question: Did you need to modify the tank vent to run to both port and stbd? I havent seen too many boats with both sides vented. (check their illustrations)

I have known plenty of folks who have installed Sweetank with only one vent, not port and starboard and had no problems.

A Sweetank works with one vent just fine. The two vent arrangement is for natural air flow through. If you are replacing a tank, I would go with two large vents. If using the existing tank, I would install a Sweetank or make something similar. I put in a Sweetank and it took about 45 minutes to install it. Only hard part was pulling thr trigger to drill a 2 hole in the top of the tank... After 2 hours the stink was gone completely. I did install it when my dock neighbors were gone because the first 2 hours were quite stinky until the aeration was complete.
