New to Hydraulic Steering Systems

**DEN** · 03-20-2019, 06:30 PM

My DIY boat build need a steering setup. A mechanical setup just won't work, I don't have the room for cables.
At speeds above 60 mph, from my research, hydraulic is the only way to go.
I believe to got the cylinder covered (HC 5345) will bolt right up to my Merc.
Its the Helm I am having some understanding with. Research tell that 1.7 cu. in. not good above 60mph.

2.0 vs 2.4
Which one is better, safe at 70-85 mph?
Is there a REAL difference in driving?
Will one turn quicker then the other?
I have read several articles, some mention this, some don't.

(97 Merc 225 hp)

Experienced feedback much appreciated!

I have the 2.0 sea star pro helm and high pressure hoses on my AE-21 works great , 90 mph so far , the 2.0 is the standard sea star pro helm for single engine setups I think.

Thank you! Just what I needed/wanted to hear.
Searched this helm and the ad said 4 -1/4 turns lock to lock...
works for me.
kinda pricey, but then what not when it come to boats.

Thanks gentlemen.

You won't regret it, it is a good unit, make sure to bleed the mess out of it

I've ran the 2.0 with the hc5345 ram in my stv at over 100 for many miles.

Make sure you get the right helm for your boat. Mine runs a dual opposed system, which the right side of the helm hooks to the left side of motor/ cylinder.
