Re: Transom and decking checking
For the transom you can drill some test holes from the INSIDE and only go about3/4" in, use a stop collar on the bit to be sure you don't go too far. Use a tray or similar to catch all of the sawdust/filings that come off the bit, then take them and carefully inspect under good light(not down in the bilge). You want nice yellowish dry shavings, black dark brown and moist and you have problems and are most likely in need of a new transom. Make sure to get down by the drain plug in a few spots and around ANY bolt/outdrive/transducer etc holes through the transom. If all checks out okay clean all test holes and area surrounding and refill holes with some marine tex and you are done. The floor can be a bit more tricky if it isn't phisically soft anywhere it may be fine. If you want to go further try and see under from an access port in the floor(over gas tank) look as far as possible with flashlights and a mirror or in through a ski locker if equipped. Otherwise its rip up the carpet, skill saw up pieces and inspect that way...
