Prop suggestions

Post by Eastward »

I have a 18’ Apache, fiberglass hull, with a 502 (450hp) and reduction gear (2.03-1). I’m running a 80” 8-blade Wrapdrive prop. The boat performs great but struggles to run dry. I want to switch to a prop better suited for dry ground. Suggestions please?

A wider blade should help you such as the Sensenich JW or JX, as would changing your gear ratio to a 2.3 or 2.5 in the process to leverage more power.

Going to a wider blade will take away the zippy feel and give more push for a large boat.

I would give Darrin a call and see if he has recently propped a power combination matching yours in the past and what worked best.

Your HP and RPM data needs to be accurate to get the best result.

Think you will need more hp to push a big boat like that. What rpm does your motor do now?
