I have inherited a 1986 lund predator, it runs great and works wonderful but when i put more than 2 guys in it it wont plane out, the current prop is an aluminum 15 pitch and i feel as thats not correct(who knows if its been replaced) the motor is an 87 mercury 45hp classic 50 tiller with power tilt and trim. Is all i want to know is what was stock OEM on this boat from the factory? The internet is not helping me because i cant seem to find anything out there. Any help you guys can provide would be wonderful, the knowledge and stuff ive already read on thing has helped alot!! Thanks in advance and tight lines to everyone!
