Actual versus Fountain test sheet
#1
Wanted to stay amongst friends with this one to avoid any Fountain / cig ot comparisons 
35 Lightning, twin 500's, XR's, Bravo 30's, inward rotation. We match spec sheet pretty darn close until wot.
Fountain - Drives - 4.5 / Tabs - 2 / RPM 5300 / speed 86
Actual - Drives 4.5 to 5 / Tabs - 2 / RPM 5100 / speed 82
I assume Fountain is running driver only with probably 10gal per side. Our run was with my honey on board and 1/2 tank fuel, 83 deg and flat lake water.
Is it going to take some rough to see 5300 because the sticks are jammed. What do you guys think, are we where we should be?

less fuel, salt water and one less person..... but if Reggie was driving add weight for jewelry

My 04 29 Fever was exactly the same as the test sheet...I boat in salt water and simulated the same conditions...myself, 50 gallons of fuel and found the tab and trim settings were exact to duplicate the speed that the Fountain driver got on his run.

The Fuel could be the difference too...
40 Gals per side is 80 Gals X 7lbs/gal = 560lbs.
Also, the test sheet will show conditions. If the river water was colder...would also make a difference. Have owned a 29 Single and 35 Lightning and both performance reports were on the money.
Had a buddy with a used 35 twin step that had a similar divergence from the performance report. The boat had different props from the report.
Gotta get that 200 RPM back. Good Luck.
