Re: 1984 beachcraft.
.......Still researching what prop might be the best for good hole shot and cruising. Any suggestions would be very helpful.
Thanks

What is the prop that is on it now? That drive is probably a 1.5:1 ratio. If so, my 5.0 roller cam Ford, with the same ratio and in a 20ft boat, runs a 15 x 17. At that, I am slightly over propped as I can hit 5k rpm with a full load, at WOT.
Now my boat(that is my other boat, not my BeachCraft project) is bigger and may be a little heavier than yours. My motor probably has more poop than yours but yours has a higher hull speed than mine does.
I would guess that a 15 x 19 would suit you well, especially if you get the smart tabs. They will make a huge difference with a full load of players, especially when you are doing low speed sport activities and on any takeoff. With SmartTabs, with minimal load, that thing will absolutely leap straight up out of the water, with little or no bow rise.
But, I digress. I would run what you have and make a determination if you even need to make a change.
