Replace old style wiper arms with pantographic?

Dear Trawler Forum,

I have a wonderful 1990 Grand Banks 32. It has the old-style windshield wiper arms that just go back and forth and make a semi-circular clear area on the windshield. Does anybody know if it is possible to simply replace the arms with newer-style pantographic wiper arms that would clear a larger area? I don't want to replace the motors, just the arms.

I have posted this same question on the Grand Banks Owners forum, but I suspect more GB owners follow this forum than that one!

Thanks in advance.

Can be done.

The first thing you need is the degrees of sweep your motors are.

I found some wiper distributer that had a calculator for figuring out what you needed on the web.

I have no idea what site, but I doubt it hard to find it or anther guide.

Even with that guide, the actual install took hours of tweaking.

Greetings,
Mr.O. Excellent question. That would be a good upgrade for our boat, even it it's only the port in front of the wheel. Tall port, short arm leaves the bottom 1/2 un-wiped. A pantograph system would be much better than the alternative retrofit...

You need to check the specs on the motor and see if it can drive that big of a blade. Otherwise the pantographic arms are great. Hopefully your motor is able to be set up to park the arm when it is turned off.

Look at some online catalogs , some motors can be used with a single blade and only require the offset pin to be installed to use the pantograph.


If the wiper motor you have is old , really old , a new wiper unit will be adjustable in terms of degrees of sweep, and parking L or R can be selected.

This is an upgrade kit. Turns a standard wiper into a pantograph. You can actually make it work with out adding any new holes to the boat. Comes in two lengths, you will most likely want the 22” model.

You will still get some sweep motion but your field of vision will be more than doubled.

I also have a wiper guy in Oregon who can make true pantograph wipers for any boat for about $400 a window. That does not include installation.
