Just completed replacing the port side windshield wiper motor on my 2014 CW30s. This is a challenging job. It took me about 6 hours of four letter words. I am posting this as a help to make your repair shorter if you do it. My first advice is don’t do it. Have a professional do it. My disclaimer is that this is my experience and should not necessarily be complete instructions.
With that said I was too cheap to go that route. Here are thoughts.
The placement of the motor is very challenging under the eyebrow of the boat. To access the motor take the cover off the speaker. A slight turn counter clockwise will do it. Four screws to loosen the speaker. Mark on the speaker which wire goes on which post and put aside.
In the hole of the speaker you will see the motor. Do not at this point clip the wires. The motor has 4 wires. Hot wire for port side slow, hot wire for port side fast, black wire for park and brown for ground. The motor is connected to the fiberglass with a screw and nylon nut and the shaft from the motor with a nut on the outside. This is where it gets tricky. There is not much room in the hole plus you must remove the pantograph wiper arm ( the working side only, not the lazy side). This is a challenge as there is very little clearance between the windshield and the grip for the wiper arm. It is like a battery terminal. I had to spray PB lock loosener several times. Make sure you put shop towels up to catch spray. Then you take two screw drivers and ‘coax” the terminal off the motor shaft. Took me nearly an hour. No need to take the lazy arm off. A terminal puller does not have enough clearance to get into the tight space. Then wiggle the heck out of the motor to get it to come out of the hole where the shaft is.
Once off, carefully look at the wires from the motor and where they go on boat wires. The newer model of the Roca (Imtra) was marked ok, not on the original. Boat wires were clearly labeled. Carefully read instructions with your new W12 motor. Carefully look at the setting inside the motor compartment for the park setting and the length of the wipe. Duplicate those settings on the new motor. Complete wiring and reinstall the way it came out. You will need a ratchet wrench and a ratchet with an Allen wrench (I think 5mm) it is the only way to reach the bolt to put the terminal back on. Using an Allen wrench alone is a waste of time. Not enough torque.
On my boat I had to unattach the” fast wiper sweep wire” from both the port and starboard as they share a park fuse. Not sure why.
Follow the instructions to set the park and sweep size. The shaft of the motor has red marking as it lines up with the part of the shaft that you run the nut on. Do not get these two red lines out of line with each other or you will create issues.
Reassemble speaker cover and 6 hours later, open a cold one
