I use http://www.boats.net for a lot of parts. They have great parts diagrams and listings.

The company I would recommend w/o hesitation for Mercruiser parts is http://www.bammarine.com/

This is a great company w/ terrific people.

Their web site make it easy to locate and select the required parts.

On my boat, I redesigned my exhaust system from having salt water in that expensive cast iron 24/7/365, to now flushing w/ fresh water, then salt away, then draining bone dry until the next usage. Those obscenely expensive cast iron parts will now last much longer.

I did my 2004 340 Sundancer 8.1's myself. I bought parts at ebay. I mis-read the information on the part numbers and bought the standard elbows. My 340 needs the tall elbows(no risers), so I had to buy those. Now I have standard rise elbows that I can't return.
So....If you know anybody that can use them, they are brand new! Don't make my mistake when buying your parts.
I replaced everything with new, including the temp sensors. If you've not done the job before, there will be some instructions and references that do not match the Maintenance Manual. New style installation uses head bolts, not studs with nuts, same with the elbows. The torque may not be listed in the manual.
I also installed a freshwater flush system that includes a connection to the Gen & A/C pump. I can flush my engines, Gen, & A/C cooling water circuit without opening the hatch. I do as Wingless after each running: fresh water, then SaltAway.

Wingless, how did you do the freshwater flush?

After market brands are a lot cheaper but I know no one that gets the longevity out of them. Stay with Mercruiser parts and bite the bullet
