HI People, Just new here so thanks for having me!

My question is this, Father owns a 2000 Johnson in 150hp but has just started to grind when putting it into reverse, cable adjustment has been checked and appeared fine, Its in the shop now and they have said that the gears are fine but there is a switch that needs looked at. Can anyone tell me what this switch is and if it is an easy fix, are parts easily available?

Cheers
Mal
 
If anyone has had the lower unit off recently who is not aware of the critical length adjustment of the shifting rod, it is quite possible that they have screwed it out of adjustment. If so, it will be impossible to adjust the shift cable until the lower unit shift rod is once again adjusted to its proper length.

Short notice: Some boaters with manual shift engines have the mistaken belief that shifting slowly is taking it easy on all of the shifting components..... Wrong! Shifting slowly allows those precisely machined sharp edges of the dog and gears to click, clank, bang, slam against each other many times before they are finally forced into alignment with each other..... and this is what rounds those edges off! The proper way to shift is to snap the unit into gear as quickly as possible.

If indeed the shift rod has been turned out of adjustment, attempting the following is a waste of time, however I am including it for reference.

(Centering Shift Cable)
(J. Reeves)

When all is as it should be, the proper method to adjust the shift cable is to disconnect the cable from the engine. Move the shift linkage on the engine to find the center of the play in neutral, and when found, leave it centered.

Now, grab the end of the shift cable sleeve, push and pull it to find the center of the play there, and center that play.

Adjust the trunion on the threaded portion of the shift cable so that the centered play of the cable lines up with the centered play of the engine's shift linkage. Install and lock the shift cable with the retaining clamp in that position. That's it.

Trim the motor down and take your foot and push down on cavation plate to see if it moves, then look at bolts under front of block. The 60° motors have a habit of upper motor mount bolts becoming loose and bends the angle of shift rod.

And one more thing.......The shift shaft cover on the lower unit, the Aluminum cover swells with corrosion where the oring seal is and pinches around the shaft making for hard shifts.

Shift interrupt on J/E outboards help with coming out of gear. If the switch was disconnected you would hardly notice.
 
Well its been in the shop for a while now and they still havent fixed it, they mentioned some salt around some seals in the lower end and thought that was the issue but NO.
Back to the switch again now but im wondering if they are now just guessing!

Is there any good video links for adjusting shift cable on a 1982 evinrude 150hp.
 
Step #1 is to check shift rod height.----And shifting should be done with a " quick / firm motion " and " granny shifting " is bad for the clutch dog and gears.
