Got a mystery here. Bought a Bayliner 1950 Eagle with a 140 Mercruiser, VIN BLBA69EA1179. It sold to me as a 1979, yet NADA says Bayliner never made the Eagle in 1979 - or 1980. It shows up in 1981 but not with my Mercruiser 140. Can someone tell me what year this boat is? Also want to go to a stainless prop. This will occasionally pull a 200 lb skier or a tube but mostly it will be used as a fishing/pleasure cruiser. I want more top end speed than I want a super hole shot. Right now the motor turns 4200 rpm at WOT. Can't decipher the numbers on the current aluminum prop. Any recomendations?
