I was going WOT, after crusing at about 3.5 mph for 30 mins, and all of a sudden i lost power. It felt exactly like it did when my other 115 blew, 4 years earlier. So i slowed it down, hoping to limp back to the landing to pull it out of the water at least.
It siezed as soon as i cut back on the throtle. So after 2 hours of drifting, someone finally realized i wasn't waving and towed me back in. Upon reaching my house, i pulled both heads off. The starboard side was okay, which gave me some comfort because when i got the motor someone had stripped out a spark plug and i rethreaded it, worked fine. But thats also the side that blew on my old 115. So, i go to the port side, and pulled head. I can right away that the lower piston on the port side is done. There were tiny shavings in there, and the cylinder walls were completely dry and rusty, with some water in there. The cylinder wall doesn't appear to be scratched, but im sure it is. There was a little chunk off the piston that seemed to get smashed up in there. I think a connecting rod broke, because it seems to be a little twisted, and not in line with the one above it. Now, i had an extra set of pistons and a head for that side from my old motor, if the walls aren't scratched would it be worth trying to get it to run again? Also, what could have caused that? it doesn't seem like a ring issue like i had before, but that fuel wasn't getting to it or that water had gotten inside.
I was having problems a few days ago, and summed it up to be water in the gas, and after draining the tank and emptying the carbs i went back out and had no problems except for a little spot of hitting the bottom, and then it cut out for a stroke at WOT but resumed and was perfectly fine.
This motor was sitting for 4 years before i aquired it, so i really don't know if this was a problem before i got it, or if just happened.
I'll post up pics when i get a chance.
