    88 Cobra 5.7 alt/ps belt numbers?

    Does anyone have the belt numbers for the alternator and power steering off hand? No dice in my factory manual. I found some through Sierra but they listed as the king cobra. I can look on the boat when I get home, but I kinda wanted to order them now to have them this week. Thanks

    OMC cobra top mount control swap out

    Hey guys, in overtaking the Donzi restoration, I feel that the OMC side mount controls are rather dated. I want to upgrade to a top mount twin control (one for gear and one for throttle) Is such an option available for the OMC Cobras Circa 1988?

    Cant read my Carling contura 2 switches in the dark???

    So I bought all new switches and decided on the contura 2 with independent illumination. I figured I would hook the lights for the switches to my nav lights so I can access them in the dark. Well, in bench testing, The Red from the actuator completely overpowers the white screen print. I have...

    Hey everyone. I have 2 OMC Cobra questions. First, I see there are prefab holes in the exhaust bellows at the rear most portion of the bellows, there is a lot of gear oil leaking from there. I'm guessing a blown seal or cracked case. I plan on pulling the drive to find out, but I wanted to...

    I need flywheel help on my Merc 140

    So after research here and finding that the 120's have a pulley and no damper, I looked at my Merc again and it has a damper. This leads me to believe that it is in fact a 140. The Flywheel I have from my 1986 140 will not fit, it is too big (bolt pattern). The motor I have is stamped: 14096613...
