Question about Rock & Ice Climbing
Posted by Anonymous on
Hi, You did a good job of assessing the problem. It sounds like the float valve in the carb is the likely problem. This would overfill the carb when sitting, flooding the engine and the pressure in the bulb pump would go down as the fuel leaked out. Float valve should be investigated and that should Fixya!

has your boat been sitting more than 60 days. ethanol gas has been proven to only stay stable for 30 days in 90 degree + weather. Labor cost can be up to $100.00 per hour. CHEAP TEST- compression, spark, and fuel. TOOLS(1) A compression gauge (2) a spark gap tester.(3) A Clymer service manual for your engine. (you can purchase from your local dealer). I know all these are expensive but if your going to be a outboard owner you will always need them. TROUBLESHOOTING (1) check compression. without the year model I'm giving you a average numbers. Look at your Clymer manual for specific numbers. all cylinders need to be over 100 lbs and equal each other within 5 lbs.(2) check spark. use a spark gap tester all cylinders should jump a half inch gap. if you have good compression and good spark, fuel is the problem nine times out of ten. Drain gas tank,clean fuel lines replace primer bulb and replace all fuel filters. Finally replace spark plugs, I know spark plugs probably don't look bad but this is a outboard. Fresh spark plugs means less resistance for the ignition system. The ignition system is week compared to automotive. Test drive boat, if the problem is still there then there is further steps to take. Again I don't know the year model so I guessing its fuel injected. Pull out your clymer manual. what is great about the Clymer Manual for Novice techs is it gives detailed info on your outboard. Troubleshooting tips and teaches you how your outboard works.

My Mariner 8 has a thermostat fitted. It only pumps water when it heats to normal temp.
If your engine stops, it may be a fuel problem. Check the plug and go to Marine Doctor (a) fuel diagnostics, (b) spark plug diagnostics, sections. PK

It's a two stroke, it has a separate spot to put the two cycle oil under the seat. It injects the oil itself, so you just make sure its always has two cycle oil in there and fill the gas tank with straight gas.
