Engine Control Conversion

The hynautic system is normally pretty reliable.

i m pretty sure the sea star KE4 is the same and the older Morse electronic controls. I used them a while back on 70 footer and they were pretty good over the 8 years I ran that boat. I only had one issue, twice, of course while docking on Fairhaven MA…, it was caused the cable between the servo and the gear. A mechanic had moved it which resulted in too much friction forcing the servo off line. Second time was going thru Woods Hole with its massive current. Fun on one engine

another benefit is that they don’t have any delay.

Is it worth replacing the Hynautic? Not so sure

I had my Hynautic system rebuilt and lines flushed and I am a year in and very pleased. The cost was approximately 12,000. Much easier, smoother action on the gears and throttles.

I would always choose a mechanical setup over flying by wire.

What’s driving the considered change ??

To each his or her own. A poorly functioning electronic control is going to give you fits beyond your present recognition of frustration. Best is to simply have your current system actually restored and dialed in. The systems use o-rings and seals and check valves, and they don't hold up forever, but restored and properly set up they are quite reliable.

A Striker I ran ages ago had Hynautic and there was always a second or two delay changing gears but I suspect it was the transmissions not the controls. Once purchased 4 electronic conversion boxes & all new cables on previous boat but 3 of the 4 were fried when lightning hit a boat a couple houses away. Current boat has Hynautic and working fine. Personally I prefer to avoid electronic controls & would only consider them if a mechanical back up was available or on small boat that never ventured far from home.
