What’s Included in the Stern Saver Transducer Mounting System Kit?

The kit contents are as follows:

• One High Density Polyethylene (StarBoard) block

• One two-part adhesive containing static mixing syringe

• One mounting spike

• One mounting template

• Four alcohol prep pads

• One piece of sandpaper

• One pair of rubber gloves

• One instruction booklet


Can the Stern Saver be removed in the future?

Yes, but not that easily. It must be cut off with a thin kerf pull saw found at most hardware stores for $30 or less. Since the bond between the Stern Saver and your boat is supposed to be permanent, it is not supposed to be removed. It should be though of as a permanent extension of the boat. If you must remove the Stern Saver from your boat please refer to the removal instructions and purchase a removal shield to protect your boat’s gel coat during removal.

Can the Stern Saver be re-drilled if I want to replace my transducer in the future?

Absolutely. You can either re-use existing holes in the Stern Saver from previous transducers by simply using 3/4″ long or shorter screws of a larger diameter than the previous screws. For example, if you previously had a device mounted using a 3/4″ #8 screw, then upsize to a 3/4″ #6 screw. If you do not want to re-use existing holes you can also just move the new mounting location to the left or right an inch of so.

What can I mount to a Stern Saver?

The Stern Saver was originally designed to provide a mounting surface for sonar transducers. It has also proven useful as a mount for many other devices such as bilge pumps, live well pumps, fuel separators, battery switches and more. The Stern Saver is not to be used to mount grab rails, any structural or heavy devices over 5 pounds.

How does it work?

You first determine where you are going to install your transducer of accessory. Then you clean and prep the area of the hull. Load the Stern Saver with adhesive, stick it on the boat, and secure it in place with masking tape. After 4-6 hours you are ready to mount your transducer or accessory using a 3/4″ or shorter self-tapping stainless steel screws.

I thought StarBoard or polyethylene plastic cannot be bonded to anything using adhesives?

Not any more. At Stern Saver, we have ‘cracked the code’ on bonding polyethylene to surfaces like gel coat, aluminum and more. Our patent pending design, as well as our specially formulated marine adhesive ensures a permanent bond to your boats hull. We use the highest quality adhesive available on Earth. We do not supply a lanyard with our product like some of our competitors do. We are confident that when installed properly, your Stern Saver will offer years of reliable use.
