18...and I like it

I think those are worth a try. Appreciate the review.

And where are pics of this Bertram? I love those boats!

I might have a couple somewhere but the ex got most of the photo albums. It was an original '65 Moppie 20 (Hull #223) -still had the curved glass windshield. Repowered with a 290HP small block and a Volvo 290 drive. Guy I sold it to took it to Eleuthera about a month before Andrew leveled the island - guess it's a reef now.

Which info isnt showing up?

[steel686]

I’m getting RPM, fuel flow, miles, volts. Need to set max RPM and I read you need a resistor if you use an analog trim gage at the same time. No oil pressure, trim, etc. Probably can’t zoom the picture very well.

Etecs don't have oil pressure

You sure? I thought they injected the oil in specific areas of the engine and it's not all mixed with the gas. It may not be high pressure like the fuel injectors, however I would think the oil has to be under some pressure. I'll ask my brother how/if his 250HO registers that info on his MFD. Again this is from memory that a BRP dealer/salesman told me at a boat show....I've burnt a bunch of brain cells since then.

E-Tec's have an oil pump with an integrated pressure sensor but it isn't a constraint pressure pump like in a 4-stroke. They use pulses to push oil to points around the engine I assume in coordination with inputs like rpm, fuel flow, etc. I think the oil alarm is linked to rate of actual pulses compared to what the EMM wants. So in a long winded way, I'm saying real-time oil pressure on an E-tec isn't very helpful.

That’s a good point. Just low oil on BRP gage. Only wondering what information EMM drop cable is sending.

I thought the BRP gauge light was for low oil level switch on the reservoir but it could be a pressure indicator. I know I would want a true level indicator (not switch) on the oil tank but I'm kinda picky. It is pretty easy to add NMEA sensors to the backbone.
