    Velvo penta does on water

    What you can do is very carefully, remove the 5 bolts/nuts that hold the fuel gauge sending unit in place , lift it out and look inside the tank with a bright flashlight, you will see if there is crud in the bottom of the tank. If so it is best to get it professionally cleaned to avoid chronic...

    Velvo penta does on water

    If the carb was full of gunk, I would be surprised if the fuel tank doesn't need to be cleaned out. You should install a cannister style water separating fuel filter and a new anti siphon valve, at a minimum. I thought I saw a small cannister style filter on the starboard side of the engine, did...

    Velvo penta does on water

    OK your engine will run on land with no load on it, but the minute that you put a load on it (even just putting it into gear in the water puts a load on the engine) it dies. This suggests carb/fuel delivery problems. When you rebuilt the carb how did it look inside? Were all the jets blown out...

    E15 and no REC gas

    If you can get E10, you can use that but if you boat is older and never used E gas of any kind, expect it to clean out the gas tank and may clog filters. E10 is all we can get here and after the first year I didn't really have problems with it.

    Dies when key is released.

    I’d also check for power at the ignition switch terminals. B terminal = battery bolts, I terminal = ignition battery bolts when you turn ignition on, S terminal = start gets battery bolts when you turn the key to start. Make sure the I terminal is not losing voltage.

    Broken engine to outdrive - what am I looking at?

    Might have had water in the bellows which caused the ujoint failure. You can find those housings on eBay. You have to check part numbers and get one that matches yours. There are subtle differences from 1986-1993 and then again from 1994-1998. Or if you have a 94-98 then it’s the same as a...

    Tuneup question

    The marine distributor caps I use always have a rubber gasket not used on the automotive version and as noted the plug wires are longer to clear the bulky water cooled exhaust manifold. I like the AC marine spark plugs because they are very corrosion resistant I have never had one rust even in...

    Batteries status after winter storage

    I've been using Deka group 27 dual purpose lead acid batteries for a long time and I usually get about 7 years out of them.

    Batteries status after winter storage

    I charge them when I put the boat away and maybe once or 2x over the winter if there's no snow on the cover. Then before re-commissioning I charge them again.

    Pasty oil coming out the valve covers

    this is the underside of the pre Vortec 4 bbl intake, notice how the water passage is only up at the very front under the thermostat housing, the Vortec intake has a much bigger water passage under there. Maybe more places for water to hide....

    Pasty oil coming out the valve covers

    The OMC Cobra service bulletin came out way before the VP one did, a few years at most after the Vortecs came out. Can't find it, website where it was no longer has it listed. So who knows, it may be a rare occurrence depending on the angle of the engine, etc.

    Gimbal bearing.

    The price difference isn't even that much. We have this boat almost 20 years, bellows has been changed 2x once in 2005 and once in 2016. The OEM ones are only like $60 for the Cobra. I use OEM whenever I can for the bellows, impellers, fuel filters, etc. The price difference is really...

    Gimbal bearing.

    On the Cobra I’ve used the OE bellows & have gotten 10+ years out of them with the drive stored down. That’s about when you start to see small cracks beginning to form in the folds. That’s a sign the rubber is getting stiff and is due for replacement.

    Pasty oil coming out the valve covers

    I wish I could I looked & looked. Buttt…..if you look at the underside of the pre Vortec & Vortec manifolds (cast iron versions not alu) there IS a difference. The water passage seems to extend under the carb mount area on the Vortec whereas it is only right under the thermostat on the pre...

    Pasty oil coming out the valve covers

    On the pre Vortec the intake drained when you drained the block & disconnected the big hose on the front circulating pump.

    Pasty oil coming out the valve covers

    on the newer vortecs that is true, I'm not sure what changed in that water passage to make that plug a necessity.

    Pasty oil coming out the valve covers

    When you removed the plugs, did you probe the block and manifold drains? They can get clogged up with rust flakes and not drain. That block holds approx 2-3 gallons of water all by itself, each manifold can hold about a half gallon depending on the style of exhaust. On my old 4.3 they used a 90*...
