Maintenance Schedule—Inboard Models
Routine Maintenance
NOTE: Only perform maintenance that applies to your particular power package.
Task Interval Maintenance to Be Performed
Each day start
• Check the engine oil level. You can extend this interval based on experience
with the product.
• Check the transmission fluid level.
Each day end
• If operating in saltwater, brackish water, or polluted water, flush the seawater
section of the cooling system after each use.
Weekly
• Check the water inlets for debris or marine growth.
• Check and clean the seawater strainer, if equipped.
• Check the coolant level.
• Check the transmission fluid.
Every two months or 50
hours
• If operating in saltwater, brackish water, or polluted water, apply Corrosion
Guard to the power package.
• Check the battery connections and the fluid level.
• Ensure that the gauges and the wiring connections are secure. Clean the
gauges. If operating in saltwater, reduce this interval to every 25 hours or 30
days, whichever occurs first.
Scheduled Maintenance
NOTE: Only perform maintenance that applies to your particular power package.
Task Interval Maintenance to Be Performed
After the initial 20‑hour
break‑in period
Change the engine oil and filter.
• Change the engine oil and filter.
• Change the transmission fluid and filter. ZF Marine requires changing the
transmission fluid and filter maintain warranty.
Every 100 hours or
annually
(whichever occurs first)
• Touch up the paint on the power package.
• Change the engine oil and filter.
• Change the transmission fluid (ZF Transmission Models).
• Replace the water‑separating fuel filter element.
• Clean the flame arrestor, IAC muffler (MPI engines), and the crankcase
ventilation hoses. Inspect the PCV valve, if equipped. On MerCruiser V6
models, the PCV valve is a non‑serviceable, internal component of the valve
cover assembly.
• Inspect the condition and the tension of the belts.
• Check the coolant level and antifreeze concentration for adequate freeze
protection. Correct if necessary. Refer to the Specifications section.
Every 300 hours or 3
years
(whichever occurs first)
• Check the engine mounts for tightness and tighten to specifications if
necessary.
• Check the electrical system for loose, damaged, or corroded fasteners.
• Check the cooling system and the exhaust system hose clamps for tightness.
Inspect both systems for damage or leaks.
• Disassemble and inspect the seawater pump and replace worn components.
• Clean the seawater section of the closed‑cooling system. Clean, inspect,
and test the pressure cap.
• Inspect the exhaust system components. If the package was equipped with
water shutters (flapper valves), verify that they are not missing or worn.
