    1984 force 125 low compression question?

    All the mating surfaces will need to be sealed.....or it will leak. High heat RTV will be good.....just don't get crazy with it.....any excess will squeeze out and could clog up the water passages.....

    What is this part called on Force 125

    There is no idle timing spec on Force engines....timing is set at WOT. Yamaha is a different animal.... Might want to fact check your info before stating that somebody else's info is wrong.....(y)

    1984 force 125 low compression question?

    Head gasket is put on dry.....if you removed the head cover it will need to be sealed with RTV, as there is no gasket there. Glad you didn't run out and buy a new fuel pump, as was mentioned earlier.....Lol.

    1984 force 125 low compression question?

    If it works (pees water out) I would leave it be.....gives you a visual that your water pump is working. A lot of owners have added a telltale if it didn't come with one originally.

    I have dual batteries on my truck....passenger side has 2 positive cables and had the same problem keeping them tight. I got rid of the crappy GM battery bolts and used 3/8 course thread bolts/nuts to secure the cables. Works really well and no problems since.....thought I would pass this...

    Think you got lucky there.....cyl#3 looks good in your pics, from what I can see. How many head bolts broke off?

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    The impeller spins clockwise .....this pic is what it should look like from underneath.....with impeller mounted in the housing, flip it over and slide down the shaft and engage the key in the slot. The carb leaking from that hole......could be the float needle not shutting the fuel off and...

    1984 force 125 low compression question?

    Well, I believe jerry knows what he is talking about....and I agree with him that the fuel pump will not cause loss of compression like the OP is seeing......that's my take on it.

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    The torque spec for the pump housing bolts is 70 IN LBS....or about 6 FT LBS....think maybe you cranked it down too hard?

    spin-on gas filter

    If the filter will be totally exposed, then roscoe is right.....the all metal spin on would be the better choice.....and fuel flow shouldn't be a problem either.

    spin-on gas filter

    All it is is money.....am no expert, but you don't want a filter that would cause a problem with fuel flow.....not sure how strong the fuel pump is on your 9.9hp.....it will have to be able to suck fuel through whatever filter you get.

    The oil is in solution.....it cannot be filtered out. (y)

    spin-on gas filter

    Shouldn't need a water separator filter on a portable tank as you can just dump it out if water gets in there. Hard to do with a built in tank. It could work but the filter would have to be mounted somewhere in a vertical position in the boat, then connect your portable tank to it. Probably...

    1984 force 125 low compression question?

    It's your motor you can do what you want......WD-40 is good but I don't think it will fix your compression problem. 30-40 PSI tells me it is time to take a look.....snake camera in the plug hole or remove the head. It won't hurt anything to try the WD-40 and find out for yourself if that will...

    1984 force 125 low compression question?

    Back firing could be a timing issue.....maybe a sheared flywheel key. I would not run it again until you figure out what is going on with the low compression on cyl#3....that is a known problem that needs to be addressed first.

    1984 force 125 low compression question?

    Was referring to the gasket leaking....uneven or too much torque can cause the gasket to leak.
