Where did you get the replacement solenoid ?-----And be very careful when you start guessing on what wire might go where.-----Find a wiring diagram before you hook up anything.
Post some pictures of crankshaft , connecting rod bearing surfaces when it is apart.-----Look for freeze damage too.------Perhaps engine drain plugs were not put in by previous owner.
Some will argue.-----A compression test is always step #1 on these crossflow engines.----Post the values you get.-----On muffs----" in gear " ---Is still neutral and that test means nothing !
Motor has to come apart now.---All crankshaft / rod bearings are likely damaged from water exposure.-----Or if you get it running it will come apart by itself !-----Need parts the----evinrudeparts.ca -----may be able to help.
Some will argue.-----Take the motor out.-----Take motor apart for inspection.---Could be freeze damage on block and muffler.-----Likely you will find lots of corrosion on the precision crank , rods and bearings.
Trouble shooting starts with a compression test.-----Just had an enquiry from someone 3-1/2 hrs away asking for help with a crossflow 90 HP and compression issues.
The powerhead is a JOHNSON / EVINRUDE outboard.-----With some fuel system mods as it is regarded as an INBOARD installation.-----Done as per coastguard rules.----Turbo-jet is the name plastered on the powerhead / pump package.-----It is a crossflow motor.-----Loop charged motors use aimed intake...
You are making it difficult for yourself !!-----Not sure why simple wiring is not well understood.------You have to connect the red from the motor to the red at the control.-----You have to connect blue to blue.----Green to green.----Done !
???----Cut the plugs off!!-----Connect the wires with some convenient easy to find plugs.------Like wires for your toaster.----Or a terminal strip with simple connecters.
Take it apart and look to see what you actually need !-----Did a carburetor cleaning on a 15 HP earlier this year ( northern Ontario ) no parts used.----Runs like a top once more !
Sounds like you are.------Find the other plug in on the motor.-----Big $$$ from factory.----I have used ordinary 3 conductor wire to make one.---Cut off plugs and solder wires.
