      December 10, 2019 at 8:18 pm Simple answer is 100% YES…………………………………… But things need to done right and the process fully understood as to how it all “works” for your ( every ones) unique installation. In so many words, there is no “one size” fit all.. Tony

      August 14, 2019 at 2:22 pm I have a MIKelson Nomad with QSM11s .We run @1200-1300 rpm 95% of the time . which is 5 gal/hr and 91/2 -10 kts. Does it hurt to run this way most of the time? Should I run higher from time to time? It is a displacement hull so more rpms does not yield much more speed, thanks Joe

      August 14, 2019 at 8:41 pm The answer is in the link below and it has not changed, although it should be updated to say “as the the max HP per liter has gone up quite a bit since I wrote this with the new electronic engines , IMO, low speed running to add longevity to an engines life is even more advantageous” -Trust me, your QSM11’s love it…————- Seeing 30,000 + hours over a 10 year year period on QSL9s & QSB 5.9…
