    Prop Locking Question (Reverse Locking Cam?)

    Thanks. Current situation: with the LU dropped, I can shift to reverse with a wrench, but when it pops (in either direction, there is nothing, and if that is after I raise the LU, it cannot be sifted back to reverse. So something is definitely not right in the gearbox (either a dog issue or...

    Prop Locking Question (Reverse Locking Cam?)

    Check this out! I used the special wrench to remove the carrier retainer. And the. Set about trying to pull the carrier. While I was failing at that I noticed something bouncing around in the Outer LU I have no way of explaining it, and I cannot imagine how it relates to my issues but I just...

    Prop Locking Question (Reverse Locking Cam?)

    Question: I’m looking at a lot of LUs on eBay, I notice that many/most oook different in the case of the shift/shaft spline. It looks like the connector from the bottom of the upper shift shaft is connected to the top of the lower shift shaft. Mine is the opposite (so my lower shaft extends...

    Prop Locking Question (Reverse Locking Cam?)

    BTW: does anyone have a part number for a gear replacement set (a kit). I know they exist for some models but have not found a list. In the interim, I tracked down replacement parts for just about everything in the LU (except for a decent full LU replacement under $1K)

    Prop Locking Question (Reverse Locking Cam?)

    Thanks for the pictures BTW, neither are in the (1966-74) service manual I have.

    Prop Locking Question (Reverse Locking Cam?)

    This is what I did before heading to the lake. When that failed, and I did it again, except putting together in reverse, I removed the reverse-locking cam to eliminate it from the issue (so it wouldn’t be a distraction, since it is only a position indicator in terms of shifting…the shift can is...

    Prop Locking Question (Reverse Locking Cam?)

    Thank you for this. I’ve seen this posted elsewhere. In my case, I’m not finding a forward gear at all. I can feel three distinct positions in the gear box, and those positions align with the three positions of the shifter in the motor and the handle in the remote. Reverse is the only gear...

    Prop Locking Question (Reverse Locking Cam?)

    I don’t understand what you wrote above, but I think I’m headed that way. Today was my birthday, so we took her to a local lake…where she fell on her face but good. Roared like a mighty beast (so the tune up worked…although her RPMs are still too high), but then she limped out on the lake in...

    Prop Locking Question (Reverse Locking Cam?)

    Thank you, Chris. I did find the tube, hiding and stuck several inches up…used a wire hanger to fish it out…I saw it earlier, but it didn’t want to move and was the wrong color so I wasn’t sure. The power is out here, so working by flashlight was a must and turned out to be what I really...

    Prop Locking Question (Reverse Locking Cam?)

    Point taken. For now, I am back to having FWD, Neutral (though still not as free as i would expect), and REV. I have new grease in the LU and I'm trying to raise it up and into the shaft housing. Two issues: 1. The water tube is giving me hell aligning with the water pump housing, and my...

    Looks like $90 eBay; $275 store) for the dog, FWD: 125-200 REV: 99 (or less on eBay) Full LU: $1250-2500

    Prop Locking Question (Reverse Locking Cam?)

    Thanks. Pleasanton,CA Fingers crossed on getting things to shift with new lube (just waiting for shade to hit that area). I think I found the tool to open the gearbox (order 2 different ones and will send one back). Are LUs specific to the upper, or more generic?

    Prop Locking Question (Reverse Locking Cam?)

    I copy that,,,I’m just using it as a reference point in terms of alignment right now (and wondering it it was the problem with the shifting, as I can see how if it was out of alignment, the cam could get over rotated and then locked in reverse but reverse lock shaft falling off the cam cliff)...

    Prop Locking Question (Reverse Locking Cam?)

    Update: Aligning the reverse locking cam. Or trying at least. I can shift to reverse (turn drive shaft CW, prop shaft rotated CCW…reverse locking post pushed up by plateau on the recerse lock cam) and if I rotate the spline CW, the spring kicks in and throws the LU into FWD (CWdrive shaft-CW...

    Prop Locking Question (Reverse Locking Cam?)

    Ok. LU is down. I took some pictures…what looks to be sand by the water pump.(pic) The reverse lock cam looks pretty scored,(pic) and dented on the side of the cam (pic) that I assume doesn’t see action (over the cliff after the plateau). Looks like the pin from above may have travelled...

    Prop Locking Question (Reverse Locking Cam?)

    Well…I’m draining the LU (man does that stuff stink)…good news, no water, black as tar…bad news: plenty of metal on the magnet, and at least 1 chunck of something (something l, somewhere is broken)… Will drop the LU and the shaft-exhaust cover and pray that I find a broken reverse locking cam...

    Prop Locking Question (Reverse Locking Cam?)

    Today is a brand new day…I reconnected the shift linkage and cable and eased it forward. I thought I hit a home run, because now forward on the remote is forward on the shifter, and neutral is neutral. But I was wrong. No matter what gear it is in, the propeller still spins...

    Prop Locking Question (Reverse Locking Cam?)

    Question Jimmbo: is there a way to know whether the two shafts are connected and aligned from viewing the parallel shafts in the Exhaust Housing, or is it necessary to unpack the LU (to view the part you are referring to above as connecting the shafts)? (Looking at the manual, unpacking the LU...

    Prop Locking Question (Reverse Locking Cam?)

    Thanks. No power-trim installed. So: if the shift shafts were/are misaligned (either from the last time things were put together or as a result of what I was doing today (trying to find reverse without the prop turning), that seems like the easiest to check (as it doesn’t require...

    Prop Locking Question (Reverse Locking Cam?)

    Open question: How should I proceed to get the out of reverse. 1. Change the gear oil? 2. Drain/drop the L/U and inspect the Reverse locking cam on the shift shaft (another thread indicated that sometimes there is a point on the flat that if past due to over rotation, it can be difficult to...
