    Force Chrysler 35 hp, pistons.

    Vagelis try Franz Marine, he might have pistons and rings. Yes he is in the US so you have them shipped to Europe and I think he is the only solution for your engine.

    '95 Force 120 - bottom cylinder not firing

    As you says it is a 1995 year model I think it has the Mercury Thunderbolt ignition system. Earlier engines had the Prestolite system (two blue or black CD boxes and four blue or black ignition coils). All these parts mounted on a plate at star side of the engine. The Mercury system has one...

    '95 Force 120 - bottom cylinder not firing

    Start with checking compression and spark at all cylinders. Clean spark plug could be no spark issue, water intrusion in the cylinder etc. Compression should be 145-150 PSI but down to 120-125 PSI it will run decent. Most important is that the difference between the cylinders are not more the...

    Street Fire Ignition controller instead of Magnapower II

    I have done some convert from Magna Power I ignition (the head of this thread is wrong. Magna Power II is a different system) to automotive typ ignition. It works great if you maintain the points regular cause the points is a part of the ignition in another way then in the Magna Power I CD...

    1995 90HP Force Outboard Fuel Starvation

    Thank you pnwboat for the eminent explanation about the air/fuel idle speed settings impact at higher RPM and WOT. There are many folks that has questioned me about this theory and I have not been able to explain it. I asked Frank A about this a long time ago in this forum but he did not have...

    Thanks to Jerry Jerry for all of his advice. Merry Christmas

    Jerryjerry I have bought pistons with rings from Franz Marine. Most of the pistons OEM and Wiseco brand. Seals are also available from Franz Marine and Sierra. For one of the blocks that I am going to restore in this winter/spring, I will try to use Vertex pistons. Have just order three pistons...

    1971 Chrysler 20 HP Coil Wiring

    Stewart, I will take a look tonight under the flywheel of one of my 20Hp Chrysler an see where the grounding of the coil is situated. As I mentioned before both thin wires from the coil can not be attached to the points terminal. One should be and the other should be grounded. Otherwise you do...

    1971 Chrysler 20 HP Coil Wiring

    There are four or five (I do not remember) screws that hold the magneto stator ring to the stator plate (timing plate). One of those has a wire for grounding the stator plate to the block at the fuel pump. Use one of those screws that hold the magneto stator ring to the stator plate or use the...

    1971 Chrysler 20 HP Coil Wiring

    Stewart, the thin wires are the prime winding. One of them are the common wire for the prime and the secondary winding. The common wire should be connected to ground and the other connected to the points. If both thin wires are connected to the points you newer will have spark. You can measure...

    significance of same cylinder-pressure

    The force power I think it will act as pnwboat second explanation. It will run with a bit lower performance but will last for many years if you maintain it well. A rule of thumb is that no more then 10-15% difference between the cylinders. If more, there will be problem to tune the engine and...

    1967 Sea King 6hp - Low Compression

    Logan that is not a hole in both pistons! That is the pin which stop the piston rings to rotate. This is normal, look at the cylinder walls for score when the head is off. Maybe the rings are stuck from carbon build up.

    1967 Sea King 6hp - Low Compression

    As racerone says it is a Chrysler, but it is the early model of the 6Hp Chrysler. In late 60.es (1968 I believe) there Chrysler introduce some small low profile engines and they were in many different Hp ranges during the late 60.es and the 70.es. From 4,4Hp up to 7-8Hp. Many parts fitted all...

    Starter engages the flywheel but won't spin the engine

    Winner if that is the starter that came with the engine from factory I would say it is a premium quality starter, maybe Bosch or Prestolite brand and I should rebuild it instead of buying a new cheap Chines crap starter. If the commutator is not to worn you could do it your self otherwise leave...

    Starter engages the flywheel but won't spin the engine

    Winner74 it sounds like the solenoid is bad. Bad connections inside where the "switch" actually a copper bar is closing when activated. It also can be a bad starter, but as you have only 8,5 Volts at the starter positive terminal there seams to be a voltage drop at the solenoid. If you have the...

    Starter brushes

    I do not know the length of the brushes when new but yours seams to be able to work well for some years more. Maybe there is a minimum of the length in the service manual, do not have it for sure in my mind. In my opinion it is time to change them when the length is less then 25-30% of a new...
