Thanks I’ll look into that. Most of that parts list is the heavy duty parts to handle prolonged higher rpm than car engines experience (main bearings, connecting rod bearings, heavy duty bolts, etc). I’m trying to make a how-to as there aren’t many out there and I want a simple list for the next guy who wants to do this.
The dealer was kind enough to tell me merc’s suggested mounting point of 13 9/16” up the framing sq from keel of boat. That’s the center point for the template to cut out drive hole. I’ll need to mark that and compare the centerline of flywheel and the A/V plate on foot to keel. I’ll measure it out and let you guys know how it’s going.
I was told 600hp was max. I was worried I wouldn’t have enough torque but my bravo3 has a 2.0 (we think) gear ratio. We’ll know more once we tear it apart, inspect and reseal it. It’s the older style without the swept back design. My local dealer told me it’s gonna max out around 55-60mph depending on rpm and be an absolute torque monster with dual prop and 20p blades.
The cam I’m planning on running is a tsp212/218. 437hp @6200 rpm, 418tq @ 4800rpm. I plan to high speed troll 13-20mph most of the time. Other than slightly ported heads, and maybe a bigger TB, there are no other power adders.
I’ll be mating it up to the 454 coupling on flywheel to help mitigate the chance of shearing the coupler apart. Those things are pricey.
I think I finally solved the raw water pump mounting issue to the crankshaft. Hopefully I’ll get through to guy I need to speak with tomorrow.
