It's 100 hours of high rpm in sea air and harsh conditions and load. When we used to have skis we was doing them at around 20-50 hours depending on usage. I've pushed mine to around 150 hours with out a oil change but I spend half my life on tick over getting out poole harbour from Wareham, and been so busy having fun I lost track but in terms of cost of a oil change and cost of a engine rebuild I'm going start doing mine every 50-100 max
