Possible Cause

Remedy

Boat overloaded or improperly distributed. Reduce load or redistribute more evenly.
Boat bottom fouled or damaged.

Clean or repair as necessary.

Electronic fuel system fault.

Have electronic fuel system checked by a Mercury Diesel authorized repair facility.

Incorrect Engine Temperature

Possible Cause

Remedy

Water inlet or seacock closed.

Open.

Drive belt loose or in poor condition.

Replace or adjust belt.

Seawater pickups or sea strainer obstructed.

Remove obstruction.

Faulty thermostat.

Replace. See a Mercury Diesel authorized repair facility.

Coolant level low in closed cooling section.

Check for cause of low coolant level and repair. Fill system with

proper coolant solution.

Heat exchanger cores plugged with foreign material.

Clean heat exchanger. See a Mercury Diesel authorized repair

facility.

Loss of pressure in closed cooling section.

Check for leaks. Clean, inspect, and test pressure cap. See a

Mercury Diesel authorized repair facility.

Faulty seawater pickup pump.

Repair. See a Mercury Diesel authorized repair facility.

Seawater discharge restricted or plugged.

Clean exhaust elbows. See a Mercury Diesel authorized repair

facility.

Seawater inlet hose kinked (restricted).

Position hose to prevent kinking (restriction).

Use of improperly designed hose on inlet side of

seawater pump allowing it to collapse.

Replace hose with wire reinforced design.

Faulty thermostats.

Replace. See a Mercury Diesel authorized repair facility.

Low Engine Oil Pressure

Possible Cause

Remedy

Faulty senders.

Have system checked by a Mercury Diesel authorized repair facility.

Insufficient oil in crankcase.

Check and add oil.

Excessive oil in crankcase (causing it to

become aerated).

Check and remove required amount of oil. Check for cause of excessive oil

(improper filling).

Diluted or improper viscosity oil.

Change oil and oil filter, using correct grade and viscosity oil. Determine cause

for dilution (excessive idling).

Battery Will Not Charge

Possible Cause

Remedy

Excessive current draw from battery.

Turn off non‑essential accessories.

Loose or dirty electrical connections or damaged wiring.

Check all associated electrical connections and wires (especially

battery cables). Clean and tighten faulty connections. Repair or

replace damaged wiring.

Alternator drive belt loose or in poor condition.

Replace or adjust.

Unacceptable battery condition.

Test battery.

Remote Control Operates Hard, Binds, Has Excessive Free‑play, or Makes Unusual Sounds

Possible Cause

Remedy

Insufficient lubrication on shift and throttle linkage

fasteners.

Lubricate.

Obstruction in the shift or throttle linkages.

Remove the obstruction.

Loose or missing shift and throttle linkages.

Check all throttle linkages. If any are loose or missing, see a Mercury

Diesel authorized repair facility immediately.
