Helm Displacement

[Dock Walker]

I cannot find an answer for this with Garmin or on the inter webs. My Garmin GPS went to setup mode for some strange reason and going through it is asking for helm displacement. I am not familiar with that and do not know where to look for the answer. It’s a 2016 25SC.
I completely shut off all power and restarted hoping it would reboot and be happy but no.

Info on the web says the helm displacement is typically marked somewhere on the helm itself, generally it is located in the location where the hydraulic hoses connect at the back of the helm.
Your gps needs the information for your auto pilot. Hope this helps! More info on the web but you will have to search for it. Bob

The helm displacement on my 2012 R27 is 1.7 cubic inches. I’d bet your R25SC is the same.

Hi Dock Walker,

CaspersCruiser has it right. Your helm pump is a 1.7l unit. You can usually look up the data on the label (if visible) but just in case, that should be an UP28FM pump. Hope this helps.

Thanks,

Ralf
