Deluxe Boat Launching Dolly, 4 Positions and 4 Stages Removable and Adjustable Legs, 14" Pneumatic Wheels (Silver)

MAX LOAD: This dolly set is designed for boats with solid outboard transom. For easier moving, total weight should not exceed 600 Lbs including boat, outboard, and all gears.

INSTALLATION: This dolly set should only be installed by an adult with some experience in working with tools. To install the wheelset properly, you will need to drill 5/16” holes in the plywood transom for the mounting brackets. It is very important to locate the position of the holes correctly. Please check carefully including checking the wheel arm position before starting to drill any holes.

GUIDELINE OF BRACKET INSTALL ON AN INFLATABLE BOAT- 14FT or Under & with 15" Short Shaft Transom: - (1). Bracket below the transom Top Edge about 1" to 2"; (2). Bracket to the boat pontoon (middle of fabric) about 2" to 2.5”, (3) Make sure the wheel can have at least 1" gap from the boat bottom when at straight down position.

- 14ft and Up with 20" Long Shaft Transom: - (1). Bracket below the transom Top Edge about 2" to 4"; (2). Bracket to the boat pontoon (middle of fabric) about 2" to 2.5”, (3) Make sure the wheel can have at least 2" to 3" gap from the boat bottom when at straight down position.

MAINTENANCE: Wash it after using it from saltwater or sandy beach. Check tire pressure before every use. Don’t store the wheels under the sun or beside the heat to maximize their lifetime. Take the wheel arm off from the transom bracket when storing your boat. Lube the spring load dolly system if needed. Always keep the lock pin on the dolly bracket.

TIRE INFLATION: Dolly tires may not be fully inflated when shipping; please only give 15-20 PSI pressure at room temperature before using. Best to use a car tire digital air pump to prevent tire over-inflation. Tire over-inflated will cause damage and the warranty is not covered.

MORE ADJUSTABLE FEATURES: These wheels have 4 adjustment positions for length and angle to adjust the leg length, push in the spring-loaded buttons on each side of the leg, and either pull or push to lengthen or shorten. To adjust the leg angle, push down on the spring-loaded bar near the top of the leg assembly, and move the leg assembly to the desired location. To remove the leg assembly from the bracket, pull out the quick-release pin located at the top of the leg assembly

3D DESIGN WITH MILITARY QUALITY: Now it is our 2nd edition released in 2019. Seamax Deluxe Boat Launching Wheels system is made by marine grade T6 aluminum alloy with CNC processing and shiny-looking anodized coating against corrosion. Thus, the product is good for saltwater use. Small parts are all made by solid stainless steel and reinforced Nylon. The air-filled tire is lab-tested (1000 LBS), and is great to support a MAX loading of 600 LBS in all conditions. A great add-on for inflatable, aluminum, and fiberglass boats.

BENEFIT OF USE - With the 4 stages of length and 4 wheel-arm positions, the dolly can be adjusted while afloat in the boat, leaving or coming into the dock.  The dolly system can also bring different performance positions for boat launching. The wheel arm length increment is 2.5” per stage. Plus, the wheel’s diameter, range of length is 23 - 30 inches
