    1988 50 hp force no spark?

    When you receive your CDI stator it will come with instructions and diagram. And you should follow it to the letter. With six wires you have the option of either putting two wires of the same color (Brn/Yel to Brn/Yel; Brn/Blu to Brn/Blu) together or just using one of each colored wires (except...

    Milky fuel in carb intake force 85hp

    No gasket seal or maker needed. Just make sure it's clean and mating surfaces are not warped.

    1988 50 hp force no spark?

    Well it's great to know it only has 4 wires, 2-blue wires and 2-grn/yel wires. If you read zero ohms between the blue wires then that stator is shorted. I'm presuming you at least had one wire disconnected from the terminal board before taking the reading or better yet all wires disconnected...

    1988 50 hp force no spark?

    Did you try reading between a blue wire and a yellow wire? Based on the original schematic, there should only be 4 wires from your stator. 2-Blue Wires and 2 Green/Yellow wire. If there are six wires then that stator is not the original stator with 6 wires there should be 2-Blue, 2-Yellow and 2-...

    1988 50 hp force no spark?

    Nordin got it all correctly. With the flywheel off check the resistance of the stator charge coil, between wires bl/yel or bl/bl and it should be around 680-800 ohms. If you are getting this resistance reading most likely the stator is still good. Now check continuity of wires from stator to...

    1988 50 hp force no spark?

    Sometimes, lost of total sparks on all cylinders could be as simple as the safety lanyard being activated. This is a lanyard that is supposed to be worn by the driver and if he happened to be thrown overboard will activate the shut down switch, hence stopping the motor. Disconnecting the...

    1995 Force120 Picture help diagnose

    When you removed the head did you inspect the cylinders for any scratches or gouging? The bottom 3 cylinders are too clean for a properly working 2 stroke engine like this one. Unless you already cleaned it prior to the pic. But the top one is too carbonated. How do the plugs look like? What is...

    50 hp force questions after recent test run

    Hydrofoils do help in preventing the bow rising too high by pushing down on the water to keep the stern up. However, there's no such thing as free lunch, for the payback is in lost of speed. Not a whole lot but you will lose some top speed.

    50 hp force questions after recent test run

    The wetting should happen pretty quick. The discoloration may take awhile until you do the long runs. But with wetting, rest assured there's enough lubrication in the cylinder.

    50 hp force questions after recent test run

    With new plugs, you need to ran the motor (hose and muffs) on the driveway idling and a little short burst not to exceed 2000 RPM. Ran it for about 3 minutes. If you have starting fluid try spraying it into the carb adapter (do not let it in to the mouth of the carb), transfer port covers, etc...

    50 hp force questions after recent test run

    24 MPH at WOT is not bad at all especially for a tri-hull boat. A tri-hull provides more stability on the water but at the cost of more drag. So I say 24 MPH is decent. As for the air/fuel mixture screw, 1 1/4 is not bad. Do an assessment again after switching the plugs. If the bottom cylinder...

    50 hp force questions after recent test run

    If it went past the reeds, it'll just burn up or it can get stuck with the fuel recirc system. However, since the motor seems to running fine, it probably just burned up. Now if the motor is misfiring it could be jammed making the reeds open.

    50 hp force questions after recent test run

    Yes, when you clean the carbs and dismount them, remove the intake adapter as well and with a flash light you can clearly see the reed valves. As for the foam, if you don't mind the noise no need to replace the decaying foam insulation. But if you do want to replace it, the late Frank A...

    Ideal cylinder head temp range force 50 hp

    One disadvantage of the water pressure gauge is if you use your boat on salt water. That 1/8" tubing just gets clogged up with salt build up. I have to flush mine after the season using air and fresh water to de-clog it. However, if you just use your boat on fresh water like lake, it's perfect.

    Ideal cylinder head temp range force 50 hp

    Looks like a good thing to have to monitor engine temp. I did install a water pressure gauge on the top of that t-stat housing and seems to be working perfectly. I do not have the tell tale instead what I see is water pressure ensuring the impeller is doing its job. Let us know how it goes with...

    Milky fuel in carb intake force 85hp

    "It ran better . . ." does that mean it ran fully at WOT? or at least attained 4000 RPM? If so then the problem could be exhaust leak. But it is rather hard to diagnose exhaust leaks on the driveway unless you are using a large barrel of water. Using a garden hose alone will not identify the...
