RE: nh hull repair question
Ok , on an ABS hull ( I believe the HAMMER is ABS , if not , then simply fill in the crack - lift and fill , then sand smooth ) , plain resin ( like from an auto store ) will eventually "break" free due to the vibrations .
your best bet is to as I just wrote in another thread to a fellow who is having stuffing tube problems .
here is a link .... the stuff can be obtained from any auto parts store and costs around $6.00

More than likely you have a form of resin epoxy ( off white hard stuff ) holding in the stuffing tube . This is a REAL mother to remove . Best bet its to forget the heat , and try using your Dremel with a VERY small carbon round chewing bit ( I call them "chewers" cause they eat the metal/plastic, etc ,away ) then simply replace with an epoxy that they sell at auto stores which is used specifically for plastic tanks ( like the ones on some radiators , the washer fluid tank , etc , etc ) Once that stuff bonds ( and it DOES bond EXCELLENTLY ) , its there with NO leaks . It will usually come as a kit form , which will also include a swatch of glass matting , an alcohol swab , and the two part epoxy ... ( cost is around $6.00 )
regular glass resin will stick at first , but then the vibration will shake it free and you'll have leaks ....
Again , simply go with a flex shaft , and change the stuffing tube .... much better in the long run .
I did this to a WILDCAT which I put a Megatech M-16 engine in and got rid of the electrics . ( p.s. - this is the SAME stuff I used to hold the engine mount to the hull and she is STILL totally intact . )
