x2 if I could buy 10 mph for 20k I would be first in line.

I agree with gofastlvr, the other big plus to me is that you picked up 5MPH at your cruise speed. I will settle for more cruise efficiency anytime over top speed. Unless you intend on doing SPEED RUN'S for GLORY.

I also boat on Lake St.Clair, Trust me with a 42 Fountain that will run 75 Plus MPH You won't get passed too often. Many faster boats cannot handle the weekend water that Lake St.Clair is noted for.

I have to agree with the $1000. for a mile an hour increase being a good deal. I was hoping for more since the 28" four blades are on the rev limiter. I wonder what 30" four blades will do for her. I also am a little worried about my bravo 1 drives with the five blades. I love Lake St. Clair.

Have had 6 blade Herrings for 4 years no trouble.

What year do you have ? I have a 98 big step with side by side 500hps with labed 28 bravo I and i see right at 80 (79.9) on GPS with light fuel and 5300rpm
