Tyler0420 Posted April 1, 2016 Author Report Share Posted April 1, 2016 Ill try that. But pretty sure as soon as I lift throttle it cuts out. Wish it had a idle lever Link to comment Share on other sites More sharing options...
Chrisb Posted April 1, 2016 Report Share Posted April 1, 2016 Cutting out when lifting the throttle would indicate a lack of fuel. Fuel could be draining back as it sits. Inspect all fuel lines closely for cracks. Link to comment Share on other sites More sharing options...
Tyler0420 Posted April 2, 2016 Author Report Share Posted April 2, 2016 Wow thanks for all the replys guys. I'll be taking a look it this weekend. Maybe even take it for a troll Sunday (only need to start it once lol) Cutting out when lifting the throttle would indicate a lack of fuel. Fuel could be draining back as it sits. Inspect all fuel lines closely for cracks. lines were replaced last fall. Link to comment Share on other sites More sharing options...

gunner-2 Posted April 2, 2016 Report Share Posted April 2, 2016 Good to hear Tyler0420 just don't go to far the first time till you know it's running good for is that the only thing you had to do so far? Link to comment Share on other sites More sharing options...
Botchegalupe Posted April 2, 2016 Report Share Posted April 2, 2016 Found the following on a tech site: Whenever an engine is stopped the temperature goes UP and then slowly down again. This temp increase in coils etc might be enough to reduce the coil-output or in cases shorten coils/powerpacks/capacitors/points due to thermal expansion. Purchase a can of freeze spray and use it to cool down the coils after the engine has been running for about fifteen minutes, I used to use this technique frequently to find intermittent faults when I was an electronic technician in the navy. If the motor starts after the coil is cooled down, you've saved yourself a couple of hundred bucks in labour costs. You should be able to purchase a can of freeze spray at The Source.

bassmaster24 Posted April 5, 2016 Report Share Posted April 5, 2016 First of all, get rid of the old gas. Run new with seafoam, check your vent. I bet you have air lock. If not try starting without choke after you wait the 15mins, if it starts then you were probly flooding it. Link to comment Share on other sites More sharing options...
jesse Posted April 5, 2016 Report Share Posted April 5, 2016 Yes my friend was trying to use 1 year old gas is his mower & it wouldn't run.I told him to dump the half full can on the fire pit & put new gas(not gales) in it.Did that & it ran perfect,the gas would not even light in the pit.It was like starting diesel fuel.Old gas is bad news Link to comment Share on other sites More sharing options...
ron4blues Posted April 6, 2016 Report Share Posted April 6, 2016 Yes. Gasoline is hydroscopic. If it's been sitting a while, get rid of it. Link to comment Share on other sites More sharing options...
captnn Posted April 11, 2016 Report Share Posted April 11, 2016 If it starts the first time and not the second it is not gas. Check the gas for dirt or something electrical. Link to comment Share on other sites More sharing options...
Tyler0420 Posted April 11, 2016 Author Report Share Posted April 11, 2016 Jus went to crank it over today n no power when I turn the key. Only hear the choke open/close. Battery is fully charged. Link to comment Share on other sites More sharing options...

teedee Posted April 12, 2016 Report Share Posted April 12, 2016 if its not turning over when you turn the key look for loose or dirty connections at the starter . also have someone turn the key while you use your 12 volt probe to check for voltage ....td Link to comment Share on other sites More sharing options...

It's a good way to kill yourself. You got lucky this time. Link to comment Share on other sites More sharing options...
Tyler0420 Posted April 12, 2016 Author Report Share Posted April 12, 2016 Ok. So the last time it didn't start it was my fault. I only reached under the tarp n turned the key not realizing the boat was in gear n that's why it wouldn't start. But I was "not happy" n said screw it I'll check it another day. So same thing happened today. So I lift the tarp n it's in gear. Put it in neutral n it starts. So I lift the motor cover anyways n find some corrosion on the grounds for the coil packs (I believe). Should probably replace these wires Link to comment Share on other sites More sharing options...
teedee Posted April 13, 2016 Report Share Posted April 13, 2016 its a wonder it ever started with that much corrosion .yes replace wires and clean head and bolt connections . that should put a end to all your problems td Link to comment Share on other sites More sharing options...
Tyler0420 Posted April 13, 2016 Author Report Share Posted April 13, 2016 I didn't take any pics of the other wiring but it all looks good. Jus those 4 grounds were bad. I'll replace them n see how she goes. Link to comment Share on other sites More sharing options...
DaveC Posted April 14, 2016 Report Share Posted April 14, 2016 its a wonder it ever started with that much corrosion .yes replace wires and clean head and bolt connections . that should put a end to all your problems td I agree...thats some poor grounds.

Tyler0420 Posted July 29, 2016 Author Report Share Posted July 29, 2016 still boat problems, so today I take the motor cover off and start looking around. When I replaced the coil pack grounds I missed this one wire that was taped up. Looks to be the only shoty wire left in the motor. So I untape it n the wire falls apart. does this mean my motor is a 1987? Link to comment Share on other sites More sharing options...
Tyler0420 Posted July 29, 2016 Author Report Share Posted July 29, 2016 By some diagrams I looked at, could be cyl #4 trigger wire. Which would be my starting problem I hope. Now I need to look into replacing it. Link to comment Share on other sites More sharing options...

deetch Posted July 29, 2016 Report Share Posted July 29, 2016 Tyler, loosen the bolts holding the motor to the boat and go for a ride. That will solve all your issues! Link to comment Share on other sites More sharing options...
