Default Why no engine sync'ing?

My aircraft experience is showing with this question......

Why is there no engine syncronization system (to my knowledge) available on today's multi-engine boats? I can understand the need for separate throttle control for docking/maneuvering, but once underway and running it would seem that having one throttle (engine) as the "master" and the other throttle (engine) as the "slave" would be an advantage as only one throttle would have to be manipulated. I can understand how "back-in-the-day" the cost to implement such would be prohibative. But with todays digital engine management systems I would think the feature would be relatively easy to include.

Thoughts??

They are available and more common on bigger boats.

I don't know why their not used on go-fast. I would like to have synchronizers on my boat. Anybody know why their not used on go-fast?

They're available from simple stuff like a gauge to make it easier to do, all the way to automated single lever control. They're just not typically used on the hi-po stuff we love around here. Maybe that's the real question.

Big in the cruiser\yacht market......a google should turn up a lot of systems, but you'll see they're aimed at bigger (and slower) pleasure boats.

Clarification......(sorry)

I meant why we don't see it (digital auto throttle sync'ing) on todays' premium go-fast boats.

tda3,
I always thought dual engine boats should have an aviation style tach that you see on piston twins. One head with dual needles. That way all you do is put one needle on top of the other and then you know the engines are synched.

What is youe aviation background?

Agreed, would be a good idea. Some people have a good ear for sync'ing twins. I remember dialing in my boat with Tres Martin several years ago, first thing he told me was drive gauge was off costing me speed. Adjusted trim to compensate and picked up three MPH.
