Author Topic:   E-TEC 90 Trim Gauge on I-Command System

I bought a new 2008 E-TEC 90 and installed the I-Command system [with dial pointer gauges]. I found that the engine management module (EMM) on the E-TEC 90 doesn't support the trim gauge that I paid $100 for and was supposed to daisy chain into the rest of the system. Nor will it support the trim function in the $400 tachometer, so now I am left with no trim gauge function at all. After discussing this with Evinrude technical support line I am more confused. Evinrude technical support claims I need an additional $100 harness to even run a regular $30 trim gauge, and that this $100-harness would tie in somewhere on the engine. My [rigging tunnel] is crowded already and I don't know if I can squeeze another harness thru it.

After spending several hundred dollars on six different I-Command harness pieces I still don't have a trim gauge function. Needless to say I am very [upset] and disappointed. If the sending unit is a standard OMC sending unit and not special for the I-Command system--which I don't know--what prevents me from just running a 12 volt supply to the gauge and running a single wire to the sending unit and then to ground? I would just disconnect the sending unit from the motor harness and treat it as a separate standard trim gauge with a standard sending unit. I think this would work but would welcome opinions if this is flawed thinking.

What have others done regarding trim gauges on E-TEC 90 motors?

I don't have a trim gauge on my e-tec 90 on my Montauk. I thought about it but I can trim by the tach, speedo, or sound. I didn't want to cut another hole in the console.

When an '08 90 is equipped with I-command, the first thing to do before initial start is to put the laptop on it with BRP's diagnostic software, and set your upper and lower trim limits. Did you have this done? The trim level can be displayed on your single LMS-400 tach, no need for a separate trim gauge, unless you really want one.

The other thing the software asks you is where does the engine live? If you choose "single engine", it automatically defaults it to port, even though you have a standard rotation motor. But the computer is necessary, along with the software.

Thanks seabob4.

But I don't believe I have an LMS_400 tach.

Mine is the I-Command classic tach p/n 763406.
It does have a display for trim percentage but that is blank.

BRP tech support told me that on the 90 hp only this function is not supported by the EMM ,only on larger motors. Some kind of misdirected cost savings. With all the confusing info I have received I can only hope they are wrong on this too.
I would gladly pay a few more bucks to have it functional and avoid the hassle of trying to fit a trim gauge.

If you are correct and that function can be activated I would be very happy but it sounds as if you are talking about a different tach.

Anybody else have any thoughts on this.

Your dealer did not tell you about the inline motors not having a trim function?

What is easily done it to use the original boat wiring harness with a tradional trim gauge. You don't need the special I-Command harness that the V-4 and V-6 motors use.

1) Seahorse is correct about trim not being supported by I-Command on the smaller motors. You can set up the helm with a separate trim gauge as that function is part of the standard engine harness. 2) Sorry about the reference to the LMS-400. That IS the gauge you have, as it is the Lowrance nomenclature for that gauge. I-Command and Suzukis SMIS both use the identical gauges and NMEA 2000 parts (tees, termination resistors, backbone harnesses, etc.) made by Lowrance.

Did you get a manual explaining all the features of the system that are available to you?

You mention the standard engine harness. I don't know what you consider the Standard engine harness.
I have the I-Command ignition/trim harness p/n763542. Also have the EMM to power hub harness p/n 763541 and some other shorter pieces from the power hub .

Are any of these what you refer to as the standard engine harness?
If so, where do I plug in the trim gauge?

Yes, I did get the booklet about I-Command and have a factory manual with wiring diagram on order. My dealer has never installed any I-Command system and seems to know even less about them than I do so they are not much help.

In addition they botched the paperwork for my special 5 year warranty that was offered in the spring . Calling BRP they say my motor is not registered for any 5 year warranty and talk to the dealer. The dealer doesn't know what to do.
BRP says it is too late!!! Some customer service!

Anyway , tomorrow I am going to beautiful Lake Tahoe to forget about my motor problems for a couple of weeks. Will return to this thread when back if somebody has any additional thoughts.
In the meantime ,
Thanks for your inputs.
