Thinking of running a crossover
So I'm thinking of running a crossover for looks. I would like to get rid of the Merc thermostat housing and water pump to clean up the engine. I just have a 400HP N/A 468 and boat has not gone past 67MPH so I don't think I should have water PSI problems. Will this just be a quick and easy bolt on for me to clean up the engine?

Now that's what I'm talking about!! Very beautiful clean looking engine Deep!!! My engine looks like a freaking Octopus right now!
So it looks like you also have Gils? So do you just run from the thermostat to bottom of manifold and then manifold to riser up top?

If you have a standard water pick up off your bravo drive you should be fine. Through hull pick-up's and some of the Imco drives can/will increase the water pressure. Simply fixed with a pressure relief valve if that's the case though. Cpperformance sells a complete kit for around $300.00 The kit I bought came with a 1" bypass hose also. It's real clean looking too! Depending on how your belts are ran, you will probably have to replace the belts as well and lengthen or shorten your hoses to the exhaust manifolds.
Here's a pic of my crossover set-up. I use a different thermostat housing than the one that would come in the kit. The one in the kit is a nice piece though! Looks like The Deep and I use the same housings. I opened up my bypass hole on mine from 3/8' npt to 3/4' npt.

Yes I'm just using the pick up off my bravo drive. The $300 kit from CP is the one I'm looking at. I was going to replace my belts and hoses, I have never replaced them and I don't know when the last time the previous owner replaced them.

The bypass feeds water out of the crossover through a hose up to the thermostat housing. There's an inlet and 2 outlets that sit above the thermostat on the thermostat housing. From there it feeds to your exhaust manifolds. If you didn't have a bypass, your exhaust manifolds wouldn't get any water until the thermostat opened up.
There's a real good pic of the bypass in the pic I posted.
