BOAT & MOTOR DATA TO CHOOSE BEST PROPELLER
1983 Crest II Pontoon Boat Model 25, Load: 2400 lbs., Max HP: 85
Pontoons 24? long X 8? wide, Circumference: 61?, Diameter:20?
Aluminum Deck installed August 2011, Aluminum Ski/Tubing platform installed
Total boat weight: 2060 lbs.
1995 Mercury Bigfoot 60HP Purchased and installed September 2011 (Compression
is 127, 125 and 119 lbs.)
Purchased and installed HS CMC Hydraulic Jackplate PL-65
Purchased and installed Mercury Spitfire 4-Blade Aluminum Pontoon
Propeller 13.8 x 13P (488M8026570)
Initial adjustment of carbs was performed with boat secured to trailer in water
using tach on each plug wire as I adjusted the corresponding carb.
Test Run with 1/2 tank of gasoline and usual load. The outboard ran best with
Jackplate approximately 1-2? above the lowest setting. The speed and RPMs were
the same going downstream against the wind as they were going upstream with the
Wind. The readings I got was 7 MPH top speed (Phone App) and 2350-2400 RPMs.
I want to find a propeller (Maybe an adjustable pitch) to get my best tubing speed
(with 2-3 tubes) and RPMs between 5000-5500.
Thank you for any assistance you can provide.
