I'd like to replace the impeller in the lower unit of my Searay 2016 Mercruiser Alpha One Gen 2. When I look at the kits that are available on Amazon and other sites, there are different gasket shapes and different numbers of gaskets and plates. I'm having problems selecting the correct kit that would include a new housing. How do I determine which one I need? Or are extra gaskets/plates included to adapt to all situations? Right now, the boat is at a vacation home 100 miles away, and I won't be able to get there for a couple of weeks to take it apart and look to see what's there. Thanks!
