Just received a DT15C that has not been started in 15 years. Motor was grandfathers and it has been sitting in a shop for the whole time. Hes letting me put it on a boat and was wondering if there is anything in order to do to start it up and get it ready to boat again. I already plan to pour a small amount of oil into cylinder and pull to lubricate everything. Also probably clean the carb even though the fuel was drained when it went into storage. Also was thinking about replacing the impeller because of the potential dry rotting over time. Motor has little over 13 hours on it, was used as a kicker motor for a larger boat. Its a 2 cylinder 2 stroke oil injected outboard.
