You will be able to choose the engine that best suits the use you want to make of your boat.
Engine check: what you need to know
Check the maintenance of the boat
Check the motor
It is important to be able to test in a chair and in the water. It is recommended to run the engine for about ten minutes and check for fumes. Cooling water should flow evenly and not exceed 30-40 ° C. Black smoke is a sign of poor nutrition. If it is blue, there may be excess oil consumption and if it is white, you may suspect overheating. In all cases, check the tightness of the seals, the hydraulic circuit, the stuffing box… During your sea test, check the revving and, after returning to port, inspect the oil dipstick to verify that it is there are projections of droplets or a possible leak.
The new engine chosen on used boats must be perfectly suited for its weight and dimensions.
Attention to reconditioning
Perfectly reliable circuits
The electrical system must be properly sized with reliable connections. The air supply must be clean as well as the fuel supply. The dimensions of the exhaust should also match the used engine perfectly.
It is strongly recommended to have an oil analysis carried out. The operation costs less than 100 euros and gives a good idea of the condition of the engine.
Check that the coolant has been constantly changed (blue or yellow color). If it is rusty in color, it is a sign of neglect.
The electrical harness must be perfectly clean without oxidation of the contacts.
Inspect the hoses (which should be soft). The linkage must function properly. Look for any corrosion or overheating.
Also check the fuel filter, the condition of the base, the anode, the propeller. Remember to check the fuel filter, the condition of the base, the anode, the propeller. When the engine is started, check the exhaust.
Get help from an expert
Questions to ask before buying a used boat engine.
It is always good to have access to maintenance and overhaul invoices. Ask what items have been changed (filters, oil, belts, turbines…) and what repairs have been made.
When buying a boat, the number of engine hours can be an important criterion if it exceeds 100 hours per year. But the main thing remains the way the engine has been maintained and overhauled. Better an engine which has a lot of hours but which has been overhauled on a regular basis rather than an engine which has few hours but whose wintering has left something to be desired.
To make an effective inspection, get help from an expert.

The right engine for your boat
Which brand to choose?
Instead, look to reputable brands like Yamaha , Suzuki , Honda , Volvo Penta, Mercury or Evinrude. Minn Kota, Torqeedo or Haswing are sure values for electric motors. Whatever your choice, check that there is a maintenance service near the mooring of the boat. A good engine, whether it is an inboard motor, outboard motor, or electric motor, should be able to improve your boating experience. You will choose an engine whose power will be greater, equal, or less than that of the replaced engine. It all depends on the use and what you want.
If you feel that the engine was too powerful for the use you were making of your boat, opt for a weaker model which will be less expensive to purchase and to maintain. Do not mistake a big engine for a small boat. Some famous manufacturers like Yamaha, Mercury, Evinrude, offer models of several hundred horses. The price is high, and horsepower isn’t everything. Do not hesitate to compare the prices of boat engines.
