Let's start by saying I just got my brother's boat and motor off him and have actually made some headway with it. My brother is Loopie on this site he has pics of the motor in question. He neglected to tell me though that he ran a riverbank a couple times and messed up the shifter/LU unit. I got it running on both cylinders again (coil wire was broken, replaced both) and now my problem is in the LU not shifting out of drive/forward. It is a manual shift and should be pretty straight forward. I have the LU off of it right now but, I haven't tore it apart yet. Is there anything I should know before dis-assembly of the LU? I don't have a manual and am a mechanic by trade so that will help with things. Any and all help is very appreciated.
The problem is it will not shift at the LU but, the upper mechanism is working good. Brother "loopie" has a complete 56/57 Johnson 35 will that LU work on my motor being a 59? If it will is there any mod's I have to do?
