- Twin 454 mercruiser, hurth transmissions
3 days ago my Starboard engine ran out of fuel. If going by the gauge, I should have had enough gas. Our 1990 350 express cruiser has not had any engine problems. It has a primary and secondary fuel filter. I just serviced the engine, changed only the secondary fuel filter. Im doubting the problem is the primary, but I'll start there. What troubleshooting steps should I take from there? Twin 454's, mechanical fuel pumps.
