raymarine hydraulic pump installation made in china

The Drive unit is the part that interfaces with your vessel"s steering system to keep you on the right course. Raymarine has a broad range of drive units to match almost any type of steering system - our Evolution Autopilots accommodate hydraulic, mechanical and power assisted stern drive systems.

If you are not sure how to determine what type of steering system is installed on your vessel, please consult an authorized Raymarine dealer or contact us directly by using the form below.

I suspect that if you consulted with Sea Star"s support team, you would find that the two capped ports are for an optional hydraulic fluid reservoir and for the additional hydraulic hose from the autopilot"s hydraulic pump shown within the diagram below.

Should no hydraulic fluid reservoir have been installed with your helm pump, then the helm pump would be acting as a limited capacity reservoir for hydraulic fluid. One of the caps which you have referenced will need to be removed to accommodate connecting the additional hydraulic hose from the autopilot"s hydraulic pump.

Regarding the location of the autopilot"s hydraulic pump, best performance will be achieved when the pump has been located in close proximity to the steering ram. The pump"s installation location should also be protected from exposure to moisture associated with rain and waves. However, it should be noted that it sometimes not practical, particularly in smaller boats, to install the autopilot hydraulic pump in very close proximity to the steering ram. In smaller boats, the location of the autopilot hydraulic pump is less important with respect to the performance of the autopilot. However, it is key to ensure that the autopilot hydraulic pump is located at a lower height relative to the helm pump and that the hose is run in a continuously upward direction from the autopilot hydraulic pump to the helm pump.

Complete your Evolution autopilot system with an autopilot control. The new p70s and p70Rs control heads feature vibrant colour displays and are powered by Raymarine’s intuitive LightHouse user interface.

Control your Evolution Autopilot directly from your Raymarine aSeries, cSeries, eSeries or gS Series multifunction display. Note that your multifunction display must be running Raymarine"s LightHouse II software and that some autopilot functionality may not be available if your system does not include a dedicated autopilot control head.

According to the Sea Ray parts manual, the hydraulic ram is a SeaStar BA150-7ATM (HC5314-3) with a 7" (178mm) stroke and 10.2 cu.in. (167.1cc) volume.

According to the Raymarine selection page here, the Raymarine M81120 12V pump supporting a Ram capacity of 80cc to 230cc is the correct unit. The page shows the M81120 pump is suitable for both the EV-150 & EV-200 systems.

Interested in members" input as to the differences between the EV-150 & EV-200. The EV-150 kit does not come with a M81105 rudder angle reference sensor, so that would have to be purchased. There is an input in the EV-150 ACU to hook up the M81105. Also noted the lack of a clutch output from the ACU, but the M81119 pump does not have a clutch wire so I don"t think this matters. The ACU-150 has a max continuous drive current of 12A vs 15A for the ACU-200, or 25% more VA (not Watts since I don"t know the power factor). Suffice to say more power goes to the pump, so I"m guessing rudder inputs occur more quickly. The ACU-150 does not have a "sleep" output whereas the ACU-200 does. Not sure what that does. According to the old Raymarine forum "a Sleep switch disables the operation of the autopilot while retaining any power supplied to the SeaTalkng bus".

Lastly, can either EV-150 or EV-200 use the pump already in the boat, or is it recommended to change out the pump to the M81120 as well? Both the original pump and the new one have only two wires (A & B) connected to the ACU. TheGPSStore opined that if the OEM pump has low hours (the boat has just over 1000 hours on the engines), then the original pump should be fine. A M81120 pump can always be purchased later, if needed.

After the branch in Xiamen, this is the first Linde Hydraulics plant with extensive production in Asia. Parallel to the expansion of production and installation, a sales and service center was established and opened at the beginning of the year.

The employees at the new plant were specially trained for their new tasks for over one and a half years at the Linde Hydraulics location in Xiamen; further training units were carried out at both the new location in Weifang and in Aschaffenburg. The service, sales and application engineers were also trained by the Linde Hydraulics Training Center in Aschaffenburg.

Sun Shaojun, Executive President of Weichai Power said, “Today’s production start-up marks the beginning of a new journey for the development of Linde Hydraulics’ business in China. We are very pleased to be able to actively assist

Linde Hydraulics in its further steps in the Asian market. I am sure that our joint commitment will enable Linde Hydraulics to fully meet its objectives.”

The new plant will be operated by Linde Hydraulics (China) Co., Ltd, which was formed in a joint venture between Linde Hydraulics GmbH & Co. KG (51%) and Wechai Power Co., Ltd (49%) in March 2015.
