Restoring the upright support and comfort of your favorite three-person sofa towable is a seamless process with the high-performance 3 Rider "Super Mable" Style Backrest Replacement Innertube from TRL Watersports, LLC.
- You should always maintain a steady towing speed between 15 and 20 mph to ensure the backrest provides the proper aerodynamic lift and rider stability.
- These boat tube replacements feature a high-flow Boston valve that makes it easy to adjust air pressure on the fly for a firmer or softer ride.
- You will find that using a tow rope with at least 3,350-pound break strength is essential for safely pulling three riders across the wake.
Don't throw away that perfectly good towable cover, re-use it! TRL Watersports original replacement innertubes are quite simply the strongest in the business. This is a bladder replacement for models like the Sportsstuff® “Super Mable”, Airhead® “Pit Stop” and Gladiator “Super Brawler” 3-person towable tube BACKREST ONLY.

- Utilizing these towable tube replacements allows you to keep the rider’s center of gravity stable, which prevents the tube from nose-diving during low-speed starts.
- You can trust these boat innertube replacements to hold their shape during "S-turns," which are the best way to give riders a thrill without crossing dangerous wakes.
- Having these boat innertubes properly inflated ensures the outer nylon shell remains tight, reducing the water drag that can strain your boat’s engine and tow pylon.
