[QUOTE="Pappy, post: 493355, member: 3278"] [B]If you are using the new pump as an example of that you would be incorrect. The newer engine is 56 CI vs the 1979 version at 49 CI. Bigger engine and propshaft rated horsepower. More laws on the waterways as well and more "No Wake" zones. We started seeing issues with the larger engine mainly on pontoon or similar boats and mainly in the NW zones. When these engines were lugged or sometimes propped incorrectly they would see a high throttle angle, high timing, and low RPM or what you would see while trying to fudge a bit in a NW zone. Combine this with a few other factors and we started seeing #2 cylinder failures. The new pump and pressure relief setting was developed to reduce these failures. The engine was still a pretty good design. Both versions loved RPM and really shined when propped up in the top of the band or beyond. [/B] [/QUOTE]
