Re: Banshee Boat transom problem
tested in water. running great. did lots of meneuvers at various speeds to see if it takes water under different situations. boat balancing well and very stable. took the water plug out and surprisingly, no water.
Just to recap: I used fir-ply marine plywood, 3/4 inch, two sheets. I glued both together using marine glue and used stainless steel screws to keep it tight in place. Did the fit-test and than fibre-glassed it all the way around twice. Its was rock hard. Fixed it inside the hull and used only fibre-glass to put it in place, again using wood screws with washers through the hull openings to keep rigid in place. it cooked well and I closed everything from inside using various kind of fibre cloth and resin. Than used 2lb/sq.ft closed cell two part foam to fill the back columns (older one was rotton. Covered the top of foam with fibre-glass and resin to stop any intaking of water. Than removed the temporary screws, closed all the old ones from outside and inside using short-strand fibre putty. sanded, putty in, sanded, putty in till smooth. I realized that due to the heavy 105hp chrysler motor and hauling, and due to the fact that the transom is smaller than most of the boats, I used an aluminium L-channel fixed on top of the transom right where the motor will sit, run from one corner to the other. Made new wholes, rented a engine hoist to pull-n-push the engine back in place. Made new holes, used 5200-24hr cure with the new bolts and U-channels, every thing well in place. As I mentioned, I found cutting out the upper hull from the sides where the width is the least was more feasible option. So I resealed the upper hull back. One problem though I found is that the lower and upper hull wont fit onto each other perfectly after the new transom as those were deshapped due to lots of pressure and rotton transom over a long period of time. So i decided to permanently seal-off the back upper hull to the lower one. So grinded off the joint, put a new wood inside the lower hull, joined upper and lower hulls, SS screws in place and than I fibre-glassed the entire joint to make sure it never takes any water. Sidings in place and used 5200 where needed. Also took out all the interior upholstry other than seats and used venyl sheets to reshape the interior. Good shape, results satisfactory, no water taking in, no balance problems. Now it guess its stronger than before. The only thing is, if the transom fails in future, the boat has to be discarded as it will take long long time to cutout the upper and lower hulls.
Thanks for all the help I got on this forum. And yes I did learn a lot about the engine as well as I messedup the wirings at the ignition and the engine wasn't firing. Will post it separately in the right thread.
Thanks and hope to talk to you guys again.
