In the last few month this crack has started to "grow" little by little. I can jump on my lower units and the transom does't have any flex. Its a 1991 251 fwc with twin 225 YAMAHA ox66. Should I be concerned?

Always concerned with cracks. You may want to take some steps to at least seal it up. Stop the water penetrations points.

quote:+1. That is the begining signs of a future transom job. I agree with Marc - seal it up as best you can to prevent more damage. I would check your brass scrupper drains for holes, pull motor bolts one at a time and reseal, and check all other penetrations. It seems they used a lot of putty up in that area which does not respond well to any flexing which is why cracks show there first.

Pretty common. I ground my cracks out and glassed over them. They never came back. A few years later I did my transom and found there had to be 1.5 -2" of filler in the top of transom. Filler isn't structural and doesn't flex and it's a sharp corner, bad recipe [

I installed these engines a 1.5 years ago and put a lot of 4200 in the bolts. Also just painted the boat and re-sealed the trim tabs, eliminated the lifting rings in the back and the ladder mount. I'll grind the crack and will glass over it.
