The Under-Mount kit will arrive mostly pre-assembled and ready to install . The Top-Mount model comes with the cradle arms already bolted in the pivot-brackets and its installation is covered in the video, so it isn't illustrated or explained on this page. However, if installing the Top-Mount model, you will want to use these same principles.

Installation is easy and simple. Use these steps as guidelines, adapting them to your swim platform and PWC or Dinghy.

To prevent dropping any hardware or parts in the water, we suggest you place a flotation pad under your work area so it catches any items that are dropped.

Step 1 is to decide how far apart to space your arms. It is better to think of their placement in terms of the hull shape. We suggest the forward arm be located 6 to 10 inches from where the hull flattens, and the rear arm 10 to 12 inches from the aft-end (see photo illustration below). The key is to have the drivers seat (which is the center of gravity) between the davit arms. When you pull your PWC up onto the arms, try to orient it with that spacing on each side, but it is OK if it is off a little.

Depending on the width of your boat, you will probably want your PWC centered on the swim platform. But because of the bow curve, that doesn’t necessarily mean that the cradle arms will be centered.

Now that you have an approximate measurement, map it under your platform making sure there is no interference with a swim ladder or any other existing features on or under your platform. The angle brackets provided with the kit is slotted to allow for a little adjustment relative to thinner and thicker swim platforms. Dry-fit the mounting arms under your platform to make sure everything lines up and will mount properly. Once a location is chosen, mark that location with tape or a dry erase marker on the upper side of your platform to show the center of the cradle arms.

This next step will insure that you drill the holes so they match the brackets perfectly. Turn the mount upside down so that it will appear as if you are mounting it on the top of the deck as shown in the bottom-left illustration. You can apply masking tape on the top deck to prevent scratching. Allow ¼ inch of clearance on the face of the platform so that the bracket arms will not rub when raised and lowered.

Place one of the angle brackets against the arm and drill the first hole. Insert a bolt through the bracket to hold it in place. With the arm lined up and firmly against that first bracket, repeat this step for the other brackets and holes. Once all four holes are drilled you will be ready to bolt your arms under the platform.

If your deck is such that you don't want any moisture entering its inner core, we recommend using marine grade sealant under the head of the bolts and on the underside to prevent water from entering the core of your platform .

You are now ready to mount the cradle arms. They are directional so be sure to refer to the drawing in the box.

You are now ready to adjust the support arms in the slotted sections of the angle. They should be level and as low as possible but with a little clearance (about 1/4") so as not to not contact the platform. Hand tighten so you can make the necessary height adjustments. When satisfied, tighten all the nuts. You have successfully installed your lift system and you are ready to load your PWC or Dinghy.


You will notice that there is a detent pin attached to the arm with a small cable. While loading, the pin should be placed in the aluminum arm as shown in the top-left image. This will hold the arm at an angle so that you can slide your PWC up on to the arms. If not using a winch or other mechanical pulling method, you might need to pull up the front of your PWC or Dinghy first, then the rear, alternating and tethering, as illustrated in the video.

Once your PWC is up and horizontal, move the pin to the hole that locks the cradle arms level. We suggest securing it to your deck or transom with rope or strap. Alternately, there are holes on each end of the cradle arms. This allows you to wrap a strap around your PWC to secure it to the arms.


Untie the tethers, remove the locking pin, and gently push your PWC or Dinghy into the water. The cradle arms will automatically rotate and your PWC will slip off. Make sure you have a loose tether still connected so your PWC doesn't float away. If you have a heavy PWC, you can let it down gently by un-winching it.

You can now lower your arms down into the water by releasing the pin. Hold onto one end of the suggested tie down rope that is attached to the cradle arm. Hook the other end of the rope to a hole in the aluminum support. This will allow you to lift up the arms without having to reach down into the water when you are ready to load your PWC or Dinghy. The detent locking pin will automatically snap itself into the support arm.

Safety notes:

1. NEVER drive your boat with the arms down in the water at any speed...not even idling.

2. NEVER raise or lower your outdrives while the arms are under water.
