wood floor inflatables won't plane when powered by engines up to their rated hp, they are not designed to. You need at least an air floor for any hope of planing and at least twice the hp of that little Honda. I messed about once in West Marines little rollup with a 3hp Seagul and got nowhere near a plane. On the other hand, a 4hp on an inflatable bottom dink will plane nicely with two fit and trim adults.
"Their flat bottoms and small engines (up to 4HP) make their performance non–planing, limiting their range to in–harbor, relatively flat–water travel."
Now I have been able to get my WB 8 "on step" with 3.5HP (1.5 more than it is rated for). That was a frightening experience I will not soon repeat.
EDIT: captainjimbolio, If you can get your 260 on step with a 2hp I want video!!! Put it on Youtube right away
