Hi I'm Karen from Alaska. I just bought a 79 Glastron GT 150. Hope to polish up the hull this winter and will be looking for advice on how to do so. It's my first power boat, but it was just too cool a boat to pass up. Has a 90 hp Mercury motor. Not sure the year, but old. Everything works, but some sun fading and will redo the seats this winter. Very excited to own this boat - went waterskiing with it last weekend to try it out.
