raymarine hydraulic pump installation quotation

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.

The Hydraulic oil in a steering system will always contain microscopic air bubbles, these will coalesce and create larger air bubbles over a period of time and will then lead to cavitation within the pump - causing loss of pressure as well as creating excessive noise and possible overheating. It could also lead to the shaft oil seal running dry, hardening and then subsequently leaking.

In addition to the above, the thrust bearing of the pump is not designed to operate in this orientation and will wear excessively leading to possible premature failure.

We would always recommend the pump is mounted with it"s axis horizontal, with the pipe connections exiting at the top, (so do not mount horizontally with the pipes exiting the pump body from the side) . Mounting the pump so that the pipes are connected to the top of the pump body will allow any air built up inside the pump to be expelled back to the reservoir and not interfere with the operation of the pump.

I need to replace the wheel drive on my ST4000. The old unit could no react quickly enough with my existing hydraulic steering. Would replacement with Type 1 hydraulic pump be a possible fix, system is 5 turns lock to lock. The boat is full keel with a barn door rudder, 43ft 15 tons.

The steering has the pump and reservoir at the helm but with only two lines leading out to a manifold which supplies the two steering rams. Could the reservoir inlet at the pump be ignored?

The diagram shown within the hydraulic pump installation guide is not intending to imply that the Ts should be installed within the middle of the hydraulic lines. As indicated within the installation guide, performance will be maximized when the pump has been located within close proximity to the steering ram. Installation would typically require that the hydraulic hose be cut to permit the T to be inserted. Many Raymarine dealers (ex. The GPS Store, etc.) offer offers fittings kits to install autopilot hydraulic pumps to various types of hydraulic steering systems. While Raymarine does not produce them, it is conceivable that T fittings could be installed directly to the ram itself.

Unfortunately, the S1000"s course computer is exclusively designed for use with the Type 0.5 Pump which had been packaged with S1000 autopilot. Moving to a hydraulic autopilot pump having greater capacity will require that the autopilot be changed. While it is quite possible that a Type 1 Hydraulic Pump may be proper for the new outboard"s steering system, the required model of hydraulic pump will ultimately be determined by the outboard steering ram"s cubic capacity. If supplied with this information, then the appropriate autopilot hydraulic pump and corresponding Evolution Autopilot System Pack may be specified.

A search of the Internet yielded the following, but it is recommended that this be verified with Evinrude"s support team: G2 is 8.9 cu in displacement. If so, then a Type 1 Hydraulic Pump would indeed be recommended. The T70330 EV-150 Hydraulic Autopilot System Pack includes the pump, Evolution Autopilot Components, and networking component required to interface the Evolution Autopilot Components to one another. An E22158 SeaTalk1 to SeaTalkng Converter Kit may be used to interface the C80 MFD to the backbone used to interface the Evolution autopilot components to one another.

In order to meet the requirements for the installation in the manual, I had to place the hydraulic pump and the reservoir further away from each other than I would have liked, and also with a tighter turn than I would have liked. This has resulted in a small kink in the hose coming out of the pump heading to the reservoir.

In looking it over I think I will be best served in the long term by replacing this hose to make sure the Hydraulic Fluid supply is running clear and without any kink. I am looking now to have a replacement hose made, one that will (1) exit the pump with a fitting / hook up that has a 90 degree turn to fix the kink and (2) is slightly longer - about 1 ft - than the original to accommodate a needed turn to get to the reservoir.

+ Is there a part name or specification for the fittings / hook ups on either end of the hose (Pump >> Reservoir and vice versa) so that when I have the hose made I can specify the right hook ups on the end of the hoses to interface with the pump and the reservoir respectively.

A. It is indeed not hard to bleed the hydraulic steering system. Good vessel maintenance would include regular replacement of the fluids and lubricants within the vessel"s engine(s), steering, and hydraulic system. When replacing the pump, this would indeed be a good time to replace the fluid within the hydraulic steering system. There are a number of good videos on YouTube addressing how to change out and then bleed the steering system. The Bleeding the system section of Chapter 5. Post-installation check of the Hydraulic Pump Installation Guide calls for following the instruction of the hydraulic helm manufacturer when bleeding the hydraulic steering system and that afterwards follow the additional instructions provided within this section of the Hydraulic Pump Installation Guide.

My cost effective comment should have been clarified. The total cost of the installation is dependant upon the boat in question and what, if anything, needs to be changed. My comment on cost effectiveness pertained to the autopilot and its installation only. A mechanical actuation for cable steering is expensive, but with hydraulic steering it usually just means a hydraulic pump installation and no mechanical hook up other than T"s in the hydrauliuc lines and the rudder feedback sender.

How effective an a/p is on fuel economy is pretty much dependant upon whether your a/p is speed proportional or not. I notice that some guys in our marina who opted for the lower priced Raymarine model when they added their a/p"s zig-zag all over the place as the a/p continually over corrects at cruise speeds or at fast idle, depending upon how the installer set the gain. I just won"t follow one of them.
