Have 2023 Chaparral 280 OSX twin 250 V8 Verado's with twin cylinder electric hydraulic steering helm.
Current steering turns is 8 turns lock to lock which is ridiculous. Think about cruising along and there is something you need to steer past and have to make almost a full turn just to clear it. Docking is a joke if steering is attempted. NO Joystick control
Merc install manual list should use a 50CC helm for twin install which should have 6.5 turns L to L. While that's not great, think it would be safer then what I have now
Plan is figure out what helm I can change out to get less turns, or even what would it take to change out to something else that works better

I am getting ready to do a repower to Verados on my old Baja 280 sportfish. While doing a little research, I found that Seastar has a helm that they claim is 4 turns lock to lock. Might want to check that out.

Thanks, Have seen them was hopping someone has done this a few times to be able to advise what is needed.
The Merc install manual list 40cc helm for a single install which will give a 4 turn LtoL. Don't fully understand what is different with twin. There is 2 rams (one on each motor) on the twin, so why does Merc say 50cc instead of maybe 80cc to get a 4 turn. Or maybe a 60cc, might have something to do with the amount of effort to turn the helm, don't know
I have a question out on the Formula forum asking what size they use on the 310.

The pair of Verados that I bought just has one steering ram on the stbd engine and a tiebar that turns the port engine. This was the factory setup on a 34 yellowfin. I wonder if you unhooked one of the steering rams if it would double the turning speed????

Contacted Merc Tech support and they say, contact dealer
Sent email to purchase dealer and so far no response, but then again they are not a repower dealer, also they have been little help so far
No response from formula either
