View Full Version : 1999 Yamaha 30hp mod # MSHX Water in lower unit

07-05-2003, 10:19 PM
"A short time ago I noticed a small amount of lower unit oil on my concrete & noticed it was coming from a small hole on the forward part of the lower unit casing above the hub.

I now have water invading the lower unit & would like to know how to correct the problem. When I tried to flush it out & refill with new oil it was coming out of 2 small holes on the forward part of the casing while I was refilling.

Can or should a do-it-yourselfer try to correct the problem?

Any advice would be greatly appreciated!

" Randy,

It sounds like the shift rod seal may be leaking, but you have to pull the lower unit in order to identify the problem. You could probably repair this yourself.

" Thanks Tonyob,

I looked through the parts catalog & didn't see a shift rod seal on the parts list. Would it come with the whole shift rod assembly when ordered? "
