Hello iBoats! This is my first post, so if it's in the wrong place please let me know.
I recently purchased a 15hp short shaft outboard for my 14' soft bottomed inflatable. The motor has been working well, but I've found that as I increased the throttle (and speed of the motor/boat), the boat rises ('on a plane'?) and the prop begins to come out of the water. Presumably without any water resistance, the motor revs high and isn't pushing against anything to move the boat forward.
Here is a short video showing what I mean: https://vid.me/G2TKb
And here are some photos of the boat transom and outboard: http://imgur.com/a/B3G6Q
I'm new to boating and outboards -- I tried to do some research and thought that a short shaft would be right for this transom (~15.5 inches high), and I know the outboard angle can be adjusted (though I think I have it set to the 'lowest' setting, as close to perpendicular to the transom as possible; the problem seemed worse when it was one 'notch' higher).
Looking for advice: this isn't normal, right? Are there any other adjustments I can make to the outboard? Do I need a long shaft motor for this transom / boat?
Thanks for the help!
