Attwood Outboard Poly Swim Platform with 2-Step Ladder

If you run an outboard and you've ever tried hauling yourself back over the gunwale after a swim, you already know why a transom platform earns its keep. The Attwood 19536 gives you a real step-off, a real handhold, and a ladder that gets you back in the boat without a fight. It's molded from white HDPE, so there's no gelcoat to crack, no metal deck to rust, and nothing that needs varnishing at the end of the season.

The plate measures 23-1/2 inches long by 11-1/4 inches wide and mounts at a 10-degree angle off the transom. That angle matters. It kicks the standing surface slightly downward and outboard, which keeps it clear of the lower unit and gives you a flatter place to plant a wet foot. This is a single-side platform designed to sit next to an outboard, not a full-width swim deck, so it's a good fit for center consoles, tin boats, aluminum fishing rigs, and smaller runabouts where you just need one clean boarding point.

The 2-step telescoping ladder is the part you'll use every time. It stows up under the platform out of the way, then drops down into the water when you need it. Two steps is enough to get a knee up onto the platform from chest-deep water, and the telescoping design means it isn't hanging down catching weeds or drag while you run. The left-side steel wraparound rail gives you something to grab on the way up, which is exactly when you want a handhold, one hand on the rail and one on the platform edge and you're aboard.

A word on fitment, because this is a semi-universal part and it pays to plan the install. It's built for single-outboard transoms, and on most of those it drops right in. On hulls with a lot of deadrise, or where the factory swim platform inserts don't line up, you may end up drilling fresh mounting holes into the transom, so measure twice and seal every hole properly. HDPE is tough but it does flex, so we tell folks to run backing plates behind all four mount points if you're going to have bigger adults using it. That spreads the load and keeps the plate from oil-canning under weight.

Watch your outboard trim, too. If you tuck the motor all the way up past about 75 degrees, the retracted ladder can bind against the lower unit on some setups. A couple of small stop blocks solve it. And check that left-side rail against your fuel line and rigging routing before you commit to the bolt pattern, since on some bigger outboard installs the rail wants to sit right where a line runs. None of this is unusual for a transom accessory, it's just the kind of thing worth sorting on the dock instead of in the water.

Upkeep is about as easy as it gets. White HDPE will pick up exhaust soot behind an outboard over a season, so a wipe-down with a marine cleaner a few times a year keeps it looking sharp. The ladder steps and the steel rail rinse clean with fresh water. There's no wood to rot, no gelcoat to chalk, and no anodizing to wear through.

Attwood has been building marine gear for over a hundred years, and this platform is a straightforward piece of that catalog, one job, done simply. If you want a durable, low-maintenance boarding platform and ladder for an outboard boat, and you're realistic about it being a one-side unit rather than a full swim deck, the 19536 is an honest choice. Just budget a little install time to do the mounting right, and it'll get you in and out of the water for years.
