    Merc 125HP on a 1996 Trophy, no spark and would not start before that

    Yeah it is not my boat, it is a 1996 model, with a Mercury 125hp outboard. For some reason I did not get notifications on the responses here. Sorry for the late post.

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    So I did the cranking timing at 28BTDC. Is this ok as I read some go to 30BTDC to get a better idle? I could be wrong on what I remember reading but it did say most ignore the specs on the timing.

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    Weird I could not get any spark on any of the spark testers, so after fixing the trigger wires for number one I put it all back and it started. I get spark on number one also. It doesn't look strong on the cheap tester, really faint red light. Maybe the daylight is causing the spark to not be...

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    So now I have no spark on any of the leads. I fixed 2 wires that came from the trigger. I tested by taking off the two yellows and no spark. Also the black and yellow at the rectifier. I am teying to find the tests for the stator and trigger with DVA adapter for 1990 model 120HP. Also I removed...

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    So unplug #1 and use the #3 lead wire in #1 for spark. I bought the DVA adapter and the spark gap tester. So as far as the trigger testing are there specific wires? Thanks.

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    Wanted to add that I just changed the rectifyer with the same kind that being the rectangular one with nuts for connections. The old one had a broken lead from ground screw to ground post. The other motor has the square one with black and 2 red wires plus yellow and gray. I do have 2 spare...

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    Ok changed the filters and one prime bulb. One engine is great. The other has idle issues. So maybe it is a new problem or it might have been there but just didn't notice. I was having issues with the motor at idle and decided to check spark. #1 has No spark, # 3 does. It is not the coil I...

    Merc 125HP on a 1996 Trophy, no spark and would not start before that

    So it was taken out last week and it died right at the LiveBait shop. Several attempts were made to start and it would start and then die. The owner did the compression test which showed 120s across but did not ground the cables so now it has 2 problems. There is a no spark condition on top of...

    1996 Force Mercury 120hp starts then dies HELP

    Ok so I don't know why I thought it was a Force but it is a Mercury 2 stroke 125hp with the white oil container on the starboard side. I am waiting for pictures from my friend on this. But it is a Mercury 125 for sure. I tgough I saw Force by Mercury for some reason. Looks like the picture

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    My inline filter on the starboard side had sand in it. I could not prime or pull any gas to it

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    I took the boat to a lake nearby today. The engine I rebuilt was the one with issues. There was hardlyany gas coming on the transparent filter when squeezing the prime bulb. I took off the filter and it broke on one side but it was also nasty inside it looked like there was sand in it. I...

    1996 Force Mercury 120hp starts then dies HELP

    Sorry for the typos I thought I fixed it. It's an 125HP model I don't have any books on the 125HP. I do have the 120s books 1992 and the Clymer manual that covers a bunch of models from 1984-1999. But the 125HP is not really explained. So I managed to fix 1990 dual 120s issueswith the help of...

    1996 Force Mercury 120hp starts then dies HELP

    Yeah, that boat has the switch bypassed. The spark disappeared after the compression test without grounding. I don't suppose there is a fuse is there?
