Bummer! Doug, the tabs that come on the 210 from the factory are usually Lencos I believe. You can confirm this by looking at the tab arm and the tab switch may have the name on it too. There are different sizes of tabs so you'll have to measure the remaining tab plate to get the dimensions. I would then contact
Lenco Marine about a replacement plate and what screws, etc. will be needed. If by chance the tabs were added after the factory shipment they could be
Bennett Trim Tabs. Bennett has been a great supporter of this website and they are great to work with.
