Re: 140 i/o merc wont start. need to wintrerrize.. help!!!!!
Port Jeff.. <br /><br />If you are selecting to start the engine prior to putting the boat away for the winter, ya gotta start with what you've learned thus far..<br /><br />You know you aren't getting spark to the plugs so..forget the fuel issues till you get good spark.<br /><br />Read and follow Ratanna's post .<br />If you do everything he said to do you may find the cause for no spark, and be done right there.<br /><br />If not,<br />and assuming you have juice at the coil positive terminal, with key on....<br /><br />- Remove the distributer cap.<br />- Ground your test light then stab (and hold pressure) on to the metal plate that your points are screwed down to.<br />- Have someone turn the engine over.<br /><br />If the test light lights even a very DIM light, while turning the engine over, your points are grounding out inside the dist, meaning the juice that is supposed to go to the plugs is grounding out.<br /><br />- Replace the points and condensor.<br />- Use a match book cover to set the points while the point lever is sitting on the HIGH lobe of the distributer shaft.<br />- Put the earmuffs on the outdrive / turn on the water...<br />- Try starting the engine with the new parts.<br />- If it starts right up, shut it down and set the points the right way with a guage.<br /><br />If it still doesn't start / come back here and tell everyone what you learned.<br /><br />PS: If you do not have juice at the coil positive terminal with key in the on position, run a jumper wire from your battery positive terminal direct to the coil positive and attempt to start the engine.<br /><br />If it starts, disconnect the positive wire and start chasing for a bad connection from the coil positive on back..<br /><br />Don't forget to check the LARGE ROUND ELECTRICAL PLUG right on top of your engine. <br /><br />Unplug it - spray the death out of it with PB Blaster, then plug it back in again.<br /><br />Moisture gets inside them and causes all kinds of crap to start happening.<br /><br />Hope this helps you out some..
