That's good advice Jim, thanks. I was also going to ask if you had the electric pump in addition as I have seen that on some boats. My boat does not.Pete
We have a little over 6,000 hours on our 3QM30. Still working fine. I would recommend that you carry in your spare inventory a fuel lift pump. Over time the pump membrane becomes porous and can't supply enough fuel at idle speeds. With a spare on board you may save a cruise. In 30 years we've replaced ours twice.
