It appears to be a common trait across a few of their boat models - you could even see it when watching the Big Angry Fish television program.

With regards to solving it - no personal experience, but I do recall one chap having success with installing a Permatrim - type attachment. 

A set of trim tabs, i expect, would also largely solve your trim problems.

Another approach - which should also help with the lack of 'get up and go' - would be to move to a 4 bladed S/S propeller. Broadly speaking these offer more efficiency - and 4 blades specifically, will have more blade area for initial push and typically more stern lift than your factory supplied propeller.
