Water testing new to me 115 HO Etec, and Prop size.

[Workboating]

I know about water testing prop and RPMs. My question is. I had a 115 etec (2007) on my boat, I just repowered with a 115 HO etec (2019) Will the prop from the old motor ( Pitch/size) work on the new Motor. And If I change the prop out on the motor, will the computer need to be adjusted of is it all RPM like the old engine.

Prop should fit and then enjoy the newer motor.

Agreed. Same boat....same prop as long as it fits the engine.

The "HO" doesn't mean much.

Totally 2 different engines. The 2009 was a 60° looper design and the 2019 is the 3 cylinder G2 series. It should have the V6 diameter lower unit and will likey require a prop exchange, Now depending on what you are installing it on as performance hull will likely need to go up a pitch. A toon, CC or runabout same pitch prop should work fine. Just be aware there is no support and parts for the G2 motors. A customer we know has been waiting a year for a wiring harness, only to have it installed and motor threw a rod first trip out. He took a $20k loss and bought a Merc .

I didn't think it was a g2....are you sure?

I have the g1 115 and it has the 6 cylinder foot.

My brother has a g1 ho and the only thing I saw was water pickup is different and a few other things.

I was also told in the g2 you could get the 3 cylinder and the 6....6 had more torque.
