I am very happy with the kit, it is much better than crawling under a wet boat to hook up the Fake-a-lake. 1.25" is the size kit. If you order at skidim.com, just talk to the guys there and tell them your boat and model,they seem to know what you need.

A sharp razor knife (cutting hose in 2 places), screw driver (for the clamps), and wire cutters (wire inside stock hose) are the tools that you need.
