38 Open Cummins performance
#1
Greetings.
Surveyed a sweet 2006 38 Open today... ran well. Anyone known what RPM to Knot chart looks like for the 490 Cummins around 2006 year? Thanks!

I've attached performance data for my 2003 38 Open w/450hp Cummin's. Don't believe there could be much of a difference w/490 Cummin's, maybe a knot or 2 at most.... Suggest you contact Tiara to see if they have performance data for your 38 Open...

I cruise at 2000 rpm's with mine at 24 kts.

Here is the performance cure.
