Re: 89 evinrude v6 xp 150hp ran hot will not start
If you have spark, the only other issue would be fuel. Some things to check: 1. are the plugs wet or dry after you crank it? If the plugs are dry, you are not getting fuel. If they are wet, you are getting fuel, but you may not have spark. 2. That engine is very, very hard to start when cold if the choke does not work. You can test that system, by pulling the tiny hose off the top of the top carb. Turn the ignition key to on, and push in on it. You should see fuel coming out of that small hose. If not, check the choke solenoid-it may not be funtioning. 3. Prime the fuel hose bulb. That forces fuel into the carbs for cold start up. To check for fuel at the carbs, pull one of the two bowl drain screws off. You should see fuel coming out of the carb. 4. Check for any iognition wires that may have gotten overheated and may be grounding out to the side of the block. 5. Fill a typical household spray bottle with fuel that is properly mixed with 50-1 outboard oil. Remove the airbox cover. When cranking the engine, spray some fuel/oil mist into the throats of the carbs-it should start. 6. Back to the spark issue. It's easy to check for spark when cranking by using an inductive timing light. Leave the plugs in when cranking. The gun will show the spark quality in the flashes of the gun. It will show misfires, nofires and weak spark. 7. That engine must turn over around 250 rpm when cranking in order for the ignition system to fire. If your battery or starter is weak and you are only cranking at 200 it won't fire the ignition system.
