Re: seawater/fuel pump on Gen VI w/ serpentine setup

Don't know if it helps, but I upgraded my 454's to serpentine belts last year. The seawater pumps with the fuel pump boss had the same bolt battern as the pump without the fuel pump provision. They...

Re: Oil pressure is 80 -100 psi, Is this OK

My bro-in-law has a newer 454 with a high volume pump that runs at 80psi all day long on conventional 20/50. I would say the 50 psi you were seeing before the change was questionable. Was your...

Re: Could not find the thread..

Very cool! That's exactly what I was looking for! I'd rather have a tee for the alarm switch than have the wiring for an external relay. I think the current draw issue on the ignition circuit can...

Re: water found in oil, any hope for engine?

Ok, this is sounding more encouraging than I thought. Anyone know the name of the milkshake-scum dissolving oil additive? Is this something we could pick up at a westmarine/boaus?

Re: electric fuel pump automatic shutoff?

I actually regret making the switch, I may just switch back. The problem with the belt driven pumps is that they failed every other season. I bought the boat spring 2002, it was 4 yrs old. At that...

oid pan problems.

I'm in the midst of replacing a 1998 merc 454 and discovered my stock, steel, oil pan is toast. Replacing with a pan from merc seems pretty expensive ($370!) and probably not what I want anyway...

Re: stuck hydraulic lifters - help!
