V20 with the 4 cylinder I/O

[yodaddy]

I have an '83 V20 Cuddy with the same motor. Turning a 15x17 prop and get about 35 mph on GPS @ 4000 rpm WOT with a heavy load on (3 men, full tank of fuel, and 30 gal livewell). I'm going to drop another inch of pitch to get into the 4200-4600 WOT band. Will end up with a top end of 33-35 mph. I installed a Faria fuel flow meter and it looks like the sweet spot for cruising is about 24 mph @ 3000 rpm, getting 3.5 mpg. Trim tabs do help getting on plane faster, and are essential for any rough water / offshore running.

Will it need trim tabs to get on plane quickly? What pitch prop (average loaded) and what kind of cruise/WOT speed?

thanks
