Mercury 650 65hp

Replacing water pump in 1968 Mercury 650 65hp outboard. I used the prints y’all have to identify the parts, part numbers I needed. Made it easy for me. I appreciate Crowley Marine and will buy from you again. I’ve recommended you to family and friends.

Problem fixed: needed water pump changed

When I ordered the parts the discription wasn;t detailed enough on the web site and I ended up ordering extra parts that were not listed in the kit. If you need a pump kit for a 470 don't order anything else it is all there in the kit.

Shipping just a little slow. I think processing slow.

Problem fixed: lower end, water in. No water out of witness hole

Replaced seals and water pump . Made my own pressure gage to check for leaks. For fitting I used 1/4 in galvanized pipe and re threaded to 3/8-14 , fit oil vent screw hole fine. used a rubber hose and small ball pump to pressurize. put air gage in line with a tee fitting . that way you wont over pressurize and watch for leak down
