[QUOTE="Pappy, post: 457219, member: 3278"] [size=5]Get a tach on it. I have run one Hell of a lot more boats than you will ever run and I cannot pinpoint RPM by ear. I believe that power pack has a 6100rpm limiter in it and you [u]can[/u] hear that when it kicks in. There are no less restrictive midsections ("Legs" as you called it). It is not a reed issue....how can reeds allow an engine to continue climbing in RPM without a boat speed increase? What you probably have is a propeller with torn up leading edges cavitating in the water and forcing air past the rest of the blades making the blades slip. Send the prop off or buy another prop. No easy way out of that. You are being given good information. Use it wisely. [/size] [/QUOTE]
