F225TXRD tilt/trim relay & motor amp draw

[fairdeal]

First, I have to say that "69J-81950-11-00 RELAY ASSY" is bizarre. There are many parts of the motor that are impressively, elegantly, designed. But that tilt/trim relay looks like it was put together by two hillbillies with the aid of a considerable amount of beer.

Moving on - here's the measured amperages:

relay "up" 2.6 amps
relay "down" 2.4 amps

seems odd, but they are two completely separate coils

tilt/trim pump motor "from full down to full up"
during "trim" 16 amps
during "tilt" 29 amps

tilt/trim, pump motor "from full up to full down"
during "tilt" 20 amps, dropping to 10
during "trim 42 amps, dropping to 30

Obviously some very complex hydraulic stuff going on...

Here's some videos - you can hear the pump running while while the meter displays

From your written data, all seems normal to me as loads vary along the "journey". Your digital meter appears to have a long refresh time - always a difficulty in interpreting a smooth flow of change with digital meters.

looks about right to me.
as far as hillbillies and beer ? how would you design a polarity reversing relay that uses less than 5 amps to control a 50 amp draw?
remember the motor polarity must be reversed for up and down.

[fairdeal]

I wasn't presuming to criticize the functional design, just commenting on the appearance.

Rodbolt is used to looking at it.

From the schematic I knew what was there functionally.

But pulling the cover off and actually seeing it was a real WTF?


For one thing, I wasn't expecting the coil leads to be external.

Nor was I expecting the unused duplicate switched terminals.

Interesting to see the little screws - I'm imagining it might actually be "serviceable" - i.e. open it up and clean the contacts

Solid state.

This worked just fine on my '74 Evinrude 140, 30+ years ago.

They still make/sell this at about $75 a pop. If you need and can't afford the $280 Yamaha genuine part and have the room to mount it securely, why not use this?

For the Mercury branded Yamaha motors sold by Mercury, if and when a trim and tilt relay assembly craps out, instead of installing an over priced Yamaha trim and tilt relay assembly Mercury offers a modification so that ten buck a pop Bosch style relay assemblies can be used.

4 switched terminals, 2 coil "+" connectors (and integral grounds)
That's all.
Now that's an elegant design.

Compared to the 8 terminal, 4 wire coil lead, multiple-external-jumper Yamaha part....

Update, Amazon has the relay for $20.49. ***!!!https://www.amazon.com/Reversing-Con...or%2C+Windlass

I am waiting for Yam to offer a wireless control box. And wireless gauges.

For theft prevention the operator will simply remove his control box from the boat and take it with him when he leaves.

The mount for the control box will provide electrical power to the control box when it is installed. The ECU in the control box will only talk to its own motor(s).

We can fly drones over Afghanistan from the USA. Surely we can control a motor from 15, 20, 30 feet away.

Now shame on the owner if he travels miles to get to his boat and forgets to take the control box with him. Bet it only happens one time!

I would never admit it if I did

kind of like leaving my rod and reels in the truck bed when i launched the boat and ran out to the flats, then reaching for a rod to throw at some tailing reds.
Running back to the ramp and hoping no one noticed them back there.

I would never do that

I never left my boat key at house

[boscoe99]

I never left my boat key in Georgia when I drove to Florida to use my boat that was kept down there.

That's my story and I'm sticking to it.

Roughly where might you live in GA? Or is it top secret?
