Prop question???
Interested in hearing some opinions, got a 13 3/8 X 17 stainless on my 19 ' skiff with a 90 hp ETEC. Wants to porpoise above 4200 rpms trimmed all the way down, plus I think the max rpms I've gotten is 5100 or so, too low below the max which is like 5500-5800 i think. I want to switch to a 4 blade stainless for stern lift and hopefully stop the porpoising, plus drop down in pitch to get the rpms up.
Thinking about a BRP Rogue, Solas HR4 Titan, or Solas HR4 Rubex, in either a 13 1/2 X 13, or 13 1/4 X 15, what y'all think? Plus if someone has one like what I'm looking for kicking around in good condition I'd be interested.

You may need to shim the motor.
My father had that problem with his 16V Ashcraft when he had the 90 horse on it. West Marine. http://www.westmarine.com/buy/t-h-ma...rctxoC47Dw_wcB Here is a set on ebay. http://www.ebay.com/itm/like/2719362...&ul_noapp=true

Those have crossed my mind, I'm running a TH Marine Atlas jack plate as well, and dont know if having too many "links in the chain" so to speak would be a bad thing?
