    1984 75hp Merc - Trim goes all the way up but only 85% of the way back down?

    The title pretty much tells the whole story/problem. My trim will go all the way and only about 85% of the way down. When I bought this boat/motor to fix last Sunday the trim wouldn't go up. I lifted it up as the prior owner added fluid. Then it worked so it had been sitting w/ low fluid for a...

I took off the head and here is what I found. Does this...

    onboard charger - voltage too high - 17.5V!

    I have an older Bass Pro XPS / Pro Mariner 3 bank onboard charger. It's been in a box for a while. We're finally getting settled into our new home and I was in the garage getting ready to install it in my boat. Before installing it I hooked it up to 1 battery and plugged it in. The output...

    90hp - 90ETLJ - Just not quite "perfect"

    Thanks nayborbob2! I appreciate the helpful post/reply. I'm glad you got your 70hp running better. Since I posted, I removed and cleaned my carbs and now it runs perfect. I obtained 5200 RPM smooth as silk and about 40 MPH in a heavy and junky fiberglass boat that came with the motor. I'm...

    1992 70hp Rude - Perfect except she dies at idle after idling for a few minutes

    I have a pristine 1992 Evindrude 70hp on my 16 foot smokercraft. I couldn't be happier with this engine except when I'm using it for trolling umbrella rigs.
