Looking to replace and move the location of the heat exchanger on my M25XP to a larger exchanger. Does anyone know where I can find one?

There are many aftermarket 3" heat exchangers but the location should not need to be moved. The existing bracket can be carefully bent and re-used with some AWAB hose clamps and some silicone gasket materials between the HX and bracket.
I often buy them from Mr. Cool, (often made by Seakamp)... Be sure to check your "upgraded" part number and cross reference it to the Mr. Cool number. They sell high quality HX's for a LOT less than Westerbeke.......

There is also Lenco Coolers and a few others that escape me right now.....
The M25XP came with a three inch HX which is fine for the boat. I installed a three inch HX on our "plain olde" M25 to replace the OEM 2 inch HX.
If you have the bracket Maine Sail described, with the big hose clamps, be sure to install a vibration isolation device between the bracket and the HX shell (body) - we used a bicycle tire inner tube - cheap insurance to avoid having the bracket cut into the expensive ($300) HX shell.

Hi Joe,
I'm curious why you feel you need a larger HX? I have an 86 O'day 35 and my boat came with a 3" HX and it never runs hotter than 190, even during the summer and when I'm motoring at 6 kts.
Two years ago I did remove my HX and had it cleaned out at a radiator shop. There was a decent amount of scaling in there before and it came back like new. The price was $50 and was well worth it.

We are planning on our retirement and living abord in much warmer waters and I don't want to run into an overheating problem.
