The barb I was waiting for finally arrived so I got my fuel pump setup.
Made up a plate so I could mount the pump using two bolts instead of relying on one.
Got the boat launched to try it out and immediately had problems. The ground wire for one of the coils had snapped. So 15 minutes later that was fixed, took it out for a blast, was very slow getting on the plane, the all of a sudden the power is just there and it takes off. Couldn't really open it out, bit too windy. Managed 48 knots, not a personal best but not bad for the conditions. Highest RPM I saw on the tach was around 6100, so hopefully there's plenty more in it.
Idling very low just now, need to sort that out first then see how it goes. I'm hoping the acceleration bogging problem can be fixed by changing the carb jets?
