Hello, I had to remove my lower unit to replace a seal last year now my boat will only shift into reverse and not go into forward. Did I mess something up with the shift linkage and will have to take the outdrive off again or would I be able to adjust the cables?
Hello,
I have a 1991 OMC with the 4.3L GM engine and a 4160 Holley carburetor on it. The original owner had a brand new motor put into it as the person who winterizes it for him forgot to winterize so his insurance covered a new engine. Since i purchased the boat i did notice the idle was a...
I have a 1991 OMC 4.3L with a Holley carburetor on it. The number i find is 80315 and it looks almost exactly like a normal 4160. What i am wondering is if the regular 37-119 carb rebuild kit would work for this or do i need to get the marine 18-7237?
Hello,
For some reason my boat is set at around 1300-1400rpm at idle. I am trying to adjust the idle screws on either side and the main idle screw but if i drop it down below 1200 or so it will die. Is there a simple fix for this or anything i can do i am not sure if the carburetor needs a new...
I recently had hit a few rocks on my lower unit and broke some of the blades off of my aluminum prop, with no other damage to the lower unit but a few scrapes on the skeg. On the way back to the landing you could feel a vibration in the boat so we went slow, after arriving it was clear the it...
I have the 1991 4.3l Cobra Spitfire with the coil pack system on it. I recently replaced the starter and all was well until yesterday we pulled the boat to shore took a few minute break, went back out to start it and the engine turned over once then clicks. Figured it to be dead battery, went...
I have the 4.3l OMC Cobra and I know there is a big difference in the starter motors as far as spark arresting coatings on the marine starters. When I look up replacement starters online a lot look like regular automotive starters without the coating to protect from spark. Wondering if I am...
I need to adjust my idle fuel mixture screws on my 1991 Cobra 4.3l HO and in the manual it says to start at 314 Turn Out, wondering if anyone know what this means for initial setting. The reason I am going to adjust this is because twice now when I took my boat out after about 15 minutes of...
When i get my 4.3l HO Cobra up to temp and drive it for about 10 minutes and get it up to about 3000 RPMS the engine or outdrive starts shaking the boat like i am hitting some waves and sounds like its sputtering a bit. I changed coil and spark plugs noticed maybe one of my wires had a little...
I recently purchased an boat with an OMC v6 4.3l with an everstart 24ms starting battery in it. My question basically is if this battery is strong enough to run a radio for a while without it getting too low to crank over a V6 engine? I really don't want to get stuck out on the water with a dead...
Re: OMC Cobra 4.3l Holley carburetor electric choke question
Hi Bondo,
Here is the picture of the 4.3l Cobra HO carburetor's electric choke,
I need to run the Positive wire to a keyed power but i have heard not to run to the alternator, Coil, or starter. Basically what i need to know is...
I have a the OMC Cobra 4.3l (HO I believe) and it has the holley carburetor with electric choke, I was looking over the engine and noticed I have no Positive wire going to the connector, only the negative is hooked up. Is this an issue that will cause the choke to not disengage? Also if it is...
Recently purchased a boat with the OMC Cobra 4.3l Sterndrive, I am a little concerned about this loose wire that looks as if it should and was connected to something at some point. This wire is in between the coil packs and air filter/carburetor also near the alternator. Any help would be...
Re: "Do not pull this plug"
I recently purchased a boat with the OMC Cobra 4.3l and had the same issue, I went to the local marine shop and the technician sold me a small livewell plug and this seems to be working. He said that this is just a drain plug and would not hurt to put a plug in it...
