Default throttle stuck after out drive install

Re: Alpha One Generation 2. I re-installed the upper part of the out drive today first, seemed to go in well, and all the bolts went in easy. Then I re-installed the lower unit. I didn't expect it would just slide in, so I though not being able to close the gap between the upper and lower units was maybe normal. When I tightened up the bolts, no problem, it closed right up nicely, EXCEPT, while tightening one of the bolts, I heard thud. Then it seem to close up fine as I tightened the bolts. When I went to start it (throttle all the way forward during assembly) I went to put in in neutral first, and after a little movement aft, and into neutral, the throttle shifter became stuck and cannot be moved in either direction. Would bad alignment be the problem (obviously) and would that be from the lower unit being not aligned at he linkage? I did move around the lower unit a little more than I was thinking as I had to stop to show my assistant (wife) which way to turn a nut to tighten. Maybe the two pieces that need to align (the right angle rod and where it sits on the upper drive) changed position. Does this make sense to anyone? Thanks.

The alpha units must be removed and install with he shifter in forward, sounds like you did this. When installing the lower half it's shift shaft must be in forward, the shaft is located on the forward upper part of the lower unit. It has a rectangler shape. You have to put it into forward and to make sure it stays there by apply slight countercloclk wise pressure (grap the shaft with you hand and lightly twist) on the prop shaft as you install the unit. Once the two halves are mated verify the lower shift shaft is sitting within the upside down U of the upper shift shaft.

BTY: don't forget to install a new O-ring on the lower units wall (right hand side) to seal the lube tube.

Thanks Mike. Can you see if the two mate after you install the lower unit? I do think that we may have moved the unit around enough to more it so it wasn't pointing forward. Thanks for the idea of turning the prop shaft counter clockwise to keep it there. I am hoping I didn't do any damage, and that I can drop the lower drive and repeat the process, this time holding the prop shaft. You have been a lot of help since I joined the club. Thanks so much! I will let you know how it turns out tomorrow.

Oh, I replaced all the seals and O-rings today. Should I need to replace it again if it is OK?

May I ask why you are not assembling the outdrive and then sliding it into the transom? When I did my impeller, I had great luck and it seemed to go right together.

Guess it was a weight thing JP? It would be like 90 lbs put together. Oh well, I will drop the lower half and see if any damage was done, then try again.

If the throttle moves freely, after I take off the lower unit,then I will know the upper unit is assembled correctly. Thanks.

HL glad to help. The O-ring should be fine. Yes you can see the joint between the upper and lower once matted. I suspect it will be ok as I have done this once myself, that's how I knew what you did.

BTY installing the complete outdrive still requires light load on the prop shaft to ensure it stays in forward.

Mike, did you have to drain all the oil out again, or can I drain half, and be able to realign the joint without fully dropping the lower unit?

OK, Part II: I lowered the unit and saw the alignment was off. Dropped unit enough to get her in the slot. Replace oil that had to be drained (about 3/4) and having a sandwich before turning the key. Hate to turn the key with a beer on an empty stomach....lol. And yes, the throttle moves back and forth nicely now.

Sounds like you answered your own question and are back in business

Well, almost Mike. I turned the key, beer in hand, and it started. The wife and I clapped, but in about 13 seconds, it died. After that is would turn over, but not start. I am wondering if I missed the alignment for the copper and black pipe that connects to the upper unit. Could that cause me to not be able to start after a few seconds? I mean it was running, though I wasn't able to throttle it up to rev the engine. the throttle felt fine, just that the engine didn't want to rev. I will wait to hear from you before dropping the lower unite...again. Hey, they is how you learn stuff. If I could have pulled this off the first time, I would be a marine mechanic in the Caribbean...

The engine doesn't care if you are giving it water or not so misaligned water tube isn't the issue.

Sounds like a differnt issue. The engine is turning over so now need to verify spark and fuel. When you push the throttle forward can you see gas squirk in the carb (wife's help is need here). If Ok then need to check for spark at the plug wires. Use either a timing light or spark tester for this.
