I have a 70 18hp evinrude on a 69 richline 14ft aluminum v. I bought the boat last year and finally got it all redone and running properly, thanks to great advice from the iboats forums. So now that it actually has some torque, my prop is slipping and Im going to replace it. I was hoping for some advice on what size to get. I dont know the top end rpm because as soon as i got it running good the prop started slipping. As far as i can tell the motor normally came with a 10x9 prop with a 9x9 as an option. Mine was the 9x9. Should i keep the 9x9 or go to the 10x9? We normally only have 2 people in the boat and light gear. I would consider it very lightly loaded. Any advice would be appreciated, thanks.
