I headed out yesterday to a local anchorage and my old girl ran great (2 454,s 7.4 340 hp. But on the way back they ran fine cruising at 1500 rpm hull speed, but when I increased the rpms to get her on a plane 2800 to 3200 she started to miss like she was going to quit. I dropped back down to cruising speed and they ran fine again. On returning to the marina I booked her in for a tune, hope is a simple fix and not a valve or something, any ideas guys?
