| Post subject: | Prop work, another question |
I tried a 27 Hoss copy on my Baja (thanks Max). Too much pitch but it just rolled onto a plane with no drama. Then I tried a 26 small ear. Same top end but it pegged the rev limiter coming onto a plane. Is there anything I can have done to the small ear to help it plane? A whale tale of some sort would probably work, but I can't see putting holes in the new Etec. |

Oh lord please don't say the word whale tale lol. Some of the best wheels are the ones that barely plane  But if your top end is suffering likely a 26 cleaver of some sort would be on the money, need more wheels to try  Often even the best wheel you find still has to be sent away to tend to specific issues. Once you work the wheel you believe is your #1 than you're set! But its not just slap two on and good to go Lots of testing.

On my SS 2000, I have a Bob's True Tracker, and a lot of over hub props just roll onto a plane without drama. I get a bit of spin, but nothing crazy with a few others. My strategy with the Ally is not to work the best props. Don't fix what works. I had my second tier prop worked this spring though. On my Baja, a 23 SRX and the 27 Hoss copy planed easily. The small ear pegs the limiter. Practically for 1 mph, the bigger over hub props aren't worth the loss of acceleration compared to the 24 Laser I have. I'll give Kawartha props a ring about my planing issues with the one prop and see what they suggest. |

David - what are you trying to achieve - all out speed or overall performance? |

With the Baja/115 HO I've got a ski prop on that we use 99% of the time. I was trying to see how fast the boat would go with an over hub prop because it just seemed necessary. It would be nice to be able to get on a plane easier with the speed prop, but it's not vital. I think with a prop change and perhaps an engine height change, I can set up for speed or skiing. When I had a 100 I used the same engine height for both, but that might change with the new motor. |
