Re: Tell us how old is your boat?
1962 Glasspar Tacoma w/40hp Mercury, 1963 Starcraft (Jupiter?) w/ 70hp Johson, 1967 Starcraft Starchief, w/135 Evinrude, 1977 Starcraft Capri 17 w/90hp Evinrude, 1989, Duranautic 12' w/9.9hp Johnson, and a 60's 12' Sears jon boat (Lowes made and was last registered in 1964 when I got it), which has a 9.5hp Evinrude.
The '67 Starchief will soon be getting a motor upgrade since I just found a mint late model Mercury to hang on it in place of the mid 70's 135.
