Good place to shop. Parts diagrams great help in finding correct parts to order.

Problem fixed: Engine rebuild

Bought a 2003 Johnson 9.9 for 150.00. Was reported to be burnt up from running on straight gasoline without oil mixed in. Rebuilt the power head and have been running the motor. Crowley Marine made the parts acquisition easy!

Problem fixed: Thermostat replacement

Just unscrew it don't crack the cap while taking off you can't get a new one. Then just take it apart and replace the internal parts . Remember to use a lot of grease on the threads to get it apart again.
