I just bought a boat with a BF225. I want to change the water pump, I have all the bolts out but can't figure out how to loosen the shift shaft. Any suggestions?
 
What do you mean you can't figure out how to loosen? Do you mean you can't find the joint? Do you have a manual? Is it frozen?
 
No, I don't have a manual, but I've had yamaha's all my life and you take the 7 screws off and they fall right out. I just want to know if there's some procedure to loosen the shift shaft.
 
There is a hidden screw under the trim tab adjust and there is a door on the side of the extension tube at the top to access the shift disconnect. Probably need a manual if you are going to do work.
 
I have dropped my Lower unit many times my shift tube is on a splin and once I get all bolts out, I take a pair off locking needle nose pliers and clamp tube where you see tube right below cowling above exhaust area, then when if lower unit doesn't drop I use a rubber mallet to softly hit bottem foot to help it drop .. Once unit drop's shift tube stays then when I come back to reinstall I just have to mess with bottom spline... reminder to grease bearing looking up where shaft goes in, also I lube up shaft it self seems to help it slide back up in case.. I really agree with getting manual for your motor, its well worth it I have always bought service manual for any motor I get.
