Hello all, recently purchased an xb03. By no means new to performance boating, but I am new to owning an Allison. My boat has a stock 20” F block 2.5 200 with a coned 200 lower.. Whoever coned the lower unit did a shotty job and the epoxy/bondo is beginning to chip off. So my question is what would be my best lower unit to replace what I currently have with? My foot can be repaired but would rather replace at this time. Thanks!
