CAVITATION
Cavitation should not be confused with a sheared propellor pin.
Wise words 😯
My late friend, John Dertinger of Delhi ON, Cdn outboard racing champion,
was/is still known in FL AOMC circles for his ‘Eskimo motors’,
ie; OK-15 & 20s, which he would sell, and pay for his winter vacations .
Folk there still ask me if I brought any down ?
We had a number of them as kids in the ’60s, blew them up on Mini-Max’s,
and by using too little oil. We thought the OK-20 was the racing version,
becase it had 4 stud detachable heads.
