My boat is the poker run edition it factory tested at 90.3 mph. I have not made any hard runs this summer but saw 87 last fall at Lake Cumberland (poker run weekend) with 3/4 tank of fuel and 4 people on board.

mwdill what top speed and power do you have?
Steve

500 efi's, depending on conditions here at SML at about 900 ft alt 82-83, down at sea level in salt water i have seen 85 but had some extra weight in the bow

mwdill
Did you notice any difference in handling going from the 4 blades to the 5 blades (bow lift stern lift chine walk)
Thanks Steve

better handling, more bow lift, faster excel.
no chine walk
