Sounds like the prop hub is slipping

Re: 94 90HP 3 CYLINDER MARINER

The ratcheting is perfectly normal. Prop ventilation can be a problem if there is something that is distrubing water flow at the back of the boat. Did you recently add a transducer or something else to the back of the boat near the center line? To check the prop, put a mark on the hub. Put another mark on the outer part of the prop in-line with the first mark. Run the engine until you notice the problem. If the two lines are no longer lined up, the hub is slipping inside the prop. It needs to be repaired or you need a new prop.
