Transmission Neutral Point


Recommended Posts

Hey there! I’ve been having trouble with my 88 skier going into neutral, so here we go...

I got a new 5.7 put in her and they seemed to have messed up the neutral point on the transmission somehow. When the boat is first started the prop’s shaft/output shaft doesn’t spin sometimes(like it should), but other times it does. Also, if you pull out the neutral switch on the throttle you can see that the cable attached to the transmission doesn’t move but it seems to be still in gear and sort of jumps out of neutral when revved even the slightest amounts. Since even in the throttle’s idle position the transmission is still engaged  (not sure if it’s supposed to be in gear when idling or not, but it definitely shouldn’t be in gear when the neutral switch is pulled out and engaged so I know that at least something is wrong) I assume that the cable going to the transmission wasn’t set right and just needs to be adjusted but I wasn’t sure if it could cause problems with being in between gears and some grinding and stuff if done wrong.

So, the main question is if it’s okay to unbolt the throttle cable that goes to the transmission and adjust it some until the cable’s resting point is the same as the neutral for the transmission and if I could somehow mess something up with the transmission if I were to do that wrong. Also, if it’s safe to do that, how would I go about finding that neutral point? I assume just trial and error?
 

Thanks so much, this forum has been a great resource and I’m looking forward to becoming more active here, thanks again!

CAUTION - WITH ENGINE OFF: if you remove the shift cable at the transmission you should be able to feel a detent at neutral as you move that transmission shift lever.  

after finding that detent location you can work your way through the cable and shifter adjustment to insure the cable puts the lever in the detent when the shift lever is in neutral.

please use caution and understand that, with the shift lever disconnected, the engine can start AT WIDE OPEN THROTTLE when the trans lever is in neutral.

Perfect and thanks for the warnings, I’ll be sure not to move the throttle cable and mess up the connection already on the carb. Thanks.

You'll really want to take a look at the brass shifter control ends, as they wear and eventually break.  Your may be causing the issue.

Good point but I don’t think they’re causing my issue because the when neutral is engaged only the throttle cable on the carb is moving and not the one on the transmission
