Annual inspections on your fuel systems can ensure proper operation in time for the new boating season. Below are some quick tips and walkthroughs surrounding fuel stabilizers and fuel filters, both for inboard and outboard engines.
Fuel stabilizers can help prevent issues caused by bad fuel. Many additives can also increase performance, improve cold starting, and increase fuel efficiency. In very cold climates, using a winter formula can also help prevent fuel from gelling. When applying, make sure to follow the instructions on the additive container.
For diesel engines we recommend Stanadyne Diesel Fuel Additive Performance Formula.
For gas powered engines, we recommend using Yamalube Fuel Stabilizer and Conditioner. In addition, we recommend fueling your boat with ethanol free gasoline. If ethanol cannot be avoided, use an additive to help prevent any problems caused by ethanol gasoline.
