Re: Evirude 1991 40hp trim/tilt
I'm looking at the service manual.
If you raise the outboard, "engage the trail lock levers", and look just below the trim motor you should see the fill plug facing to the rear of the outboard.
It appears to be less than 1/2 inch below the base of the electric trim motor.
In the BRP parts diagram, the T&T diagram part #30 is the fill plug and is facing the rear of the engine as shown.
