Hello everyone, this is my first post and of course its a prop sizing question. I have been trolling this forum as a guest to try and find an answer and have come close, but need some reassurance.
First off my motor is a 85' 70hp johnson and my boat is an 88' lowe pontoon. I really want to change the prop since the ends of two of the blades are chipped off. My problem is I cant find the pitch number on the prop anywhere. I think its in too bad of shape and has worn off. My second problem is I dont have a tach, so I cant say what rpm im running at.
However through my searching on here, I have come across a few older post with setups similar to mine. Most seemed to be going with a 3 blade 13.75 x 13.
Does this seem about right? Thanks for any input and this forum is great. I have picked up a lot of information just searching as a guest. Glad to be a member now.
