2 Cylinder Johnson 40hp Old Trim/Tilt

[c_douce]

Hi, Purchased the old trim, the cylinder attached to the motor trims up, the opposite cylinder has no pressure, just slides, opened the, I would guess the refill valve that has a wire attached, no fluid inside, possible leaked out, if I refill, would It hold and due to that side not working, why does the opposite cylinder still trimming. Is there a detailed video how to dissemble and how to clean out the aluminum pressure hoses. I noticed a couple of boaters posted, but they never received an up-date on their last question. both cylinders are the same. hopefully someone on here has the experience to give me the info or details.

Read before you bring out the hammers.-----Both cylinders trim at the bottom.-----Only 1 cylinder tilts I believe.-----The 2 cylinders are NOT identical.

If it is this style you purchased the port cylinder with wire has a trim sender unit built into it. Also the port side is the trim and starboard is the tilt side

Revised, "R", thanks for the info, yes, I do know the trim is on the motor side, the other is the tilt, but I'm asking for more details of my ?'s, so I don't screw up anything, I will be filling the other cylinder today just to see if anything is leaking or is it dead.

Feiztbullet, yes, that's my trim. should I fill the cylinder, is it suppose to be full? The guy I purchased from mentioned, that side isn't needed?

This unit was used between 1973 and 1977 on the 50hp and above, except for the 1977 140.
I have never seen a Trim or Tilt unit like that on any 40hp

they had this adapter kit up through 1988 for the 2 cyl loopers. it was really kind of a lemon design IMO. better to get a CMC model 130. whole thing would rust out and just almost never work correctly. obviously a big reason for the 1989 re-design was because OMC needed a clean and light integrated trim/tilt solution to satisfy customers possibly looking to other brands.

The integrated System that replaced the Rube Goldberg device pictured was introduced on the 1976 V6, and migrated over the V4s and 3 cylinder Loopers by 78. Later 2 cylinder loopers used an entirely different system

Hi all, thanks for the replies and as you can see I attached my trim. It trims up and down without any issue, but as I'm driving, it slowly goes down, I have to stop, trim it back up, it does the job and not leaking. Can you suggest a detail fix or video how to fix it? It is the same exact fit on my 40hp, I just had to grinned a little off the top of the cover plate. My first boat, I had a 40hp Evinrude, sold it, purchased a 28hp and purchased the CMC PT35, which was perfect and yes, I should have bought the CMC130.

no tilt lock to keep it up instead of relying on the hydraulics?

a 2x4 should do it

 

[c_douce]

I should have been more exact. It has the tilt lock clip, but driving the boat on the water, it slowly tilts down.

that type of piston is NOT serviceable i believe. best find a good used one on ebay.
