The kill switch has nothing to do with the grounding of the ignition coils. It grounds out the prime side of the coils when you push it to stop the engine. As racerone says in previous post you have to check if it can jump spark at least 1/4 in in atmosphere. Those inline spark tester are no...

The phase maker system can be really tricky. The bad thing is if the CDI is bad there are no aftermarket replacement. Then you have to look for used parts at Ebay, Craigslist etc.

Topflie8979 one side of the coil should be connected to ground. If the coil has one thin wire (prime side) and one thick wire (HT wire to the spark plug, secondary side) you measure the prime side at the thin wire to the iron core and secondary side from HT wire and the iron core. Remember that...

OutboardBuddy this one has old school magneto ignition, no crank position sensor. The system contains of two ignition coils , two points and two condensers. Topflie8979 ignition coils should read 5-8KOhm at secondary side, prime side 0,5-1,5 Ohm. Clean the points and gap them to 020 in and check...

Check out the 3-cylinder 50 and 60Hp from mid 80.es. I think from 1985 (red-black-brown decals on the hood) and up, PTT from those might fit.

hl your are in the wrong forum. Go to Mercury/Mariner forum, the 150Hp Mercury 6 inline is a different animal than Force/Chrysler engines. BTW you have to pull the power head to change the water tube seal.

jbabka2000 you can narrow it down to 1962 or 63 year model. I think Merc 110 was from 1962, before there where Merc 100, 150, 200. They had the gear shift built in in the steering handle. Shifting and throttle was all in the handle, no shift lever at the side. They also had an other top cowl...

Most of those Mercury and Mariner the switchbox fails. From my experience the switchbox and stator fails, not so common with the trigger.

You have to pull the power head off to access the water tube seal.

You need to have the engine deeper in the bucket. The water pump impeller is not self priming, the impeller housing have to be under the water line.

That is a 1985-86 year model and as racerone marketed as Mercury and also marketed as Tohatsu. Here in Europe it also was rated as 4Hp, I have maintain a couple of these and it is a good motor but with a noisy crank it will be expensive to fix.

Chris1956, unfortunately maxrules only have diagrams for the lager 4 cylinder Force engine.

The killswitch grounds out the CDI box. Disconnect the wire from the CDI and should have spark if there is no another issue.

Look at my answer in you other post.

There should be two marks at the flywheel. One is 36 dgr BTDC and the other is 0 drg (TDC) for top cylinder. Are there only two marks at the ignition plat/flag? There should be three, one longer and two short at the right and left of the long one. The long is zero and the left one is +2 dgr and...

Yes, that is what we mean by stickers at this forum.

Pull the top carb and check it again. Check needle inlet tip and seat, check and adjust the float level. Turn the carb upside down when reassembled and blow in the fuel inlet. You should not be able to blow through. If still problem check for repair kit. Try Franz Marine Service if you need new...

Dmknox98, pull the LU off then you can determine if the power head or the LU or both are locked up. The drive shaft is always engaged with the forward and reverse gear through the pinion gear. The clutch dog engage the forward and reverse gear when shifting. Most parts are the same as for...

You pull the handle out to disengage the gear, not up and then push the handle forward to advance the throttle a bit.

My experience of these Mercury is that the ignition coils goes bad. They spark in atmosphere at plugs and with a spark tester. But if you put them in a spark tester Mercotronic or similar (coil tester out of the power head) the insulation between the prime winding and the secondary winding in...
