    120 hp 2.5 L mercruiser 153 ci carb

    Ya I upgraded to electronic distributor. I'll meter the coil when the key is turned over and see if I have 12. Thanks a lot for your help.

    120 hp 2.5 L mercruiser 153 ci carb

    Okay thanks. If I run a wire from the positive side of the ignition coil to the electric choke that would work correct? That way when the key is turned it's getting power. Also how should the actual choke be positioned, should I try dead center first? Or do I adjust it so it's 1/8 from closed...

    120 hp 2.5 L mercruiser 153 ci carb

    Okay perfect ya just cross referenced and it looks like the bR6ES is the correct plug equivalent for 73 and below. Thanks. Maybe it's just the right plug and have to adjust the electric choke and the idle air screw.

    I believe br6es is up to 1974 and after 1974 it's br6fs. Issue is I don't know if it's a 1972 or 1974 always thought it was a 72 Mercruiser

    120 hp 2.5 L mercruiser 153 ci carb

    Also my electric choke hasn't been working. It's a 1 wire but don't understand the grounding. Do I need to add a ground wire from the 3 screws on the plastic cover to the base of the carburetor? When I turn the key it instantly begins to heat up

    120 hp 2.5 L mercruiser 153 ci carb

    Hi guys I have a Mercruiser 2.5 L 153 ci 120 HP with a carburater I bought off Amazon. It has worked great for me but my spark plugs get pretty black and fouled and then it starts to run crappy after a while. Can someone point out the air/fuel idle screw so I can potentially adjust it to not get...

    Mercruiser 2.5 L 153 ci 120 HP alternator

    Hi guys I have a Mercruiser 2.5 L 153 ci 120 HP. The alternator on it I believe is for a car engine and not marine rated. Can someone confirm with the picture below? Also if it is a car alternator could you potentially give me the proper part number for a marine rated one. Thank you

    It’s 14 feet of jacket and adding the 30 inches brings me to 16.5 feet which is labelled on it. My steering wheel moves perfect without the flat gear attached. Am I okay to go ahead and buy a teleflex cable that has the same flat gear that mounts to the steering wheel? My only concern is the nut...

    Perfect thanks for your help. Is the nut that holds the steering cable to the back bracket of the picture I posted above usually the same size? Could I just order a teleflex rotary system and buy a new rotary steering wheel? As long as the nut is the same size it should theoretically work no?

    Ya as far as the shift cables go the two brown wires weren’t connected to my ignition coil so I’m going to try that out. As far as the steering goes the cable is black and it’s 16.5 feet. The helm is straight. I took apart the cable at the back and unseized it but it’s still very tough to turn...
