Re: how the heck do you add an attachment

[David Stanton]

Best to pull the whole lower unit and the driveshaft and water pump come with it as one assembly – this all comes off easy – then you can turn the whole thing upside down to work on it. I put a thick rag around the housing and clamp it somewhat gently in a vice – upside down, of course. There is a small access cover with two screws part way up the exhaust housing that gives access to a disconnect for the shift rod. It’s also a good time to replace the water pump impeller if it’s old. If you haven’t found instructions for this job online, I strongly recommend you buy an aftermarket repair manual. Seloc and Clymer print them. Se links below, and if you surf the web you may find them cheaper:
The manual will likely help you with future repairs also.
