I need advice on possible source of oil leak on my Yamaha 9.9. Dipstick shows constant level of engine oil (ie not losing any from there) The leak appears to be coming from a plate which is screwed on to the side of the leg. Any ideas guys??
No photo available at the moment DF - however clivesheps suggestion of gearbox top oil seal sounds good especially as engine oil level seems Ok. Mechanic hopefully looking at it this week.
A small amount of oil seems to look really bad when it enters the water. It`s hopefully only a small quantity. Usually the owners handbook will tell you which is the engine oil drain and the gear check/fill and drain holes. Any upper areas will be from the engine and lower ones the gears. There are plenty of manuals available on e-bay for little money. Paul.
