Yanmar does not approve any high performance alternators (generators) attached to their engine.  We provided them with independent evidence that our system did not exceed their specified load tolerances.


They flat refused to even test our system.  Stating that customers should only buy Yanmar engine enhancements.


So we have taken World Wide Insurance to cover the repair or replacement of any engine we damage.  We have not had a single claim and most boat builders accept this.
