AS 170 Propeller?
« on: September 20, 2009, 08:19:22 AM »
I am looking for a prop for my 170.  I am looking for info on what pitch and brand most everyone uses.  I will be running a jackplate.  So I am thinking of getting a four blade with lots of cup.  I am going to run a 1992 90hp evinrude.  I am looking for a good hole shot with a decent top end.  Anyone have any info on what they run?

Here's my setup:

1977 170 Aquasport
2007 90 Hp Evinrude E-Tec
17" Stiletto Advantage II Prop

I run around 5400 rpms with 2 people and 20 gallons of fuel. The hole shot is awesome but that's due in part because of the E-Tec. My top end is 39 mph on GPS.

Propping a boat can be a science. You're going to want to make sure your RPMs are as close to 5500 as possible based on your average conditions. Considering you're going to be running a jackplate, try and find a marina or dealer that will allow you try different prop setups until you find the right one. You may pay a little more for "one" ideal prop but it might be less costly than buying 2 or 3 until you get right.
