Quick response and good service.


Great ! Parts were here in no time!

Mariner 115 hp

The only problem I have with you guys you say you have something in stock and you don’t. So you hold up the whole order instead of shipping what you have.I know you do it for shipping cost. But you need to let customers know. They want to cancel what you have on back order. The part I needed was already supposed to be here. When checking I find it has never ship. The parts that was back order was not critical,but other part was.

It was good. However I provided the serial number of my outboard Motor three separate times.

Problem fixed: Replace Lower Unit

My LU finally threw in the towel, all the gear oil leaked out through the propeller shaft. A seal went or cracked housing? Big mess! Got a rebuilt from CM with no core charge. Ordered a H2O pump kit also. R&R of LU always a wrestling match. I use bungee cords to support the LU and power trim as needed to get OB vertical as possible. I also use a floor jack. Very helpful to remove clam shell and spark plugs. Last inch bind up issues due to crank shaft spline at the flywheel. I use a 15/16" socket and move slightly either way and LU pops into place. A must is to get the water tube sliding over the copper water pipe! Got er done!! Ready to hit the lake!

Shipping just a little slow. I think processing slow.

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
