Default Raymarine ev-100 with Seastar Hydraulic Steering

According to the EV-100 SPECS of the type .05 pump are: 3.1–9 ci or 50-150cc.

and the Seastar cylinder (5358,5345) having 8.34 ci or 136.6cc capacities.

It should work just fine correct? What am I missing ?

I, too, am curious about this. When I researched this some months ago I swear I read that the pump specs wouldn't work with the average Seastar cylinder. If, in fact, it does work, then this will most likely be my AP.

I just set one up with a 5345 cylinder on my boat. Works great so far (about 14 hrs pilot run time).

Corey,

Looks like the pump needs to be sized to the steering system. Here's a link to options:

Subscribed. I had the S1000 on my World Cat for six years. Had one pump failure within warranty period, other than that it worked OK for a $1k unit. I am interested it putting a Evolution pilot in my Proline/Verado and am waiting to see how/if the EV100 works for others. I'd rather spend $1500 instead of $2500.

yeah, that's the whole point of this thread -- to get some real world data on using the 100 with a common Seastar system. This question has been bounced around for quite some time because, as you show, the pump specs and the Seastar specs don't exactly match. Yet most of us find it hard to believe that Raymarine built an autopilot for a seastar cylinder that would be found on, say, a 70hp engine as opposed to the cylinder that a major percentage of the boating population uses. And we also have seen on here where certain people have actually installed the 100 on their boat and have reported zero issues, albeit they all have limited hours on the system so far.

So, if we can get real feedback from the people who have actually done this install, it might put our minds at ease to go ahead and purchase it. The appeal is the price, of course. But once you jump to the EV200 then you might as well shop every other brand out there. For the cheaper price of the 100, I'll gladly give up the seamless integration with my Garmin system. But if I'm shopping the 200, then I might as well just get the Garmin so that the AP and my 5212 are extra-cozy.

EV100 is problematic on some boats. The usage and boat size in addition to RAM size have to be taken into account. Slow trolling at less than two knots in a 20' boat in rough weather can be extremely demanding for the pilot.

From another thread:

had to replace it with type 1 pump and Acu 200.

I guess we need to include the requiements of users to better qualify AP choices. My requirement is for the AP to steer my frickin' boat in a straight line at cruise speed for 30 miles.

?? Those are the volume requirements. If I were in the market for a new AP, I would check existing equipment specs, call Sea Star to verify my findings and order the appropriate AP system. If the EV100 is borderline too small, I wouldn't even consider it.

peterSnow, got any experience with the EV100 installs on single 225 Verado w/Mercury power steering?

Topmotor so far is Suzuki 250 on Seastar steering. But it all depends on the ramcapacity of your steering system. As long as it is within the specs. - i would go EV100.

Thanks, got a reply from a local Raymarine shop, they say Mercury Verado power steering is within the EV100 specs. I am still a little hesitant in the decision. Looking for more real life feedback.

No matter what Evolution AP you choose. Just make sure you get the rotary knob display ( P70R). Steering the boat with the knob is just awesome...

Sooooo, even though the Verado power steering specs are within the EV100 spec, Mercury recommends the EV200. Per my local Raymarine dealer and Mercury tech support.

Gotta put some more $$ in the piggy bank...

Put another 9 hours on the Ev-100 today so it's up to a total of about 23 hours run time. All good. My typical usage is an hour run out, troll all day at 4-5.5 knts, hour run home.
