I rund the Merc 600SC fuel pumps on my gen6 engines, I had 600 hp last season zero fuel issues, how much HP will that pump feed safely? I am shooting for 675-700 it looks like, I do not want to run Electric if I can avoid it.

I run the KE pump heads rated for 120ghp on my mech pumps with 0 issues close to 800hp

i believe a merc 600 sc pump is a carter 130 gph. im not impressed with them, i would look for a holley pump with more gph. the merc 800 sc ran holley 180 gph

I have run the KE pump head for about 8 years also. If I use anything but Shell 93 the boat coughs under load. It has not done it since I switched to the Shell 93. I have between 550 and 575 hp.

You have dart blocks now with fuel pump provision?

I'd go with a pump like this #9373

Hmmm I was hoping to just use the sea pump ones because I already have them, joe that link I just see oil pans and such? Think I should go
Back to other style pumps huh?

icdedppl dan has a pair that i think are brand new that he is not going to use.pm him and check.

Cool, thanks.... I just bought his breathers, I guess I will have to find sea pumps or block mine off, just sucks I am plumbed for the sea pump driven pumps, it's not the end of the world though.... its just added to list haha

You need to click "parts" at top right of screen, then click "mechanical fuel pumps"

Duh, also sent Dan a message to see, I may have to buy that stuff later but looking into things I need now...
