After the coupler of my boat was wiped off, also I found the my lower unit was stuck there too. I was very confused and sad that how the coupler and lower unit were damaged at the same time. So I bought another outdrive which is old style and really I do not want to.
During buying the old style outdrive, I did a testing, changing the shift switch and turn shaft manually, the propeller also turn in correct direction. So I checked the water impeller and it was broken. So I took the impeller from my broken one and put into old style. To my surprise, it is stuck too after I mount the lower unit into upper. I also did the testing again without impeller, it works even my old outdrive.
I think my old outdrive works, I can do the testing without impeller, But it cannot turn while I mount the water impeller.
in the attached pic is old style outdrive, the water impeller was broken, But after I mount a working impeller, the whole outdrive is stuck. Will it be damaged after I mount into my engine?
I am sure , the lower unit gear works. That is good news. I have to spend 1000 or 200 to buy a working serviced one.
