    Motor-Guide 2600

    Hello. I have an older motor-guide 2600 and can't find a manual or information on web. My main question is what voltage is this motor. I believe 12 volts but can't verify and don't want any damage. This unit has a foot pedal control with switch on top and a 3 position toggle switch on pedal...

    73 t/bolt 650 reverse

    I'm having difficulty with reverse. On the controller there is a detent position for forward and another for reverse. I can't shift into reverse with controller but when I shift into reverse manually with cable removed my prop turns in reverse when moving flywheel. Still trying to figure out if...

    Reverse lock-out shaft

    I have a 1973 Thunderbolt 650. The shaft that raises to engage reverse lock when shifting into reverse ( that prevents engine from raising when in reverse) may be bent. I can't find a picture anywhere to compare to determine whether mine is bent or not. If you know the real name of this part I'd...

    73 Thunderbolt 650 push rod guide orientation

    I need to know which way is up for the push rod guide. In the attached pic, I have the end that you see facing down. It appears that inverting this piece would work as well but if I do, the top of the shift cam will push into the guide and it would add even more friction when shifting. My manual...

    73 thunderbolt 650 kill switch wiring

    I'm trying to wire an add on kill switch to a 1973 thunderbolt 650. The original owner had it wired to either short or open the brown (tach wire) on the switch box. I've since learned this does nothing. I'm sure I could wire it to open the white/black trace wire coming from the distributer but...

    73 thunderbolt 650 brown wire

    Thanks for the response. My understanding of the add-on kill switch wiring was to ground or remove ground to the tach wire to kill the ignition. Be that right or wrong, until I figure this thing out, the kill switch will remain disconnected. Yes, I do have the 8 bolts holding the flywheel down...

    73 thunderbolt 650 brown wire

    Thanks for the quick response. I wanted to upload a switch box pic to further explain. The blue wires on the right side of pic go to the coil and are ok. The brown wire to the left is the one I have question about. It is the tach wire and it goes to the kill switch only. I believe this is a...

    73 thunderbolt 650 brown wire

    Hi all. I have a 73 Mercury thunderbolt 650. The engine cranks but won't start. When cranking the engine remotely with key on and plugs out I have a very strong spark from each plug wire separately (cranks well with key too).I've gone through the carbs and all seems fine. I do have a kill switch...
