Circulating pumps are good for stock engines- in fact, it allows them to run better and last longer since you get them up to a proper operating temp- no chance on running cold and scuffing parts thru tight clearances. Blower motors need lots of water volume to stay cool so the circ pumps will hinder you. The systems with crossovers and stats are a good compromise.
Remember, removing the water pump removes one more mechanical piece that can fail & strand you.
If you do alot of idling and not going over 400 horse, I'd keep the pumps.

i removed the circulating pump on my older boat w/525sc type motor and pput a crossover on it and it works well,keeps the temps down.i wanted to put the same crossover on another boat i own w/502mpi mag and was told not to.my engine guy said the engine will run cooler and mess up the engine or would not run right because of the motor is computor controled.hope this helps.

I'm going Back to Circulating Pumps, I've been told numerous times that you can get hot spots with cross overs.
And you can prevent that with Circulating Pumps.
Down side is they may not look as cool, but I did find some nice Billet ones. Check the link out.

I ran circ water pumps on my 600 NA motors with raw water cooling. Still do but have closed loop cooling now. Merc uses circ water pump on their 1200 SCi motor. I guess there is something to keeping block at temp but there are lots of people who run crossovers successfully. I would like to see some knowledgeable members weigh in.
We all boat in relatively warm water during the summer, maybe Merc is looking at more varied water temp conditions with the circ water pump, tstat and the rest of the water system they run.
