As long as the blades do not need alot of welding it would be 85 plus tax. We balance all the blades and can add extra cup to complement the tunnel hull. Another 12 bucks or so for shipping if you do not want to drive to lafayette. One thing to remember with that 125 is the holeshot will not be as good as some engines. It only runs on 2 clys untill you get over 2500rpm's.
