Anymore pics of the IMCO manifolds? I'm interested. ThanksI have these same manifolds on a Bravo I I/O. They work excellent. Very well made piece.

I'm not sure if they'll fit BBC with tall valve covers, and just general condition. They look pretty cleanI believe that was why we put them on. The Mercruiser manifolds would not clear the covers with the spring coolers and tall covers.

How differently do the IMCO manifolds perform compared to Mercruiser manifolds, which look very similar?Night and day.

On the 400hp Mercruiser we did, it picked up almost 150rpm, we were able to go up one prop pitch. Not to mention losing almost 100 pounds of dead weight.

By the time you buy the riser you could by the indmars brand new. The indmar seam like it would be pretty straight forward conversion from logs?

The IMCO are a tuned manifold and the riser mixing is second to none, all stainless and polished to perfection, it was more of a looks thing than a performance thing. They are not cheap (like almost $3k)
I have a bunch of the stuff from the marathon motor installed on that boat.
We built another motor for it, but after my accident we had to sell it off to pay bills. We were going to put a blown 540 in it. It's a good thing we didn't finish it, the boat does 70 the way it is and any faster it would be sketchy AF.
We bought the boat for $1,500 sitting on a brand new triple axle Trail Rite trailer.

That's what the IMCO manifolds came off ofMy valve covers don't look like they have the slope on the bottom half. I'll have to measure from the measurements on the Imco website and get back to you

How do the water lines route on a jet boat with these? My logs have 3 water connection points (2 in front and 1 in the snail) but I only see 2 on the IMCOs.

I am a huge fan of using the exhaust to preheat the water for cooling the engine.

So on this setup water goes straight to motor, through motor, out thermostat housing, into manifolds and travels out through manifolds and into exhaust. I'm not familiar with this setup, also my boat has no thermostatNo, manifolds first, to engine, out stat to risers. It will work bitchen.
