Its a 1648 lowe semi v riveted w a 27hp MBLT w 24hrs on the motor has driving and nav lights with nice galvanized trailer, all bearings are in good shape. Fella is askin 4500. What yall think?

What year is the boat and motor? What does the bottom of the boat look like? That hull is not a good match for a mud motor. I would not consider paying anywhere near that much for that combo. If the boat is in good shape, it's probably worth that much, it's just not a good combo.

not sure of the year but the boat is in good shape, I have a good buddy that does aluminum welding and owes me a favor. what good would it do me (if any) to have the rivets welded?

a riveted boat is stronger riveted than to have the rivets taken out and welded. the lateral bracing is also gonna cause waves in the bottom after a while. boat would still be good for an outboard. buy it all, sell the hull and get ya a new hull better suited for it.
