Just started sailing, and this may be a stupid question...
2-stroke
Nissan 3.5
motor (1992). Fires up fine. Runs in neutral fine. Goes forward fine...for about 5 minutes. Then it slowly decreases speed on it's own until it dies. Then...when I restart, it dies quicker and quicker.
I've got the manual...gas mix is correct. Starting procedure is correct. Warming up is being done...letting air in is done...etc.
Seems like it's not getting enough air. It's spitting out
water as it should, so it's no
overheating.
Thoughts?
