Hole Shot Blowout

[Bassmagician]

I own a Sprint 290 DC PRO, it's 18.5' long, weighs 1200 lbs. with a merc. 150 XR6 and a 10" jack plate, 1.75" to 2" below the pad. I recently broke a blade off of my 23 pitch Power Tech 3 blade 13.75 dia. I have replaced it with a Turbo TXP04 23 pitch 4 blade. It is almost an 1" larger in dia. I picked up a lot of speed on top end 5800 RPMs WOT, but I blow out on the hole shot & turn 5000 RPMs or more if I hold it to the floor. I have been having to feather the throttle arround 4000 to 4500 RPMs to get on plane. I have read that the motor setting may be too high and the prop is catching air. Would it be a good idea to lower the motor? If so how far?

Ok what u have been told is true. Each and every prop has a sweet spot.....or I should say each and every prop,motor and hull combination has a sweet spot. You can line up 10 boats......same make,motr and prop..and you stand a VERY good chance of each one being a little different.....Its the nature of the beast. A prop from the factory is no where true and balanced out. Yes I know it seems futile to spend 4 or 500 on a new blade and then spend another 125-200 on it to get it Balanced and blueprinted. I have seen as much as 3 different pitches on one prop. Sorry for being long winded but I beleive everyone needs a little back ground info. So to answer your question and explain why.....yes the prop is bigger and has nmore blade area.......being bigger at your present motor height is alowing you to cavitate when nailing the throttle because more of the wheel is outta the water AND with more blade area will acentuate this problem. You aint far from being where you want to be. Start to drop your plate in small increments. I wouldnt go more than 1/4" at a time till you regain your holeshot. With the numbers you gave me you should blast outta the hole and run to the topend like a jack rabbit. AGAIN you arnt far from where u need to be so small moves are the key right now.

Thanks a bunch 1FASTLASER, I am off today and I will try moving the motor down untill I reach Bassboatopia. I'll let you know how it goes.

I got out today had to lower the motor 1/2" and that done the trick. I have to ease into the gas but once it reaches 3000 RPMs I can punch it and it jumps out of the hole. It also does better at midrange, will stay on the pad at a little less than 4000 RPMs.Thank you very much 1fast, I'm back to grippin' and rippin' again. YEE HAA!!!!!

I am going to buy a new 09 MIM P-bass and I really like the looks of the gold pickgaurds that are on the 57 RI, but they are 10-holes. I would like to put a gold pickgaurd on the MIM p-bass but that is a 13 hole pickgaurd. Will it still work or not?

I think you have the wrong forum.The 10 hole will work but you'll probably have to put a couple new holes in the body as the 13 hole screw holes won't line up. The old holes will be covered so go for it.
