Hey all, could anyone find a lowerunit/prop diagram for this motor? I have a couple questions for you guys but a diagram would help me with knowing what im talking about. Im only 16 and working on motors is a lot of fun so please help me out.

Wow thanks a lot. Not gonna lie, that is a bit confusing to me. I have a broken seal on my motor and it has been leaking and im just curious where in the motor this takes place? Also, is it expensive to fix something like that? thanks a lot

Which seal?

[CAMAN]

The two main seals are #18 and #72

Leaking where?

Lower unit?

[FBMH]

Yes, it has been leaking from the prop/lowerunit. I have been told there is a broken seal.

Are you positive it's lower unit lube? Some people mistake oil leaking from the prop as a bad seal. Most of the time it's unburnt 2stroke oil in the exhaust and will do no harm.

Dip your finger into the oil that's leaking and smell it. If it has a gassy or burnt smell it's probably just oil in the exhaust and wouldn't worry about it. Also check the lower unit lube, is it milky or seem low?
