Serious you had oil injection failure? What oil was being used at time. Yamaha is considered bullet proof and never fails

All motors need preventative maintenance like draining/cleaning water/sludge from tanks and lines changing filters if there are any and checking check valves and lines

If it is a YAMAHA and you have a bad rod, the motor is scrap. Once you open it up you will see what I mean. One piece connecting rod.
Hope that was a joke about about them being bullet proof. I have 2 and have become very disillusioned with them. Occasionally turn a wrench on OMC, MERC and VOLVO out drives. Not much of a problem. For some reason ( alloy perhaps ) YAMAHA bolts are prone to break off. regards FRED
