How to Prepare a Portable Generator for a Boat?

Portable generators have been a very important part of many homes and businesses, but they can also be used for boats.

This will allow you to use the power of your boat without having to rely on shore power or running out of fuel.

Let’s discuss how to prepare your portable boat generator. Follow these for safe operations and best fishing trips, follow these steps:

  1. Clean and inspect the generator.
  2. Connect the battery and connect the power cord.
  3. Make sure the oil level is correct.
  4. Add gasoline
  5. Plug-in electric starter
  6. Pull rope
  7. Verify spark plug
  8. Turn on engine
  9. Add one or two tablespoons of oil to the engine.
  10. Check the oil level.
  11. Stop the engine
  12. Unplug electric starter
  13. Turn off the fuel valve
  14. Disconnect battery
  15. Move generator

1 – Clean and inspect the generator: The first thing that you need to do is clean and inspect your generator for any problems.

Ensure that the plug is clean and that no oil or gas is spilled anywhere.

2 – Connect the battery and connect the power cord: Once you have done this, connect the battery and plug in the power cord.

Make sure that the outlets are ready to use and that nothing is blocking them.

3 – Make sure the oil level is correct: After doing this, make sure that the generator has the right amount of oil in it.

You can do this by following the instructions in your manual.

4 – Add gasoline: Once you have completed these steps, add gasoline to the generator.

You may need to use a funnel if there is not an easy way for it to get into the generator.

5 – Plug-in electric starter: After filling up the tank with gas, plug in the electric starter to the generator.

6 – Pull rope: Pull the cord on top of your generator. Make sure that you do this slowly and wait a few seconds each time before pulling it out.

7 – Verify spark plug: Once you have done this, look for a small spark plug under the cover. If the engine starts, you should see a small blue spark under here.

8 – Turn on the engine: Once you have verified that this is working properly, turn on your generator and allow it to warm up for about five minutes.

9 – Add one or two tablespoons of oil to the engine.: After waiting for 5 minutes, add 1-2 tablespoons of oil to the generator.

Turn off the engine and wait for 30 seconds before restarting it.

You should see a small pool of oil in the bottom of your generator if you use one tablespoon, but if you choose to use two tablespoons, you might not notice this happen.

10 – Check oil level: Once this is done, turn off the generator and wait 30 seconds. Look at the oil level in your generator to make sure you have enough.

11 – Stop the engine: After doing this, turn off your engine completely.

12- Unplug the electric starter: Once you are done with this, unplug your electric cord from the back of the generator.

You can either do this by pulling it out or unplugging the cord itself.

13- Turn off the fuel valve: Now, make sure that your gas is turned off, and nothing is open at all except for the choke (if there is one).

If you have an electric generator, then just turn it off completely.

14- Disconnect battery: Once you have done this, disconnect your battery from the terminal.

15- Move the generator to where it will be used: After doing all of these steps, find a good spot for your generator and place it on a flat surface.

You can do this in a garage or outside if there is a good place to put it.

Ensure that nothing is blocking the generator and that it is not in the way of other objects.

Safety Measure while using a boat generator

The starting and running components of a gas-powered boat generator are the same as those found in any gasoline engine.

Refer to your owner’s manual for instructions on how to check and change the oil, and install spark plugs and hydraulic belts.

Then follow these safety tips:

  • Make sure that no combustible materials — such as rags, gasoline, or paint thinner — are in the area.
  • Always disconnect the shore power cord before starting the engine.
  • Keep an approved fire extinguisher, Class B-rated gas can, and extra fuel on hand when fueling.
  • Position your generator so that exhaust fumes vent away from living spaces. Note: On boats with enclosed cabins, it is often necessary to install an after-market venting system.
  • If the generator’s installation requires running wires under the floor or through a wall, make sure that the wiring is installed correctly and in compliance with local electrical codes.
  • Do not store gasoline containers on your boat while you are sleeping there.
  • Never run a generator on board your boat while you are sleeping. Please note: Allowing the exhaust to vent into an enclosed cabin violates EPA emission standards and can be hazardous; some states prohibit this practice. If you choose to use a generator in such a way, make sure there is adequate ventilation or that the unit has an approved carbon monoxide monitor.
  • Install a carbon monoxide monitor, and never use a generator in an enclosed area without adequate ventilation. In addition to using generators carefully on board your boat, be safe everywhere else: Never operate gasoline-powered equipment or tools near an open flame or while smoking.

Final Verdict

FAQs: Best Portable Generators for Boat

What is the best place to install the portable generator on a boat?

The best place to install a generator in the boat is in the engine compartment because it’s protected from rain and spray.

Installing a permanent generator on your boat can be dangerous and unhealthy.

You should keep it in dry locking when not running, but you may want to install one if there’s no other place for storage or protection from weather conditions like spray!

Make sure that the location will avoid filling up with smoke – stay away from decks near cabins where people spend the most time during their day (especially kids), and windowsills inside living spaces open into exterior areas accessible at sea, like swim platforms.

These locations could become hazardous quite quickly, so make certain first before committing yourself by installing them permanently.

Do I need to ground a generator on a boat?

The short answer is no, but with some caveats. A properly designed marine generator should have its own isolated neutral so it can be used close to the metal without creating any safety issues.

That being said, grounding the generator won’t hurt anything; you just don’t have to do it.
