What are you guys running on your 115’s for a SS prop? Had an experience this weekend with 4 full size adults in it and had a hard time getting up to plane. I’m guessing the Aluminum prop was flexing a lot. Getting about 35-36 out of the Aluminum prop with 1 or 2, But that was the 1st time I’ve had 4 in her and she didn’t like it…
Why a aluminum prop? Mine was a stainless prop painted black. Check yours, I’m thinking you have the same black prop I did.
im guessing it’s aluminum…No numbers or letters stamped in it anywhere. and the blades are a little dinged up like aluminum, And just the way it was acting …
Check with Dean I didn’t think they came with aluminum.
Or….maybe mine was aluminum instead of stainless.
Back in the day, they were painted black stainless from our dealership. Cant speak for the other dealers. Many possible variables however, but I would speculate a one size lower pitch # will overcome the heavier load.
I’ll try…Thanks. Stainless wouldnt flex like that would it have?
Maybe I have a different issue.
First off we need to know if its even close to being propped right. What is the RPM at WOT trimmed up? This would be with 2 people in the boat. Then what size and pitch is the prop you have on now? Answer these simple questions and win the prop prize. LOL Turning Point Props has a Prop finder on there web site, believe Mercury has one also.
6000 RPM at WOT.
14″-17PITCH PROP
following
4 blade props give you lots take off torque. You said your at 6000 RPM at WOT so your propped right with what you have now. A 20′ fiberglass boat is kind of heavy for a 115hp to begin with.
