Slip/cavitation

[Nick725]

Hi went out today on a 3m waveline with inflatable v floor, it also has built in trim tabs at rear. It has a yam 8 hp standard shaft on the back. As soon as we got her up on the plane the prop lost grip, but im unsure why. Anyone have any advice. The floor was pumped with a hand pump, meamed fine but was not checked with a pressure gauge.

Air floor SIBs can be prone to this... but... without knowing the floor is up to pressure you aren't giving it a fair chance... you need a gauge!
