Hi folks, new here, just moved to Whangarei from ChCh. Bought my Dad's old Noelex 22 off my brother in Auck whose owned it the past six years. When he went to replace the Honda outboard 9hp the new model wouldn't fit, so he sent it back and went to Mercury who installed a 9.9. Trouble is it's very tight and the shaft touches the hull, makes it vibrate, and the locking mechanism gets stuck....to undo it puts fingers in danger when you have limited access in the motor well. Its so big ypu cant eve
