Do I need a different Thrust washer from a Bravo 1 prop to a Hydro prop?
I have a Bravo 1 LWP drive. Standard shaft--1999 model
I did get the spline coupler, but I started to think I need to change the thrust washer also?

I need to know for testing on Sunday

When I tried a hydromotive over my normal Bravo One prop I did need a different thrust washer otherwise I had about a 1/4" in & out play without the correct washer.

I Used The Same One For Both Props.no Play In Mine

32 caliber

used the same one here also, no play

The same thrust washer is used. The difference is in the castle nut. The Hydro's take the old style castle nut. It's only about 1" long compared to the 3 or 4" found in the flo-torque hubs.

Well, did not need a new thrust washer
Used the same along with teh new adapter

Am pleasantly impressed with the new props
7-9mph gain at 3,000
4-6 at top end
This is with 90 degree 70% humidity and not very long running distances.
What impressed me the most, was the trottle range I now have
Prior I would be out of speed at half throttle and at teh rev limits
Now I am still climbing and away from the rev by about 200
