    F21 engine Height

    Just picked up my F21 from the dealer after they raised the engine (F150) to the highest mounting hole ( approved by Bayliner). Water tested today and anti-ventilation plate is still too far under water (approx. 2 Inches)
    I am working with my dealer to see if Bayliner will add a jackplate so new holes don't have to be drilled. Also the 19 pitch 4 blade spitfire won't allow the engine to turn over 4960 rpm ( per vessel view). I believe a 15-17 pitch prop will fix the rpm issue ( rated to turn 5800). 4960 is way too low Click image for larger version

    When I run my jack-plate higher I get better top-speed/RPM

    Max RPM under good conditions would be about 5400, hitting about 41/42 mph (GPS)

    Thats with the factory SS Merc Prop
