Like the 235, the O'Day 240 also has a stern cut-out for engine, or pass-through to swimming if you haven't an engine. Do any other trailerable boats share this feature? Of course you may respond here, but an email to me, at dux28@earthlink.net would be much appreciated. Earthlink has a firewall called Spamblocker, but worry not, I'll get the email. Thanks again.
