- 450 DA Sundancer running CAT 3126
The data above was taken at different times, and under different conditions, mostly smooth seas.
The data below was taken with smooth seas, but taken at ONE time only, and was incrementally done in 100 RPM increments.
50% fuel and 50% water with full tabs.
At this load factor the sweet spot is higher than the anticipated "2150" number I was previously assuming.
At the 50% load factor 2300 seems to be the magic number for this boat, which also goes along with the "sound" and the "feel" at that RPM - feels like the engine is not working as hard as at 2000-2200 range.
Next time I fill up for fuel and water I'll do the same test to see the difference fully loaded, which will likely yield a different story.
BEST !
