Imco drive will not go on.
Im having quite the week,now my Imco shorty wont go all the way on,it stops about 2 inches away and I cant get nuts on the studs to draw it in.This is a new setup ITS box longer shaft XR,and Im wondering why.The motor was aligned properly and it looks dead on through the gimble.My other boat with bravos slip right in ,this was like hitting a brick wall.Is there a different gimble bearing for th xr shaft?The alignment tool slid in and out perfect so whats the trick?

Re: Imco drive will not go on.
there is a difference between xr and reg. bravo . usually the xr bearing has a red dot on the outer lip. and the line up shaft of a reg. bravo slides rite in but the diameter of it is slightly smaller, hense why the line up is good and the drive wont slide on.

Re: Imco drive will not go on.
Are you removing a Bravo and installing an IMCO ? If you are, dont you need to cut the lower portion of the bell housing off to allow the drive to be able to slip all the way up? All the IMCO drives I have installed I had to cut the lower portion offthe bell off. Or are you just onstalling a lower unit on a stock upper?

Re: Imco drive will not go on.
Yes Im installing a complete Imco upper and lower,the drive stops at about the same spot as the taper is on the shaft after o rings.Cutting the housing?I will look at the bearing and see if it has a red dot.I took my old shaft from the IMCO and it slid all the way in,but I changed the shaft to accomodate the ITS 7 inches longer and I was told it is an xr shaft with bigger u joints.My theory was wrong gimble bearing.Anyone care tp post?Just went out and checked red dot on ring

Re: Imco drive will not go on.
make sure you are not using to much grease on the two o-rings on the shaft. that will cause some problems. and also check the width of the gimbal ring where the wear plates are maybe you are binding up there. mercury uses plastic plates on the drive i think imco does not. there is also a special alignment tool for the its setup. you cannot use the regular one for standard length drives it is to short.

Re: Imco drive will not go on.
Do not use the nuts on the studs to ever draw any drive in or close the gap. If you cannot push it all the way then you have an obstruction. If you draw it in you will surely be damaging/cracking something.

Re: Imco drive will not go on.
Why dont you put a light dustig of baby powder on the input shaft to see if its causing the bind.
