I am not familiar with NMEA2000 - compatible, but I can research it

Something like this is probably the easiest to adapt.

I need stroke range, probably need a custom cable so it is long enough to get to a junction box.

But it is a start

I hope to have to installed in my scarab in the next couple months!

With regards to other ideas. What about a gas gauge that was ale to display accurate fuel level regardless of boat attitude! I think it can be done with three senders in the tank (one at the front, one in the middle and one at the back). With a little bit of math the program should be able to calculate the exact fluid level in the tank by averaging the three senders and displaying that level on the gauge!
Theoretically, this is a good alternative for fuel level. Hydrostatic technology uses the weight of the fluid above the sensor to calibrate the volume of fluid in the vessel. Need to do a little more research as to weather the motion of the boat will throw it off, but it already throws off the floats anyway....

These measure down to an inch or less of fluid all the way to thousands of feet deep.

Chip detector for your outdrive oil, and engine oil. We run them in the airplanes, they save lots of money and in some cases lives.

Heres one that could be adapted for boating:

Why not add AFR as well? I think someone should make an O2 sensor bung in a dry joint clam strap that adds an inch to total exhaust length, no welding. You could do that and add a relative humidity sensor for water in the same strap
Water level is tough, but humidity can be done with a hygrometer mounted before the water mixes into the exhaust. Getting the signal out may be tricky, but could be done. This data would not be very cheap

It could also be linked to the ignition so that if the circuit is closed, ignition to the engine is cut instantaneously. Just like an oil pressure switch. I think these would be VERY effective at saving people lots of money with a gear failure in your outdrive.

Any of these signals can be linked to guages or simple digital displays, but they would fill up the dash.

The idea is to use ruggedized 19" touch screen HMI's and program them with virtual guages to show read outs of everything being monitored

What kind of money are you talking if somebody wanted just standard stuff. Oil/water pres+temp, boost, etc....

I have been watching these guys for a couple years now! Some neat products and they support NMEA!!

Most k-planes and drive cables have a 3 inch stroke. I need to find out what these cost!! I will do some digging and post what I find!
