I currently have a soft bottom achilles dinghy with an 8hp nissan. Came across an Avon Rover from the early 2000’s with a 15hp yamaha 2-stroke. Never been kept in the water and stored out of the sun. It looks to be in great condition. Is there any reason to shy away from a dinghy that old if it has been cared for? Being Hypalon, is 20yr old glue an issue?
