Had to drop lower end on my '98 Johnson 90 HP outboard. <br />Got the shift rod disconnected to allow the lower end to be dropped... but had a helluva time getting the rod reconnected on re-assembly. Had to loosen the pans just to be able to get a glimpse at what I was doing. Still took a ton of...
My rebuilder left out the lower unit exhaust tube on my '98 Johnson 90HP motor.<br />I have the tube and Seloc book, but need some help on the procedure.<br />1. Do I need to drain the gear lube or is that contained is a housing that won't be distrubed when I separate the lower unit?<br />2. Do...

I just launched my 17' CC with a rebuilt 98 Johnson 90HP motor. I can't believe how much louder the exhaust note is than my previous 91 Johnson 90HP motor.
