Most items now days explicitly instruct you to call the manufacturer and not return the item to the place of purchase. You're asking the LHS to take on an issue and expense that's really not their fault. Their profit margis are pretty narrow as it is. The owner may be of more help, but technically, it's still not their problem. 20 minutes idle time for a 5 pound boat that technically isn't watertight (as long as there's a tube for the shaft, and it's not gasket sealed, it's technically not water tight) is a lot. I hope that you are able to get a resolution to the problems. You went through a lot of hassle and deserve a working boat. Hang in there, the SV is great and it's worth it. Good luck.
