My boat has a Mercmonitor kit 79-8m0135536 installed, but no sensor for speed. The gauge is wired directly to the engine via CAN with no junction boxes. Are any good GPS antennas available to work with it? I don't want to add an additional screen and it doesn't have a GPS right now. There's nothing connected to the NMEA cable. The engine is a 2008 250 ProXS. 1B690561 Thanks!
You don't have any graphs on this Bass Boat?
I have a bass boat but this isn't on my bass boat. Is that against the rules here?
No, I don't have a bass boat either (see sig pic).

I think it would be easier and more useful to install a graph with GPS and mapping than to get GPS hooked up to the MercMonitor. Not sure what good GPS is if you can't navigate the lake for hazards, etc.

Agree.Originally Posted by Bob G.
The Mercmonitor has a bunch of features that don't work without speed info enabled. Looks like Lowrance makes a few NMEA 2000 based GPS antennas that look promising - but I didn't want to buy one without getting confirmation. I'm going to check with them directly. No screens for this boat.
Get a Lowrance Point 1 antenna.
This is what I would do mainly because I know it would work and I am familiar with it. You will also need a basic NMEA network...2 terminating resistors, a T for the Mercmonitor, another for the Point1 plus however many drop chords you need to span the distance to all the items. The Mercmonitor will power the network so no need for running wires or installing a switch.

Yep do that.
That will work. Just be careful to use a reasonably high-grade NMEA-2000 based GPS antenna. Mercury offers the components to do this, but what you have proposed will work just as well.
