    1989 Force 150 ignition

    Re: 1989 Force 150 ignition I have a 1988 125HP motor. I looked into the MSD systems. The MSD units for the distributorless ignition systems were more than what I was willing to spend. The lower cost units either required a distributor, or you would have to have a separate box for each...

    Took the head off my motor, heres a video explaining everything.

    Re: Took the head off my motor, heres a video explaining everything. No I'm not 100% sure about the size of the nut. You'll also need a flywheel puller like this one. You'll also need a torque wrench to tighten the flywheel nut and other bolts. Actually it's best if you have two torque...

    1989 force 125 wrist pin help

    Re: 1989 force 125 wrist pin help I've used a 2 ton press like this. Took everything I had to get it done though. I used the Wiesco forged pistons as a replacement which use "floating" wrist pins and keepers. Pins go in with just finger pressure with circlips to keep the pins in place. If...

    impeller shopping

    Re: impeller shopping L-Drive motor is mounted inside the boat and is connected to the lower unit with a shaft and u-joints. This is what it looks like. The lower unit sticks out the bottom of the boat. Regular 120HP outboard is mounted on the back of the boat like this.

    90 HP force ignition help

    Re: 90 HP force ignition help 200 ohms would indicate that the some of the windings in the stator have shorted together decreasing the over all resistance and probably lowering the stator output voltage to the CDM's. Your stator is bad. Those burnt yellow wires are the stator output to the...

    Automotive or custom pistons?

    Re: Automotive or custom pistons? The Wiseco forged aluminum 2-stroke pistons for the Force motors are pretty stout. They even come with floating wrist pins just like the forged 4-stoke high performance automotive pistons that they make. No need to modify automotive pistons. The dome of the...

    Pulling the flywheel

    Re: Pulling the flywheel Make sure you have good quality bolts that are long enough to thread all the way down into the three holes in the flywheel. Preferably grade 8 bolts. I'm assuming that you are using a puller like the one pictured below. Once you get the large center bolt as tight...

    Chrysler 105hp water flow help! PLEASE!

    Re: Chrysler 105hp water flow help! PLEASE! Quite a bit of corrosion you have there. I suspect that you may have a problem with the adapter plate that is sandwiched between the block and lower leg. Looks like the holes you are referring to where water is coming out of are actually part of the...

    1994 120 force o/b won't start

    Re: 1994 120 force o/b won't start Those stator resistance readings are definitely not within specs. Green - Green/White (I think the color is actually Blue to Blue/White, probably faded a bit) should be between 3250 - 3650 ohms. Red to Red/White should be between 75 - 90 ohms. I agree with...

    1994 120 force o/b won't start

    Re: 1994 120 force o/b won't start Maybe check the ignition system??? I've been fooled a time or two by visually checking the spark at the plugs. I've learned that just because you have spark, doesn't mean that the ignition system is working 100%. I made a similar rig as you have several...

    70 CHRYSLER setting up since 1987

    Re: 70 CHRYSLER setting up since 1987 Make sure you can turn the motor over. Put on some gloves and grab the flywheel. Try turning the flywheel clockwise (looking down at the flywheel). Might have to use a big wrench. Is that a crack on the lower unit? See arrow in attachment.

    Thermostat

    Re: Thermostat The thermostat housing is mounted at the top of the head (red arrow). Has 4 large screws holding it on. Sometimes the screws are corroded so they can be hard to get out.

    force 150 wont go above 3000 rpm feels like a 50 horse

    Re: force 150 wont go above 3000 rpm feels like a 50 horse Typically the idle "air/fuel mixture" screws on the carbs themselves should be 1 to 1 1/2 turns out from lightly seated. Idle "speed" is set by adjusting the screw on the towershaft (see red arrow). It has a lock nut to prevent it...

    Re: 1992 Force 120 - where is idle adjustment screw??? It's located on the tower shaft. It's the screw at the left end of the yellow line at the bottom of the picture and has a nut to lock it into place.

    Cant get fly wheel on L-Drive

    Re: Cant get fly wheel on L-Drive You have the wrong flywheel. Here is a picture of the flywheel that you need. Note that the top of the flywheel is flush. Later model flywheels have about a 1/2" lip around the center hole and is internally threaded. This will not work. You need one that...

    1998 75 HP Force. Misses, stalls hard to start. UPDATE!!

    Re: 1998 75 HP Force. Misses, stalls hard to start. Re: 1998 75 HP Force. Misses, stalls hard to start. Look up under the flywheel for a missing stator magnet. Missing magnet will not allow the stator to generate the proper ignition/charging voltage. This is what the flywheel looks like from...

    10 min Spark tester...with photos

    Re: 10 min Spark tester...with photos Yes I've seen several of the ignition checkers out there. I wanted something that I could use to check the ignition with all of the actual plugs that I was using in the motor at the same time. I use a remote starter switch which is basically a hand held...

    120 Force Cooling

    Re: HELP!!!!!!!! 120 Force Cooling Re: HELP!!!!!!!! 120 Force Cooling Nothing that I can think of. The water flow from the pump goes up the tube to the bottom of the block and into the exhaust cover. From there it goes to the water jacket down the left side of the cylinders then up the water...
