Going to have to agree with everyone.....and add a few.
When your stuff breaks and they ALL do/will the odds of both O/B's going at the same time is really low. Wait 'til you bust that sterndrive 25 miles from nowhere with the single I/O.
No more "heavy" winterizing.
No more crawling around in the bilge!
No more noise police.
Keeps the mosquitos away............
