Sweet spot

[PhilPB]

During today's cruise I decided to pay closer attention to speed, rpms & fuel. Mind you this is very unscientific but I think my sweet spot is 1900 rpms, which depending on wind will move us about 8-9 knots and I figure a little over 2 gallon/hr on Perkins T6.354 165hp. Not too bad except on a hot day like today (93°f) a little faster would have been a bit more comfortable.

Also add engine temp stayed around 170-175°f and oil pressure 70 psi at 1900 rpm.

Looks like pretty good numbers to me.
