    90hp Force 1991-1992 starter

    Are the neutral safety switch engage? Measure the voltage between the thin wire terminal at starter solenoid and ground. When turning keyswitch to start position you should read 12VDC.

    85 force lower unit drain plug

    Try with heat from a propan torch around the allen screw and then try to drive it out with a small punch. Heat will help as the screw is made of steel and the LU case is aluminium alloy. The will expand different when heating. The allen screw has fine threads and if been in salt water it will...

    1988 50 hp force no spark?

    Maybe your multimeter has a DVA range. There are DVA multimeters out there on the market ... yes. What a DVA adapter does or actually contain are a capacitor a diod and a resistor. The diod rectifie the AC voltage and the voltage is then stored in the capacitor. With a regular VOM or multimeter...

    1988 50 hp force no spark?

    As jiggz says check insulation for the trigger wires to ground. From my experience the trigger voltage goes up to 2-5V but as jiggz says 0 Volt you are measure and 0,5V DVA is pretty close so a DVA adapter connect to your Fluke is needed to confirm if the triggers are okey.. As you mention you...

    1962 5hp sea king water pump

    Yes I think it will fit. But as this engine is a OMC engine move this thread to the Johnson/Evinrude forum. You will get better answers there.

    125hp lower unit change

    A dual exhaust LU will fit and work if it is a Force LU. Later in 1995-96 they changed LU to a Mercury style.. 85Hp was built until 1989 and in 1990 it became 90 Hp with larger displacement. I think the 90Hp had 2 piece drive shaft, the 85Hp did not. Maybe jerryjerry can confirm if that is right.

    1996 force 120 no spark top cylinder

    Look at outboardignitiondotcom, they have troubleshooting chart for the ignition system. I suppose you have the Mercury Thunderbolt ignition system as it is a 1996.

    1970 Evinrude 18hp Trottle issue

    Frustratedboater you need to change the range to a higher scale than your lowest 400 Ohm. The secondary winding has a higher resistance than 400 Ohm! At least 10-15 or 20 times higher than 400 Ohm.

    Chrysler 75hp, need direction.

    Set air/fuel mixture screws 1 1/4-1,5 turn out from seated. Start the engine and warm it up. Follow Frank A.s link and sync at top of this site. Check and adjust the throttle pick up point adjustment as Frank A. Dial in the carbs air/fuel mixture screw and set the idle RPM to about 1200 if you...

    Chrysler 75hp, need direction.

    Yes, firing order correct. You says it would not start unless in neutral and throttle all way forward. If I do not missunderstand you it sounds right if the idle screw at timing tower is not adjusted right. Maybe the throttle butterflies not open up at all when you throttle all way back. The...

    Chrysler 75hp, need direction.

    The gap at the timing rod block at my 1975 75Hp Chrysler is about 3/8 in (9,5 mm metric) at 30 dgr BTDC.

    1988 50 hp force no spark?

    Yes, then you have a short cut in the stator if it show zero Ohm.

    1988 50 hp force no spark?

    Okey you are using an analog VOM with a needle gauge. In what range to you have it when measuring. I suppose you can change the range from example 200 Ohm, 2000 Ohm (2 KOhm) and 20000 Ohm (20 MOhm).

    Prop size?

    The WOT RPM is a bit high but not bad. Be careful not over rev, if you go up 2 in in pitch the RPM would go down about 400 RPM.

    1970 Evinrude 18hp Trottle issue

    Secondary side of the coil (HT wire to one of the thin wires) should read about 5-8kOhm. You need to change the setting of you multi meter. If you have it at 400 Ohm range it will read infinity when measure secondary winding of the coil.

    1988 50 hp force no spark?

    When you says you have 0 Ohms do you mean infinity or short circuit. If infinity the stator is bad, there is an interruption in the winding. If short circuit the stator is bad too. Charge coil should read 680-800 Ohm at the winding and infinity to ground.

    Chrysler 75hp, need direction.

    Well you can check the flywheel key to be sure, but as the sticker 0-mark lines up with timing plate mark at TDC I do not think it is shared. I would suggest you to start it and check how it perform now. 30 dgr is in my opinion better than 33-34 dgr BTDC you had before.

    Chrysler 75hp, need direction.

    If you do not got the timing retarded when adjusting the timing rod there are something wrong. Check the zero setting of the distributor. Make sure with a screw driver that the top plug is at TDC and check it compered to the sticker. Is the sticker at TDC when the top piston is at TDC.

    Chrysler 75hp, need direction.

    As it is to the left of 32 drg right now it is more then 32 drg. Maybe 33-34 dgr. Retard it to 30 dgr or something around there 29-28 dgr. Try from there. The gap between the timing rod would be about 1/2 in at 28-30 dgr.

    Chrysler 75hp, need direction.

    Measured the gap at the block for the timing rod at my 1975 Chrysler 75Hp. I have the Magna Power I system with electronic distributor (optic diod eye instead of points). The gap is almost 1/2 in (12,3 mm metric).
