ENGINE AND HANDLING

Engine Highlights
Interlude is equipped with a Yanmar 45hp 4-cylinder diesel with sail drive that will provide many hours of cruising
pleasure. The saildrive helps eliminate shaft vibration, noise, and alignment problems. Under engine power, you'll find
Interlude to be quiet, balanced, maneuverable, and powerful.

OPERATING TIP: Maximum RPM is 3000. Cruising RPM is 2250-2500. Idle is around 900 RPM. It's OK and in fact
preferred to vary engine speed as you cruise. Please try not to exceed the cruising RPM range.
Inspecting the Engine
Engine access is provided by lifting the companionway stairs, which operate on hydraulic lifts. There are no latches, just
lift it up, push it down. Side access is provided via hatches in the aft cabins.
We recommend performing the following inspections each morning before getting underway:
• Lift the companionway steps to access the engine compartment. Look around and below the engine for any
signs of oil or other fluid leaks.
Check the coolant level. Anywhere between the two lines (high and low) on the overflow reservoir is where you

want to be.
Visually inspect the raw water strainer for debris. Don't open it unless you need to remove debris. In case of an
•
engine overheat alarm, check for eelgrass clogging the strainer. Unscrew the top of the strainer, clean out any
debris, then replace it. CARE SHOULD BE TAKEN WHEN REMOVING AND RE-INSTALLING THE LID – the black O-
ring located around the strainer must be in place and not kinked or bent. If it's not installed properly a leak may
result that could cause the engine to overheat.
• Check belt tightness by deflecting the belt inward with your fingers; it should not depress more than an inch.
Our maintenance pro checks the oil level before each charter so you do not need to do this yourself for week-long
charters. For longer charters (e.g., 2-weeks), we recommend you check the oil level once a week. The dipstick is on the
starboard side of the engine and can be accessed from the starboard cabin (look down and to your left). If you need to
