BMS, I have most of the Lund brochures back to 1986, but not back to 1980. Here are the specs on the ’86 Mr. Pike. Transom Height 20″, Approx Weight 690 lbs., Max. weight capacity 1,300 lbs., Max H.P. 75, Beam 72″, Length 16′, Color – Lund Red with light tan deck and interior – oatmeal and red carpeting. Hope that helps and sorry I don’t have the ’80 brochure.
