My Tides 27 Express,
OSPREY, had dual station Morse Ke-4 controls for her twin Yanmars. I, as did everyone else who drove
OSPREY,
loved them. They were precise, smooth, and very reliable. I also made sure that manual overrides were available and easily accessible in the event of a power failure. If properly installed, the answers will be "yes" to both of those criteria. A synchronizer is an option, but I stuck to using my ears. Teleflex was a bit slow to respond to my inquiries, but their answers were complete and accurate.
A word of caution: Make sure that
everyone aboard understands the sensitivity of the controls. Even a slight bump of the handles will result in a substantial change in RPM, resulting in unwanted acceleration, deceleration, or shifting. I made sure that everyone on the boat either stayed completely clear of the helm station and tower controls or drove the boat for awhile to familiarize himself.
