Glad I could help I had another lock we had used and it was ruined by the end of the trip. It wasn't brass. The one I linked to I haven't used yet, but I have an identical one (shorter opening though) that we've used two summers out all season long on cape cod and its been great. Used one on the dinghy engine and one on the engine on the boat to lock them on and they both have held up great. That's why I got this one - same thing, but larger opening - we'll be bringing it next trip.
