Rebuild or refurbish of 175TXRB injectors?? Can it be done or go new parts?

[darknstormy]

So I have an independent shop testing my injectors..long story...2 were plugged beyond operation, 4 were spraying eratically. I had received bad fuel, wtaer in my gas, almost 4 gallons pumped out, injectors were spraying water out when shop fuel was used, head gasket failed, cylinder walls stained ...a mess. I've been told by multiple sources, Yamaha cert including Yamaha that water would cause failure and that the pintles would have been scored by the water andafter they've been tested, they're not firing consistently. They shut down and dribble..all of them...I was told that Yamaha injectors cannot be rebuilt and my techs are saying they need to be replaced.
What is the correct answer? I cannot see why anyone would install injectors that are going to fail after they've been cleaned.
