Cracked crossmember on boat trailer

[senile1]

After removing the transom saver when trailering my boat today, I discovered that the crossmember is cracked where the transom saver attaches to it.  The crossmember is rectangular steel tubing.  This is a 1987 trailer for a 1987 15 1/2 foot Starcraft bassboat.  There are three crossmembers that support the boat and the other two are in good shape.  If I weld this crossmember properly will it hold or is there some other course of action I should be considering?  I'm trying to determine if I should weld this where the crack is, or just cut the crossmember off at the end where the original welds are, and replace the crossmember.

Usually the cross members are 14gauge box tubing, that is thin for the stress of the motor on it. Weld it up and either plate it with 3/8"flat bar on the leading edge or back the cross member up with another piece of box tubing.

Thanks for the response, Flatfish.  I've never had a crack in a trailer before and I wasn't sure what to do.  I'm waiting for a callback from my boat service department.
