What's the difference between a rear mount and a front mount helm?
A rear mount helm installs behind the dash for a clean, low-profile look. A front mount helm bolts through the front of the dash.
Does it include a cylinder or hoses?
No. This is the helm only, with elbow fittings. You'll need a SeaStar cylinder, hoses and SeaStar steering fluid, or you can choose a complete SeaStar steering kit.
How many turns lock-to-lock will I get?
It depends on the cylinder you pair it with. Tell us your cylinder and we'll give you the number.
What steering fluid should I use?
SeaStar hydraulic steering fluid only.
