Fill a hole in a transom

[gazza2006au]

You may be able to bodge this abit take this however u wish its just a thought

For the moisture to escape u would need an opening or several at the top than u can place a heater on low blowing on the transom for a couple of weeks, the heat would possibly warm the transom and let the water evaporate thru the top cap but that is just a guest

If it were me and i didnt want to do a transom rebuild i would drill big holes along the top cap of the transom and wildly sticky tape a 40watt heated pad to the transom they reack about 30-38c and just let it sit and bake over a few weeks

Plywood transoms using marine plywood are rated to be boil proof for 1 hour without delaminating boiling water is 100c your only heating this thing to max 40c

Why have you pressed the panic button?
Have you actually tested the transom to see if it is broken?
You know the routine - tilt the leg up as far as it goes, and bounce hard on the prop area.
Keep an eye on the area where the motor is bolted onto the transom.
If there is deflection of more than (say) 5mm, its cactus and time for a rebuild.
No movement - great! Nothing to do, except monitor it over the next few years. (the above test every 6 mts should be fine).
Something between 0 and 5mm - monitor every 3 months.

Hey Giddy up,

I haven't tested the transom now as the outboard is off, but there is definite moisture in the transom and it hasn't been on the water for around 9 months.

I drilled the holes to test for rot but from what I can see there isn't any, but there is for sure water in there and a stench I've never really smelt before but almost smelt like diesel or something. The bottom area of the transom had the most moisture in it.... Guess it has no where to go.

I now was just wondering how dry do the holes I drilled need to be before I can repair them, and it was suggested to me to pour in wood hardener to stiffen up the plywood in the transom and was just wondering how I best go about doing that also as the holes are on a vertical angles etc

The smell is from the laminating glue and water mixing, mould will only happen when more water gets in and self drains when excess water drains it sucks air in and it will go mouldy
