2001 80hp four stroke Yamaha/ lower unit issues
Was driving my boat at 75 % power and a loud thud and the motor was still running but the prop would not spin. Tried reverse and forward but nothing!!! I guess one of following.
1. Lower unit seized up ( seems odd as motor supposedly has 350hours)
2. Shift cable broke/ tried shifting and it felt same as always in terms of resistance
3. Shear pin broke( assuming that this motor has one) I did not hit anything that would cause it to break ie no logs etc.
After hauling boat out I tried to spin prop by NAND and it was very stiff / not sure if this means anything...
Any hints or suggestions greatly appreciated.
