    Force 50HP Carb Notes: 1985, a 1987, and a 91-92

    I figured that ALL Force 50HP Carbs interchanged through the years. But these two are quite a bit different. The throat is a bigger diameter. The flange is much wider between bolt mounting centers. Even the bolt holes are bigger. My 1987 Force's carb part number is: WE17A - (Walbro I believe)...

    1985 Force Carb Flange. What is this barbed fitting on the intake under the carb?

    Thanks. Learn something new everyday. I always figured there was no unburned fuel besides the richening for lube and that everything that went into the crankcase got burned eventually. I guess it would eventually puddle at the bottom of the engine and create an issue. I suppose chainsaws...

    1985 Force Carb Flange. What is this barbed fitting on the intake under the carb?

    Naturally, and he put it back on the barb. My Force 50 doesn't have this, so the question was, what's the purpose of the hose.

    1985 Force Carb Flange. What is this barbed fitting on the intake under the carb?

    My dad sent me this picture. I'd guess maybe it's a pulse for the fuel pump but am not there to see it.

    What type of ignition does a 1985 Force 50HP use?

    In the video, the motor has points and condenser under the flywheel. I'm guessing my dad's 1985 50hp (in the picture) is also points. My 87 Force 50 has CDI ignition with triggers under the flywheel.

    What type of ignition does a 1985 Force 50HP use?

    My dad (who's working on his engine) says he thinks it has points and condenser like this 1980 Chrysler: Looking at his picture again, I think he's right.

    Here's a picture of the two coils.

    Force 50HP running with cheap Honda 5 Pin AC CDI.

    Update. Still works fine. I don't have a lot of hours on this, but no problem four years later.

    Which plug for a 1985 Force Chrysler 50 HP?

    I have an 87 with the surface gap plug (no L conductor). What does the 85 use?

    50HP Replaced impeller and thermostat. No water flowing. Where to look?

    Old thread but I think his problem was that we didn't have the lower unit aligned with the water pipe. He made sure all lined up and it works.

    50HP Replaced impeller and thermostat. No water flowing. Where to look?

    Not sure if maybe there's a clog somewhere.

    carb adj 1997 50 hp

    Heres the manual for a 125hp but it will likely be the same for a 50 but one carb instead of two. The manual says warm up engine and put it in neutral. Adjust the screw out (richer) until engine starts to 4 stroke (sputter). Dial it the opposite direction until it starts to run so lean it...

    Motor dies then won't start

    One other thing that I'd consider common with age when the primer never becomes firm with pumping is that the fuel pump diaphragm tears and no longer pumps. When this happens, fuel goes right through the diaphragm and into the crank case through the impulse hose (the small fuel line hose that...

    1988 85 hp Force outboard

    I have unscrewed that myself on my first Force almost a decade ago... I knew when the screw came out and I saw the rounded end, I had done something wrong. I put it back in before the works dropped down and all was ok. But... it taught me a lesson. At the end of the day it will just mean more...

    How to set the shift and throttle cables and mechanisms?

    I found a page in my manual about matching the shift rod to the shift mechanism in the motor caul that says find FWD mark the position, find REV mark the position, then set Neutral on the shift rod as right in the middle. I'm finding play in the mechanisms means I have to go from Forward to...

    How to set the shift and throttle cables and mechanisms?

    I noticed today that WOT on the tower linkage (50HP) is not fully opening the throttle butterfly. So I lengthened what I assume is the throttle rod here. That seems to fix it and now the butterfly is flat and parallel to the choke butterfly. But I'm also noticing that the shift linkage is a...

    Motor dies then won't start

    When in doubt, I replace the bulb and any fuel lines in question. Bulbs have check valves which can fail. The rubber becomes stiff with time (and gas drying out the rubber). I consider a primer bulb a 3-10 year item depending on if gas has ethanol in it or not. The other issue can be fuel pump...

    Force 50HP running with cheap Honda 5 Pin AC CDI.

    I was really watching it and checked both cylinders. I didn't want to have a case where the engine linkage was advancing timing AND the CDIs were also advancing and end up with say 50 deg BTDC. So I was glad to see 26. That's probably costing me a few MPH speed. I should check it at 30 deg BTDC...

    Force 50HP running with cheap Honda 5 Pin AC CDI.

    Update: I took the boat out on the lake today and ran a near full tank of gas through it. I checked dynamic timing on both cylinders. They're both running 26 degrees before TDC on top and bottom cylinder (I made a mark equidistant to the #1 cylinder's 0 and 30 degree tick for the #2 cylinder and...

    Warning on stator and key switch wires. Ouch!

    This was a dumb move on my part but I had the key switch out for replacement and had to hold it still with one hand in order to crank after I had it rewired and was wanting to check it before tucking it back into the dash. I put my left hand around the switch body to hold it still and turned the...
