Checked my resistance, and it came out to 1.0 Ohms. Low, but within tolerance for a Mk2B wired for 12 volts. This is the one I bought: [www.ebay.com]

For the MOSFET resistance , you should use the 4.5V rating, not the 10V rating when possible. For the IRLB8743 that means Vgs=4.5V is 0.0035 ohms typical not 0.0025 for Vgs=10V. But I do agree those...
