    Baltimore bridge collapse

    Does that apply to all vessels? Around here there are a lot of "no wake" zones, but they don't apply to commercial vessels. You'll get tagged for violating a "no wake" and causing maybe a 1' wake with a 30ft boat, while you're being passed by a 800-1000 ft ship going at 10kts pushing a...

    Baltimore bridge collapse

    The EVERGIVEN is a much larger ship and was going faster than this one when it was stopped dead by ~75 ft of sand. o_O

    Baltimore bridge collapse

    At 6:03 in that video, you can see two vehicles on the bridge, travelling westbound (right to left). They are right past the bridge support that the ship hit. At about the same time, the ship lurches to port and the lights from the two vehicles disappear, as if they might have been jostled and...

    Lake Saint Clair Peeps

    Before they put that last section or two in, they should arrange somebody like Travis Pastrana or Levi Lavallee to jump the gap!

    I can't be the only one fascinated by this Titan sub ordeal

    Their big mistake was not necessarily the design, it was reusing the sub for multiple dives. The Apollo Command Modules and the Lunar Modules had 100% perfect service records on their flights to the moon, but NONE of them were reused. What do you think their record would have been if they...

    Can the plane take off?

    And it's that statement that makes this a "divide by zero here" problem and ends the test. Do not pass go, do not collect $200.

    Can the plane take off?

    That's a different question/riddle than the OP. This one says "...a giant treadmill that can move in the opposite direction..", whereas the original stated ""The belt conveyor is designed to match the speed of the wheels""

    Newbie - pods are scary?

    Yes, the pods move around and shift gears but that's not a function of the pods, it's a function of the position-holding feature. It would be the same if you have AXIUS with outboards or outdrives. And on docking, it's a function of the skipper rather than the pods. If the skipper is...

    Seacock grease fitting.

    Once they're EMPTY of water, the grease will fill the cavity so that it won't refill with water. Or at least won't fill any significant amount with water. If you're not going to fill them with grease, then you should operate them from one extreme to the other when out of the water, or when...

    Which pink for A/C?

    I'll beg to differ on that one. National pipeline companies don't run Ethanol or Ethanol-based fuels through their pipelines because of all the corrosive effects. There are newer pipelines that are intended for Ethanol but they are pretty rare. I also mostly used air to blow out the...

    Which pink for A/C?

    The pink for potable water systems typically contains alcohol, and you really should avoid using that for engines or mechanical stuff (with metallic parts). That would include your HVAC or A/C systems. Periodic use is probably not going to be a big issue though, so if you've already done it...

    (Circulation) Water Pump Question

    Since you haven't been able to run the boat hard for a bit... how's the bottom looking?

    Maintenance on seacocks.

    I built a little jig one time to help a friend who had a stuck seacock. He was at risk of twisting off the stem using force on the handle it already started distorting the flats so the handle was a little loose. Luckily he had pulled the boat for off-season storage, so we could access from...

    Maintenance on seacocks.

    I could see not using a petroleum-based grease, but maybe using some kind of teflon. Groco says theirs has some kind of anti-microbial in it too.

    Maintenance on seacocks.

    If they're difficult to operate, then you need to resolve that. I would suggest using GROCO's suggestion and adapting a grease fitting there and pumping in some grease to fill the cavity. Then exercise a few times and see if it becomes normal again. Prior to doing that, you could even run...

    Genny raw water pump

    Well, there's certainly a load on the bearing when you have a fan belt attached to the pulley and tensioned properly. There should be a shaft seal between the compartment where the impeller does its job and where the bearings sit. In most modern pumps that's a mechanical seal, similar to the...

    Genny raw water pump

    There are several folks who have done this. You don't need to start the pump before the generator engine. You could just power the pump directly from the output of the generator (alternator - 120VAC) so that it's running any time the engine is. If you can't get the old pump apart, how are...

    Maintenance on seacocks.

    Usually those are used to DRAIN the trapped water in there for winterization. GROCO (IIRC) also suggests (but doesn't require) that they can be filled with a lubricant so draining isn't necessary and it also protects the ball from growth which can make them harder to turn (and I'm sure the...

    Starting Carbureted engines

    First of all, where do you think that fuel in the float bowl is going?? It's NOT going backwards through the mechanical pump and back to the tank!! The float bowls fill from the top, so there is no way for any siphon effect to pull the fuel out of the bowl. If the bowl is empty, then it's...
