    Ideal cylinder head temp range force 50 hp

    Typically, the thermostat for these Force engines is set at 130-~145 degrees while a few are at 130 degrees (usually 10~50 hp). The temp switch for the overheating alarm is set to 180~200 F. Which means the operating temp is around 145~160 degrees. Why not up to 180F?, well that is the set...

    85 hp compression

    As Jerry mentioned with 120# across all three, that motor is still good to go and can still run. I would surmise it is not running hence you took the compression. If you can post the steps you took for troubleshooting, then the group can focus on the remaining steps to take.

    Milky fuel in carb intake force 85hp

    On your next trip to the lake, try running the motor without the cowling cover and see if this makes a difference. And at the same time able to see the fuel filter if it stays at least half full. Other thing to watch for, the tower linkage movement with the carb ties and those wires that runs to...

    Milky fuel in carb intake force 85hp

    Great. So now we can rule out the fuel hoses, priming bulb and clogged suction fuel pipe. Have you installed a clear fuel filter between the fuel pump outlet to the carbs' inlet? This is a very good and cheap troubleshooting tool for fuel related problems. A $5 Fram G2 or G3 will suffice. Carb...

    Milky fuel in carb intake force 85hp

    This is a long thread. Anyways, when you did the Link and Synch, at WOT (engine off and control handle all the way forward) were the throttles (butterflies at the throat of the carb and NOT THE CHOKE BUTTERFLIES AT THE FRONT) at full horizontal? If they are, when you accelerate, does the...

    Where is the front line on trim tilt hydraulic pump

    Yours look definitely different. Probably, this is the one Jerry was referring to. Which is the more common type of T&T system.

    1994 120 force outboard no reverse

    So do you have Reverse and Forward now? If not and if the neutral position is between the N and R, then you need to screw in the lower shift rod more. Try screwing in the lower shift rod all the way in or until it bottoms out and then test again. The reason I recommend this is because the guy...

    1988 50 hp force no spark?

    So exactly what is wrong with the old stator? Was it burnt? Or could it just be a broken wire that can be repaired with a soldering iron? As mentioned, the original has 6 wires. But take note two yellow wires are twisted together and two blue (brown blue) wires are twisted together and only...

    tilt & trim

    If the tilt system is draining down, that also means the trim system is also draining. The two systems may have different names and purpose but they share the same fluid and pressures. So the solution as you mentioned is to replace those two seals in the valve body. AS MENTIONED BY TOPGUN DO NOT...

    Where do you get your parts?

    Last time I replaced three pistons (Wiseco) I used Master Tech Marine. I also get some parts from Boats.net and Outboard parts and also from iBoats whenever there is availability.

    1997 Mercury Force 120 - Loss of Power - Hard to Start

    The first two plugs look heavily fouled up. This is an indication of carb needing adjustment (too rich) or could be that the top carb needs cleaning. You can clean the plugs but I recommend replacing them. I had good experience with NGK's BUHW. Although, others prefer the Champion L76V. Be...

    1994 120 force outboard no reverse

    Was the reverse working before you change water impeller? If yes, you may have unscrewed the lower shift rod. You don't have to drop the LU unit yet. Instead, disconnect the lower shift rod from the upper shift rod. Now try to fully screw in the lower shift rod clockwise direction looking from...

    '87 Force 125HP ignition problem

    How did you test stator voltage output? With DVA adapter? Got a pic of the DVA adapter? Was the VOM meter on DC voltage reading with the DVA connected? Have you tested the DVA making sure it actually works?

    '87 Force 125HP ignition problem

    Really very surprising with so many bad stators back to back. And this is so baffling especially without any signs of overheating or rusting or broken wires. But you are correct with your readings.

    '87 Force 125HP ignition problem

    Just to make sure we are actually on the same page, can you post a pic or video showing the VOM reading (ohms reading) and which pair of wires you are taking the readings from. This reading is on an uninstalled or dismounted stator. Although stator do break, they seldom do. And if they do most...

    '87 Force 125HP ignition problem

    Was there any burn or overheating marks on the old stator that had zero output readings? Anyways, since you already moved on I guess you can use this as a training aid or even a spare if repaired.

    '87 Force 125HP ignition problem

    Well @jerryjerry05 once again, you were right; a "tested good" stator can be bad :) @Jiggz one thing stays a mystery, how when I disconnected the kill wires from both packs #1 & #2 started firing and that I tested it with VDA attached I got no reading?? This is why I recommended taking stator...

    '87 Force 125HP ignition problem

    Testing the voltage is across each pair of the blue and yellow wires. Using a DVA with the VOM set to test for DC voltage. You can test connected or disconnected but disconnected (both pairs) is the preferred method just to make sure no other interference. Just make sure none of the wires is...

    '87 Force 125HP ignition problem

    It's possible a separate winding from the stator is bad. To verify, with the kill wires disconnected from the terminal board inside the cowling, switch the blue and yellow wires (from the terminal board) and then check for sparks again. If the no spark switch to 1 & 2 (which previously have the...

    Trim motor

    Power is supplied to both green and blue wires to power the motor. The motor reverses based on which wire gets the positive and negative from the battery through two independent relays. The two relays does the switching depending on the Up and Down T&T switch. No electrical connection to ground...
