New to boating and to this forum, any advice is appreciated.
I have a 1976 Grew 164 with a 170HP intercooled Mercruiser. The boat sat for several years but is generally in good shape, I know its history and previous owners and know it was well maintained. After working through some problems this summer the one that remains is that after the motor is warm it stalls going from neutral into gear, it will also stall at idle either in neutral or in gear. One time while tubing and the motor working hard it would not go into neutral but other than that one time it will go into neutral but have to get to 2000 RPM right away to keep from stalling. When warm and in gear it will not run at idle, keep the revs above 2000 and it will run all day, lots of power getting on plane. When I go into neutral when warm then back into gear I can hear it engage but then sputters and dies. When the motor is cold everything works fine, no problem at idle in gear or neutral and no problem going from neutral to gear.
Wondering if there are any ideas out there, I am not a mechanic or even a weekend mechanic. It would seem if it was a carb problem it would run bad all the time, not just when warm but I am not sure. I have also been reading about the interrupter switch and wondering if this might have something to do with it, although it seems that effects going from gear to neutral.
The river is almost frozen here on the east coast of Canada so I have the winter to figure this out, any ideas would be great.
