Im thinking of adding closed cooling system to a boat Im buying. I operate in the salt water 100% of the time.
Does anyone have experience with these and are they worth the money?
The engines I want to put them on are the Mercruiser 350 Mags.

Thanks

yes, in salt water a great idea...saves the engine and manifolds...

Give a call to Mr.Cool they advertise up here and can answer all your questions plus have good prices.

Thanks for the help guys. I will look up Mr. Cool.

Here's an option as well http://www.keitheickert.com/p-14010-...o-360-cid.aspx

With the EconoCool system I still use sea water to cool the manifolds? With the closed water system how do I do flush the manifolds?

The KEPP ststem would take the water from the heat exchanger and run it thru the exhaust manifolds and out.

A fully closed system would also run antifreeze thru the manifolds.

How do you think you cool your engine??

There is no need to be an a$$...

Well I rather be an ass and make him think before some else is an A$$ and takes his money for a simple flush. This is a No-brainer.
