Thanks Farmer Grant
The merc website describes it as an assembly and the list price is $400 more that the 4 blade. Are there additional components (new shaft since it appears longer) or is it just a high $ option?
Unfortunately I just put a new 4 blade & wear ring in a few weeks back! But due to my driving habits (go till ya get stuck) I'll be getting a new one every season. |

Yes, we do rebuild our old impellers. The impeller we're talking about is a new design for this pump. Better hookup in the bottom end, less cavitation in white water, and longer life when pumping gravel. |

What change in RPM's did you get with this new impellor?
What about top end speed?
Does it fit all right as it seems longer?
Cheers

I heard -250 RPM at WOT, and you loose 1 to 2 mph. I believe that was on the 240. |

It had the standard impeller for the 240hp. WOT is down on speed, haven't checked speed with GPS yet. Maybe 1-3mph? RPM down at WOT 100-200 revs. Cavitation GONE! _________________ WHAT ROCK ! |
