OMC drive

[orca]

I am having a problem with an OMC drive. The model No. on the drive bracket is 984609 which does not corrospond with any charts that i can find. however the motor covers are for a 175HP johnson ocean runner of about 1994 vintage, 60 deg vee. I am not aware of OMC making a C drive like this, It may be made up from an outboard. if so it is a good job.<br />The problem that I have is the gearbox will not drop. all the bolts are out and the gearshift is disconnected, the box is dropping about 1/4". Has anyone had any problems with the drive shafts sticking on these motors like some of the early mercs and Yamaha motors.

Re: OMC drive

i have very similar, mine is 1991 225 sea drive.<br /><br />my lower unit dropped perfectly. wehn you undid the shift linkage, did you loosen the screw that holds it, or completely remove the screw. i must be completely removed before any dropping will occur <br /><br />mike<br /><br />peace

Re: OMC drive

I assume you got the bolt that is under the trim tab on the lower unit. That said, yep, the driveshaft sure can stick in these motors. Can be a real PITA, happened to the counter rotator of my pair of 2.0L SeaDrives. I got lucky and got it loose with the help of two wonder bars stuck in the opening. Good luck with it.

Re: OMC drive

Are you sure you have a Sea Drive? Could it be a Quiet Rider instead?
