Will I dock be available on the 150 at some point? I have a cat and would like to eliminate the liquid tie bar. Optimus EPS would work but it's pricey.

It’s already available on the 150HO.

iDock is not available on the 3-cylinder 150 HP that just came out, only on the V6 150 HO models and larger.

Ok thank you. Do you happen to know if I did twin I3 150's with DPS on my cat would both motors have an integrated steering cylinder?

The I3 engines are capable of being ordered with tiller, standard cable or standard external hydraulic steering or DPS.  With a Catamaran, I'd assume you'd need a hydraulic tiebar steering setup which would mean your starboard engine would be a DPS model and port engine would be a simple hydraulic model (follows the starboard engine via hydraulic hose tiebar).

If you went with 150 66 degree V6 engines, you could have I-dock models installed.  Is weight your primary consideration?

Weight is not an issue and I really don't need I dock but I like the idea of not having a liquid tie bar. My current seastar cylinders, liquid tie bar , hoses and helm are original and twenty years old. So when I repower I would also need to replace those parts. So if I went with I dock i would only need new hoses and new helm. If I went with DPS I would need helm,hoses and tie bar. If I went with Trac steering I would need to replace the entire current seastar system. Is that accurate?

An alternative to the Optimus 360 Joystick system is called "Optimus". This is an identical steering helm and cables from the helm to the transom (as O360), uses the same external steering cylinders with a steering position sensor and only one hydraulic assist pump. And it is usually about half the price of O360 joystick.
It works really well on catamaran boats of all sizes. Think of this as an electric or digital tie bar. The steering sensors always keep the engine aligned. No more messing with the alignment valve.

All Evinrude iDock installs require the installation of a liquid tie bar. Optimus would be the only way to eliminate it.

A liquid tie bar is not needed with iDock as the electronics determine and maintain the engine alignment.

Continuing with Seahorse's post. Steering position sensors on each engine along with the engine EMM and the iDock control modual contstantly monitor and maintain engine alignment as it was calibrated to on initial setup.

Please refer the the iDock installation manual.

Below is a diagram out of the manual, note the hoses between the two engines and alignment valve.  This setup is also known as a liquid tie bar.  When NOT in iDock mode hydraulic fluid flows through this liquid tie bar to steer the engines.  The way the DPS works is that when turning starboard only the port engines power steering pump turns on steering both engine by pushing fluid through the liquid tie bar.  And when turning port that same thing happens with the starboard engine engine pushing fluid the other way through the liquid tie bar.

When steering with the Joystick in iDock mode then all of the boats hydraulics are locked out and all steering is done integrally by each engines midsection.

In the iDock system the alignment valve is only used when bleeding the hydraulic system. It is true that the toe is adjusted electronically by the iDock system but the physical liquid tie bar is definitely still required.



Also to note that some catamarans require the standard and counter rotation engines are reversed to handle properly.  This configuration is not supported by iDock, so i would double check your engine orientation before any more consideration is made for iDock.  The left hand or counter rotation engine MUST be on the PORT side for idock to function properly.

What manufacturers require the motors be reversed? I've heard some folks claim better fuel economy reversed and I've also heard some folks run 2 standard rotation engines.

I don’t have a list, last year I was at the Miami boat show and took a ride on a cat with Suzuki’s and they were opposite. I believe World Cats ship in standard orientation. I just brought it up as something to confirm because iDock will not work the other way.
