Bought a Solas prop for my bass boat, it was delayed three days due to shipping problems unfortunately I missed a tournament this passed week end. The right prop arrived but the wrong thrush washer,( item description said it was needed for the prop), but upon opening the prop package a notice on the prop blade said to use the one on the motor or referenced a different number part. Oh well, bought a new Mercury one locally and I'm up and running. Will still buy from Iboats
