Figure 3.1 – Pre-Start Check Points
1. Check the boat hull and/or garboard drain plug. Make sure
they are installed and secure.
2. Carefully inspect engine compartment for signs of fluid
leakage and proper ventilation. Unlike autos, marine engine
compartments require positive ventilation and air re-circulation
to ensure that flammable and explosive vapors are safely
dispersed in an environmentally sound manner.
