Add to your existing Gullsweep® for those applications when a Gullsweep® could fall off of a non-permanent mounting — i.e., GS-RK pulled from a canopy might turn sideways and the Gullsweep® could slide off the center mounting pin and go over board. Unfortunately, Gullsweeps® do not float or fly.
Simple to install and will take the worry out of the situation.
The retainer is to prevent a Gullsweep® from falling off the center mounting pin and being lost overboard. The retainer does not have to be used for Gullsweep's ® proper operation. Gullsweeps® have been used for over 40 years without a retainer. However, today there are many more mounting options and a mounting pin can possibly shift in heavy winds due to a loose mounting or with the rotational vibrations that Gullsweep® generates.
Gullsweep® does not fly as they do not have any lifting component; and they do not float either. A retainer is not only for peace of mind but can prevent a lost Gullsweep® in that unforeseen situation.
To install, slip retainer spring up on center mounting pin. Put Gullsweep® on mounting pin and press all the way down so it is resting on the center pin. Adjust the retainer spring so it is in place over the hub retainer ring with a minimum 1/8" clearance above the hub retainer. The spring should not touch the hub or the retainer ring. (See diagram).
To remove, pull back top of retainer spring so Gullsweep® can be removed. Spring retainer can stay on the mounting pin, however the pin should be removed as it can be dangerous to anyone on the boat.
