    Mercruiser hard starting when cold

    I have a 1990 mercruiser 7.4 454. She starts right up if she's warm but it takes 10-20 times to start when she's cold. Once I get it started and let it run a couple of minutes and shut it off, it starts right back up. Do I need a new or rebuilt carb? Is there an adjustment I can make? I just did...

    Mercruiser 454 oil pressure and water temp

    Can someone tell me what my oil pressure and water temp should be at for a 1990 mercruiser 454? My temp gauge for the most part doesn't move off of the lowest spot on the gauge while underway (about 100-120). It will rise a little bit when im in neutral. The oil gauge is reading anywhere between...

    Bravo steering play

    Ok, so I noticed all season that I had what seemed to be loose or sloppy steering. The other day I had the boat on the beach with the drive lifted up and I noticed the drive swinging back and forth about 3-4 inches or so while the steering wheel wasn't moving. I just had a brand new bravo 3...

    Gauges Helppppppp!

    Hey guys, I have a 1990 Cobalt Condure. Im trying to replace the gauges. The problem I have is the existing gauges are an odd size. All the 2 inch holes are a little smaller then the regular 2 inch aftermarket gauges and the 3 inch are closer to 4 inches. Do they make new gauges in these sizes...

    454 Running Hot???

    I have a 1990 Mercruiser 454 Bravo 3. I got it last year. It has been running great all summer. Just this week I had an alarm go off in the dash. I noticed that the temp gauge was much higher than usual. I let it cool off before restarting it and it dropped back down again. It has been doing the...

    Exhaust Shutter Question

    I had that rattling from exhaust shutters that we all know so well. Today i got in there and found the shutters to be in tact and fully operational. The rattling noise seems to be coming from the small metal rod that holds the shutters in place. The rod is smaller in diameter than the hole they...

    Hesitation at WOT???

    1990 Mercruiser 454 Mag 7.4L V8. The engine runs smooth and quiet all the way up to WOT. Once I open it up she hesitates. Rpms up and down and causes the boat to jerk until I back off a little bit, then shes fine again. I just changed the Fuel filter and the filter in the carb. I also did an oil...

    Digital Fuel Gauge

    Can anyone recommend a decent digital fuel gauge that is fairly accurate. I have an older boat (1990) so it doesn't have that NMEA stuff or whatever it is. I have a spot open on my dash where an old round depth finder was and I thought a good fuel gauge would be a good idea. That regular fuel...

    Loose belt question

He came with a big bar for leverage and tightened it again. Its been about 2 weeks and its loose again and squeeking. Why does...
