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

    When I tested every second wire from #4 down showed continuity to the mounting bolt at the end. And that was on both motors. The only one that didn't was for #1 wires which showed OL for both wires to the bolt and 55 ohms to each other.. So I think that there is something going on. Have no clue...

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

    OkForce Power, so I don't know if I am doing it right but I measured resistance between all the 4s, 3s,2s and 1s. I fillmed it all. Between the 1s I get 55ohms and between the last 2 and first 1 I get OL. The rest are 51 or 52. The other motor shows 51 or 52 also. Mostly 51 ohms. So between tye...

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

    https://www.dropbox.com/scl/fo/mypyevg9vnus8e1hkkfvt/h?rlkey=bgyg6s411ipnzyya8pru95jyi&dl=0 In the link there are 3 videos on at idle second in gear at higher rpm, third pretty much same. In the first one you can clearly hear and see the issue. Sometimes I heard a little choking. I am trying to...

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

    The rectifiers are the enclosed square ones with wires not the older rectangular ones with poles. I have no clue if they have a regulator built in.

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

    Ok so I bought the 800 cca starting battery and installed it next to the deep cycle one. I plan to install a switch: Off, 1, 2 and All. So my question is can the stator for the 120 charge 2 batteries, is it strong enough? I am gonna do the same on the other side for the other engine. I mean I...

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

    I was wondering I can fit 2 batteries on one side and only one on the other. I have 2 Lowrances lives 9 inch, 3 night lights, 3 transducers, at least 3 pumps for bait and bilge and stuff. Can I just buy a 1k cca starting for both engines? Found one 27M at Pep Boys for 140. I think I saw the 24M...

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

    Actually, I am at the end of the issues, one motor is completely rebuilt top to bottom. I am ironing out the kinks now. if I were to change the motors I would probably do one 200HP motor not 2. But after all this work I don't want to take that route yet. I understand these motors inside out...

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

    Ok but my question stands should the reading with a voltmeter read say from a standing 12.5 battery go up right away or really slowly. When I read it with a voltmeter it went up slowly, I mean really slowly like 1 volt at a time it didn't jump up to 13 or so.

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

    Batteries are SuperStart Marine Deep Cycle. I almost always charge them before going out. I don't know if I did that when I took the picture. The motor was acting up so maybe I turned it a few 20 times and one went down a bit. When I did test it at idle it was really slow to gain voltage but...

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

    Have a question on the stator, when I used the multimeter I noticed that the stator is charging differently that an alternator it is slow on building up the charge, at least on one engine it doesn't just jump up from 12.5 to 13.5 or so.The other one also is going upslowly but a bit faster than...

    Need to adjust the dial 1990 Force carbs mixture

    Not since I got the idle to work. I did take it before twice. But the wires were bad. Now the wires on the intake side are all good. Also the ignition is new as far as switch and kill switches and works properly. Waiting to take it out this weekend for carb mix setting as per Jerry 1 1/2 out in...

    Need to adjust the dial 1990 Force carbs mixture

    Ok I got news so fixing the wiring yesterday, plus new ignition switches and kill switches managed to get the system to work properly and the kill switches also function now. The engine that wasn't idling now has idle and runs ok but it has some hiccups or studdering while running. I made a...

    Need to adjust the dial 1990 Force carbs mixture

    Ok so one engine still starts regardless of kill switch plug in or not. That ignition shows ground on the yellow wire the other doesn't have it. I have to see if I unplugged anything at the motor in the morning. But the kill switches are new and opened when the lanyard is plugged in. I don't...

    Need to adjust the dial 1990 Force carbs mixture

    Ok got the new ignition switches and I tested them with a meter. So when the key is off there is continuity between the two M connectors on the switch. As soon as you turn the key the circuit opens and the kill switch becomes the one that controls the continuity. So I have to check if the switch...

    Need to adjust the dial 1990 Force carbs mixture

    I just found out thatvone 9f tye engines thatbI thought was adjusted and was ready to go had the idle adjustment bolt come loose and that's why it wasn't holding idle. I forgot to lock it up with the nut. Oh well at least thatbone is good. Working on the trigger wiring repairs on the other...

    Need to adjust the dial 1990 Force carbs mixture

    This is a diagram that I found it looks pretty close to my ignition except the blue wire that goes to M is black on mine.

    Need to adjust the dial 1990 Force carbs mixture

    Ok so the white wire that has the ground which goes to the junction box and connects to 2 black/yellows was connected to the ignition switch M see 1st picture. I am including the ignition switch diagram I wrote picture 2. The other ignition switch fell apart when I touched it so I have to...
