Merc Racing 525
 

I'm in the process of selecting engines for a repower. I've been getting a lot of negative feedback from owners of the Merc Racing 525efi. They tell me there are reversion problems with the headers due to the aggressive cam and the heads are damaged within 80 hours. I understand there may be a class action suite?

Anyway, can anyone verify the problem or recommend a good alternative for engines. (Chief, Sterling...?)

Thanks
