Low teen's on the prop slip. Impressive. Stock bravo I 32P?

You had the motors dynoed, what was the peak HP rpm? Did it carry that number or did the HP number drop off rapidly?

14% to 8% with no change other then the lower unit. Same props turning the same direction. Picked up 8 mph turning the motors at the same rpm. Some of this I suspect is because the boat frees up at around 97-98 mph and I was just under that prior to changing the lowers. Once it breaks free the additional speed came quick. Any additiona speed probably won't come as easy.

tssteph, what prop are you running & have you tried a B1 with the diffuser ring cut off?

BTW, how did your paint job turn out??

That's incredible! How short are the shorties? I'm assuming our drives were originally in about the same place 1 1/4" below the pad?

I believe his drives were hanging a bit lower, mine are 2 1/2 below the bottom, (tssteph added -2 lowers) , that will be my next mod.

With the 2 inch shorties I am about 1/4 inch below the bottom directly in front of the prop shaft. Measurement was taken with the trim in the neutral position (straight with the bottom).

This has been on my mind all day so I went to the barn and measured it out. It is about 2 1/2 below the pad. I'm amazed at the increase of efficiency. Although my boat is for sale im must say I'm tempted..... I'll also bet the roost is a bit more showy as well with the shorties.
