Outstanding as usual! Fortunately I do not need or Purchase many items for my Boat Motor, but when I do, it is from Crowley Marine.

Problem fixed: Hard starting, loss of Power and running out of Fuel.

Originally found Fuel lines deteriorating from within from the use of Regular Gasoline. Switched to Non Ethanol Fuel and replaced all Fuel Lines. Found Fuel Filter partially plugged and replaced. Found improvement in starting however still loosing power and running low rpm. Purchased all AVAILABLE parts to rebuild Fuel Pump and Carburetor from Crowley Marine. Parts arrived quickly and at reasonable cost! Repairs completed and now ready for a Great Bass Fishing season! Crowley Marine is the Best.

Great to get the parts I did for such an old outboard but disappointed that two of the items I needed that were listed as available were not available.

I will buy again from them. Was missing 2 pieces in my order and had absolutely no problem getting the problem fixed.

there was a glitch on the order. I didn't get a tracking number, so after 5 days, I emailed and they sent the order that day. Order was complete.

Problem fixed: overheating

Just a word of caution, change the thermostat when doing the impellor. My engine overheated and stopped. After a head gasket change and thermostat, it seems to be running fine (head and block were still dead flat), but I realize now that it never pumped this much water since I've owned it (5 years). So the thermostat was probably bad for a long time. I installed a tell-tail on the top of the block. Crowley always has the right parts for this engine, which is hard to do for the 1988 and '89 years.
