Hi guys,
I just got a new boat, and after 1 full day of running fine I am now beginning to have some problems getting it to start. The motor is a 2005 Mercruiser 5.7 MPI, with a Merc B3 outdrive.
When the problem occurs, it is after the engine has been running for a while. When cold, it has started fine each time. When warm, or after an extended period of being off (still warm), it won't start most of the time.
Yesterday I was able to get it started after gunning the throttle a little. When it cranks it sounds like it is about to start but then dies. Then we can usually smell gasoline.
I have had no problems with overheating, and the electrical system seems to be charging fine - judging from the guages. Engine performs well once it is started. I started running it without shutting down yesterday, but that takes a toll on the fuel level.
The previous owner changed out the ignition switch right before he gave me the boat. Not sure if this could be the problem. I am wondering if he wired it incorrectly. Could the fuel pump be running after shut down? I have not heard anything running that shouldn't be.
Also, I transported the boat 800 miles to get it back home after purchasing. Could this be a vacuum issue? Maybe the long trailering shook a vacuum hose loose? Any help would be appreciated. Thanks guys.
