I did talk to brett at bblades, we did talk about drive showers...he instructed me to cut/shorten the pick-ups under the cav plate. Mine are like 1"- 1 1/4" long, he said they shouldn't be no longer than 1/2" long. I cut them down yesterday and we are gonna take her out 2morrow and see if this makes a difference, if not, im gonna see what engine is doing it the most, exact w.o.t. speed and send him the props to have reworked. He talked about doing some things to increase top speed and w.o.t. with adjusting cup on blades...we'll see what happens?

Good point, never really thought about pickup placement, I looked at mine and found the starboard is on the upstroke of prop, the port is mounted on the DOWN stroke of the prop????? I have the solid line cooler that follows the contour of the drive, if i put it on the other side, the bend at the top will be the wrong way??? Im gonna pay close attention to this, I may have just found the culprit!! I will post results..
