i think i have lower unit issues, but what exactly i don't know. i was cruisin' along at full throttle (didn't hit anything) and suddenly the motor is racing and the prop isn't spinning. there is no "click" when i put it in forward or reverse. any ideas?<br /><br />also, i've loosened everything that appears necessary to remove the lower unit, but it still won't come off...PLEASE HELP!!!<br /><br />
