Depends on if they are the same size motor. A boat with two motors of the same size are normally set up that way for handling (primarily aid in steering at slower speeds), but it also provides a level of safety for offshore users should one engine stop running they can return on the other. You will also find a lot of fishing boats set up with two motors. One larger horsepower to get the boat from point "A" to point "B" quickly and a second motor of a low horsepower for trolling (moving the boat at a slow speed while fishing).
Inboard motors are usually heavier than outboard motors and can not be lifted up and haled away every time the boat docks. They do not need to be. They require maintenance but no where near as much.
This depends on the size of your boat, but I would suggest getting two motors in case one has a problem while you are in the water.
do you need a boat licence for a 5hp outboard
99% of the outboard motors need 50:1
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.
Self employed marine operators, usually having ads in weekly want ads or yellow page listings under boats/marine operations. If not comfortable in that, then then the dealership, such as mercury is a top brand too inboard/outboard motors. Depends on your boat, and rather it need an inboard/outboard, and if an outboard, then rather it need too be a long or short shafted motor.
There is many type of info available for small boat motors. The Internet is a great source and starting point for this type of info.
To determine the age of a Johnson outboard motor with the ACN 097 370 100, you need to decode the model number or refer to the manufacturer's records. Johnson outboard motors often have a serial number or model year code that indicates when they were manufactured. Generally, Johnson produced outboard motors until the early 2000s, so checking the specific model details will provide the exact age.
Depends on the boat as well. Some boats have different hull designs. So you would need a little more information to answer that question.
The answer is relative. I have a 4 1/2 HP motor on my 12 foot aluminum boat. It gets me where I need to go.
To find a fuel tank for a 1930 Johnson A-50 outboard motor, consider checking online marketplaces like eBay or Craigslist, where vintage marine parts are often sold. Additionally, specialty marine supply stores or forums dedicated to classic outboard motors may have leads on where to source original or compatible tanks. Local boat repair shops or antique marine dealers could also be valuable resources for finding the specific parts you need.
You can pull a skier at around 17ktns so even with a smallish outboard (25hp) on a dinghy its possible.
