ADDING POWER STEERING TO Hynautic Hydraulic Steering System

[JACKPOT]

Has anyone added power steering or power assist to their Hynautic hydraulic steering system?

Sort of.
We added a Teleflex power steering system, but the helm was already from Kobelt.
Hydraulic pump on the engine, power assist ram, different reservoir, a cooler, some additional lines, and you're good to go.
There's lots of different ways to end up with power steering today, many are less complicated than what we did, depending on the application.

Bottom line is it's a really great upgrade.

Accusteer (owned by kobelt) makes a powersteering pump that senses helm movement and provides assist. I think it can also be controlled by an autopilot. Was about $2k from what I recall.

Question is ... why would you need power steering on a 43?

Why not?
Sorry couldn't help myself, have the 12volt Teleflex/Seastar electric assisit pump that senses helm output (probably similar to Accusteer) and then adds pressure to the rams on our center console which has twin 300hp outboards.
I've scene the same set up on a few sportfish boats including the Good Grief, a Hatteras 46 repowered with CAT C15's. There may be photos here on the forum from their refurb'/repower.
Teleflex/Seastar also has a higher end all electric hydraulic pump package that uses the same ram as the engine pump system that most of the bigger boats are now getting when built.

Thank you guys, Cricket your on the stick, I too have it my 31 Pursuit CC, boy once you use it ...its like candy. That is precisely the set up I am going to replicate with the same Sea Star power assist pump. However, I wanted to check here first.... prior to my endeavors. Thank you all for your input.

Best,

The boats I've seen with the DC power assist pump all had them mounted pretty close to the the ram, not sure there's a reason or not for the placement. On our CC the pump is right under the helm. My first thought is to keep the power wire as short as possible and to also make sure it's properly sized. Good luck with the project, let us know how it works out, think many are missing out on power steering benefits.

You got it Cricket, will do.

Well, you guys have got me thinking.
I would love power steering, I wonder how much I would spend by the time I'm actually finished with the project?
It's always 200% more than you think....and Murphy was an optimist.....

Steering efforts on 53 and 58 are pretty low so until you hit 60/65 why bother?

Luckydave, if I was adding power steering o day I would look into this system first. Far less hoses/pieces/parts, no on engine hydraulic pumps to add, no oil coolers to add, etc.

Looks like the trend is to fly by wire helms etc, not sure if I'm quite ready for that although the install has to be even simpler as the only hydraulic lines are from the pump to the ram..........

There's other options, know the Teleflex/Seastar stuff the best. Love Kobelt's products for their high quality, we have a Kobelt helm and also their push/pull engine controls.

Finally got Benedetto out after two months of work. Third time I’ve run the boat since purchase. The one thing that stood out was how effortlessly she made a 180 turn at 18kts. Easier to steer then our 20’ Grady with a single 150.

You keep doing that you ain't goin' nowhere.......

Furuno has a system that works with Accu-steer pump, but requires furuno autopilot. The Furuno FPS8 module bolts onto the pump. It has two flow sensos (connected to the autopilot brain) that measure manual wheel movement and adds assistance with the pump.

When on autopilot, it also can sense manual wheel movement and temp disables the AP.
