When I first purchased my IP Estero 36 I purchased two spare fan belts for the
Yanmar 3JH4E
engine based on info from the
chandlery. When I went to change the fan belt I found that, due to the
alternator upgrade the belts were too short. They are
Yanmar Genuine Part number 25132-003800 and cost me $11.95. I don't want them to go to waste and I don't want them laying around for another 2 years. If anyone can use them, let me know. They are FREE but if someone felt the need to defray postage that would be all right but not required. BTW I took the old belt to NAPA auto store and they had an identical replacement. I now have two spares that fit.
