Sorry folks, important data was missing. It's a 4.30 mt Seamax alum floor inflatable powered by a 2 stroke Tohatsu 30 HP which is the max can handle.
-Water flow at speed is passing right under small water deflector plate, ideal height for an inflatable.
-The inflatable bow seems to be too near towards bow, there's water splashes side of bow no matter if an adult or light feather champ sits there.
Trim is spot on, if moved from second hole to first or third hole water performance gets worst. Second is ideal.
-Tubes and keel are inflated to it's max 3.5 psi working pressure.
-Been tested with just 3 adults, that inflatable can carry 7 passengers, engine is undergoing its break in period, the boat planes at 1/3 throttle, at 1/2 throttle the performance is scarry, chine walks like cracy.
-Seems this model is a crappy one, just good for lakes, ponds, rivers, pools, as diving platform, fishing, sipping bears, you name it. Incredible plate bears a Canadian Certifcate. Very near to be returned to dealer along consequent anger...
Will post some pics tomarrow to have a better overall idea of the problem.
Happy Boating
