Newer Full hydraulic steering upgrade
I'm working on 28' single engine V-bottom with a older version of hydraulic steering Hynautic is the name of it.
I have removed the entire system and replaced it with Latham Marine rams 2" bore 8" stroke and all new HP lines. I'm running a remote reservoir GM power steering pump and I'm looking for the information on how to select the right steering motor for 4 turns lock to lock. I believe the GM power steering pump is a 6.5 GPM speck and the lines are rated to 6000 PSI.
I just need to know a part number or how to get the right specs on what to look for.
Any information would be greatly appreciated thanks
PS Nobody at Latham is any help

You have 25.13 in³ of fluid per cylinder. (π•r²•H) So, 50.26/4=12.565 you need a helm that is ~12.5 in³ per revolution. That is if your cylinders bottom out not you transom assemblies.

I assume you mean hydraulic helm when you say steering motor?? The chart I posted a link to gives enough info to get real close. Looks like you need either a 100cc or 125cc helm.
