Have only taken my new impulse out about 2 times ive never crashed it or hit anything and then the other day I noticed a small hairline crack above the transom looks like the crack did not even reach the fiberglass so it wasnt that deep so I lightly sanded and applied some epoxy I was just wondering if anyone else has experienced this and is it normal ? Are proboat hulls prone to stress cracks and is there any way to strengthen the hull before I take it back to the lake ?
