What kind of speeds were you seeing in yours, cruise and wot? This one has 21p mirage 3 blades on it now which lead me to think the drives must be 1.36:1. I don't need a speed demon but I'll be running with 2 353's, and 1 312. The 353's have 496 ho mags and 502 mpi's. I'm thinking I should be able to hang with them.

The HP465 was a 502, GM Rect ports, Crane 240/250*, 559/578 Lift, 110LSA. It used a dual plane GM aluminum intake, and a Holley 800DP.

Basically, its an HP500, but with a flat tappet, and dual plane intake. The HP500 made similar power, except used a roller quite a bit less aggressive, and a single plane dart intake.

great motor, nothing to be worried about. it's a true "blue" merc motor. 5 hp less than the 500 hp that came out in 95

Thanks for everyone's help! We just got back from looking at the boat and if it all works out she will be ours!

just a heads up..get into the engine compartment and look under the steps..now look at the area where all the hose's go through the forward bulkhead..wonderful formula only used wood and not glass on that bulkhead and just tabbed it in around the edges with fiberglass.when they cut holes in it with holesaws for all the wires and fuel lines they used these plastic through fittings,,look real close to that bulkhead they rot out and then the rot goes all the way through the cock pit to the bulkhead in the cabin..also go into the cabin and lift the step and check in their for rotted wood.. bring a dead blow hammer with you and give it a wack..also if you see bad areas run,,dont think its a easy fix..if its all good i would have those areas glasses in...espically the forward bulkhead in the engine bay..

Thanks fixx. Everything appeared to be rock solid so far. The next time i go ill double check those areas. The storage under the step is as immaculate as the rest of it.

It had the same compression ratio of the HP 500 of 8.75:1 -along with the GM Forged steel Rods, JE forged pistons and the GM forged steel crank. Yep the cam was a Crane Hydraulic NON roller. It used a GM Aluminum Dual Plane intake manifold.
