Mercruiser 305 year 1989 <br />Ran the boat for about 20 min under power. Stopped for about 10 minutes, tried to start up engine but would not turn over. The engine cranked but nothing else. Tried starting it with trottle full open , noticed alittle vapor come out of carb. , I assume it was getting gas (not positive). I thought the engine was alittle hot but temp gauge was normal.<br />End up meeting Sea Tow.<br />Went to boat today, checked out the circut breaker, that was fine.<br />Cranked the engine and it started right up. The engine temp again was fine, the only thing I noticed was that the oil pressure seemed higher than normal 60-70 .<br />I made by way back to my slip and the engine cut out. I was able to restart only to have it cut out on me. Mostly the stall occured when going into idle or reverse. I rasied the idle alittle but it then cut out again backing into slip.<br />Once docked I tried to start it again but nothing.<br />I may have a defective temp guage- but no signs of over heating.(I have a closed water system), or I am thinking the fuel pump is going. My manual says its equiped with a sight tube which will give evidence of a ruptured pump diaphragm. I didn't notice this yet, I think the hoses are all black anyway and nothing visable.<br />If it is the water pump, why would it start? <br />Any ideas to this post would be appreciated.
