Wow, you really scored a sweet deal. Whoever had that boat before you maintained it well. Looks great.

I have a stainless Duo Prop on my Cobalt runabout. I maintain it to specs and have had zero problems. Cobalt dealer told me just to be sure to use the correct Volvo Penta brand synthetic gear oil in the outdrive. Had it serviced at the place where I store it once. They did not use the VP synthetic gear lube and I could hear the gears whining in the outdrive. Drained it and filled it with the correct VP synthetic and everything was cool again.

Sounds like you and the family are in for some great times.
