FIRST CLASS ACT, in my book

tic toc.................... that's all for now....... tomorrow may be different

So with an '08 Engine with 40hours on it should you just bite the bullet and change them out now? It is a 29 Fever with a 525EFI.

Yes absolutely but as of right now I personally can not recommend a replacement. It depends on how this goes....

I wouldn't. My '07 525 hasn't had any header issues.

Yet.....but if/when they fail and you shell your motor, how will you feel then about a 5k insurance policy?

Diffinately run in OPEN exhaust mode though all the time correct?

Q & Q is only for idle with a 525. Mercury shop manual says up to 2,500 rpm.

"Yet.....but if/when they fail and you shell your motor, how will you feel then about a 5k insurance policy?"

I'm not convinced that all 525 CMIs are destined to fail. Maybe I have to learn the hard way but the CMIs are staying put.

either you have not read of the hundreds of cracked inner and outer tubes or you have deep pockets. regardless it's your boat and your decision. have fun out there!
