I have a 1986 Glasstream Boat that is in really good shape but it needs some little things done to it like replacing the seats, replacing or repairing some of the gauges such as the gas gauge , there is a sending unit and a gauge but no wire coming from the gauge to the sending unit. I have not been able to find a wiring diagram or any kind of manual for it only one for the engine. Can anyone offer any suggestions ? The motor runs well and it handles nicely on the water. I would also like to re-paint and gel-coat the top half but cant seem to find the right kind of paint
