    Water in gear oil... (Not a great day)

    It's just the way it is with older outdrives. I had to change the water pump shaft seal on my Cobra for the same reason, was getting a bit of milky gear oil after pulling the plug, the rest of it looked OK. On these the shaft wears a groove in the shaft so the original seal doesn't last as long...

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    You’re actually better off with the mechanical pump. Less to go wrong. Glad it was a simple problem!

    How to tighten up rack/pinion slack in steering

    Might as well replace both at this point

    VP 5.7 TBI bogging down

    You checked the fuel pick up screen but did you also check the anti-siphon valve? Also, a good way to rule out the engine fuel system is to run the boat on a separate outboard tank with fresh gas, if it runs good then, you know it's not your EFI system or ignition system, it's something in the...

    1999 4.3L...

    Glad to hear that! Think about that 2 piece conversion we discussed. Long term it’s the way to go.

    1998 Mercruiser 4.3 Tick/Knock

    Agreed & first thing to check with the stethoscope is the exhaust flappers, they can make noises that sound like engine problems. You can also try temporarily disconnecting each belt to see if it’s a water pump or P/S pump….

    How to run twin 5.0s from portable outboard tanks

    2 six gallon tanks should be fine, I was able to run my 4.3 at WOT with that West Marine tank in my pic with no problems. Are you getting the OE tank replaced? If so check out Rob at Raybo Marine on Montauk Highway in Lindenhurst. Does great work.

    How to run twin 5.0s from portable outboard tanks

    I thought about this as well when I was doing my testing last summer. I figured even running at 3500 rpm on plane I’d be using approx 5-7 gallons per hr. The outboard tank I had was 6 gallons so I brought another 2.5 gallon gas can so I could do enough testing to prove to myself that my problem...

    Engine backfiring through throttle body when trying to accelerate

    They can be reused if they're in good shape, you can use a fuel resistant sealer like Gasolia on it and the attaching bolts/screws. In the past in a pinch, I've used Permatex Aviation as well. Not sure if I'd add an additional filter because it might add too much restriction.

    4.3L Mercruiser overheating at idle

    Are you sure the outdrive water intakes aren't clogged?

    Engine backfiring through throttle body when trying to accelerate

    That's what I always thought, till one year when it didn't. Maybe a good idea is to take off the fuel filter in the spring and test for water in the fuel but with E10 you will not see it till it's phase separated. So using one of the available test kits might be a good idea.

    Engine backfiring through throttle body when trying to accelerate

    Agreed, I don't know if your engine has a knock sensor or not but even so sometimes you just gotta just bite the bullet and get it done. And even if it had a knock sensor, you'd have terrible performance due to the timing having to be so far retarded. We had a '98 Subaru Outback that had a knock...

    2004 Volvo Penta 5.0GL-E with SX-M outdrive leaking through exhaust into bilge

    Starter itself, unless you have easy access to it when the engine is installed check oil pan for rust, dipstick tube fitting for leaks P/S oil cooler and lines that are on the back of the engine bilge pump if under the engine as some are how's your oil filter access? If not good, maybe add a...

    Engine backfiring through throttle body when trying to accelerate

    I think if you can do that it would be worth a shot, but here's the issue, if you have water in the fuel and you were using E10 fuel, it could be phase separation in which case you'd be left with low octane fuel that might cause detonation. Also, if you want to get all the way down to the very...
