    Prop Locking Question (Reverse Locking Cam?)

    I see the spring, at first I though it looked like it is on the racketed side of the dog clutch so would push to reverse from the drawing, but I’m guessing it actually pushes on the shaft, cause the dog to move towards the ratcheted side, relative to the shaft (which would explain the clacking...

    Prop Locking Question (Reverse Locking Cam?)

    Never…just purchased. Sounds like time to open Pandora’s box. My assumption is that I need to drop the lower unit before I can access the drive shaft area (where the reverse came lives). If the issue is in the dog clutch, that’s in the LU as well. Do you think that it is worth changing...

    Prop Locking Question (Reverse Locking Cam?)

    The unit was only shifting between forward and what didn’t feel like a free spinning reverse. So I was exercising the upper shift lever directly (no linkage or cables) and turning the prop by hand to check lock status (I later found out that turn the prop was critical to shifting to reverse)...

    Prop Locking Question (Reverse Locking Cam?)

    No. I was working on a starting issue and trying to eliminate obstacles to a clean start (one being drag from the prop not spinning completely free in neutral). In doing so, I realized that the only time the prop spun free was when the remote registered full reverse (ie, the was no reverse...

    Prop Locking Question (Reverse Locking Cam?)

    I see; you are responding to my comment about the shaft being locked with only ~40deg of free movement. (I put that in to confirm that the prop is indeed in reverse) My primary concern right now is that I cannot get the clutch dog to back out, so the LU can re-enter neutral. What I’m looking...

    Prop Locking Question (Reverse Locking Cam?)

    I don’t understand that reply…should I try to push it out of reverse even though it doesn’t feel like it’s going? I’m concerned because it seems that I am where I am because I trying to get it into reverse without prop rotation. I don’t want to break/bend anything, as parts for this motor...

    Prop Locking Question (Reverse Locking Cam?)

    Trying to push it out of gear is like pushing a wall…not springy like when I was push into reverse without rotating. The prop is locked in one direct and turns the shaft in the other. I don’t want to break anything, so if there is a trick in this direction too, let me know before I lean into it.

    Prop Locking Question (Reverse Locking Cam?)

    Well that explains how it got into reverse (I had one hand on the prop and one on the lever. The question now is how can I get it OUT of reverse.

    Prop Locking Question (Reverse Locking Cam?)

    No, moved the shift level back and forth several time and Clunk, it found reverse, I pulled it back and it went into reverse again (ie, prop is locked in both directions with about 40 def free movement). But now it seems to be stuck there.

    Prop Locking Question (Reverse Locking Cam?)

    Ok. So I removed the linkage to the shift slide, thereby allowing the shift arm to pass under the carb bowl. It slipped right passed the SHOT to the far side under the force of a spring. I was able to pull it back to the port side, but now I can’t feel any gear shifting at all and their is a...

    Prop Locking Question (Reverse Locking Cam?)

    See photos. The first is the shifter hitting the carb. Second shifter at the fwd point. The next is the slide position if I manually push the shifter back until the prop stops click and spins free. And the 4th is where the slide snaps back to as soon as the pressure is off (returning the...

    Prop Locking Question (Reverse Locking Cam?)

    Thanks Brodman. The motor runs well and for a prolonged test period once started (long after the ether is gone), and posts elsewhere mentioned that week spark and/or the lower unit not truly being in neutral might be the issue. As mentioned in my last post, I cannot manually get the slide to...

    Prop Locking Question (Reverse Locking Cam?)

    Ok...so I shifted the Remote to Neutral and disconnected the shift (lower) cable from the slide. Manually moving the shift lever, I can feel where FWD ends and neutral begins (about 2.5-3" before the end of the slide, as it takes some pressure to get over that leaving you at 2-2.5" about the...

    Prop Locking Question (Reverse Locking Cam?)

    That could be it, since neutral in the motor and prop does not agree with the remote on the other end of the cable. I'll reset the Neutral so that the handle is straight up rather than pulled back 10degrees. Maybe there is a relationship between the two cables I am not considering, in addition...

    Prop Locking Question (Reverse Locking Cam?)

    I'm new, so bear with me. 1973 Thunderbolt 850; just purchased and rebuilt carbs and in boat electrical. She starts, but only on ether (suspect is weak spark due to old plug wires---solid copper replacements on order), but the prop does not seem to free up in Neutral as i would expect...its not...
