I had a customer with your same symptoms and too much fuel pressure was the problem because of that little screen. Glad we could help!

Great to hear you got it fixed. Always cool when people post the outcome. I love this site.

I have zero idea why that screen is there on the return side, being as it's filtered fuel already into the pump, and the return line goes back to the filter inlet housing anyways... purty dumb idea actually. It runs soooo smooth now, it's incredible. I decided to continue in maintenance mode and checked the impeller just 4 grins, found it was cracked on every blade, and 3 blades were missing completely right to the hub. Never ran over 160* yesterday, still pumps good water out the pipes... Backflushed both cooler(s) and inlet lines for debris. One blade went somewhere, one was in the inlet slot and one in the outlet slot. Dealer said he put a new impeller in it b4 I bought it in October, but this pump has never been opened up since 1998 new, it's a sealed and factory painted original pump... what a liar that Boats 'N Such A******* was. Good thing I checked the impeller b4 going out again. Boat now has only 68 original hours, and it's extremely clean.

thanx again, Jim

Was the pressure regulator screen dirty?

Good question R... dunno.... I dropped the dammm thing in the bilge due to it's bastard location under the motor mount. I haven't seen it since... I was more worried about not dropping those 2 miniscule metric screws than where that mini-mouse little filter was going to go.. Why does Mercruiser always hide basic maintenance items ?? if this was a tight twin boat, the engine would have had to come out to remove it. A lot of hassle for a $1.50 part.
Ed, I owe ya a case of beer. Lemme know, your close enough..

Glad it was something I had run into before. The 34' SeaRay I worked on was so cramped that I had to remove part of the exhaust so I could fit down between the engines to change that damn little screen. Had it been the other side, the generator was in the way.

While I cursed and swore during the whole job, it was worth it all when I saw how nice that engine ran!
