Yesterday, while leaving the harbor, I pushed the throttle forward and my boat got up on plane, only to bog down, then pick up, then bog down, over and over. I found a kinked fuel hose, replaced it, and we were up and running full speed, until I slowed the boat down again. It stalled at idle, and then wouldn't start. I took the fuel pump apart, noticed nothing wrong with it, and put it back together. Same thing. Finally got it started, but only with the engine in neutral with a bit of throttle, I quickly shifted into gear, and was able to limp back into harbor at 2500 RPMs. I flushed the engine with the muffs, but it would only start with a good amount of throttle, and wouldn't stay at a constant RPM.
Sounded like a carb issue to me, so I ran and picked up a rebuild kit, and rebuilt both carbs yesterday.
Still exhibiting the same problem. After trying to start it with the throttle at idle (no luck), I pulled the plugs and noticed that they had lots of black oil sludge on them. Then I noticed that the same black sludge was leaking from my exhaust port. As I was working alone, I was unable to check the spark, however I do have a tester and will check that out next.
Does this seem like a spark issue to you? Engine was recently correctly timed on the water. Also planning to try an isolated fuel source.
Thanks for any help!
