1955 Aluminum fishing boat (15 feet) with a 4 HP 4cycle air-cooled engine. Went through the entire boat...fixed/replaced lots of aluminum rivets then sealed all seams and rivets with a special epoxy made for aluminum boat repairs (amazon-Aluminum Boat Leak Sealer ((Total Boat)). Finally I painted the inside and outside of the boat with a white rubberized paint for additional sealing. The 4 HP Chinese brand motor (bought on E-Bay... Hangkai) is one year old and barely used...maybe 2 hours total. I went through the engine...removed and cleaned the carb...added new Champion spark plug. Removed and cleaned the gas tank and lines. Also greased the shaft. Took it out yesterday (26 May 2022) for a test run and runs great...boat dry. I have a video of the test run that I can text. Trailer in great shape and tires still good for a while longer...but, needs taillight setup. I have the title for the boat and trailer in hand. Cash only...local pick up...best offer takes it.
