I have a 2003 GTX. It does NOT have a boarding step.
I would like to add one.
Who has added a boarding step?
What brand?
Do you like it?
Does it leak?
How difficult is the installation?
Is it strong enough for a 250lb person to use?
I just installed a boarding step on my GTI. Aquaproducts.com. They're not cheap but it's a quality product and works well. It's also BRP original equipment.
I just installed an aqua step on my 96GTI. It's not cheap but it's well built, it's now easy to board my ski. I bought it directly from the manufacturer their website is www.aquaperformance.com
It's also original equipment for BRP. If you decide to buy one from EBay make sure it has the correct hardware.
