This posting summarizes a thread from the WorldCat forum. I think this is a very important topic. It will also be posted in the Safety forum.
Given the potential for hydraulic steering systems to fail and potentially create a situation in which a vessel cannot be navigated, some simple, but important precautions should be taken.
1. always check your connections and make sure they use Loctite so they are less likely to vibrate lose.
2. Carry a steering shaft stopper kit made of PVC pipe as described below
3. For long trips, carry a steering system repair kit as described below
STEERING SHAFT STOPPER KIT:
Ingredients:
1. 1" PVC pipe - approx 10 inches per engine
2. Stainless steel band hose clamps
To make the stops: (see attached picture)
1. Center your ram steering cylinders. Measure chrome exposed on each side.
2. Cut the PVC tubing into lengths equal to the exposed chrome shaft (2 pieces per engine)
3. Cut each piece lengthwise twice removing about 3/8 inch or enough to fit the tube over your metal shaft.
4. Cut a vee notch at one end on each piece.
5. Slide the PVC over the chrome shafts to check for proper fit and minimal play
To use the stops:
Place the stops on the steering shafts and secure with stainless steel band clamps.
You will have to steer using differential thrust assuming you have two engines.
Do not turn the steering wheel when testing this system.
This systems is obviously best for twin engine cats as they can be steered using differential thrust. If you have suggestions for single engine crafts, please post them.
STEERING REPAIR KIT
1. Proper hydraulic fluid for your system (i.e. 5606 Sea Star fluid), enough to refill the system.
2. Engine oil - 1 gal (can be used in place of hydraulic fluid in an emergency and leaks slower)
(1 gal portable fuel tanks, walled with funnel hose are useful for storing the fluids)
3. New vent cap & O-ring
4. Adjustable wrench to tighten fittings
5. Needle nose vise grip pliers inside several oily zip lock bags
I have never actually had to do this on the water, but imagine making repairs could be dangerous in high seas, so be careful and wear your PFD when working on this stuff.
