My port side lower unit on my 2018 Evinrude Etec G2 250HO is shot. I have the boat at the dealer processing a warranty claim, but it may take a month or more to fix and I have an offshore trip planned with out of town family for over a year that I am still trying to salvage...looking to buy a counter rotating SLX lower unit that I can use as a spare. Please help if you have one or know where I can find one.
