I have a yamaha c115 and changed the water pump and everything.Took it out to the lake today ran great.I got back to the boat ramp and notice their were air bubbles coming from the lower unit somewhere.What could it be?The boat ran great though.

most likly its always done it, its exhaust gasses from the prop shaft area.
its rather normal as long as the idle speed and stability is correct.
