I've got a 235 Force 330HP 454/Alpha 1 1.32R. She is spinning a 19P Chopper that is less than perfect, to 4600rpm whether there is 2 people on board or 6. With 2 people full of fuel, best is 51. With 6 people 3/4 fuel best of 47. so 19% and 25% respectively. Rumor has it these boats are bow heavy even with a big block due to the bigger cockpit. Should I try a standard 19P dog ear prop with more blade surface? I'd like to get to maybe 15% slip? I think the alpha will still be plenty safe with those slip numbers... Or should I shoot to get even less slip? No trim tabs. 22 degree hull

I would put a 19p Turbo on that set up!!! I had the same engine and drive on my 87 265 and I had a 19Turbo and it was perfect and I tried them all... My boat ran about 57 on the dream o meter and 54 gps and it carried the bow just fine, I would think on your 235 the #'s would be better than what I was seeing!!

Very cool. I think I'm down on power, but even 55 would be great! I will start looking for one
