lower unit installation

[thumpar]

If it doesn't want to come off you can use a short 2x4 between the housing and top of the drive while pushing the trim/trailer up to pry it off.

Thank you. I would be lost without you guys. I will do that and try lowering the rear mounts to drop the coupler. The only thing I can think of is the alignment tool was hitting metal while sliding past the bearing. I thought it was from the weight of the bar because when I lifted it up it slide in. Still have a shot of taking the kids fishing this weekend.

It does sound like a"U" joint noise. Did you check the joints when you had it off? An off center "U" joint would make sense for the hard install also.

Dosent work that way, rear mounts are fixed ,not adjustable. Any adjustments are done with the front mounts.

 

[andrewterri]

I did check and grease them and they looked okay. I just hope I can get that drive off

Your alignment bar may be off but I wouldn't go buy another just yet. Even if it wasn't made correctly you should still be able to adjust to get the drive on. Don't know what's going on yet but something is off

 

[andrewterri]

let me start by saying...user error. I lowered the motor using the single motor mount bolt that is located under the crankshaft pulley. I loosened it and the rear of the motor dropped and I was able to get the alignment bar in the coupler about an inch and get greased spline marks on the bar (I was wrong about the bar going in last time, I just thought it was). When I tried to loosen the bolt a little more, the washer under the bolt was loose but the motor would not rise up anymore. Does this mean the motor mount is bad? I was thinking the rubber had lost its elasticity and that's why it would not lift the motor anymore. The outdrive goes on very smoothly up until the last 1/2 inch. The 2x4 trick that someone mentioned worked like a charm, I never would have thought of that.

Thank you for the diagram. So it looks like I need to loosen the jamnut (C) along with the adjusting nut (A) and I can rise the motor up by tightening the locknut (B). Am I looking at that correctly?

 

[wrench 3]

I'm afraid that I'm having trouble rapping my head around your last post.
You say that you loosened a bolt on the front mount and the back of the engine dropped. The rear mounts do normally have some vertical play in them but the front mount shouldn't hold the back up unless the engine is rocking in the middle (like the oil pan resting on the bilge). Secondly, the adjustment on the front mount should be a stud under the mount with a nut above the bracket and one below the bracket to raise or lower the front of the engine. There is also a lock nut on the bottom.

I am sorry about not being clear. I am typing with a cast on do to a failed attempt at a romantic ski trip with the wife for valentines day so I am trying to be short. What I was thinking is since I can only adjust the bolt at the from of the engine (under crankshaft pulley) I thought by doing so it would allow the front of the engine to rise thereby lowering the bottom of the coupler. I did not know there were bolts under the adjusting nut shown in the figure above (A). I am trying to figure out what I need to do to lower the bottom of the coupler as I think that is my problem. When I loosened the adjusting nut I was able to get the alignment bar into the coupler about an inch. My thought is if I can adjust it more I will be able to get my alignment dead on.

I think the front of the engine is to low since I loosened the bolt which allowed it to raise got me closer. How do I raise it more? the adjustment nut it all the way loose. Can I turn the nut above the jam nut to raise it?

 

[Bt Doctur]

the top nut(a) turned clockwise will raise the front of the motor if nuts b and c are loose, counterclockwise lowers the front of the engine

 

[andrewterri]

Awesome, that was what I was wondering. I will do that in the morning. Thank you again, I will report back

Andrew -
To find out if you need to raise or lower the front of the engine you need to inspect the grease marks that the coupler splines leave on the alignment tool. Carefully pull the tool out without rotating it. If the marks from the spline are heavy towards the end of the tool on the top side, the front of the engine has to come up. If the marks are heavier towards the tip on the bottom then the front needs to be adjusted down.

BT Doc -
I wish I could find post-able graphics like that.

 

[andrewterri]

I was just about to ask that wrench 3. I am having thick heavy marks in the top of the tool and almost nothing on the bottom. I will go raise it up some more and see if that gets me there.

 

[andrewterri]

I am going to keep adjusting but I have been noticing the marks are thicker on the left side of the bar than the right. is there a way to adjust the motor side to side or is that a sign of a bad motor mount?
