It appears that according to NADA site, Yamaha produced 200 HP motors around the 390 LBS mark in the late 80s and through out the 90s, the later 90s seem to go up to around 412 LBS. Is this correct and does anyone know some one who may have one for sale with a 20" shaft? I would be willing to drive 6-8 hours from Savannah GA or pay for shipping from a reputable seller.
