28 HP Johnson Outboard "Rubber Mounts"

[captbecker]

Hello- I need some help--<br /><br /> I am hoping someone might give me some guidance.<br /><br />I have a 1989 Johnson 28HP SPL Outboard. <br />There are two upper rubber mounts (one on each side) just under and behind the housing that contains the steering<br />housing. These contain 3 bolts (two bolt into the vertical main housing and one that bolts to the steering housing) and two bonded rubber disks about 1 inch or so in diameter.<br />I assume they absorb shock or actually support the engine (?) in an isolated manor. One of these is broken-- the rubber<br />disks are gone. <br />I bought new ones from OMC (PN 325974 - Rubber Mount),<br />but find there is no way the new one is going to fit in since the rubber "uncompressed" size is about 1/4 inch too big for the space.<br /><br />Question? Is there an easy way to take the load off of these <br />rubber mounts so they are expanded to the uncompressed size----- so that I could slip the new ones in (they have slotted mounting holes?? OR does it require some rather extensive dis-assembly? (My Clymer Repair manual does not even mention these rubber mounts or their replacement).<br /><br />Thanks much--<br />Best regards-<br />**** Becker

Hi Captbecker, The best way to change these is to do some extensive work. Trying to force them in, ususlly breaks the new ones. You will need to have the motor on a board as if mounted to the transom. Remove the bolts on the lower mount covers and remove the covers. ( 2 on side, 2 thru holes in front) Take the nuts off the upper side mounts. Looking from front of motor, look below the lower engine pan. You should see the nut on the forward upper mount. Remove the nut. At this point, you will need to lift the main section up about an inch and then pull it back. It should seperate from the sterring/transom bracket. Put it together in the reverse. Be careful not to overtighten the nuts on the mounts, you can break the studs off. <br />Iceman....
