I have a 1977 omc outdrive behind a 351 ford.
Electric shift.
Boat & outdrive have 487 hrs on them total.
Have been well taken care of, fluids are fresh and checked and have been maintained in that condition since new ( I've seen the paperwork).

My question is.. twice ( two diff times) when I have shifted from reverse to forward and acc. hard I have felt a bump or two (like I hit a piece of wood) and then a kind of clunk like it went into gear. This has happened while the boat was picking up speed to get on plane.
The clunk felt almost like engaging 4wheel drv on a hill.

It never felt like it slipped out of gear, just like it went all the way in....... maybe.

Anybody got any ideas or know anybody to talk to?

Appreciate it.

Sounds like your upper gearset may be going, but yours is a lot older than mine. But, that is the general description of more problems on the way! Save some trouble and get it looked at. You said it felt like you hit something, did it sound like a nice smack of gear teeth??

Check and see if there is any up or down play in the outdrive trim

Thanks guys!

Doug, it's solid as a rock. But, that is something I never thought of.

Slab, that web site is Way Cool thank you very much! Was a little disappointed no NFR crap though! I might see if they are interested in starting one.
