Repair Time
2 to 4 hours
I will buy from Crowley again, but only when it is specific engine parts. It was impossible to find information about rigging for the Mercury engines on the Crowley website. There is a rigging section, but it only applies to Yamaha and Johnson.

Problem fixed: Poor acceleration, cavitation

Rebuilt the OEM stator by welding vanes and polishing. Replaced standard impeller with high skew impeller, replaced control cable boots, and replaced wear ring.


Great products and huge help to have all the diagrams for all models. Recommend to all and wont go anywhere else!
