I would ask a yanmar dealer. Years ago I put 10w-40, instead of 15w-40 in a VW diesel and destroyed the engine within 1000 miles. Short term 5 hours it should be ok but I am not an expert.

Changed oil today and when old oil drained realized he bought synthetic 15w40. Have outing today and no time to get regular oil. Plan to drain and change later this week to non synthetic Is this an issue?
