My neighbor has a pontoon boat I believe he said it is 20 feet by 8 feet
with a force by mercury 75 H.P. outboard he is confused about what his size
and pitch his prop should be. Is there anything I'm missing as far as info
needed to determine this. Thanks for any input you guys out there might be
able to give us.
