1992 70 hp Evinrude E70TLEND- STARTING PROB

[903ASP]

Hi guys. Doing this for friend/neighbor. He was on fishing trip, and returned early, because 1 out of 10 times, motor wouldn't start. He has no manual, so i found this site on line, and also ordered him a service manual. He believes it's the power pack, but at $100 plus, i suggested he wait until we receive manual, in hopes that it gives volt/ohm meter testing process for power pack, coils, etc., then make informed decision. Do you agree, or do you believe it is beyond a doubt, the power pack?

Often the powerpack is blamed for some reason ?--------Is the man raising the fast idle lever ? Is the man pushing in the key ( while cranking ) to activate the primer / start injector ?

Remove the spark plugs... borrow or buy a spark tester from a automotive parts store, set the gap in the tester at 7/16". Check each plug wire for spark which should be a strong blue lightning like flame... a real SNAP!

If there is spark as above, then obviously the ignition system is not at fault.

If there is no spark, disconnect the Black/Yellow wire that leads from the engine's wiring harness to the powerpack (kill circuit) and check for spark again. If you now have spark, replace the ignition switch.

A side note... I assume the boat has a tachometer, and if so, does it function properly?

Let us know what you find.

Don't know the answers to those questions Racer, but he's had the boat since '97, so i assume he's got starting procedure down pat

Will do those things Joe, as i myself am fairly familiar with standard engines. Have never worked on boat motors before though. Will wait for service manual, before i delve too deep. The motor is in a Starcraft, a Superfisherman i think? I can only assume it has a working tach?
