Well I saw a lot of airboats on Orange this weekend, but I didn't recognize anybody from on here.
I was riding with my friend on his green 13' Lazer with a 4 cyl Lycoming.
I think he broke a piston or the crank. We were cruising along and all the sudden, WHAM WHAM WHAM!!!!! He shut it off quick and we got towed in.
The engine will still crank and run and is not leaking anywhere, but it sure is noisey. Good thing his other boat is almost done.
