HP500 EFI Closed Cooling and HP525 EFI Serial #
Hi All,
I haven't been able to find a closed cooling upgrade kit for the HP500 EFI from Mercruiser. One idea I had was that the HP525 EFI and HP500EFI are both very similar in exterior looks. I'm guessing that it might be possible to buy a set of parts that fit the HP525 and use them to install closed cooling system on the HP500.
Would someone with HP525 EFI engines be willing to send me a serial # from one of their engines? I can use the # to order a service manual and parts list for the HP525 and start researching whether this might be possible.
If you know of a closed cooling upgrade kit part # for the HP500 EFI, that would be even better.
Thanks,
Garrett

Innovation Marine in Sarasota FL, does a great job with closed cooling on their setups. They have rebuilt some 500efis that I have seen with closed cooling, and it looks amazing. I'll email you their number tomorrow.

I left them my number. They said they would give me a call back and let me know what they come up with. I'll keep you all posted.

FYI
The HP500 and HP500efi use cast iron heads, while the HP525 uses a aluminum head with water ports on the faces of the heads where the heat exchanger is plumbed too. Now I'm going off memory(of 525's i've seen), but I'm 99% sure this is how there setup. So a HP525 setup wouldn't work anyways.
