I am thinking of replacing my 1999 115 hp 2 stroke yamaha motor with a new 4 stroke. The motor was bought new in 2001 with my boat. It has also just been professionally rebuilt, runs fantastic, and has less than 100 hrs. on it since. The dealer has only offered me $3000 as a trade-in. Seems a little bit low even for a dealer. Since I have not been following used prices on motors, I am not sure what to ask. The motor is in pristene condition and always flushed, lubed and maintained. Any advice or offers gladely accepted.
