Merc smartcraft question

[carolina]

Hi just looking for some answers and advice on if and how these gauges work together? My smartcraft info is working great but my mph. Is not ?? Thank you for your time and help, Matt
I did plug in the system link to the mph. Thanks

this may/not apply. my 2004 smart craft on a 200xs required a nmea 2.0 and a speed sentence that matched xxx.cc . the cc on newer gps use a 4 . .cccc number. i'm using a garmin 45 and a street pilot mono, this output the correct speed sentence.

Also depends on where he's picking up the speed info.... if there is no GPS on the boat, then it's taken from the pitot sensor on the engine. Most of the time, the pitot hole in the lower unit gets clogged (on leading edge above the bullet) or someone forgot to hook up the speedo hose last time the lower unit was put on.

Ok ty I definitely have my homework to do on this new to me technology lol. Can y'all explain to me this part and feel free to elaborate more on this ... Due to my lack of knowledge lol. Thanks again guys.

dont know about the part is. on gps you need to ensure that its outputting nmea x.xx [depending on the need by the smartcraft system usually 2.0+.] . also be sure you are using a gps and not an antenna. a lot of people confuse the two. the antenna inputs to the gps [like a tv antenna]. they can both look like a computer mouse.

if that part is actually a digital pressure sensor, then the speed accuracy as equal tp pilot tube speedo [ not to good] and the avg mpg will be off. like wise the digital trim sensor is very slow to read on the SC guage. i went back to the on analog system.

im sorry. it took a lot of work to finally get the 2004 SC working. i got little help from merc and the deal didnt know a lot [he was a freind]. if you would like to talk feel free to call 206 369 3596.

Ok ty, so if I install a nmea 2k starter kit build a backbone will my lowrance gps unit communicate mph to the Merc smartcraft mph gauge? Thanks. Please don't laugh at my lack of knowledge to hard lol

you first need to contact merc and determine what nmea version you need for your system and the format of the speed sentence needed.

with that info you can find a gps the outputs the correct info.

i would hope that from 2004 to today that mercury should have that info.
