OK here we go again.....new mills are in rigged and almost ready to fire. I go to put the drives on and no dice....I can just get the threads in the case and major stoppage.....I really cant adjust anything with the solid mounts,Tinkerboater is running his alignment tool over tonight for me to check them any ideas?

Is this a Bravo type setup Dyno?

yep...

If the drives came off easily, then it's probaly not the offshore mounts. Do you have the spring/fiber washer in correct? Easy to knock them off when the motors swinging. In that case back of motor would be down 1/8" and screw up alignment. I assume you have drive in gear so that you can rotate drive shaft to match splines in coupler.

If non of that is the case remove front engine mount bolts and try putting shims in between mount and engine.

Either way I don't think it's agood idea to put drives on without using alignment tool at any time.

Good luck

Also, if back bolts to gimbal housing not tight this can be cause of problem. My offshore mount has not changed alignment over the year Ive had it. Drive and motor out twice.

By shims i mean about 1/16" pieces of metal sheet. Then you can drill them to match mount bolt pattern.

I put the back bolts in with an impact,the fibre washers and springs are in...witht the offshore Gil mounts you really cant shim them.....

Dyno,

Pretty sure there is a torque figure for those bolts. I use a half inch rachet moderatly tight.

Correct order is bolt, big washer then metal spacer, thru rubber mount in Flywheel housing then fiber washer with spring inside to gimbal housing.

Spring can end up sitting on fiber washer. Metal washer in wrong place etc.

Guilty of getting this wrong myself , so I check order twice before final bolt down.

Cant find pick of gil offshore mount, is it like mercruiser one?

look 2 posts up, pic attached

I think you can shim, Of course you can only go up with front of motor. Pain in the but. Shim idea is to find out if front of motor has sagged. If you get good line up with them you may have to drill bolt holes in mount little larger so you can get bolts in with spacers. Or loosen/ take out the bolts where mounts bolt to angle brackets on stringers get alignment and drill some new holes.

I find it hard to beleive that you have lost alignment on two motors. Have you changed couplers or universal joints? Even a different trailer could cause a problem .
