We think a 2010 was still a plate we bought through Mercury Marine parts and was the third ownership of Detwiler. The pump on the third generation Owned Detwiler was the 125 Mercury trim system and should be easily found.
The SeaStar moved immediately to the same style pump in their manufacture. They also ended marketing through Mercury and went direct. We continue to really like the SeaStar Plate, though support has been dropped on older versions. They just cost too much to service, maintain parts and work on for the cost of a new plate.
