Featuring marine-grade T6 aluminum alloy construction, 14" air-filled tires tested to 1000 lbs, and a fully adjustable 4-stage length and dual-angle wheel arm system, it offers unmatched versatility and durability. Quick-release pins and spring-loaded locks enable fast, secure adjustments, while a compact transom bracket ensures easy installation on a wide range of boats. Backed by a 2-year warranty, this dolly is engineered for professional-grade boat launching performance. ## Description ADJUSTABLE DESIGN: 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.Our new tires are now 12” in diameter and about 4” wide. They are made of 4 ply reinforced vehicle grade natural rubber which holds up well against UV rays, heat and salt water for up to ten years 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. MAINTENANCE: Wash it after using it from saltwater or sandy beach. Check tire pressure before every using. Don’t store the wheels under the sun or beside the heat to maximize its 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. 14" Dual wheel upgrade kit is available for this Deluxe boat launching wheelset for heavy loading application or sandy beach use. We suggest the boat 14ft and up to use this upgrade kit, then you can have a wide enough transom to support 4 wheels operation. ## Features - Designed by Seamax and now it is the 2nd edition released in 2019. Seamax Deluxe Boat Launching Wheels system is made by the marine grade T6 aluminum alloy with CNC processing and shiny looking anodized coating against the 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 condition. - BENEFIT of its new design - With the 4 stages of length and 4 wheel arm position, 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, the range of length is 23 - 30 inches. It is a great add-on for inflatable, aluminum and fiberglass boats. - The wheel arm has 60° and 90° locking position to move up and down. The upper-60° position can free up more space on the top and side of the transom. The lower 60° position lets the wheels run at the same level as the prop, and thus turns the wheels as a prop guard when boat launching. - The transom bracket installation area is about 8 x 3 inches. Shorter transom bracket design brings more possible installation for all type of boats with different transom. The brackets can be installed at the waterline top position, so to avoid the water comes into the screw holes. We had developed a profile for the transom bracket in 2019. Now the bracket only requires 2 bolts to install. Easier to put it on your boat with the same loading capacity. - TRIPLE heavy duty, TRIPLE quality made! Product is made by Seamax Canada with 2 years limited warranty and 100% Customer Satisfaction guaranteed! The Quick Operation Features of the Deluxe Boat Dolly include - spring load locking pin for wheel arm position adjustment; solid spring load buttons for wheel arm length adjustment; and quick released lock pin for wheel arm and wheel bearing. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Seamax | | Model Number | Deluxe Boat Wheels | | Color | Sliver | | Product Dimensions | 30.5 x 40.6 x 61 cm; 7.26 kg | | Maximum Weight Capacity | 600 Pounds | | Material | Aluminum | | Special Features | Adjustable, Heavy-Duty, Warranty | | Item Weight | 7.26 Kilograms | ## Product Details - **Product dimensions:** 30.5D x 40.6W x 61H centimeters - **Brand:** Seamax - **Material:** Aluminum - **Colour:** Sliver - **Special features:** Adjustable, Heavy-Duty, Warranty ## Images ![Seamax Deluxe 4 by 4 Boat Launching Dolly with 14" Wheels System, Commercial Grade Quality for Inflatable Boat and Aluminum Boat Max Loading 600Lb - Image 1](https://m.media-amazon.com/images/I/61HKzgZY1yL.jpg) ## Questions & Answers **Q: Are the wheels red or black? and are they 12" or 16"?** A: I received mine on April 11th, 2021; the rims are black and the tires are 14 inch. See my review for photos. Hope this helps. **Q: Please tell me if there are problems keeping the tires inflated and if a replacement tub/tire can be purchased . Also how hard is it to operate thee raising and lowering of the wheels and can they be used as you get close to shore in the down position to make sure your wood boat bottom will have limited wear and tear. …** A: Hi Cheryl, This is a very well made product! I am not sure what transom you plan on mounting this on, but I have an inflatable Achilles 12ft boat. I load everything including 115lb outboard and sometimes take the boat down some pretty rough paths to get to the water. I need something that won't break while going over branches, mud, etc. Then, when you get to the lake, just raise the wheels. They will lock upright in 2 different positions. Just take your time while determining where to mount them the brackets on your boat, the directions are good. You shouldn't pull your boat with your vehicle; not sure why you would be worried about the hub or tire. They should last for years. Check air once a season; like all tires, they tend to needing slight filling once a year. Very simple to raise and lower; spring loaded slots. And yes, pull the lock pin on each wheel and you can remove them. I am very critical on alot of poor Amercian engineering and spent alot of my life repairing things. I like the best in what I buy and would recommend this highly to you. You won't find any better. Enjoy! **Q: Anybody try these on soft sand? with a loaded boat that is... me personally it will be with an 10.5 foot inflatable with 10hp motor. thanks!** A: Works great on my 11 foot inflatable with 10 hp outboard. Not sure what "loaded boat" means. My experience is with a total weight of roughly 140 lbs. The more weight, the more difficult it will be to move over sand. For my purposes, this is a very well constructed, strong product if installed correctly. Took me roughy an hour to install. Very easy to do. **Q: Hola. Por que dice envío gratis y cuando lo voy a pagar me cobran el envío?** A: free shipping when you are prime member of Amazon and shipping with USA or Canada. ## Frequently Bought Together - Seamax Deluxe 4 by 4 Boat Launching Dolly with 14" Wheels System, Commercial Grade Quality for Inflatable Boat and Aluminum Boat Max Loading 600Lb - 3M Marine Adhesive Sealant Fast Cure 5200 (05220) Permanent Bonding and Sealing for Boats and RVs Above and Below the Waterline Waterproof Repair, White, 3 fl oz Tube --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/272127365-seamax-deluxe-4-by-4-boat-launching-dolly-with-14](https://www.desertcart.co.th/products/272127365-seamax-deluxe-4-by-4-boat-launching-dolly-with-14) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-02*
