    So i decided to pull the powerhead off....

    If the cylinder walls are good just put new std piston with new rings in and hone the bore. As racerone says the std bore from factory is 3,312 in. You will find pistons and rings from different web sites such as this one, Master tech Marine and a lot of others. Best source in my opinion is...

    Chrysler 75 hp. Difference in spacer plate to same motor?

    ErSa, it is a water cooling jacket as I said when you where at my house. I have had some issues with some small leakage at that surface after reassembling power heads. It wants to drip some water there. I do not know why they change it during Force brand, maybe because they stop with the by pass...

    Chrysler fuel pump

    That pump will fit, but as racerone says pull your apart and check the diaphragm. OEM diaphragm is F438747 and gasket 820490 (F438760) Sierra aftermarket kit which includes some other gaskets too is 18-7806-1. BTW: I see you have the DELTA CD box and the ignition coil is not the OEM. My...

    1977 Chrysler 10hp 100HA cowling

    If it not is an autoelectric model and in 1977 I think the autoelectric model was not in production that late all hoods for previous 9.9, 10, 12.9 and 15Hp will fit. Maybe the 12,9 and 15Hp do not fit, to big. The autoelectric model had a top arrangment on the hood for the dyna starter. It did...

    1965 West Bend by Chrysler

    That is a 4 cylinder West Bend Tiger Shark 80Hp. Maybe it is a 1964 or earlier. I would suggest you to contact Franz Marine. Maybe he will be able to help you. Nice engine and I think they are rare. I have only seen one here in Sweden and it was in a pic.

    You can use all Chrysler remote controls and US Marine controls up until 1994-95. Then Brunswick started to put on Mercury LU and ignition system. The remote controls then had Mercury style connectors.

    Tachometer for 1974 135hp

    Jerryjerry the ignition system Winnercougar has in his 135Hp is the battery driven Motorola CD system. The stator is only charging the battery and the white wire that is for the tachometer is a signal from the CD box. I think it is the same signal as the signal to the ignition coil but do not...

    Tachometer for 1974 135hp

    First of all automotive tachometer are for four strokers, your engine is a two stroker. The two stroker is firing at each revolution of the crank shaft the four stroker at every second revolution. If the tacometer you try to use take the signal from the low voltage circuit of the ignition coil...

    1978 Chrysler 85HP Powerhead Swap

    Okey, there you are. Franz Marine is the best source but not the cheapest. I do not know where you somewhere else can get warranty (but I am in Sweden so I do not know all suppliers in the US), maybe Mastertech Marine.

    1978 Chrysler 85HP Powerhead Swap

    Topgun, yes I am talking about the length of the drive shaft. No there are no stampe or other marks for the ratio. Best way to check it in my opinion if the LU is not apart is to turn the drive shaft one turn and check how much the prop shaft turn. If ratio 2:1 the prop shaft turn half a turn...

    1978 Chrysler 85HP Powerhead Swap

    Topgun and The Force, all 1 piece gear case from I believed 1977-78 when it was introduced up to about 1994 when Mercury started to put their Mercury LU on. You can put a 2 piece drive shaft LU on, it will fit. The 2 piece drive shaft LU came at Force engines in 1989. I think there was three...

    1996 Force 120 with crazy compression numbers

    Those number do not sounds so weird. OEM factory service manual through 1991 A models call for 145-165 PSI for the 120Hp. It can be the gauges that shows incorrect values, but in my opinion it is pretty normal. I have two Chrysler 45Hp "super sport" that was ligthly "hotted" from factory with a...

    Idling

    Agree with both Scott and Racerone, maybe the carb/carbs needs a cleaning. Change fuel filter and if no filter, add one between the fuel pump and carb/carbs. Todays fuel are not as good as it was before, with a lot of ethanol in it, it absorbs water. Fuel that sits for a while become bad and it...

    Force 125 1988 Water drains out the exhaust

    ggausa, as racerone says you need to get the water level above the impeller housing. The impeller is not self priming it need water in the impeller housing. When running in a bucket you need a deeper bucket, the water level need to be about 4-5 inch above the LU split line.

    Force 125 1988 Water drains out the exhaust

    When you run it, did you run it with muffs or in the water? When running on muffs your are just able to idle cause the water flow from a garden hose do not deliver the amount of water the engine need. The impeller produce more water flow then the garden hose can deliver. When running with muffs...

    98’ Mercury Force starting issues

    Sounds like a bad battery. Do as pnwboat suggest check all power connections and keyswitch. Maybe you have a bad regulator/rectifier and when the battery have sit for some hours it is able to start the engine but the charging system do not charge the battery while running. When you then try to...
