Clutch cone? I had similar issues when I bought my boat, but not
identical - when in gear it would slowly engage, once engaged it would
stay engaged. Reverse was fine. Had to get the cones lapped, the
surfaces were seriously glazed. Which meant pulling the transmission
for an overhaul...
Note, pulling the tranny wasn't a big task, took an hour or two and the
same on re-installation. I did that part, a friend overhauled it for me.

The last time out I noticed some strange behaviour when motoring.
Basically, I got very little drive from the prop until I increased
revs pretty substantially (around 2000rpm) and then it 'caught' and I
got normal speed from the revs, and am able to throttle up or down
appropriately. If I brought the throttle to idle (in gear) at speed,
I would have to do the same thing to get it to 'catch' again. I
didn't have time to do more diagnosis at the end of the trip, but will
do so when I head to the boat this evening pre-race. Reverse worked
fine backing out of the slip.
I'm thinking either its a transmission problem, or the propellor
(2-blade flex-o-fold) isn't opening when it should. I'm going to
check the shaft speed in-gear at the dock, which should tell me
which. If it turns out to be propellor, then I'll live with it until
the end of the season; if it's the transmission, does anyone have
ideas about where to go next? Gear oil was changed at the beginning
of this season, so that shouldn't be the issue, but I'll check levels
etc. The engine is a Yanmar 3GMF.
Thanks,
Tim
