Laying Up/Launching; Inhibiting - Volvo Penta D4 Operator's Manual

Laying up/Launching

Before taking the boat out of the water for winter/out-of-season storage have an authorized Volvo Penta work-
shop inspect the engine and other equipment. Have any necessary repairs or service work carried out so that
your boat is in top condition for the new season.
WARNING! If the boat is equipped with Power Trim Assistant the function must be turned off before taking
the boat out of the water. This prevents automatic trimming of the drive/drives if any test runs are performed
while the boat is on land. For instructions on how to turn off the function please refer to the section "Power
Trim Assistant" in the chapter "Operating".
Inhibition should be carried out to ensure that the engine and transmission are not damaged while out of com-
mission during the winter/off-season. It is important this is done properly and than nothing is forgotten. We have
therefore provided a checklist covering the most important points.
WARNING! Read the chapter on Maintenance carefully before starting work. It contains instructions on
how to carry out the most common maintenance and service operations safely and correctly.
