I have a 2003 50HP Tiller steer Yamaha, the main crankshaft bearing is getting noisey (I think it is the bottom one) I went to my Local dealer and asked for a price, he said if I dismantle the motor and bring in just the Crank, he will press off the old one and fit a new one for $2,000, now that seems like a lot of money for a bearing to me, I also priced a complete crank (with bearing) and it was almost the exact same price, is there a special tool/press to do this and is the bearing really expensive, or is it time for me to look for a new dealer???
