Thanks...that's what I thought, just haven't been able to find any pictures of it done. I've got Merlin intakes on my motors so there should be enough material to tap into.

Or you can dump water off the rear of the intakes overboard. You can adjust diameter of these lines, to help dial in water pressure as well.

i don,t understand how removing the circ pump will cause hot spot in rear of head,can someone explain that to me?

Cool...thanks for the input. Doubt I'll have much pressure issues as I'll be lucky to see 70 mph out of my boat.
OP...didn't mean to hijack your thread bit seems it's all useful info for running crossovers.

I'm not sure either....had just read it so was curious if anyone had any input either way.

lot of experts with no experiance giving advice lately.the circulating pump slows down the water flow through the engine.removing it in no way will cause the back of the head to have hot spots.if you remove the circ pump you will increase water pressure due to MORE water entering the block.merc uses the circ pump to help the engine maintain constant water temp and to reduce water pressure.

If removing the circ pump resulted in lower water pressure steam pockets would form at a lower temp.

no,it does not lower pressure enough to do that,if it di merc woild not use the circ pump.edit in,i was watching the bears win and not thinking,removing the circ pump will increase water pressure,not lower it.

I think the main reason mercury used a circulating pump, was so when thermostat was closed, water would keep "circulating" thru the engine, via the byass hose. Water never stood still in the block while thermostat was closed, it simply went in the front of block, thru heads, back out intake into circulating pump, and back thru front of block again. The extra raw water coming in during that period, simply went out the exhaust. The system works well, and imo, if running a thermostat, its a better way to go, having a circulating pump.

The OP said he likes the look without the ugly merc t-stat, I believe. If looks are your goal Diamond also offers a few nice polished stainless replacements for that ugly t-stat housing and keeping the circulating pump.
