1000hp SC engines

Tried this in general, but no answers....

OK, I need some input from anyone that can help....I am seriously considering buying a boat with twin 598 cids / 1000hp blown engines with 10 hours since rebuild....I need to know from anyone that has had engines these big/powerful what to expect as far as reliability, maintenance, hours of service, etc., etc. They are operating at approx. 8 lbs boost. What would I have to do to de-tune them to about 800-850 hp? Thanks for any help in advance.

Re: 1000hp SC engines

Easy first step would be to reduce the boost by a few pounds.

8 lbs is a lot of boost but detuning brings its own set of problems. I like the Pfaff 900s.
