Little update.
The used prop wound up being slightly bent, bent enough where it vibrated too much to even use. So after talking with the seller, I decided to get it refurbished and was refunded $50 (basically half what I paid). Took a week and the prop came back like brand new. I used Atlantis Prop out of Cinniminson, NJ. Guys are very professional.
The boat has been running great except at wide open throttle. I'm getting some pinging/rattleing. Not sure if it's the octane, carb or what. I've been running regular gas so I might try 93 next time and some octane booster. I did adjust the secondaries and on muffs can see them opening and \fuel dumping into the engine.
Anyway, pic from last time out....
