I have a Raymarine Type 3 linear hydraulic system and I need to refill the hydraulic fluid. However, Raymaine does not seem to have a specification anywhere that I can find for the type/grade of fluid to use.
Location: Western Caribbean & ocassionaly inCanada
Boat: Mesqua Ukee, Buccaneer 40 (Salar 40)
I have used ATF fluid for years (18,000 miles) in my type 3 pump. Keeps things simple, it's the same stuff as in the transmission. Keeps the inventory of lubricants simple, should you have a catastropic leak somewhere.
