Filled both tanks with fresh fuel for a 55 mile run last weekend. So yesterday was out for a short cruise and stopped and threw out the hook for a swim to cool off. Stayed about an hour and when I went to start engines, both would crank and crank and crank and then fire and bogg down and quit running. First initial thought was I had taken on bad gas, but I ran through a half tank with no issues and the boat was running great prior to stopping to anchor. Pulled the starboard water/fuel separator to inspect the fuel. The fuel looked clean no water or cloudyness. The smell of gas was present so I assumed maybe flooded, so I waited a while and tried again. This time port motor fired and continued to run, starboard motor would not fire. So limped back to the harbor. Both water/fuel separators were changed in the spring and both motors had tune-up this off-season.
Going back to the boat tomorrow to troubleshoot. I will try to start it first and then I was going to pull the plugs to inspect them for fouling.
Does anybody have experience with these engines and this particular problem? Any advise on what else I can look for? I don't know much about vapor lock, but seems strange both engines acted the same upon restart and then eventually the port engine fired and ran fine back to the harbor. Could these engines experience vapor lock and if so what is the cause?
Any suggestions are welcome.
