Prop Recommendation

[indyguy]

What prop would you guys recommend for a 120 VRO Johnson motor on a 17.5' Vanguard F/G boat. Currently have a 13.5x15 on it now. Seems fine but wondering if another pitch would be better.
Use it for pullin the kids around on water toys now mostly and some fishin time for me.

We always have ran 17" props for pulling, and 21" if your know you are going cruising. Not sure what the pitch was. But generally small=torque large=speed.

2 boats both outboards

110hp Evenrude V-hull 17'
135hp Mercury V-hull 17.5'

Try a 19 pitch prop, good all around.

What pitch are you running now? we dropped pitch size to get more "out of the hole" punch but then when we upped the HP it didn’t work, the prop cavitated bad. I would think a larger prop would give you more torque...more blade to water surface, smaller prop would be more opt to cavitate I would think!

I started out with a 19* 3 blade aluminum prop on my 200 Merc. It was terrible...cavitated out of the hole, and in sharp turns. I went with a 21* 5 blade stainless...that works awesome. Huge holeshot, no cavitation at all, but it would pull 6300 rpm with the trim all the way down. I found a used 26* 5 blade stainless...trimmed up top rpm was 5700, but it got a little spooky on the top end...around 75mph. The stainless steel props are expensive, but more than worth it.

You need to figure some things out. This is a good place to start.

Call ACME props. They guarantee fitment. As long as you do not nick it up they will replace it with another size until your happy.
