The kit can be installed by anyone handy with tools.
The biggest issue is cutting the hole in the deck for the mast. We have a kit listed in the catalog "99600001 Install tools" that gives you a hole saw and a special locator guide (fits in the existing mast hole). The rest is simple I think.
Send me an email and I will return a pdf of the instruction. It is a simple text document with just a few small images.
