Which motor for which boat

Match the motor to your Rover.

8 ft Battle Cat and Battle Boat: up to 6 hp

2 people and 600 lb. Within the rating: Yamaha 2.5, 4 and 6 HP (the 6 is right at the rating), and the Torqeedo Travel XS, Travel S and Travel XP. The Travel XS is the natural electric match.

10 ft Battle Cat and Battle Boat: up to 10 hp

4 people and 1,000 lb. Within the rating: Yamaha 2.5, 4 and 6 HP, the 9.9 HP as a configuration to evaluate, and all three Torqeedo Travel motors. With a full crew, more power feels less leisurely.

12 ft Battle Cat and Battle Boat: up to 20 hp

4 people and 1,200 lb. Every motor we carry sits within the rating. The Yamaha 9.9 HP is an all-around match; the 15 HP is the most power we carry. The smaller motors run it at easy speeds with a light crew.

Every Rover takes a short shaft

All six Rover boats list a 15 in transom, so they take a short-shaft motor: 15 in on a Yamaha, 62.5 cm on a Torqeedo. None of these is an automatic fit approval: check your exact boat, motor weight, mounting and total load.

Keep the boat you love, or build something new

Three checks before you repower.

01. Read the boat rating

Check the horsepower and motor-weight limits on your actual boat and model year. Electric motors still count against the rating, and a battery adds weight on the transom.

02. Match the shaft

Use the shaft length your transom calls for. Rover Marine boats have a 15 in transom and take a short shaft. Do not pick a longer shaft just to get electric start or power tilt.

03. Plan the complete rig

Confirm mounting, steering clearance, propeller, fuel or charging, and any starting-battery needs. Count passengers, motor, fuel or battery and gear in the boat's load.

Gas motor questions.

Why choose a gas outboard over electric?

Gas motors give you the most range and the fastest refuel: add fuel and go. They suit bigger water, heavier loads and long days away from the dock.

What size Yamaha do I need?

Start with the boat's rating: 6 hp on the 8 ft Rovers, 10 hp on the 10 ft and 20 hp on the 12 ft. The 2.5, 4 and 6 HP suit the 8 ft boats and light crews; the 9.9 and 15 HP suit the 12 ft boats.

Are the fuel tank and rigging included?

The 2.5, 4 and 6 HP have a built-in tank. Ask us to confirm the package contents for your configuration, including the propeller, fuel tank and hose, and starting-battery needs.

Do gas outboards need winterizing?

Yes. Basic seasonal care includes stabilizing the fuel, fogging the engine and storing it properly. Your Yamaha owner's manual covers the full checklist.

Can I use a gas motor on my lake?

Many lakes allow gas motors, but some restrict them. Check your local regulations before you go; electric motors are often still allowed where gas is restricted.

Who handles motor warranty and service?

The motor maker. Yamaha, Torqeedo and ePropulsion handle warranty claims and service directly, and we are happy to point you to the right contact.

Can I return a motor?

Motor sales are final. A 7% fee applies if an order paid with a financing plan is cancelled. Not sure which motor fits? Call 888-978-1503 before you order. Returns and refunds
