Help with prop choice

[hosejockey4506]

im running a valero YT with a 2.4 merc on it.

had a 24p chopper on it and would rev out the motor(7000+ rpm) at around 70 mph, i put a 4 blade 25 trophy on there today and ran 73.8on the gps and still had a little left in the motor i was running 6000-6200 rpm but i kept running out of smooth water. would i be better of with like a 26p 3 blade of some sort. i had the motor jacked up as far as i could before i would spin the prop and loose water pressure. the only reason i ask is it takes a while for me to get up to rpm with the 4 blade unless i over trim the boat then trim down once im running 60 + i would like to gain rpm a little quicker yet still get some more speed out of the boat. im a newbie at this so any help is good.

You should also be asking about eninge height do do bird.

Seems he has about 4-6 inches of setback (jackplate). The propshaft appears to be about an inch above the bottom of the pad.

Get some measurements......
