There are several reasons you might want to replace your boat's engine. First, you can do it to enhance the performance of the boat by fitting an engine that generates more power and torque. These two elements will make the boat suitable for specific purposes such as racing or carrying heavy cargo. Secondly, you can also go for a replacement engine following extensive damage to the one that the boat has. Third, used engines also come in handy when you decide to flip an antique boat and bring it to life after lying unused for a while. If you need to take on any of the tasks discussed here, use the following guide to make the right decisions:
Examine the Engine for Rust
Rust is a common harmful element known to attack boat engines. They are susceptible considering the long hours that the boat spends in deep water. Gladly, boat manufacturers are aware of this risk and take preventive measures to protect the boat's engine. For instance, they use galvanised metals capable of standing up to rust. Therefore, rust around the engine points to an underlying problem. In most cases, it shows that the boat has endured extensive periods of submersion. You will need an overhaul of the engine housing and other components, which translates to more costs after the purchase. Fortunately, many used engines will not have this issue.
Check the Condition of the Oil
The condition of the oil is often a pointer to the well-being of the boat's engine. It also shows the quality of care that has been accorded to the engine over its useful life. Flush out the dipstick and examine the oil carefully. It should be free of debris and metal deposits, which are often an indication of bigger lubrication problems. Additionally, look out for a milky appearance on the oil as it shows that water infiltrated the oil chambers. Such symptoms may point to further problems such as worn gaskets, and they need replacing before fitting the engine. In short, make sure that the oil has a solid brownish look that shows a healthy engine.
Check the Electrical Connections
The electrical connections are essential for linking your boat's engine to the battery so that it can power up. Your most important element here is the spark plugs. They should be dry and free of corrosion. Look out for signs of hardening, and if there are none, then the engine is in good condition. Spark plugs are sensitive and sit deep in the engine, making them a good area for assessing the well-being of your marine engine.
