This is my first inboard......have been with outboards for 30 years

When pulling tubers yesterday when I would make a hard turn to starboard......I would hear a rpm surge and it would feel like an outboard prop slip.....best I can describe it...like the beginnings of an outboards prop packing slipping...

Only thing I could think of is that water intakes are to port side of center.....maybe sucking air in??

Temps and oil pressure all looked good.....

Thank u Ina
Advance for your help
