    Chrysler 75 hp 1975 Spacer plate?

    1988/89 Force did away with the pressure relief/ poppet valve. They found it would get stuck real easy and in salt water became useless real fast. It was located on the bottom of the block. Diamond shaped cover with 2 TINY screws holding it in place. They moved the pressure relief up in the...

    1975 25HP thermostat

    The reason you can't find one is they made a place for one but didn't use one??? Lots of smaller Chrysler/Forces didn't use a thermostat.

    You said: "getting a sort of a half-second slip and thump as if the clutch dog is periodically slipping." It's possible the dog is slipping?? Also test the prop hub for slipping, Remove the prop, scribe a line across the hub and reinstall and go for a ride. After a slip, check the scribed line...

    On the block under the coils/packs is a foundry stamp. The numbers in the middle of the circle is the year. Also under the bottom carb on the intake is another foundry stamp. Sometimes the starter will have a year on it(if it's original). The comp #s : that motor was designed to have a...

    Force 120 1976 - Was running great, then gradually lost ability to idle. - Need Help Please

    Before you remove the head: get a snake camera for your phone and have a look at the cylinders or a long skinny screwdriver and turn the motor so the sd goes all the way in and see if you can feel any cuts or grooves in the walls. The spark plugs all burning the same or is #1 clean? Pics? How...

    Force 120 1976 - Was running great, then gradually lost ability to idle. - Need Help Please

    I answered this in the post you hacked. Always start your own. The motor in the video is from a 120 Force about 1995 The coils /pack are a Mercury added part, they took over about 94 and used their parts. From the way the motor sounds it sounds like the carbs are set wrong, one running faster...

    Chrysler 1981 55HP Possible CD problem

    You said: Was getting it ready for the water so was double checking the timing and that's how I noticed it as the timing light wouldn't show the markings as it warmed up. The Force/Chrysler timing marks: the timing is set at wide open throttle and not running. If you get it running and search...

    Chrysler 907HB 90hp wiring color codes…

    The worst thing about the Chrysler/ Force is the gas economy. No where as good as the newer motors but not that bad. My neighbors 225 Evinrude cruising got about 2.1-2.3 mpg. My twin 88 85 usually around 2.3 mpg, not too bad. The newer EFI/DFI get a whole lot better. Friends 2007 200 Yam OX66...

    running rough at idle

    Try the starting fluid test?? Start motor, spray SF around the intake side of the motor, around the carb bases, under the ignition components and around the port covers. A miss like that can be a bad gasket under the port cover that holds the fuel pump or the other cover. One small backfire...

    I really doubt you'll find a sending unit :( When the trim extends and touches the mid section there is a plate that fits in there so it doesn't chew up the soft aluminum. It's NLA from most parts places but ebay or Franz marine might have it??? THRUST BRACKET F449354
