I new to boating and apologize for sounding dumb. I just purchased this Boat and Motor about a week ago. The motor is a 1967 Johnson 40hp. The question is how to I know if this is an electric shift or mechanical shift? I have read threads on here that state that the lower unit lube is different for the two. I have a throttle control on the right hand side of the boat that has F-N-R. Now the funny thing is that I noticed that if I take the throttle lever to F is actually puts the boat in Reverse and taking the lever to R puts it to forward. I wouldn?t think this is normal and hope it would be an easy fix?
