Question All Prop...?

No trim tabs
Whale tail on the outdrive
Prop pitch unknown at the time of this post
Is this the 130HP engine? I'll ask a friend with an older Glastron 19.

Great "little" boat, BTW. (Though its five feet longer than the runabout that got us into slalom skiing with only only 20HP). Gets through culverts, tiny passages, and under Wolfeboro's Smith River Bridge to Wolfeboro's secret, available, and empty Town docks.

It sounds like a prop-inefficiency "at speed".

Damaged blade? Corrosion covering the aluminum? New prop, but inefficient pitch?
