what does prop slippage actually feel like? When I'm running full trim and wot. it sometimes feels like the engine is misfiring. It doesnt feel this way at 3/4 trim and wot. Is this slippage. Also, my prop is kind of nicked up on the edge of the blades from previous owner. nothing major just small rough edges. It's a 4 blade Stainless. Would a new prop help? thanks all.
