I think the OP needs to settle down. Most boat companies went through the ringer recently with their dealers. Here in Sacto we had Ultimate Watersports(Malibu) and I think it was Capital Watersports (Mastercraft)
Those 2 dealerships would have made you think that Malibu and Mastercraft were the worst boats ever...if you were dumb enough to blame the manufacturer for bad dealer ethics. Sure, it would be nice if the manufacturer had such control over a dealer as to impose their way of doing business, but the reality is, they just want dealers because they need to sell.
This is a dealer issue...and hopefully Sanger will see this thread and try to change some things - if they are things that can be changed. Some things just are out of their control, though. There have been posts here of reps from Sanger flying to different states to help guys with issues they are having. For being the smallest, least advertised wake boat company, they are definitely one of the most stand up as well.
The reference to how bad suppliers are is definitely a way of the times. Nobody is stocking anything because it costs money. There is almost no such thing as a stock room anymore.
Take a deep breath. Realize that some things are very tough to control, and try to understand everyone else's struggles. The fact that the dealer missed the bent shaft doesn't surprise me at all. I do feel your pain, though. Summer is here now, and you want to be able to enjoy every second of it.
Just remember this in your own work life. When someone needs something from you, drop everything and make sure they are incredibly happy and taken care of every time...even if it means pulling some back-ordered, hard to get part out of your never region...
