How to take apart lower unit off of upper unit

[Fcracer40]

Hello, I have a Yamaha CV85ELD engine and I'm trying to get to the water pump. But I took all the bolts out of the lower unit I think and it still won't drop down. Please help!! Thanks again Jeremy

Did you remove the anode and remove the bolt that us underneath the plate?

lwr unit

you should NOT be touching anything from the sounds of it !! I see SOOO many pwr heads brunt,, because blow joe mechanic thought he could do the impeller......in the last week I have had to redo 2 w/p impeller on two yamaha's that were serviced at two local shops and both had the wear plate to cup "O" ring damaged and on one,, half the o/ring was missing...its easy to make a mistake...so..do try and save yourself a few bucks and mess it up ???

There is a lot to respect about what Keith said about damage and additional expense when do it yourselfer numpty's get it wrong.

That being said, this also isn't rocket science. A good mechanically minded soul, who knows how to use tools, has a descent set of tools, can read and understand instructions, and is aware of how things were taken apart and can put the back the same way. Someone who has the appropriate manual, instructions, and IPC (illustrated parts catalog) these are invaluable when reassembling to see a hardware stack or part orientation in an exploded view.

And then, having a resource such as a mechanic friend or a web forum, where if you are unsure, you can ask a question and get a straight honest answer.... invaluable.

That being said, you are responsible for the outcome. Use a torque wrench. Use a torque wrench correctly.

Thanks for the replys the water pump works fine but its been setting for six years and just want to replace it. I've done a mercusier before but this one seems stuck like its corroded together.? I dont want to brake anything.

If all bolts are out and shift shaft is not holding it the problem is corrosion on shaft in power head or the housing at bolts. either one could be a major problem
