Ive not bought one in years, what would you recommend to support 650 hp, to be driven off the sea pump

thanks

I would look into C&S. great pumps and real nice brackets

you can buy the Baker and install the diphram part onto the merc base, at least that's what I was told when I was looking, I ened up doing Dart blocks and was able to just use the pump As is..

Any bolt together style pump, you can bolt the bottom on to the merc top. I used the jegs 170gph with a Holley regulator and it has worked very well.

A holley 130 gph is all I've ever used.

Im bringing this back up, went into my local speed shop ( Star Performance ) looking for a pump, looked at the Holley 12-454-20 and told them it was going to mount kinda upside down and they said no way ?? Im ready to order two of something but dont know exactly what. Sea pump mounted

Why wont they bolt directly to the sea pump, new complete unit ?

Edit: this one ?? ...http://www.jegs.com/i/Holley/510/12-454-20/10002/-1

The merc sea pump style pumps, use a different arm than a regular bbc style pump

I should of known they'd pull something like this, thanks .....

I've just used the bottom of this pump bolted to the top of the merc pump. Seems to work just fine.
