2773 + SV23 = Win

My wife damaged our spare and we upgraded.  The 1939 we had on the boat was fine.  With the addition of the FAE, I went from a top speed of high 46MPH to high 41MPH last year.  Still had plenty of power, but once we added a surf device and weighted the boat more evenly, I felt a little more power wouldn't be bad.

In comes the Acme 2773.  15x13, .105.  The results are excellent.

At 10.5MPH, I dropped 200RPM, even though this is a more aggressive prop.  I was using less throttle too, so fuel consumption will go down for sure.

Top speed increased by .5MPH...bonus.  I think this is due to it allowing the motor to rev out better...still had another 150RPM before the 5800RPM rev limiter.  Not sure how it would react on the non-LS1 motors that have a much lower RPM limit.

Big hit on cruising RPM.  I never logged what the 1939 was, but it is a good 400-500RPM higher across the board after 20MPH.

On big lakes (once a year, tops), I will switch back to the 1939 for fuel economy.  Otherwise this prop is staying - it performed very well.  I think it helped lengthen my wake a bit too when surfing.

My weight setup:

- 900lbs in each rear locker
- 300lbs under the port seat
- 500 in the ski locker
- 300 in the bow
- 100 lead in the front bow walkway under the filler cushion
- 100 lead under the very rear starboard seat, another 100 lead under the very back of the port seat, between where the rear locker and port seat bags meet
- Floating wedge
- Faux-nix Eight.3 Wakeshaper (same as the Ronix but a rip off design)
- Minimal crew, buddy driving, wife and my 5 year old
- Custom surf flap to fix the severe spray issue on the top of the wave caused by the FAE.  No exposed bags anywhere.

I thought the FAE was inefficient but I didn't think I would kill that much power.

I believe the MEFI puts out a Gallon per Hour message, it would be interesting to monitor this to see if the fuel consumption did indeed go down.

I think restriction + additional drag is what killed my top end.  My ECU is the CEFI-3...not sure if that logs fuel consumption, but I doubt it.

The have to CEFI 3 also, it's the same as a MEFI 3.  Ingmar's'  documentation shows a GPH fuel consumption message, but I don't have a tool to read it.
