Swamped the Airslot

[dizzyspots]

Thanks for all the replies, unfortunately, being in Baja, I didnt have access to most of that...and an early AM departure to return to the US for work resulted in me leaving it in a friends 2 car garage...in Baja. I wont get back there for 3 or 4 weeks.
1) The motor was tilted up..tried to start motor after re-floating off the beach the next morning...batteries weak..no joy...as I was being towed back to the estuary to put the boat on the trailer, I tried several times and got a start twice..on high idle...but nothing continuous. Ill pull the plugs and do the MM routine and drain carbs when I get it back
2) No running water for flushing anything before we left. I did open the bow hatch and the console flaps so it could air out
3) One saddle tank was near empty, the other near full...I plan on draining both upon return
4) There is NO access to back side of the sponson...I did use auto grade POLYESTER resin , not epoxy for initial repair was that wrong?
5) Nothing is happening until Oct 30-31 or Nov 7
6) Any concerns about the understructure (stringers. foam. transom) being flooded over night??

did your powerhead go under water?

The hull is nothing to worry about... The issues will be with anything metal

If you removed the gelcoat before doing the repair it MIGHT be ok but I suspect that you likely simply put a bandaid over the leak... To repair it you need to fair it at at least a 5-1 scope and layer in new glass... I/E if the glass to be repaired was 1/2" thick you would need to grind back at least 2 1/2" in all directions.

I would not use anything automotive grade anything and would much prefer epoxy.

The boat was not sunk..it took on a lot of water because of a gash in the outer sponson. The water was below the gunwales. the batteries and battery switch were submerged.
The engine was tilted fully up, the engine cover was touching the water, not sure if the carbs/powerhead got water or not.
The initial repair last season was 60gt prep to some raw glass but probably some 60gt gel. it was 3 layers: 1" wider all around, followed by 2" wider and 3" wider. Hardware store polyester resin and mat

Having saddle tanks your fuel is probably ok as long as no fittings or the fill or sending unit was submerged. One advantage of saddle tanks.

the vent and necks were above the water line...i'll suck a sample and take a peek....

Ok....motor is frozen. pulled the heads..found some corrosion is port lower cylinder...soaked with Marvel x 1 week...wont budge even with a socket and breaker bar on the flywheel not...tried electric impact as well...doesnt move.
Carb/intake look clean...gonna pull the intake and take a look at crank/bearings Ive built several auto v8's over the years, but not an outboard: 1987 Evinrude 140 looper..(200hrs) open to ideas and suggestions.....Mike
