Have the exact motor hey buddy how are you doing have. a question?? any tips about we’re to get engine wires you replaced the harnesses let me know thank you
I have a 1975 850 mercury. Went through the same thing with the wiring. Installed all new wiring and control box, distributor/ trigger, rebuilt carbs and fuel pump. Runs like a top now. 35 mph on a fiberglass bass boat. Keep trying, you'll get it going.
I'll Say This Much. Old Thunderbolts ALWAYS had starting problems. My Grandfather had an old '81 Model 800. It Almost became a Gag. It's Like "She Always Has Problems but She Always Runs". Personally I Find It Gives 'em Charm.
yep, when I bought mine, the guy turned it over for a few seconds and it ate the impeller, i COULD SMELL IT, I told him Ill give you $200 less now as I have to fix the impeller
Remember that Motors been sitting a long time so that's not likely any oil on any of the cylinder wall so the best thing to do is pop spark plugs out shoot it full of a little mix STP and and two cycle mixed gas and let it sit for a day or two and then come back turn over light handle little bit let it sit for longer shoots in the world in a cylinder make sure they're lubed up good so it doesn't tear itself up when you started
Not familiar with boat engines but it your battery is good load test it to be sure then find the solenoid and power it there if it still clicks tap the starter motor with a hammer if it still just clicks it is probably a bad solenoid or starter, the contacts in the solenoid get corroded from arcing when it closes some solenoids can be takin apart and cleaned or the starter bushings could be warn and that causes a loss of power to turn it over, just a few thoughts good luck. When you hear the clicking that is the solenoid magnetically closing to contact the copper contacts that send power to the starter to turn it over.
Dude I have the exact motor and I'm about to start the same job, all the wiring was crumbled apart, my only snag is that the wires corroded all the way up to the stator.
That is exactly what mine is doing one click from the starter solenoid each time i turn the key, bought a new inside wiring harness installed, same thing one click, got a new starter solenoid coming in the mail but i really suspect it is my wiring job at the ignition switch, i think i got it wrong and i can't find a dang diagram for my year/serial number 1969 650 four cylinder
I repaired same engine, the problem with not turning on key turn was bad wiring connection to the battery, i dont know how you got lucky on tapping on starter because thats not how you fix a starter :D. The problem was in the wire going to the batter for me and after that no clicking and turns in first time everytime.
I got it running! th-cam.com/video/QI3drHO39jc/w-d-xo.html

@@coutryoutdoors3662 I used generic 12 gauge copper wiring that i had in the garage, I think it was from princess auto, it's a little thicker than oem

You likely did damage to the Water Pump Impeller starving it of water in that mini bucket.
Boat looks like a late 70s Crestliner Muskie 15

clicking means no power from battery
I just bought one of these and nobody will work on it. I need help
