I have an M40C motor on my pontoon boat with a lower unit issue. The motor is fairly old, I would guess mid 90's but I am not really sure since I am the second owner, but in great shape with compression of 110 on each lung. Late last year the boat began grinding when going into reverse (forward was fine) and after an adjustment of the shift cable the reverse problems were solved. Last trip out last year the engine would not stay in reverse, the shift lever would chatter when it was placed in reverse but if you held it down reverse would work fine.
I have ordered a service manual for the motor and should receive it Monday. My quetion is 3 fold: 1) am I right that I need to tear into the lower unit? 2) I am mechanically inclinded but not a pro, am I fooling myself thinking I can do the repairs? 3) this motor resides at our vacation home (is at my main home now) where I just want to go and have fun, not spend time working on a boat motor... Aside from a water pump rebuild what other services would be wise to do now?
Sorry to be a taker on my first post, but thanks all for the great information you contribute to this site.
Thanks in advance,
Scott
