If your engine mounts are more than five or six years old, or have been contaminated with seawater, engine oil or coolant, change them.

Despite the engine’s best efforts to twist itself out of the engine compartment, the process of acceleration is largely uneventful thanks to the system of motor mounts holding the power plant firmly in place.
