2005 50hp Yamaha on Crest Pontoon

[Lawdawg69]

I have this really nice Pontoon boat with a Yamaha 50hp motor on it. Or rather my wife does, I have a bass boat. The boat is not real fast and not sure if it will pull grandkids on a big tube or something like that. I have inspected the prop several times and there are no numbers stamped on it any where. I am just curious if any body has any suggestion as to prop size or pitch that would work best. I have had a couple of people tell me I can put a bigger prop on the motor as long as it doesn't hit the fin above the prop.

First and foremost, you must know what the pitch on the prop you have is before you can make a guess as to the one you may or may not need.
Take it to a prop shop and they can gauge it, then you can ask them for a recomendation and make good choice.
