As I said you pay your money and you takes your choice and to be honest, I just know I wont buy another Honda 4 stroke as I genuinely believe there are engines out there more suitable for RIBS.

I have the misfortune to own a Camel boat and am very disappointed with it in terms of performance and upkeep. There are a lot of other people around here with them, many of which are beginning to have the engines changed.
Nobody that I know has chosen a larger Honda for a 6.5 Camel boat and I have seen Yamaha, Evinrude and Mercury re-engines. The most succesful modification was done by a Guy called Tim who runs a charter company called Ribmaster in Portsmouth. He put a 200 v6 Merc on and took out the rear tank replacing it with a single seat. (giving 7 seats in all). It really goes and lets the hull prove itself.
when you are selling the engine don't forget they seem to be popular in Holland too.
