Montgomery Ward Sea King 6hp
Jul 09, 2006 If I remember right the very last 2 digits of the serial number is the year of it. You might also have to take serial number into someplace that sells boat parts and they might be able to look it up for you by the serial number. 12' 1975 montgomery ward sea king v-hull aluminum boat w/ new galvanized trailer. Dutton-lainson brand. Yamaha 2005 2 stroke 8 hp outboard, with under 30 hrs. Boat is tight with zero leaks, and has swivel seats. 2 3 gallon gas tanks with fittings and hoses. Tongue lock for trailer, and straps. Totally restored!
