250 E-tec prop?

[A.Hoj]

I have a new 250 e-tec on my 23' grady white gulfstream, and I am wondering if anyone knows which prop would be the right one. Right now I've got a 3 blade ss Rebel 14 1/2" x 21" I believe. possibly 19" pitch though. I'm only getting 4900 rpms at full throttle and 34mph. this seems way off to me. From the research I've done I think I should be getting at about 41mph @ 5500 rpm. but I can't find any good info on which prop will work best.

Howdy, and welcome to iboats.<br /><br />Why would you even consider messing with it when it's under warranty? If you are only getting those RPMS, there is something wrong either with the motor, setup, or prop selection. Could be a combinationn of the three. Either way, sounds like the dealer needs a call.

A.Hoj, the dealer needs to know about this ASAP if they set it up...<br />I'd expect to see a Cyclone or Viper on that rig from a dealer.

Definitely work on the dealer until that is resolved. Kenny is definitely someone you should listen to. You have come to the right place for help. Keep us posted to the outcome.
