I recentley recevied a 12 foot fiberglass sears 1979 boat. I bought a honda 9.9 short shaft for it since the rated horsepower is 10. A few days ago i noticed that there were two cracks in the transom and one along the side. What can I use too fix this boat. Or will it be ok to leave it alone. I usually bring it out in the bay and it can get a little rough out there so could this also be the problem. Is there any boats that I can purchase to use with this motor that will peform well in the bay and also be good for fishing. Thanks
