Prop suggestions

[Levie17]

Just re-powered my 2002 Trophy 1903 (2880 pounds) with a 2018 Merc 150 4 stroke. The new engine came with a 14 pitch pontoon prop so I'm not sure what would be a good prop for overall performance.

Thanks

Try the Mercury prop selector. Probably want something around a 17P.

Read the adjacent post: "Prop change caused a HUGE change in rpms" for some comments that can affect your decision. Some stats on your current operating conditions/engine ratings would help, like hard RPM/MPH numbers, time to plane out, trim responses.
