    Manual jack plate starting height

    That starting point is probably fine. Check to make sure she is pumping water when on plane, but I expect she will be fine. A trick is to close up the top water intake hole and enlarge the bottom one. Just so you are expecting it, as you raise the engine height, the trim loses influence. At...

    Too much wind and rain in my face

    Very cool on that modification. I always thought that a Dual Console offered the wind/rain protection w/o the screens and $$ you have been asked for. You can still fish off the bow of a DC but need to put your butt in a seat to be comfortable. Just my opinion. Now if you want to go out...

    In-Line Fuel Filter Question

    Gee, don't have time to clean tanks and filters? That sounds like crap. They may not want to change filters, but they do have the time to do it. I am not sure what the laws and regulations are about changing filters, but if a gasoline station gets a reputation about bad gas, I would think...

    knocking sound in lower section of engine cowl, above lower unit.

    That "bushing" looks like a bearing to me, although I have not looked it up on the parts list. You might see if it turns, as it appears to be pretty rusty. Perhaps the driveshaft spins and the bearing doesn't?

    Rebuilt Water Pump Pee question

    Mike, when running on the flusher, you will see the water being sucked into the motor. Install the flusher and hose, turn the water on, motor off. Observe the water pouring onto the ground. Start the motor-nearly all the water will be sucked into the motor for at least 30 sec. if that...

    In-Line Fuel Filter Question

    Why would a high volume station give bad fuel, when it pumps 10K gal per shift. They would lose business to the local shmo. Do you have any evidence to back up your claim?

    Run Merc 3.0LX on external fuel tank

    Gee, the fitting looks good. Is there a tube into the fuel tank to suck up the fuel? New tanks have that, used tanks, who knows.

    Gear Oil In My Bilge

    OK, post 5 lists some likely causes.

    Engine dies under a load

    Gee, sounds like the carbs. Put a flusher on the motor and give it a shot of 50::1 down the carb throats. Crank it up, choke closed and see if she runs a bit. If so, the carbs likely need cleaning.

    Gear Oil In My Bilge

    Gear lube in the bilge on a MerCruiser usually comes from a leaking yoke seal on the driveshaft. See if you can detect the gear oil by sticking your finger on the bellows from inside the boat, or pull the outdrive and see if gear oil is in the driveshaft bellows. As for the water, I am not...

    Trim won't go all the way up

    To trailer the outdrive, push the middle and up button at the same time. That is how it was originally designed. The fact that the middle button trims the OD means that either the system is wired as it came from the factory and the trim limit switch is working, or someone has modified it, in...

    In-Line Fuel Filter Question

    High volume gasoline stations have the least water in their tanks. They have thought of raining when filling. Stick with them for clean fresh fuel. Do install a water separator, however.

    pressure test lower end adapter

    The gearcase lube pumps work much better than squeezing the gear lube tubes. The larger gearcases take 25oz of lube, so you often need an extra qt of lube as sometimes the pumps don't like to pump the last of the lube.

    pressure test lower end adapter

    Gee, I pull the hose of the gear lube, screw it into the gearcase and stick a hand pump onto the hose.

    Run Merc 3.0LX on external fuel tank

    You can probably reuse the fuel after filtering it and pouring off any water and water+alcohol, however, you need to at least smell it to determine if it is still good. Bad fuel has a castor oil-sorta smell. That you should use to start campfires, if it still will burn. Worse comes to...

    Run Merc 3.0LX on external fuel tank

    A single water separator should be more than adequate to filter your fuel. A second one will restrict fuel flow and is unnecessary. Your carb should not get gummed up that often. I rebuilt my MerCruiser carb once in the 10+ years I owned it, and I bought it used. Something is amiss, I would...

    Run Merc 3.0LX on external fuel tank

    Mike, I think you should connect the aux tank to your water separator. Although ethanol fuel is not the devil alot think, it still benefits from a good filtering before use. Are you going to clean your carb before you try this test? Carbs usually get gummed up if you leave them full of fuel...

    In-Line Fuel Filter Question

    The gasoline in the carbs will evaporate when in storage. If the filter is above the carb fuel level, it can drain into the carb, as the gasoline evaporates. So when you ran the 4 carbs dry, some of them still had some fuel, plus any that was still in the filter, lines etc, that could drain...

    Mounting cleats on my dock

    Make sure the cleats are solidly attached. Dock boards are normally nailed down. They are not always solidly attached to the joists, and can pull out, especially if the nails rust. Here on the salty bay, I tie the lines to the pilings, as they are much stronger than any cleat on a dock board.

    Run Merc 3.0LX on external fuel tank

    If he has an electric fuel pump the primer bulb is unnecessary, however, if he has a mechanical fuel pump, a primer bulb will prime the pump and perhaps the carb, allowing the motor to start faster. Since this is for a test, vs conventional use, that could be an advantage.
