Boat is a 2008 Chaparral Signature 290 with Volvo 4.3 OSi-JF engines.
This has happened to me twice now. Where my starboard engine dies and will not start while out on the water. Both times it was the fuel pump relay. Both times you could tell the relay was scorched as the plastic had some heat marks on it. I replaced the fuel pump already with a unit from Amazon, not the newer style without paint on the inside.
Same engine, same relay, and actually right in the same spot doing the same thing! I was looking for a crab trap that I had dropped earlier that morning and lost 1l2 traps there now.
I suspicions are something is causing the fuel pump to work harder than it needs too and draws too much current through the relay. The fuel filter is a year old (gummed up?), clogged fpr? Bad injectors? Engine runs fine, easily hit 30 knots on the run. Any other suggestions?
Thanks
