What Prop Do I Use?

[Keefbikes]

I Just bought a 89 115hp Mariner 25inch. I am putting it on my 89 19ft Cuddy Bayliner. I live in Utah so my elevation to each lake can change drasticly. What prop size and pitch is going to be the best for my boat? I fish alot but also do some water sports. I would rather be concervative and put less strain on the engine to make it last longer than get a faster speed. Can any one help? Also what is the best way to drain my fuel tank on the boat?

To drain the fuel tank, disconnect the fuel line at the engine and siphon it out. Just curious, isn't a 25-inch shaft a little long for that boat? Prop is a wild guess -- probably a 21 pitch. Someone with that setup will probably be along with a more accurate response.

Im not sure if that is to big for my boat, I believe my last Force was a 25". How do I measure the shaft Length? How do I siphon it with the snap on attachment on?
