If rigging a boat with twin E-TEC G2 150-HP engines, can the steering be configured as follows:

--the standard rotation engine has Dynamic Power Steering (DPS)

--the counter rotation engine has the TRACK-PLUS non-steering mount

--the two engines are linked by a conventional mechanical tie-bar

--the DPS engine steers both engines.

Rigging as described above would save weight and cost, and would still provide DPS steering for twin engines. Since the DPS mount is capable for steering a 300-HP engine, I would assume it could handle twin 150-UP engines.  

Does Evinrude permit or endorse this rigging for 150-HP twin E-TEC G2 rigging?

Does the DPS engine have a connection point for a tiebar?

yes.

I believe the issue with having one engine with DPS and one with conventional Trac steering is one is going to be setback 3-4 inches more than the other. The setback engine would be getting "disturbed" water from the other. The boat might be off level because of the leveraging affect of the seyback engine wrt the Trac engine. The positions of the tie docking points may not align properly etc

Muskie mouth is is correct. The dps mid section is the version with the 4in set back. The Trac midsection is the same midsection as the original E-etc. no setback.
So the setbacks alone create different mounting height issues such plus different fore and aft alignment issues.
The G2 tie bar kits include brackets to be installed on the engines. The trac mid section cannot accomodate this bracket.
Reminder - the trac mid section is designed to use the typicical seastar type of external steering cylinder.
One dps midsection can easily steer 2 engines.

Based on the comments, you'd have to get one engine with DPS and one engine with integral steering and no DPS, use the tie bar, and connect the two hydraulic systems together with the usual T-connectors. Please comment on that idea.

ALSO: what happens if you want to add iDOCK? Do you need DPS on both engines?

that is the idea, non of the counter rotating engines have power steering.

The new idock requires specials engines that have a unique engine code, not sure what is different.

I dock would need dps on both. Much like other joystick or unilever systems I assume the engines use an electronic tiebar system by virtue of position feedback sensors to keep them synchronized when being used to steer conventionally. The helm unit in these is electronic rather than hydraulic.

Hi,
This excerpt from Evinrude’s own literature,
Quote
“iDock leverages the exclusive internal steering system of Evinrude E-TEC G2, keeping your steering pump protected, your transom clean, and your compartments free for storage.”
Refer http://www.evinrude.com/en-US/idock.html

Cheers

I don't think that the helm steering wheel with iDock operates with electrical output. That would be quite unusual. I suspect it works with normal hydraulic output.

All iDock literature is a bit sparse at the moment. But I would expect that when iDock was engaged, there is some hydraulic valve operation that allows independent movement of the engines, but by hydraulic pressure. DPS works on hydraulic input.

If the main helm steering wheel relied on iDock to generate the hydraulic pressure, the entire steering system would fail if the iDock pump failed. That would be a problem. As far as I know--based on Evinrude's literature--the ability to steer manually is always present.
