Brad at bblades has been helping me figure out my prop slip situation. Started with a 30p B1, had 26% slip went to a 29p hydro P5 5 blade. Still at 20% slip. Im already running a 1" drive spacer. X dim is 5 1/2". My boat prop torques to the left pretty noticable. (Leans to the left). Brad wants me to run 2" of spacer. I beleave that will make my boat torque. To the left even more so. Thay just sent me a 28p 15 5/8" diameter mercury maximus 5 blade. Ill be testing with it tomorrow in hopes that it gets my slip % down in the mid teens and hopefully my top end up to 80. If i do have to go with more spacer will it get my lean on more than it already does.

i think the 1 inch spacer will help with the slip...but what do i know?...keep us posted,josh

smaller diameter will give you less twist on the boat..do you have a low water pick up??also you should be runninf a rt hand prop not a lefty,,that is probablt where the torque lean is coming from..espicially if your steering wheel is on the rt side..also put a straight edge on the last 8' of the hull and look for a hook..

Im already running a 1" spacer. Thay want me to add another inch to it. And i didnt know you could change the direction the prop spins. Mine is standard like every boat ive had. If your standing behind the boat the prop spins clockwise. Ive never seen any different on a single engine boat.

Maybe Transom/Stringes have some waterlog issues? Will produce Slip.

no waterlog issues here buddy. this boat is like new and in perfect condition. it never sits in water overnight and is garage kept at all times. Just got back from testing that new prop. thay can have it back. lost 6 MPH and was only turning 4600 rpm. guess thats one way to get my slip down. LMFAO!!! crazy thing is it blows out at 3500 and then bites back in when the front end falls on plane. I def liked the Hydromotive P5 better.

What rpm and speed were you running with the hydro?

5000 and 73. Thies are all GPS speeds not the wishometer. If i could get the hydro to hook up id be pushing 80.

It seems like you would want a smaller OD prop with more blade surface area. Keep us updated on the search, im still trying to find the right setup for my SCS.

I agree. maybe i should try the 6 blade herring thay have. 2 grand. #@$%!!!
