Engine sounds

[Giantsfan]

I took my 1900 out on Lake Tahoe this weekend. No wind and very few boats. Its a wonderful time of year to get out and enjoy the scenery.
This was my first summer with the boat and I'm wondering about a noise I hear from back of the boat. The best way I can describe it is a gurgling noise, almost like air being sucked in or blown out from the stern drive. Is there any way to tell if this is normal ? Thanks for the help !

well..that really doesn't give us anything to go on??...a sucking noise or gurggling noise is kinda vague.....so....unless the temps go way up...the oil pressure drops or the oil level in the drive drops till the alarm sounds...I wouldn't worry....
