Top Features
  • Yamaha generators have the longest emission engine durability ratings issued by the Environmental Protection Agency and the California Air Resources Board.
  • The EF1000iS weighs in at 27.9 pounds, making it extremely portable.
  • Noise Block is Yamaha’s acoustically engineered sound reduction system which helps make the EF1000iS among the quietest portable generator in its class. (47 dBA to 57 dBA – ¼ rated to rated load)
  • Gasoline petcock lets you shut off the gas to run the carb dry for storage and helps prevent stale gas problems.
  • The EF1000iS features Smart Throttle, a load sensing rpm control that allows greater fuel efficiency and noise reduction by automatically adjusting engine speed to match the load. It will run up to 12 hours at ¼ rated load on a tank of gas.
  • The Yamaha EF1000iS inverter generator supplies clean, high quality power. The EF1000iS – with its inverter system – features Pulse Width Modulation (PWM) so voltage stability is within ± 1%, and frequency stability is ± 0.1 HZ. Its pure sine wave is as clean as or cleaner than public utilities power.
  • The Auto Warm-up feature automatically increases engine speed for 4~6 minutes to ensure smooth power delivery during cold start ups.
  • Yamaha’s Oil Watch Warning System helps prevent engine damage from low oil and provides added peace of mind.

Remember to bring your ID with you.

Either in the dealership when you're picking up your unit or at home! We can send most of the contracts to you via email for e-signing, if you prefer to complete those ahead of pick-up.

Once we’ve confirmed your pick-up time, we will send you a list of what you need directly to your email, so don’t worry about forgetting a thing.

We will reach out to you directly and schedule your pick-up via your preferred method of communication–phone, text, or email.

Approvals usually happen in minutes. Almost always the same-day during our regular business hours:
9-6 M-F, 9-3 Sat, Closed Sun

Fill out your credit application online, and we’ll contact with your options upon approval. You can then e-sign all of your contracts from the comfort of your home, or come into the dealership and sign before pick-up.

Before you complete your purchase, we can make sure everything you need is added as far as accessories for the unit or gear for you. We also offer 10% off any non-sale gear and accessories on your day of purchase, which can be redeemed in-store or online via a special code we will send you.

If you can’t find exactly what you’re looking for, don’t worry–we can help you add those items to your purchase, even if they need to be special ordered!

Pre-orders

These units are rare or hard-to-find. We provide a manufacturer estimated delivery window when you Request Availability.

This means we are looking for your unit and/or waiting for the next ordering opportunity with the manufacturer of your requested unit.

Don't worry--we are just as anxious to give you this unit as you are to receive it, and we will keep you in the loop of any status changes!

Yes! For the majority of units, your deposit is refundable for any reason you may have! Most units require $100 deposits to hold, while watercraft require a $500 deposit.

However, limited edition or rare units that we do not normally keep in stock require a non-refundable $1000 deposit.

Any way you prefer: phone, text, email, drums and smoke signals...

We will do our best to fill your order in the most reasonable time possible, and should there be any delay, we will get in contact with you for all of the available options.

We require that the unit is picked up within 48 hours of being notified, but let us know your schedule and we will do our best to accommodate!

If a unit is not picked up within 24 hours of notification and we have not heard back from you during that time, your deposit will be forfeited and the unit made available to the next person in line.

Yes! We do our best to work with our customers' needs.

Yes! Your deposit is put towards the first available unit of your choice--even if that choice changes!

Nobody likes to hear this, but occasionally it happens. Should this happen to your unit, we will be in prompt contact with all of the available options, such as moving your deposit to the next available unit of your selected type or an entirely different unit that still suits your needs. 

In some cases, manufacturers will switch over to a new year model to complete an order. If your deposit for a unit falls into this category, your deposit is tagged to a newer model. If prices or colors don't suit you, your deposit is fully refendable.
