A high five is a good prop for getting on plane, thats it. What prop you need has alot to do with how you plan to use the boat. I like the large diameter mirage type props for most uses myself. Not the fastest, but good holeshot, faster cruise speeds, and good economy because of excellent bite.

To finish Ferm's thought I use a 3 blade Mirage copy made by Quicksilver without the PVS (vent holes) 21 Pitch. Not the fastest but great all around performance. Big round eared blades with some cup on the trailing edge for extra bite. Good bow lift, good cruise, both speed and mileage wise.
I had an EFI once. Sold it to a guy on here. Those motors drink lots of petrol...
It was the fastest motor I ever tried on my V-20 at 61.7 mph officially turning a 23p Tempest to the limiter at 5800 RPM.. Lots of prop slip but the stern lifts a little more with the Tempest and that prop likes trim. See signature picture of the 250 EFI strung out on the Suwannee River a few years back. That was when I weighed 270 lbs. Now that I am 175 lbs. I am sure I could reach 62 ;-) :beer:
Click on the picture to see how much boat is actually out of the water. The keel is touching water just in front of the console. Aired out for a old F-20 fisherman.Attachment 6316

The top slows it down.

Thats because you need to put some wings on it to increase lift, then it would help you out on the top end.

Wings impede fishing. Not that I ever fish. LOL!

Make them fold up into outriggers, problem solved.

Ridge every time I see pics of your boat runnin like that it make me want to hurry up and get mine buttoned up and out on the water!!!

:sun:Hurry up! What is taking so :cen: long? LOL! Pimping aint easy.

Just been lacking some motivation but hopefully will be testing it out the weekend after thanksgiving!

my 91 v20 is running a 300hp mpi small block with a bravo leg in mine.
i turn a 18" mariage plus prop and my WOT is 5200
really stern heavy and had to put tabs on it to stop it from porposing

its a heavy boat with all the downriggers, radar arch/rod holders, 6" full canvas top, stereo, 9.9 kicker, dual batterys, prawn puller with traps etc etc etc

my max speed is around 42 knots, but cruises ar 30knots at 3200 rpm getting 2.5mpg according to the smartcraft gauges. jumps up on a plane in 2-3 seconds. i could have saved some weight and probably gained top end with an alpha leg but found a complete bravo package instead
