Found a used Yamaha 115hp it’s mounted on a boat. It’s a 2001 model. Last time ran was around 3 months ago. Guy is telling me we can bust it off in the water. Any input on these motors. Are they good? I’m wanting to take my mercury 115 off my boat and put this one. How hard would that be. It being two different brands?

What are you rigging it on? Makes a difference.
You’ll have to change harness and control cables. Maybe control box if you’re using a merc box.

I have a 2005 Yamaha 115 4 stroke. Best motor I’ve every owned. I’d pay a shop $500 to do that, and you won’t have to spend much more than that upkeeping it. Make sure the compression is checked and have a shop check out the motor.
Good luck,
Tim

We can do that for you and get a harness to switch from merc to Yamaha
