not sure how wide your Jon boat is but I would go with a 3.5HP or 5HP outboard no bigger
The right size for an electric outboard motor for a 10 foot fishing boat seems to be 4 - 5 - 6 hp, 8 - 9.9 hp or 15 - 20hp. It simply depends on what kind of fishing boat it is.
The propeller size on an outboard engine, is dependant on the application. The size of the boat, and more particularly the weight it will carry, determines the propeller size.
Depends if it fiberglass or Aluminium. For Fiberglass you would be looking at around 50hp-60hp and and Aluminium would be between 30hp and 40hp.
It depends a lot on the size of the boat. If it say, a 12 foot boat, probably about 7 or 8 knots (about 10 mph). On a bigger boat slower. As was said these small engines are used mainly for dinghies and for fishing. Answer: I have a 8 foot fiberglass dinghy with a 4 Hp outboard. My GPS says 11km/h under full throttle on a calm lake.
Speed is dependant on a number of factors. Most importantly the size, type and weight of the boat that it is on and the number of people on board. A 50 HP outboard will push a small aluminum fishing boat a lot fast than it will a 20 ft fiberglass boat. I have a 50 HP 2 stroke that will push a 16 foot aluminum boat 35 MPH.
It depends of the size of the boat. A guy with a 15 foot skiff with an outboard could be a commercial fishing boat is he is engaged in commercial fishing. On the other end there are very large factory processing ships that would have very large powerful engines.
The weight of the boat, how it is used, and the water quality all affect how big of an electric outboard engine you need for an 80-foot boat. Larger boats typically need high-horsepower (HP) motors to ensure smooth operation; these motors are typically between 50 and 200 horsepower. Instead of being made for large boats like an 80-foot boat, compact electric outboards like the ePropulsion Spirit 1.0 Plus, ePropulsion Spirit 1.0, and Remigo electric outboard are made for smaller boats, dinghies, and tenders. You would probably need several high-output electric outboards (like a Torqeedo Deep Blue or something like that, or a more potent electric inboard system for a yacht this size. Depending on the weight and cruising requirements of the boat, custom-built electric motors of at least 50–100 kW (about 67–134 HP) are a good option if you're searching for an electric propulsion system for an 80-foot yacht or houseboat.
i have a 21ft sunbrid walk around boat with a 175 outboard motor i would like to know what size propeller should i use
30 gal
The 90 hp Johnson outboard is not shipped with a propeller installed. The correct size is determined, and installed, when the engine is rigged on the boat.
5-10 hp gas motor should be more than adequate. An electric motor would alos work well, especially on small lakes or sloughs without significant current.
This can vary depending on the width and weight of your boat. Check with the manufacturer or dealer to see what size or model they recomend.
