Am I going to buy the right prop.

[ghostrecon3]

I have a 1991 Four Winns 170 freedom bow rider I/O with a 3.0Litre OMC. I have done alot of research on the subject thus far but before I make a decision I wanted someone to confirm that this is the correct prop for this boat. I was told by four winns that my prop would be a 14 1/2 x 19 for optimal performance. I do not plan on doing much more then pulling a tube around the lake and pleasure cruising. Obviously not a race boat so I could care less on that aspect. The prop appears to have a nut and cotter pin attaching it to the shaft. The sticker on the lower unit says Cobra alone. I couldnt begin to know how many splines it is or any of that, but from what I think someone saying that 1991 was the model 800 which is a 15 spline but dont quote me on that info. Hoping for someone to help with more knowledge then myself please. Here is the one prop I have thought may be the correct one. Also if it is the right prop is it necessary to buy the prop kit new washers etc or should the old ones be fine unless they show signifigant signs of wear? Will the nut warp when its removed and you might as well buy a new nut with the order? Anyhow heres the link to the prop I believe it might be: Solas Amita Aluminum Boat Propeller #2511-145-19 for OMC - Outboard Marine Sterndrive Model 800, Cobra & King Cobra 3.0L 1991 - 1994 Any HP - iboats

Re: Am I going to buy the right prop.

Your application does come up as you have indicated, however you should answer the Qs in the stickys at the top of the prop forum.
At 22 years old and depending on your typical load and activities your selection may be different.
Your present prop size (usually near the base of the blades)and wot rpm and speed lightly loaded will tell us if the 19" is appropriate.
