Please help drive alignemnt
 

Im installing my drive back on the boat after having the motor out. I ordered the tool to line it up but I have tried everything to try and get this tool in there and seems the motor is still off just a little bit the tool willnot go in. Looks like the back of the motor needs to move over just a little is there any side to side ajustment????? Oh and it a bravo out drive on a 502mpi. thanks guys worked on this thing for hour and getting no where. GURRRRRRRRR:angry-smiley-038:

Is it possibly I knocked the gimble bearing out of place a little when I pulled the drive??? I dont have a drive stand and I just pulled it off with out one and im just wondering if this could have happened? The reason I say that is because it showing the back of the engine needs to move the the side a little and theres no side to side adjustment I dont think. I do just have the studs up front for mounted and I put them as close to how they where before I pulled the engine. Thanks guys for the help.

Dont forget that the gimbal bearing is made to pivot, it may be tight, but it will pivot.

Ok I didnt know that. I will check on that I bet that will help me alot I was thinking it did not move at all. Thank you.

I usually install the alignment tool in the coupler, then give a good thud on the alignment tool up, down, left, then right. This usually lines the gimbal bearing up.

(with the palm of your hand or a rubber mallet)

YUP,

usually works for me too.

Funny story.......

It had been so long since I had done an engine on an I/O(switched to outboards when I moved to FL), I forgot about that little fact also. Was helping a friend replace stringers in his scarab, and pop the engine back in. We made templates before removing the stringers, so were pretty sure we had the engine mounts back in the right place. Had my buddy buy the parts from a local Mercury dealer(and OSO member), then when we were ready borrowed the alignment tool from same guy. I tried for 2 nights to get that thing to line up, but just couldnt get it. Said to my buddy, haul the boat over to him, return his tool, and tell him you want to pay him to do the work. He looks my budy in the eye, and says "Tell Rick to get his head out of his azz, and pivot the gimbal bearing" Buddy calls me and tells me this, I bang my head against the wall, and went back to the shop that night, had it aligned in 15 minutes.

Thats funny,

Had a friend struggling with his, went over to help him, when he went around the corner to get something, I did this quickly and when he came back I said got it for you. He couldn't figure out how I lined it up so quick.

Cool guys thanks for the replies. Im about to go and try that I was so mad about midnight last night I had to leave the shop and go home lol I could not get it to work for the life of me. I bet it goes right in lol. So just put the alignment tool in the gimble bearing and move it up and down left and right with a light bump before pushing it in the splines so the bearing getting centered in the housing?? Again thanks for all the help guy. :coolcowboy:

Put it thru the gimbal bearing, and as far as it will go in without forcing it, hold the tool in with one hand and light pressure, tap the farthest point of the tool from the transom with a fist, or rubber hammer up, down, right and left, until it pops in. This may work first time, but then again, you could possible still be out of alignment after trying everything last night. If the bearing doesnt seem like it is moving, pull the tool out a bit, and try again, you should feel the bearing move a good amount in its race in all directions. I actually mark my tool before removing the engine, so I know for sure when I put it back in that it is fully seated.

I want to thank everyone for the help. I went home with everyones advice and in three min it was all lined up and could move the tool in all the way with two fingers and pull it back out. Put the grease on it and had good pattern. Once again thanks OSO MEMBERS. :thankyouthankyou:

Glad you got it worked out

after i get the alignment tool in, i start the engine for 5 seconds. bearing has no choice but to center up,. there is essentially no side-side adjustment on engine. just up-down.

With no water to the engine?

I would not start that thing up with the drive off. I dont think that alignment tool will stay in there and it might come flying out of there and then you will have a big mess. And with no water i think you are going to burn up your impeller. DOnt DO It.

Guess you could pull the coil wire, and crank it over, but not sure if that would have the same effect.

after getting the motor back in and the drive all lined up and installed took the boat to the lake last night and it runs like a champ. Just in time for the Texas Outlaw Chanllenge. :lolhit::evilb::coolcowboy::ernaehrung004::flag:

there is another part to alignment tool, disc similar to u-joint bellows, fits from inside when putting inside transom plate to external transom plate. put alignment tool to line both transom plates prior to torquing nuts. the motor mount rigging grid for new engine install goes with it.

Another thing I ran into years ago with a Bravo.. I would line up the engine, two finger slide in and out. I had to move the motor a lot, didnt seem right. Then I rotated the motor 90/180* and tried it again. It would not go in. I figured the donut was warped. After alot of hours of frustration, I pulled the engine again and borrowed a coupler from a friend. Lined up the motor (solid motor mounts) and pulled the engine again and swapped in the old coupler. Ran for years without a problem. So a quick check spinning the motor 180* will tell you if you actually have a good alignment. In this case, it would have been way off due to one quick check.. Since then I have not found another warped coupler, so it was a rare situation, but can happen.

Good info, never thought of that.
