lower unit

[ftmj76]

Can anyone tell me how to remove the lower unit from the motor of a 1990 40 HP Evinrude?

Re: lower unit

The generic answer to your question is to first,disconnect the shift rod linkage and then all of the lower unit bolts that connect the lower unit to the mid-section.Don't forget the bolt under the trim tab and once the lower unit is removed don't allow the shift rod to rotate from its original position or its critical length will be compromised and cause shift linkage problems once reassembled.First timers should always use a service manual as a guide in performing this task.Many timers often do as well.

Re: lower unit

I helped a bud put a new impellor in his 91' 50hp a couple of weeks ago. You'll need to remove the starter to get to the shift rod linkage. I'd disconnect the battery first to play it safe. Like ob said, a service manual is good to have.
