- 5.0 Mercruiser w/Bravo III
After replacing some electronics, see my last post in this thread, I have the option to log all data from my nmea2000 network. The smartcraft data is connect with a Mercury Gateway. To analyze the data, is still a bit a hassle, as the standard excel output is general showing data important for sailingboats. But the program supplied with the nmea2000 recorder gives the option to export to XML OpenSkipper.org format. Approx 10k records are saved every minute from different devices.
Besides some technical data and forum posting 'what is your top speed, fuel consumption, etc', had only some info from old test http://www.boattest.com/oem/32/boats/288/0/#Test-Result . But not same transmission, so different prop. (I have Bravo III / 22P)
It wasn't my intention to use the data for analyzing, as the trip was just for fun. But here are some first findings:
I took an average, based on similar RPM during one time frame. In general the trim was 25% or 2.5, trim tabs not connect to network yet.
Seastate was calm. (3 adults + 1 10 year old). Water 50%. Bimini (sides removed)
My data is also limited due to the fact that 70% of the trip was inland sea (current).
During my holiday in July, hope to do specific data runs incl. trim.
