    1989 85hp WOT only 4300rpm

    As jerryjerry says check the prop, what size (pitch) and check the load. Force 85Hp 1989 should be equipped with Prestolite CDI ignition two CDI boxes and three ignition coils (black or blue color). One thing you can do if you have not done it is to check all the lugs under the shrink tubes for...

    Finally Had To Retire It

    Too bad to bury a Chrysler/Force 50Hp engine. Sad that I am in Sweden Europe. Have a lot of impeller housing that would fit and work for a lot of years.

    Gas spewing from Carb

    Dumps a lot of gas through the motor? Are you running it on muffs? If a lo of gas is coming out through LU (exhaust snout) probably the fuel pump diaphragm is bad. And yes as racerone mention "kick the secondary butterfly"? These engines has two butterflies, first one you see when you looking at...

    Throttle cable maintenance and adjust basics? Force 85 H.P. or other..

    There are four adjustments for the carbs from the outside. 1. Throttle pick up point adjustment. 2. Throttle butterfly opening. 3, Idle screw setting. 4. Air/fuel mixture setting. When setting the carb you first start with the throttle pick up point adjustment and then the throttle butterfly...

    1986 Force 125 hp popping

    Do as roscoe and raceone suggest, check the flywheel key. You do not have to remove the flywheel to check it. Set the throttle at idle (lowest setting as possible). Put a screw driver in top cylinder and turn the flywheel to set #1 piston at TDC. If the key is okey the timing mark should line up...

    Force 507X8B Ignition

    I have looked at it closer and it seams like you have wired it correct. So some questions then. The brown wire at the new CDI box, where have you connect it and does the new CDI box have any black wire? From the diagram in #4 by The Force the CDI box should have a ground wire (black) and the...

    1989 Force 35hp fuel pump issue

    The pump pnwboat refer to will fit your engine but you have to remove the adapter spacer #4 in the schematic, part number F658836. The pump body, the diaphragm and gasket is the same for both the 35Hp and 40Hp. BTW the pump body, diaphragm and gasket are the same for a lot of Chrysler/Force...

    Fuel pump 1988 force 125hp

    The pedals should rest at the V-block surface without any gap. Well you could accept a very very small gap but not more then 0,003-0,004 in, in my opinion. Dead closed is the best. Each cylinder has a V-block with two sets of reed valve blades. One valve blade at each side and each valve blade...

    Fuel pump 1988 force 125hp

    From the pics it looks like the diaphragm is bad, but it can be a reflection in the pic. Usually the other parts in the pump never goes bad, just change the diaphragm and the gasket then it will work. You mention that the carb is spitting fuel. I would suggest you to check the reeds, if some of...

    Chrysler Engines

    Yes you can pull the 105Hp head and bolt it right on the 140Hp leg. The bolt pattern are the same. The different between the 105Hp and the 140Hp is the bore. 105Hp has 3,312 in bore, the 140Hp has 3,375 in bore.

    Leaky lower unit?

    When running at muffs you will see some of the cooling water coming out of the drain holes in the LU. But in this case it looks like there is a crack or a hole at the attached screw. You have to look closer at the screw, the water impeller housing should have a plastic seal tube, part number...

    1990 Force 90hp 3 cylinder won't start ughh

    Okey if you are unable to pull off the remote control box you can do as pnwboat suggest. If you look at Maxrulesdotcom (Mastertech Marine) web site they have wiring diagrams for Force 120-125Hp thru 91A. The different in the diagram is that it is a 4 cylinder engine yours is a 3 cylinder engine...

    1990 Force 90hp 3 cylinder won't start ughh

B...power (12VDC) C...choke S...start I...ignition (in some set up or 12VDC in running position to feed auxiliary objects in some set ups) In your set up the...

    1990 Force 90hp 3 cylinder won't start ughh

    I think that jerrjerry is wrong in this case about the kill switch circuit. If the engine has the Prestolite ignition system (my sons 1988 85Hp has it and in 1990-91 they started to switch over to Mercury style ignition system) three blue or black ignition coils and two blue or black CDI boxes...

    1990 Force 90hp 3 cylinder won't start ughh

    You need to check if it has spark at all three plugs. 60 PSI compression is way to low but as you says it has 60 PSI at all cylinders it might be the gauge that shows to low numbers or you have not spin it over long enough. The good thing is that all three are even. The compression should be...

    89' Force 50HP low compression.

    Later Force engines had a tendency to brake piston rings cause the land for the top ring was to small. It could also be carbon build up at the rings. The rings could be stuck by carbon build up.

    Startup procedure

    This sounds like a good start up procedure. Remember that OBs are different individuals, some engines need another start upp procedure. My youngest son has a 85Hp Force 1988 and he do the same procedure almost always. My rule of thumb is when warm do not use the choke at first. If it does not...

    55 hp Chrysler. Model 5551 has 3 piston rings

    As jerryjerry says the older 55Hp btw. also the 35Hp and 45Hp had 3 rings. I think about prior 1973-74 they had 3 rings. The head gasket was the same for a long time and you can not identify the year by what head gasket fits. To verify the year you need the model number, the serial number is...
