Engine: Yamaha F40 Shopping experience: Excellent. Parts as described and delivered within two days from USA to Australia Repair difficulty: Medium Repair time: 2 to 4 hours Repair symptoms: Engine spluttering when accelerating Removed main jets and pilot jets and replaced with larger jets. Engine runs like new. Followed a you tube video I found on line

Engine: Yamaha Shopping experience: Everything came as ordered .. tracker was spot on .. would order from them again Repair difficulty: Medium Repair time: Less than 30 mins Repair symptoms: Carb jet replacement

Engine: Yamaha 4 stroke 40 hp Shopping experience: This is my second purchase with Crowley marine. Prices are good and shipping is always fast. Will definitely be ordering again. Crowley marine is definitely A+ Repair difficulty: Hard Repair time: More than 4 hours Repair symptoms: Engine bogs down and stalls when accelerating. Removed carb assemblies. Rebuilt and replaced jets with larger ones. Engine is prone to this issue since the factory jets are to small and plug up easily. This fix works well and engine runs better than it did from the factory.
