask around but I think they are all going to tell you the same thing.

i dont understand how run running the carbies dries would gum it up quicker since you run off all the fuel/oil mixture thats been through the carby instead off leaving it to sit there and wait for the oil to get thick and gummy.
people we know have used this method for decades with no probs
seems like other members of fishwrecked have no probs with it also

Fuel and oil in your carby.
Fuel and oil in your carby. Fuel evaporates and leaves oil behind that's the problem were trying to stop. Okay when you "so called run your carby dry" you will find that you actually haven't run it dry. You have only run it low, low enough just so that the engine will no longer run, but there is still a mix of fuel and oil. Less than before and you now have less fuel to evaporate therefor leaving just oil much quicker than if the carby had been full. Only way to really run carby dry is to use fogging oil and spray this into carby air intakes whilst running.
Also not to mention that you've just run your engine with no lubrication, allbiet only for seconds.

remember 2 strokes run on premix(premix 2 strokes)
the oil is not seperate its mixed with the fuel oil main thing we want to clear by running it dry is preventing the jets becoming cloged, if youre that worried about that very small amount of fuel and oil left behind drain the float bowl because thats where its going to be left over, the oils not going to be gunking up jets
how could you run the run the engine for a few seconds with no lubrication if the oil is mixed in with the fuel, of course before you use a premix engine you should always shake the fuel tank a bit to mix it up again
i've never had a carby clog up so i'll continue to run it dry

What happens is the oil is
What happens is the oil is left behind in the bowl. When you go to use it again new fuel and oil picks up small clogs/chunks of oil and sends it through and blocks the jets. Happens all the time. Best way to stop this happening is to run your engine at least once every month.
Fairly simple really. May never have happened to you but that's not to say it doesn't happen. This is the main reason after a engine has sat for any time it often won't run correctly and the carbies need cleaning..

You have to drop the leg to change the upper gearbox seal
Its located below the water pump requiring you to remove that assembly to get to it.
Ive done it before, it can be a bit of a pain in the backside....i wouldnt do the job for someone else for under a thousand.
If theres milky oil in your gearbox it definately has water ingress, your mechanic isnt lying to you. It can either be through the upper or lower seals or could simply be the copper washer on the fill / drain plug allowing water in (unlikely)
If you cant afford a proper repair you should as you have done change / flush the oil to remove moisture from your gearbox gears and bearings to stop rust, untill you can afford to get it fixed (asap).
Gooooone Fishin!

outboard repairs
it has nothing to do with the fact i can't afford the repairs, i am not going to be taken for a ride. he charged me $410 to take the engine apart, change a couple of washers and change the oil. and change a plug. he didn't even change any seals.
i don't know about anyone else but i am not prepared to ripped off, i have a mobile mechanic (arthur page) changing the water pump and the seals in the gearbox for around $250.
i can't justify wasting my money for his ego asnd lies...
