    Glastron gx 185 early 2000s

    I'm thinking of upgrading from the old 1990 Sunbird. I've been looking at 2001 to 2004 Glastron gx 185's. I've had the Sunbird for 4 years now. It's a great little boat when everything is good. But it seems like each year, something major breaks on it. 2014 the shifting cable was wonky and had...

    OMC Cobra 4.3 model number question.

    I need to replace the outdrive on my 1990 OMC cobra 4.3. The model number is 986032. I found an outdrive off of a 4.3 the model number on that one is 984541. From what I found out by researching it appears to be from a 1987 model. Can I use the one that I found? Are the gear ratios the same for...

    OMC Cobra Outdrive question

    I have a 4.3 v6 Cobra. The outdrive is shot ( someone did a patch job on the case years before I got it and the patch gave it up on the lake one day and well, now the whole thing is toast. BTW, they put a ton of paint on it and neither me or the previous owner had any idea it was there.)...

    Boat has been running great! Then last night took it out for a cruise and on the way to the dock, throttled down and the motor cut out. Docked the boat and tried to start it. Engine cranked and didn't start. Moved the throttle to give a little gas, turned the key again, this time, nothing at...

    Sunbird Gas Tank Check Valve

    Last year we noticed there was gas weeping through a minute crack between the bilge and the fuel tank compartment. There were no problems with any leaks on hoses or pumps in the engine bay. The only way to get to the fuel tank was the cut a hole in the deck. As it was the end of the season, we...

    Marine Supply Store with best selection of Fuel Tanks- Re: 1990 Sunbird 4.3 OMC

    I need to replace the fuel tank on our 1990 Sunbird Corsair. The place where the tank fits is very specific for shape and size. The well it sits into is molded in fiberglass and it really limits the size and shape of replacement tank choices. I've looked at a number of marine supply stores, and...

    OMC Exhaust Flapper/Seal Question

    I need to order two new flappers. I have been looking around and are there different sized flappers for the 4.3 HO? Or are they the same size as the regular 4.3?

    Cooling System Questions

    I have a 1990 Sunbird with an OMC Cobra 4.3 HO. Changed the alternator and fired up the boat with the muffs on it and everything seemed fine. Temp was normal. Got it out on the lake the other day and it overheated very quickly. I probably shouldn't have taken it out on a such a busy day, there...

    Prestolite vs Mando Alternator OMC Cobra

    Other than the terminal labels ( for example instead of G for ground, Mando has E for earth), what is the difference between these two alternators? Is there anything internally that is different? Output, ect? I know the Mando alt I have is a 55 amp but from what I had researched the older...

    Alternator hookup on Sunbird OMC

    I have a 1990 Sunbird with a 4.3 OMC and I bought a new alternator. The new alternator is a little different and it's very unclear what goes to what. We know where the positive goes, but the other 3 leads are confusing. I'm not the mechanic but my brother and bf are working on it and they are...

    Quicksilver Black Diamond prop results

    Got the boat out on the lake this weekend after installing the Quicksilver Black Diamond prop. Went with the same specs as the old prop 14.25 x 21. Well it feels like a 19. The boat snaps up on plane twice as fast as it did with the old prop. It's revving higher. It used to be about 4600 wot...

    Torque prop nut?

    I've not replaced a prop myself but two of my friends have. One tells me that the nut does not need to be torqued. The other friend says to torque it. Does it need torqued after I install the new prop and if so, how do I find the setting for the torque wrench?

    Michigan Wheel Vortex or Quicksilver or Hustler Prop?

    Ordering a new prop for the little Sunbird I have, 18 ft, 4.3 V6, Cobra outdrive. I hit rock yesterday and its time for a new prop. 14 1/4 dia and 21 pitch. I want to keep a good cruising speed, so I'm staying with the 21 pitch. I might get a 19 later if I start pulling tubes or wakeboards a...

    The little Sunbird is up and running and I even bought a decent truck to tow it with. Putting it in the water this weekend. Got a question, can a newer, more modern out drive be attached to that Cobra 4.6 motor?

    The Little Sunbird Lives again!

    Ok My friend came over and he removed the outdrive and took a good look inside. Everything looked fine. Nothing jammed and everything moved the way it should. He put it back together. He did see that the Transom Bracket cable seemed a little out of adjustment and the linkage looked a little...

    Bad day on the lake

    Ok so I take the Sunbird Corsair out for the first time without my friend who I bought it from. Drove the boat away from the boat ramp, drove down the cove to our dock. Had to wait for my bf to get there. He had to move a sailboat to make room for me to tie up. So I shift the boat into neutral...

    Advice Needed on buying a Sunbird Corsair

    I have the opportunity to buy a 1990 Sunbird Corsair 18 ft with a V6. A good friend of mine bought it earlier this year for $1900. It had a cracked block and cracked manifolds. He picked up another motor, and rebuilt it, stroking it out. The rebuilt motor runs like a top and fires up with the...
