just bought (TODAY) a 1987 Ebko Marine Malibu, 16' with 2.5L Mercruiser and Alpha One. Other than new upholstery, I need to replace the shift lever, I have to pull it out from the base to engage throttle only, the button lockout is gone/broken, missing. Also, the neutral position is WAY tilted backward, not straight up. Action is smooth (cables ok, I think), just need a replacement head. HELP! Where do I go, aftermarket, what type, possible to fix, etc.
