What prop size?

[KevinCarey]

I have a 2 stroke 25hp mercury on a 1436. What prop will make me go the fastest?

Re: What prop size?

You have to give more info if you want good advice. Year of motor, RPM's with current prop, current prop specs, and GPS readings would be a good start

To do this accurately we need the present prop size(under the prop nut or near the base of the blades)
wot rpm and speed. An induction tach is easy to hook up and some cells have a gps app.
Also need year of motor.

Assuming that is a Lowe 1436, the Mercury prop selector comes up with a Vengeance SS 10.38 X13" pitch. I believe that is the "biggest" pitch prop Merc makes for that motor.

I know they make props for 2 stroke merc 25hp at least as big as a 10.125X15 not to say he can turn it at recommended RPM's though. Got no info to go off of.

That thing is going to fly!

(I have a 7.5HP Force on a 1436 Tracker and it goes very well, low to mid 20's depending on load.)
