   Looking for some help. I have a 1997 Luhrs 360SX that had Volvo TAMD 63 P's in it, 370 HP each. I recently repowered with a pair of Yanmar 6LYE-EPTs at 480 HP. I'm wondering if anyone has the same boat with the Yanmars and if so, what are your performance numbers (cruise and WOT) and what Prop size do you have?

   Yanmars may have a higher RPM operating range.
   Did you change reduction or props during your upgrade?
