Re: Transom Broke off Suntracker Pontoon
I'd start by crying, then picking up the pieces. Sorry.
Looks like the fasteners failed and the engine mount just fell off.
Be thankful this didn't happen while the boat was still in the water, or on the highway at 60mph.
Inspect everything from framing to welds and fasteners, looking for cracks and corrosion.
Then its time to correct any defects you find, using materials a bit more suitable to the saltwater environment, perhaps replace the mount with a fiberglass mount..
Rebuild at twice the structural integrity.
I never liked the way the mounts were bolted to the bottom of the deck framing.
I would rather see the mount flanges on top of the framing so the weigh rests on the flange, instead of hanging from a bolt.
