I am putting this out there in the event any Carver owners have similar issues with their Volvo Penta electronic throttles.

I have a 2006 Carver 44 CMY that is fitted with Volvo Penta D6 Diesel's that are controlled by the Volvo Penta electronic throttles.

I was on plane running across Georgian Bay at 3100-3200 rpms. I noticed a siginificant RPM drop on my starboard engine. The starboard throttle is the slave and sync's with the port. When I moved the throttle forward slightly the RPM's would return to the RPM's of the port side. This would continue to occur periodically.

During the same trip I was running in the channels at about 1200 RPM's and I did not have an issue. However, I have noticed while running at idle speed during locking/docking, that the same throttle will not engage the transmission when I throttle up from neutral to the #1 position. If it tap the throttle forward slightly it seems to engage the transmission at that point. This makes me believe it is not a fuel flow issue. This is also supported by the fact that my EVC does not register a fuel flow issue, as it normally would.

I was thinking about switching the wiring between Port and Starboard to see if the issue transferred from side to side, however, it is not occurring all the time and cannot be predicted.

Has anyone had this issue, and if so, what did you do to remedy the situation. I am all ears.
