Re: merc 525SC's
Glassdave, I have a friend with 525s and they are very reliable. Lots of wot time, and over 400hrs of trouble free operation. We added chillers and pulleys and picked up a minimum of 5mph in a 33ft boat.

Re: merc 525SC's
If you have to freshen them, call Tyler Crockett, he can sell you a cam package that can make 600 hp without an intercooler. This is one sweet package. Ran like EFI. He sold me the components as cheap as I could get anywhere. Will require mild head work.
