thanks for any info

Doesn't leak like a stock circulator pump.
Also, save your money.

OK, a circ pump cannot pull water, it has to be fed. So, if your seawater pump takes a dive, it does you no good. If the circ takes a dive, at best you have water spraying everywhere, at worst you have a busted belt. Sewater pump cant force water past the dead pump. So, why kee the circ pump??

Spend the money

I went with them when I put on blowers eng will run cold you will need one with a bypass to run a tstat. They make for a very clean looking eng they also can cause hi water pressure in some boats. I use a 5/8 restrictor no tstat and run 20 psi with no problems.

I run a bypass. When doing my engine swap, I couldn't see buying a new pump and then have to worry about it and the belt. For about the same price I switched to the crossover with t-stat and by-pass and have been very happy with the choice.
And it looks cool.

Everyone has there preference. Me too. You will see no power gains. If it is EFI I would definitely NOT run a cross over. Stock recirc system works well and keeps engine temps up and no water pressure problems. A big ZERO on cool looks. If you decide to run a cross over plan on spending some time fine tuning water pressure, temperature and evening out water flow to both sides of the motor. Just my .02

The big painted cast iron t-stat housing with the elephant trunk hanging off it looks much better than the polished stainless parts???

Stock pump set up is a ZERO in the looks department. Sorry I was not clear.
