I have a chance to purchase a '89 sea Nymph 15.5' with a Johnson 25hp for $500. The boat belongs to a friend and has been sitting for 10 years under a tarp and shelter most of the time. The boat cleaned up nicely however the flooring is rotten and needs replacing. The motor ran fine when it last ran. What do I need to do before I run the motor...fuel lines,tank, filter, carb rebuild? This is my first boat and any help is appreciated. Where are some good resources on the internet for rplacing the flooring and engine parts? Is $500 a good buy for a boat that needs some work and the trailer needs new tires? Again thanks!
