I like these pumps. Can get them with the USCG vent tube also.
Clay Smith pumps are the original 6 valve pump and flow 140gph.

I looked at my earlier post and that didn't come out right. I meant WOT is the perfect speed in any boat. Whether it's 20mph or 200mph. Faster is better though!

I have CV products pumps on my seawater pumps with about the same power. I tried some of the other pumps, but none would maintain fuel pressure. The CV is expensive, but with 3 internal valves instead of 1, it will easily supply your engine. It is also a simple bolt on!

Carter HV bolt it up to the top half of the stock merc pump. Less than $100.00 and run all 1/2 inch lines.

Good point, just make sure the upper rubber and spring are in good shape. They usually develop rust in that area.

Just wanted to put my $0.02 in: The electric Holley's work, but they are the loudest poorest built pumps out there. The Mallory is gear-rotor which is quiet and same operation principle as some oil pumps. Mechanical seems good, but the idea of something else flapping back and forth at 5500rpm (actually 1/2 that for fuel pump pushrod off cam lobe) is preventable with something that just spins in a circle like an electric. My vote is 1. Mallory, 2. replace the bottom half of stock with Carter HV as mentioned above. Aeromotive seems cool, but their hour rating is kind of short for expected life.

I ended up getting the electric Mallory 140 Marine pumps and the Waterproof Painless Wiring kits. I think all I need now is the oil pressure safety switch and I will be good to go. Mallory's instructions say nothing about running a return line on this model pump??? Anybody running them without a return line?

You don't have to run a return line, pump has built in bypass, just have a good regulator. If you run the mall 110 elect you don't need a reg.
