Ordered new Solas prop from iboats. Arrived in about 3 days. As soon as I tried it I noticed a lot of vibration at all speeds. Called iboats who gave me a phone number to contact Solas technician. He said this rarely happens, told me to get back to iboats for a RA number to return the prop and they would most likely send me another prop under warranty. Got RA number, sent prop back to Solas, cost $25, waited 2-3 weeks and iboats credited my card for the original cost. Whole deal took about 6 weeks. So, don't have a new prop, am out $25 (not refunded). Will now buy a new prop locally and will never order from iboats again.
