A Clean Machine
2: Recommissioning a gasoline inboard, and more
I lay up my gasoline
inboard boat every year. In the past, when recommissioning and running
the engine, it backfires and runs rough at 3000 rpm. I have noticed sand-like
material accumulating in the fuel filters. What is this, and how can I
prevent it from happening again? R.O., via e-mail
To avoid this, when you’re ready to put your boat up on the hard, turn off the fuel lines to the engines and run the engines until they’re out of fuel. (Do not do this with diesel, as severe injection-system damage can occur.) Now you can winterize as before.
I’ve been having trouble with my tender’s outboard, and I would like to determine whether the problem is in the boat’s fuel system or it’s in the engine. Any suggestions? L.N., via e-mail
Try connecting another fuel tank and line to your engine. Make sure both are free of any residue, old fuel, or corrosion and that the tank is filled with fresh fuel. Run the engine, and if the symptom is eliminated, the problem is with the original fuel tank and line. If the symptom is still present, however, then the problem is in the engine.
While trying to loosen
several nuts on some bolts, I managed to strip some edges on the nuts.
How should I proceed? S.G., via e-mail
