I gave four stars because they waited on shipping my stuff I ordered and I had to call and ask what was taking so long. They said they was waiting on two little washers to come in so they could ship it all together and I asked how long that would take they said end of June so I canceled those washers just so I could get the other items shipped. They didn’t even offer to send the items that they had in stock after I was told that was what was going to be done.

Problem fixed: Fuel related miss

A relative borrowed the motor, not sure what he used to put fuel in the tank but when it came back the motor had a noticeable miss. There was silt in the fuel tank, it had choked up the fuel cock and was throughout the fuel system. Replaced the fuel cock and filter, cleaned out the tank and fuel lines, removed and cleaned out the carburetor and it's back to how it should be.

Good to excellent. I have placed 2 orders over the last month. 1 st order was a little rocky likely due to age of kicker motor and needing to source parts as well as parts for a newer main OB. With order for parts under one order all parts were shipped together. One part was missed but support took care of in a matter of days. 2nd order placed as some additional parts were needed and received w/in 3-5 business day period

I ordered parts for a 1996 Jhonson 4HP from N Ireland for delivery to my father-in-law in the Adirondaks. My wife would then collect on a visit. The process was seemless and I was particularly impressed with the communication aspects. An excellent service. Many thanks

Problem fixed: Motor would stall and flood, water in lower unit with bad seal

The cap on my oil injection tank was plugged, The motor would flood with oil when it got hot from pressure build up in the tank during the week when stored. The Motor would starve when running the motor because it couldn't breath. I changed the lower unit oil on the motors put new seals on the screws and replaced one screw. All these repairs saved me close to 400$ this year, but I bought 2 new gas caps for my old tanks and the rubber seals on the caps were made with a pour grade of rubber they warped so I put the old ones back on the tanks. All in all I was happy
