for that year of manufacture 4 strokes were not the normal thing in outboards if it doesn't have rocker covers and rocker gear it is a 2 stroke

Hey Sam.. Here's what you need.. Find 1993 Johnson VJ225TXETA 225hp Outboard Motor Parts by Engine Section

need to notify them fixya doesnt have access or is affiliated with them

Hey William, Could it be possible that the model number is FD-17? If so, its a 1963 18HP. If this is not right...?? ....These numbers you give do not show up in the records..

Its a 1982 model.

coil for that plug would be wort checking

Hey George, try here.. https://www.marineengine.com/

it sank..ooopppsss...sounds like trouble.. First thing I would do is check the compression with a gauge... This will require a GREAT friend.. remove all the spark plugs - makes PULLING the engine over easier.. get a compression gauge (or take it to a competent professional to get the compression checked!). Install the compression gauge... Put the throttle wide open... have your buddy yank with ALL his heart about 6-8 times..it should show about 115psi+ minimum..all 3 cylinders should be with 10+-psi. If they are not at these specs minimum..you have found the issue..then try putting a little outboard oil into all three cylinders and repeat the test.. if the PSI goes way up.. you have found the issue.

By reading this.. I am assuming #3 is the crank battery.... Try this.. (from experience) remove all wires (or big terminals) from the battery and see how that works.. I have a 3 bank and use a stand alone charger!! Works BETTER!!!

Do you remove the trolling motor wires before charging..? ...If not.. try that......mine started taking a LONG time to charge.. after I remove the trolling motor cables.. it take less time and charges better!!!

First. the +/positive/hot wires go to the respective/separate +positive/hot side battery terminals.. and the -/negative/ground wire go to their respective/separate -/negative/ground battery terminals. The wires from the charger are "paired out".. meaning the + and - pair must go to the same battery. .. you can't mix and match.

I am soo sorry... Prayers for you!

One is fuel, one is vacuum.... more trouble than its worth.. (I had one!)..sold it when I had to pump and pump and pump...and pump....and pump...

Make sure your battery is GOOD and holding 12+ volts! ..You have a hot wire from the battery to the solenoid. You should have 12v at that terminal. Use a multimeter - set to 12+dc volts and check the voltage.. + on the solenoid terminal and (-) negative to ground. If you are getting 12volts to the solenoid, and its not starting.. you need to check for a bad solenoid. BE CAREFUL.. SPARKS WILL FLY WHEN YOU JUMP A SOLENOID... GAS OR GAS FUMES WILL EXPLODE!! You need to "jump" the solenoid,, you can use a decent side srcew driver to connect the two large threaded studs(terminals) on the solenoid. when you connect them (sparks will fly - be careful - have a fire extinguisher handy). the motor should turn over! If it does turn over - get a new solenoid, if it does NOt turn over you need to trace voltage back to the battery.. A bad battery could show 12 volts and ALMOST ZERO amperage.. not enough to even make the engine do anything... Do all this and repost.

I think you are missing some letters/numbers? I do not see that serial number. That may not be the model identification number.

OUCH... ok.. do not try to start it again.. you can and will cause more damage! Is it in gear when you are turning it backwards or trying to make it run? (need to eliminate drive line issues) How long with it run after you turn it backwards? ..will it actually run or just turn over? (turning an outboard backwards will damage the water pump impeller!!)..its something you need in perfect working order! Remove the spark plugs.. see if there is anything on them except a little carbon....We are checking for damage to the piston/rings area. If there is anything on them but a little carbon, you have found the problem area... If they plugs are clean, (and NOT new).. then you need to check further..You will need a GOOD mechanic to help you.. I would pull the flywheel to make sure you don't have any broken magnets/stator damage. If the issue is NOT in the lower unit...then its in the power head. Take it to a professional mechanic. Repost/reply with more info on what you have done.

Set the motor on the transom and make sure the cavitation plate is below the bottom of the boat.
