With only 1/2" of shaft exposed, galvanic currents will be so small no extra protection is needed. There are threaded cones to replace a prop nut,...
A submerged valve doesn't seem like a good idea to me because it only takes a tiny piece of debris to prevent the valve from closing fully. In...
The galvanized bolts will protect steel surfaces they are in contact with until the zinc layer has gone. I estimate 2-4 weeks in seawater, up to...
1) is not a good idea. During starting both batteries supply 1/2 of the 200 Amps your starter needs. 15amp rated wires will heat up very quickly....
Using the same drive, your VW engine will also need 3200 rpm for 20 mph. Maybe a little less because the VW engine is lighter. At that speed the...
Adding a keel certainly improves low speed turning. The penalty of course is reduced turning capabilities at high speed.
One way to do this is putting a semiconductor switch (Mosfet) in the negative lead of each battery. They are cheap and normally do not spark. But...
The thermal sensor is useful to determine the fully charged state of a battery because it is temperature dependent. It cannot prevent thermal...
The radio transmitter employs one or more quartz crystals to generate stable carrier frequencies. In FM transmitters the resonance frequency is...
What at first glance seems a brilliant plan may be a waste of time and materials. The resin hardens with an exothermic reaction that changes the...
The same sheet says the stall torque is 75 ft. lb, which is slightly more than 100 Nm. That seems like a reasonable value for a light weight...
If the gas is wicking up the threads, remove the screws and apply some Loctite 577 (pipe sealant).
First of all make absolutely sure the Yamaha can power your A/C as most small generators can't handle the inrush current. Second, it produces 60...
MS5837-30BA from Digikey is a tiny gel filled sensor that can be installed in a 3 mm hole, sealed with an O-ring. It has an I2C interface, so a...
If the return line is just for leakage of the injectors, one flow sensor in the supply line is enough for your calculations. If your engine is a...
