Actually you DID say "clean up" and I knew what you meant.
I've seen it go both ways ..... Both with a "well known" fellow doing the work.
As long as he really does have a good understanding of what works well for a marine engine you are likely ok but sooo many people want to build a boat engine the same way they would a dragster. Just saying be careful mate.
