Can use Mercury Smartcraft Tach/Speedo on older Mercury engines
I own a 2001 Mercury 250 EFI Outborder and smartcraft is not supported
I'm looking for a nice paddlewheel speedo (up to 70 km/h) and the Smartcraft looks really good.
There is no real need for me to use additional functions beside the speedo (and eventually tachometer).
Does any owner of that instrumentation know, if it's possible to use the instruments only for these 2 functions? Speedo should be "standalone", beeing only connected to power and the paddlewheel sensor, the tachometer only needs the spark signal ...
Is it possible, to calibrate the analog display to measure in km/h?
Is it possible, to see the actual speed in the digital display and is it accurate enough on acceleration?
Thanks a lot
PS: Perhaps you know any other paddle wheel instruments. By now I own a Raymarine ST40 which is to slow (display update only once a second).
