we have done all that, does it matter if we put it forward befrore or after taking apart?


Expert:  Tan replied 7 years ago.
If your not taking the upper off it does not matter only for reassembly. If your pulling the entire drive you have to put in forward. Your water tube should have a plastic guide tube in the water pump the old one is slid up the tube on the upper tube. If you don't get the tube right this will prevent the lower from going up all the way. Thanks post back if still having a problem..Tan

we got one side, now we cannot get the other one off to grease the u joints & re-assemble? CAN YOU THINK OF ANY THING THAT WOULD PREVENT US FROM REMOVING IT.

Make sure the drive is in forward gear. If it still won't come off put a piece of wood between the top of drive and the transom shield to get leverage to pry the drive off.Tan
