Hydraulic Steering on 88 Mercury 200

Post by jasongrms » Feb 13, 2018 7:59 pm

I want to upgrade my steering on my 1988 voyager from cable to hydraulic. It has a 1988 Mercury 200 Blackmax hanging off of the back. Seastar can't give me any direction on what cylinder I need for this engine since their catalog only goes back to 1989. I would think there would not be much difference, if any, from the 88 Merc to the 89 Merc but I am not sure. Is anyone out there running hydraulic steering on this particular engine model? Just Looking for some direction on what cylinder/system will work. These systems are expensive and I don't want to buy a system only to find out it will not work. Any input would be much appreciated!

According to Seastar's PDF, the cylinder required is the same.

http://www.seastarsolutions.com/wp-cont ... 001-21.pdf

page 27 (of 122)

Cylinder: HC5345-3

And since they list multiple engine mfgr's using the same cylinder, with no options for different mounting plates, I think its safe to assume that the mounting bolt patterns are standardized.

Thanks AdamDK! The Seastar tech support guy was directing me to the Seastar Pro series (HC6345-3), so I didn't look any further. Thanks again for pointing this out!

Ya, running above 60/65mph will require the Pro or Tournament series.
