Prop for 115 2S on SF 20

[muddywater]

Yesterday I picked up a 72' SF and towed it 500 miles with a 4-cyl standard Toyota Tacoma. I don't recommend anyone else trying this, considering that I could smell my truck burning on the steep hills. I guess it was the clutch. It will be fine when I get it home where everything is flat as a pancake.

Anyway, the boat has an old 115 Mariner that supposedly only has 20 hours which might be true considering it still has paint on prop and lower unit and has not been started in 17 years. One blade on the prop is bent (aluminum prop). Before I go buy a new prop or get this one fixed I wanted to find out if it is the right size. It is a 17 pitch prop (dunno the dia. If you can decipher the serial, it appears to be 48 77344A-4 17P (not certain about that first number though). I would have guessed a 15 pitch prop on a 115 on a 20 SF, but I really dunno. Motor S/N is 5940375. Anybody have any information on this motor? Since it says Fond du Lac, Wis I guess this motor was produced after Merc bought Mariner but I don't know much else about it beside the obvious stuff.

Thanks
