Thank you for your reply, i have a 2 tube pontoon, the yamaha motor and prop came of a hurricane deck boat which we scrapped out and installed on my current pontoon which we rebuilt.
I have a 24 ft pontoon with a Yamaha 115, 2 stroke. I am looking to purchase a new prop because current one overheats the motor, it was originally on a deck boat. Any good websites to use for picking props??
