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 any of the shift rods or the water tube run thru this exhaust tube or can I just disconnect the rods up top, drop the unit down far enough to gain clearance, insert the exhaust tube, and close it back up?<br />3. Are there any "tricky" parts to this install that I need to be aware of... like shift lever orientation or indexing of parts? Does the water tube re-seat itself?<br />4. Should I use a lube or coating on the exhaust tube seals before installing to help it seat correctly? <br />Any other suggestions or gotcha's would be greatly appreciated.
