Help! Prop compatibility.

[Mercnewguy]

I've found a steal of a deal on a prop and need to know if it will work for my boat. I posted about this the other day but this deal just came up and I need to let the guy know today whether or not I will buy it. The prop he is selling is a 13x19. I will be putting it on a 1982 ranger bass boat 18' with a 1973 Evinrude 135 hp. When I do the Overton prop finder it recommends 13.25 in the 19 pitch for the regular michigan match but says a 13x19 will work if I get the michigan vortex 3 large area. If I buy this 13x19 will it fit and function properly? How much difference will that 1/4 or 1/2 inch make?

Thanks!!!

Re: Help! Prop compatibility.

First of all what are you running now and what are the rpms at WOT? Next, the prop in question, is it the proper hub size for a V4 gearcase? A 13x19 could be also be smaller hubbed prop used on some 55, 60, 70 hp models. What make and part number?

Thanks for getting back to me Jimmbo. This motor is new to me but I think its about 5000 WOT. The part number stamped on the bottom looked like it said 390896. Its a 13 spline.

As far as I can tell it should fit
