Low oil pressure alarm; engine may shut down shortly after start; oil pressure gauge near zero.

Safety: Running with low oil pressure can destroy the engine. Do not continue to operate until the cause is found.

• Check oil level: With the engine off and level, use the dipstick to verify oil level. Top up with the correct Volvo Penta-approved oil grade if low. Investigate for external leaks at the oil pan, filter, and seals.
• Replace oil filter: If the filter is old or unknown, replace it with a genuine Volvo Penta filter. Cut open the old filter to inspect for metal particles, which indicate internal damage.
• Verify pressure with mechanical gauge: Install a mechanical oil pressure gauge at the sender port to confirm actual pressure. If the mechanical reading is normal, suspect a faulty pressure sensor or wiring.
• Inspect for internal issues: If true pressure is low, the oil pump or engine bearings may be worn. This requires professional diagnosis and likely engine repair or overhaul.
