Re: gw invader 10ft Power Options?
Welcome to the iboats.com forum. The experts here, which I am not, can help you with any question about your boat, motor and trailer. You probably did not get any response because you posted in the brand-specific forum. You might do better in one of the motor forums with those questions and the Restoration&Rebuild forum with questions about fixing up your boat. The members are great and can help in many ways.
I saw your other post about the rubrail and can tell you that the rivets can be removed by drilling them with a bit slightly larger the the hole in the head of the rivet. You don't need to drill all the way throught the rubrail, just enough to take off the head of the rivet. Once removed, you take a punch and push the remaining shaft of the rivet inside the boat. It's a lot of work and I personally do not think it is necessary to refinish your boat. Careful tapeing should be okay for a good looking paint job. Also, the repowering thing gets a little tricky because of any maximum horsepower ratings the manufacturer may have originally placed on that boat. You need to research that before making any motor decisions. Also, if the boat's transom measures 20inches, then that is what you will need for any other motor. You may need to shim any motor you use to get maximum performance.
You are great dad whose son will never forget this project. Good luck!
