Removed bottom paint from lower unit
 

When I bought the engine for my 20 the previous owner bottom painted the lower unit. I ran it like that for two years and finally got sick of looking at it especially since I just painted the hull. Here is a before and after shot. I wet sanded for 5 hours with 400 grit then primed a few bare metal spots then got some spray paint from the local Yamaha dealer.
