Evening, who is producing a closed cooling system kit for 750hp ish power? I see a lot of 500hp and some 650hp but havent seen much in the way of 700-800hp stuff. Does anyone have a leed for a reputable system? Thanks.

you just need a large heat exchanger, there is a company in NY Mr Cool I think that sells oversize ones(I bought 2 years ago and still using them ) and you will have to make up the rest, not a big deal, you will have to run a circulating pump if running a crossover now. Its not bad after you mount the exchanger

Ok, yeah I think yesterday I followed some thread links to Mr. Cool website. Thanks

Whipple recommends this company when the stock Merc setup is not enough.

Ayuh,.... Unless ya got a Brand New motor, don't even think about addin' closed coolin' to a used motor, especially if used in the brine,...

Hhmm... 50hrs?

Thanks, I think I roamed onto your site last night. PM sent.

You could try Savage Manufacturing in NZ. The boat I have came with Savage oil coolers so when it came time for engine coolers I chose to keep everything the same the fella down there seemed to ask all the right questions hp level, ambient ocean temp, how we wanted the inlet and outlets arranged etc you can get horizontal or vertical units depending on your space they are all custom built to suit your engines cooling requirement.
Stainless Steel,chrome played very happy with my set up.

Hugh, that sounds interesting. New Zealand? Someone asking all the right questions is key for someone not that familiar with how to set up the heat exchangers. Thank you.
