    Only 4400 rpms on V6 4.3 2005 19P 3blades

    I have a 15.5x15 on mine (1.62:1 drive ratio) and it will pull 5,000 or a bit more even WOT. While this definitely lowers top speed the more important result is that it reduces the strain in the engine every time it has to pull the boat up on plane. I’m willing to sacrifice top speed for better...

    OMC Cobra Information

    That's a Chevrolet 5.0 with a Holley 2bbl carb, nothing out of the ordinary about them, but if you anticipate freezing temps you must manually drain all the water out of the engine and exhaust system. There are two drains on the engine block, one on each side, lower midsection area, and each...

    Help find part number of OMC engine

    Ok what part(s) do you need, many of them are the same for all years of Cobra production but some are not. OMC identified their products by model # which was for the whole power package (engine transom mount and outdrive) this model # is what you use to buy parts. In addition the drive has a...

    Fluid Changes for Winterizing, Do I Need to?

    Very interesing here we have the lemon law, they get 4 tries to fix a problem but there is some interpretation, in that the defect must impair function in some way, so things like minor blemishes or squeaks and rattles don't qualify but water leaks that cause rust, operational problems that...

    Help plz, 2002 3.0 mercruiser winterizing question

    If you filled the exhaust manifold with AF that’s normal there are idle relief openings on the bottom of the transom mount where water exits when the engine is running. Now if it came out the bilge drain plug hole that might just be spillage.

    Fluid Changes for Winterizing, Do I Need to?

    I don’t think a once a year oil change should stress anyone out; keep in mind older carbed engines run cool and rich therefore fuel dilution of the oil is a real issue and this has also been a problem on modern 4 stroke outboards. Despite up to date fuel and ignition systems they run very cool...

    Antifreeze circulation through engine

    Ah just saw your post, if that’s in the hose leading to the manifold from the thermostat housing I’d remove the housing and see what’s going on in there. If the intake looks really rotted right under the thermostat you may need to replace it. There is a water passage at the front of the intake...

    Antifreeze circulation through engine

    Is that from the engine block or the exhaust manifold? Either way that’s a LOT of rust flakes….I’ve been boating in salt water close to 20 years with the same boat and engine and never seen that many rust flakes when I winterized it. Salt water use? If from the block I’d remove the thermostat...

    Antifreeze circulation through engine

    PS I tried that way the first year I winterized and then thought to check the strength of the AF in the block, drained some into a paper cup and it looked like rusty water, did not seen to have any AF in it....so if you do this method it would be interesting to take a sample from one of the...

    Winterizing a 2004 3.0 glm-b

    That is correct, for freeze protection all you have to do is properly drain. The AF is only for added corrosion protection and probably unecessary in the fresh water Great Lakes. Here in salty LI Sound, we do it, lol! We also have to replace exhaust systems every 7 or seasons, which you probably...

    4.3 GXI hydraulic steering leak.

    that would be a nice easy solution. In my case it was the control valve leaking where it mates up to the hydraulic cylinder. Installed:

    Second Happiest Day . . .

    LI Sound when it gets windy or the wind is against the tides can get 'interesting', I only have ventured there on very calm days early in the day before the wind kicks up. Then there's the rest of the trip, Block Island Sound with the New London Ferry traffic, the Vineyard, etc. To me it looks...

    Second Happiest Day . . .

    Even for my friend, with a boat about the same size as ours, his marina/maintenance costs were close to $10K a year whereas I was paying $400 to rent a mooring and $500 to get bottom paint done, the rest I did myself. Even if I add the water taxi service from the boatyard to the mooring to the...

    4.3 GXI hydraulic steering leak.

    While V/P says you cannot rebuild the ram, which is about $900 new, there is a company in Florida who can rebuild them for about half that. Getting at that thing is not easy, I just replaced the older style one used by OMC and Merc on my old '88 Cobra. Its behind the engine up against the...

    Second Happiest Day . . .

    And those are Long Island prices! I recall some years back a friend asked us how much it cost to keep our boat on the mooring; he was in a very nice local marina and had them do everything whereas I like most people on this board do everything myself except for bottom paint. I have always kept...
