I have shopped Crowley Marine for several years and have always had nothing but excellent service. Very happy customer. Your parts reference diagrams are extremely helpful. Thank you.

Problem fixed: engine & sterndrive installation

I removed a 200 HP Yamaha V6 outboard motor and I rebuilt and installed a 1977 Mercruiser MC1 I/O into my 22' Wellcraft work boat. I bought several parts for the outdrive and engine during this process. The Yamaha used about 18 - 19 GPH plus oil. The Mercruiser is about 6 GPH +/- not quite as fast but a huge savings.

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: 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
