Sorry for bein a rookie but is there a certain rule of thumb for boat size, engine, and prop pitch/blade? I'm with rex on this one, I would hate to have to put all of my stuff in the cabin and have my buddy stand on the bow just to take off everytime.

I had a 22 Scarab with a 7.4L. It had a hard time getting out of the hole. We wanted to ski with it. I found that a 4-blade Bravo worked the best from the props I tried, but I didn't get to try any Hydromotives. I put tabs on, and feel it wasn't worth the money. The bb makes them real tail heavy. I used a 22 Bravo which was a little small but it got on plane faster and the boat worked better except for top end,the 25 Mirage was better. Doug

You would probably benefit with a 4 blade to get a better bite. With a load in the boat (and center gas tank full), your prop is most likely slipping too much. The 3 blades run good, and flat, at WOT, but don't get enough grab out of the hole. I'd suggest a Bravo 22-24 pitch (4 blade).

Time to plane and top speed are arch enemies, only way you get both is MORE power. I had an 18 ft with 260hp. With the speed prop I could hit 64 or so, but could not get it on plane with four fatties on the back seat. I mean it would NOT plane no matter how long you held it with the drive all the way in. Put the ski prop on and you could not put enough people or skiers behind it to hold it down, top speed 50 mph.
Installed a 450 HP 406CI small block, Bigger prop and pitch, 75mph, and load it up and you could not tell anyone was in the boat! Was fun until it spit teeth out of the side of the alpha drive one Sunday. New drive, smaller cam, sold boat, went bigger.
