Prop's performance & trim tabs - need help

[Old'sCool]

Peter, My old boat ('90 22' Whaler OR) w/225 Yam. 2S and Bennett 120's. I went from the Yam. 19" 3Bl. to a Solas 17" 4Bl. I didn't have the weight issue you have. There was better holeshot, not quite the top end, but could stay on plane at a MUCH lower speed. That was my goal as that hull didn't ride too good fast in rougher water. I know all the "experts" will project what will be the end result but, if a local dealer worth their salt will let you try multiple props and document the changes/differences in return for a sale of two props is what you need.
