    How do you choke tat motor? Do you push the key in? How did you check for spark? Have you done a compression test. You need to buy the factory manual for your motor

    2006 Mercury Optimax 175 issues

    That's a bad motor to not have the funds for as parts are generally expensive. First thing to do is buy the factory manual. You need to see if it is storing any codes. But a good bet is the motor is the reason it ended up at auction.

    Does the switch box impact the rev limiter?

    5250 is tops for that motor. Anything above 5500 you risk broken piston skirts. Like I said thevrev limiter is normally on the jets not the props.

    Mariner doesn’t go into forward or reverse.

    I thought that was an American made Mariner. My fault but that motor is worse. The Yamaha made Mariner has next to 0 parts support for that motor get your money back. Don't even bother taking it apart get your money back. Hopefully you did not pay a lot for it.

    That should not have been on the front of the motor. The negative battery cables and all grounds are attached on the exhaust plate of that motor. You need to have the negative battery cable attached to the block.
