Unfortunately OMC stuff is hard to find, check craigslist frequently and by all means ask around lots of stuff laying around in somebodys garage. How bad is the crack? I have seen that JB weld material do some pretty wild repairs on thing you would never expect it to repair. With the season comming to a close soon, can you get by with a temp fix on it? If I were this close to end of season I would certainly give it some consideration. Also check the " I-BOATS" boating forum as they have been extremely helpfull in solving my boating problems.
