Original blocks were made in France and were of a porous material. They were a problem. Cat replaced those deffective blocks and since then I believe them to be a reliable motor. I have these models in my boat and they have been bullet proof. Tranny service has been an issue but the engines have been strong.
Just my two cents but I'm sure there are as many opinions as there are members on SFC.
Cat screwed up but made good on those bad blocks. I think those blocks were from around 1995 or 6 not 2001. Why do I remember? I bought a set of those early ones. they made good. as far as transmission thats not cat?
I HAVE A PR WITH 3000 HRS STILL QUIET, SMOKEFREE + GOOD ON FUEL. GREAT ACCELERATION OUT OF THE HOLE. I ALSO HAD BLOCK PROBLEMS, WHICH CAT MADE GOOD ON. NO REAL COMPLAINTS . EASY TO SERVICE
