I've got a problem with the trim on my boat.

If I move the switch up or down, I can hear the relay switches click (I
believe that they are relay switches) but the motor does not move up or
down.

In the throttle, I have a green wire, blue wire, and a red wire. I

tracked

that down to a box on the boat. The blue and green wire connect into
separate relay switches, with the same color wire going back out and to

the

trim motor. The red wire connects to a panel in the box.

My experiments to try to correct the problem:

If I place the main wires to the trim motor onto the battery, it makes

the

motor trim work, green + blue - makes the motor go down, blue + green -
makes the motor go up.

With it all hooked back up.... if I connect the red wire from the trim
switch to the negative on the battery.... and then connect a wire from

the

negative to a bare spot on the green wire AND another wire from the

negative

to a bare spot on the blue wire.... the trim switch makes the motor
move

up

and down just like it is supposed to.... BUT the wires got HOT HOT HOT

and

some of the insulation burned.... spark etc.... so I stopped, decided

that

I

really should see of someone would offer a suggestion.

Again, if it is all hooked up properly (So I believe) I just hear the

relay

switches click but no movement on the motor. I REALLY would appreciate

some

assistance!






The relay's contacts commonly fail on that T&T system. I see you now
know why they use relays for polarity switching instead of running all
that current to the trim switch!

The relays are OMC part #582472(some are #584416). I carry a spare so
that we can always get the motor up or down as needed. You will
probably find that only one has failed - an armature has broken or siezed.

In the process of nursing my old Mariner through 12 years and 3000 hours I went
through several of these solenoids. The last ones I bought were sold as lawn
tractor starter solenoids at the BORG and they lasted a lot longer than the
"official" mercury unit. It was an exact fit and about half price.
Merc/OMC does not make these things, they are bought "off the shelf" from a
relay maker, put in a logo'ed box, marked up egregiously and sold as an
"outboard" part.
In their defense, it is not cheap to maintain a part logistics stream, stocking
every part in a motor but you don't need to play.
BTW have you ever bought a bolt at a motor dealer? In one of my rebuilding
projects I replaced every fastener I pulled out. I just dropped them on the
counter at an industrial fastener place and saved about $50, getting superior
bolts.
PS, don't forget the internet. I needed some bolts that were unobtanium in the
US in stainless (commie metric stuff) but were off the shelf in Germany. Even
with shipping they were a lot cheaper than Merc "special order" and I got them
faster.

AND not ignition protected.

Generally not true. Electrical parts for outboards are usually built to
spec, yes, often by an outside supplier, and are USCG ignition
protected. They absolutely resemble regular automotive or industrial
non ignition protected parts and will provide the same function but it
would be very irresponsible for an outboard manufacturer or service
professional to use the generic (non-marine specific) parts.

Technically, you could not pass a Courtesy Inspection with the generic
parts, but no Power Squadron or Coast Guard member has ever checked much
beyond fuel containment, ventilation, and intake spark arrestors on our
boats for ignition protection.

The parts on this unit are 5-prong cube-style relays and are available
in the aftermarket. I've never seen one on a lawn tractor.

.... USCG ignition protected....

This is under an outboard cover NOT in a bilge. BTW the Mercury unit DOES NOT
have any USCG approval numbers on it either so it is no more "approved" than
something you get from the auto parts store. If it doesn't say USCG and a
number it isn't USCG approved to a boarding officer.
If you take these apart they are made exactly the same (same covers, same
gasket) except the lawn tractor has a bigger contact pad.

These are round deals with 1/4-20 lugs sticking out the sides and smaller 10-24
coil terminals

Maybe, but the OMC relays are mounted in a relay/connection box on board
the boat, and usually in the vicinity of fuel tanks and the battery(ies).

No wonder they went out of business ;-)

The location is up to the installer, not the factory. Our 1981 V-4, for
example, has never had a relay fail, but it was installed high & dry and
is stored inside. Our 1973 V-4, with the "lawn mower-automotive" type
relays, is all original too, although mounted lower in the Glastron and
next to the battery, it too is always indoors or in a hoist.
