I have a complete new Teleflex "SeaStar 1 " internal hydraulic steering system here with a first generation surface & behind dash mounted helm pump, inboard-style 1 1/4" diameter aluminum cylinder, swivel cylinder mount & rod end heim joint, black plastic lines & special compression fittings etc.
I also have several bottles of the older red SeaStar fluid & rebuilding kits for both helm & cylinder + air bleeding kit!
I bought three of these "Seatar 1" inboard systems for several restoration projects we had here about 25 years ago~~~
The "SeaStar 1" was just introducd at this time !
We used two systems on standard conventional inboards & rudders with geat success.
These were used on classic mahogany speedboat restorations Dad & I did.
We hid the helms under the older original steering bezels along with making a steering wheel adapter..
The third complete system I still have today was never used !
I think this system cost about $700. ~~~Twenty years ago !
How well would this "SeaStar 1" system work with an old original Volvo-Penta 270-280 out drive ?
This should easily replace the old Teleflex push-pull cable steering system I would think ?.
Would this give me a more stable steering system ?
How about at Donzi 18 top speeds ?
I like the fact that the steering systems actually locks with internal check valves when you stop turning the steering wheel and let go of it !
I know it's not really a true racing system~~~
But would it work very well for speeds up to say 65 MPH ?
How do I tell what the Cubic Inch output is of this New Old Stock helm pump ?
I know they made several helm pump outputs.
I believe this is the lowest ?
Is there a part # on this helm that would tell me it's output capacity lock-to lock ?
Has anyone actually used a "SeaStar 1" internal hydraulic steering system on an old Volvo 270-280 powered Donzi 18 ?
If so~~~
How well does it work on an I/O Donzi at higher speeds ?
