Increasing Wiper degree of sweep

It seemed like the degree of sweep on the 25 was not covering as much of the window as it could. Looking at the manual for the wipers I find that they are adjustable . 60-65-80-110 degrees. I pulled one of the motors.(Remove the wiper arm and 3/4" nut plus the other bolt and nyloc nut) On the back is a sticker that indicated that it was set to 80 degrees.

I removed the 6 screws and the back plate and changed the setting to 110. This involves removing three small screws and rotating a small metal disk so that the 110 is the chosen number.

Put it all back together and not the wiper rests against the rubber when in park and sweeps to with-in an inch or two of the other side when activated. Much better coverage. The second one only took about 10 minutes.

I know that C-dory puts the same motor and arm on all the boats now, so maybe the reason they use the 80 degree is so they only have to carry one motor. Probably the smaller boats don't have as large windshield glass.

I should also probably add that I upgraded the wiper arms themselves from the single spring loaded arm to the double articulated arm. The newer arm which is now installed on all C-Dorys, may have something to do with the sweep.

That new double arm style wiper is a pantographic set up. Instead of just swinging an arc, the double arm set up moves the blade back and forth on the window with the blade staying vertical and parallel with the two sides of the window, which gives much greater coverage than the traditional systems.

You see pantogrphic set ups on trucks, busses, motorhomes, and other vehicles with large windows.

The mechanical principle would seem to be one where the double arm is functionally a parallelogram, with one arm end doing the back and forth driving and the other arm providing a pivot point on the upper ends. The bottom ends and corners follow suit in forced parallel motion.

I'm assuming, therefore, that they require a different type of motor and leverage system as well as the double arm to achieve the parallel sweep motion, so that converting to them would require complete replacement of the wiper system on each window.

Does anyone know if you must replace the entire system as conjectured above or if a simple arm replacement with a new arm having an extra pivot point is possible?

David-

Thanks for all the additional information. Nice installation directions!

Here's a few sources of parts to convert to the pantographic system:

(How do the prices and parts compare with the factory source?)

AFI - Panographic Articulating Wiper Arm
$39.99
Catalog # 196500508

It looks exactly like this one. (The one in the middle of the three sites you listed)

I don't know how much the factory charges because I was having trouble with my port wiper hardly ever keeping contact with the glass so they sent me a new pair.
