Question: I have a 2004 Mainship 430 with twin Yanmar 6YLA-STP engines. The engines have 950 hours on them; so they are coming due for their recommended 1,000 hour servicing which is going to be very expensive. I was wondering if I could do the 1,000 service on one engine now and service the other engine next year? I will probably only put <100 hours on both engines over the next year. So the hours on the engine not serviced now will still be close to 1,000 hours.
I know 1,000 hours is only a guideline, and the real determining factor of when to service the engines should be their condition and performance. So how do you determine when to do a major servicing like the 1,000 hours.
