A 1972 65 hp Evinrude outboard motor typically weighs around 140 to 150 pounds (63 to 68 kg). The exact weight can vary slightly depending on specific model features and configurations. Always check the manufacturer's specifications for the most accurate information.

A powerboat that has run aground during periods of restricted visibility is required to sound a signal of one long blast followed by two short blasts at intervals of not more than two minutes. This signal alerts other vessels to its situation and indicates that it is not making way. Additionally, the vessel should display appropriate day shapes, such as a ball shape, to indicate that it is aground.

The speed of a 35 hp motor depends on various factors, including its design, type (AC or DC), and the load it is driving. Generally, the speed is measured in RPM (revolutions per minute), and for most standard AC motors, it typically operates at either 1,750 RPM or 3,450 RPM, depending on the number of poles. However, to determine actual speed in terms of linear motion, you would need to consider the motor's output shaft, any gear reductions, and the application it is used for.

The Evinrude model E10RC1D with the serial number E0001742 was manufactured in 2000. Evinrude uses a specific coding system where the first letter in the serial number indicates the year of production. In this case, the "E" in the serial number corresponds to the year 2000.

To determine the year of a Mercury outboard motor, you can reference the serial number. The serial number 2293632 indicates that this 9.8 hp twin outboard motor was manufactured in 1977. Mercury typically assigns serial numbers sequentially, allowing for year identification based on the number.
