Same as every time. Placed order using in stock information.Weeks later, still waiting while "in stock" parts are being ordered. I get very annoyed, call office. THEN service gets good with the follow up. I worked for 50 years in customer service, and in my mind you have problems that need a lot of attention.BE TRUTHFUL UP FRONT! People understand. Lie up front and you have a mess!

Problem fixed: Needed rings due to low compression

Job is taking forever because of the weeks and weeks to get parts. You try to buy everything up front, but there are always more small things that you find that you did not anticipate and the weeks and weeks start over again. Mechanic doing the work is a Master ASE certified Mechanic.

Problem fixed: Low compression

Had to replace the piston rings on my 1980 Evinrude 15 hp. Bought it thinking it wouldn’t be that long of a project... little did I know you have to completely take down the entire outboard to get the engine out and then completely take down the engine to get to the pistons... good thing Crowley had almost every part I would ever need to get the job done!

Overall, the experience is good, I get the right OEM parts delivered to my door in a timely fashion. All the parts were in stock. However, the cost of shipping to Canada with taxes and other fees seems to almost double the expense of the parts making it less feasible to resurrect these old motors.

Problem fixed: Low compression, 30-60 psi

I received this motor as part of a package deal; it had very little compression in each cylinder. I disassembled it and found the lower rings on each piston to be stuck and one reed valve stuck in surface rust. I completely cleaned all the parts, honed the cylinders and replaced the rings, seals and gaskets. I also had to replace the recoil starter spring. The compression is now about 110 in each cylinder(before break in). Too cold here right now to do a test run..
