Self Centering Boat Trailer Roller Kit | 700mm Wing, 6in Roller

A self centering boat trailer roller kit for the retrieve, not another loose keel roller. Wind or tide walks a tinnie off the centre rollers. This Load Ya Boat wing catches the hull and guides the keel back onto the centre roller while you winch, so you are not standing in the water pushing the bow straight.

It is the Wind Ya Boat setup: one galvanised winged bracket with stainless rivets, a 700 mm arm and a 6 inch roller. Two adjustable legs, with bolts and lock nuts, set the height and the angle so the wing sits just under the hull. It suits 19 mm double-stem roller brackets. Stated fit is aluminium boats to 5 m (16.5 ft).

In the box

• 1 x Load Ya Boat winged bracket, galvanised, stainless rivets
• 700 mm arm span and 6 inch roller
• 2 x adjustable legs, bolts and lock nuts
• Guide skids for the wing
• Suits 19 mm brackets

Not in this kit: 50 x 50 mm tube sliders, a second wing, a clamp-on adjuster, or the maker’s Teflon-lined aluminium skids. Those aluminium skids are a separate part. If the trailer is 2 x 2 inch box steel and has no 19 mm stem, use the self centering boat trailer roller kit with 2x2 tube sliders ($270).

Which kit

• This page: winch-on, one wing, trailer already has 19 mm double stems.
• Single-stem brackets: add a clamp-on adjuster. The wing will not bolt into a single stem.
• Drive-on: fit a second wing on the next cross member. One wing is the winch kit.
• 50 x 50 mm box and no 19 mm stem: buy the 2x2 tube slider kit, not this one.
• Telwater frames are often 75 x 75 mm. Measure the cross tube before you order.

Install

Boat off the trailer. Tyres in the driveway, or the ramp car park if you can get it back on. Free the old roller bracket with penetrant first. Hammer only if it is seized, grinder if the bolts will not move. Sit the wing arms in the 19 mm adjusters. Boat back on. Set the height to the existing rollers, grease the threads, then lock the second nut. If you are fitting skids, let them stick out past the rear of the trailer so they catch a boat that comes in offline. About an hour with a shifter and a socket set.

A self centering keel roller is one grooved wheel. It helps after the keel has already found it. This kit is the guide in front of that roller. Use both if the centre roller is flat-spotted. The 8 inch red self centering roller is listed separately.

Maker fit note: adjustable legs cover most Australian tinnie trailers, alloy hulls to 5 m. Not the kit for a large glass boat.
