KCHOBOAT,
Which Carter pump did you get? I presume you bought the Carter HV pump, then only used the bottom half of it and bolted it to the top half of the merc belt driven pump?
I see that CP Performance sells a bottom half kit for the merc pump, but in my opinion overpriced at $150. I would guess that the entire Carter HV pump you are talking about was under $100??

Thanks for the tip.
Is there a particular Carter HV pump # that you recommend? What is the estimated gph of the new combination pump?
Also, I know that a conventional mechanical pump won't work on the merc belt-driven setup, but never knew what the difference was. Is the pump arm different or what?

The pump arm is different. Holley also makes a marine mech pump that will bolt up to the merc arm. I use them with my twin-750s and they hold pressure fine..

I just ask for a big block pump. Beside the arm the other reason for using the the merc top is for the hose that runs to the flame arrestor. The pump flows about 120 GPH at 6-8 psi.
