Re: marine wreckers?
There's one kind of like a wreckers out my way david. t's a guy who buys and parts out boats, but it's a 5 hour drive from my place to London. I make the trek 2 or 3 times a year to see family.
I found the one here by asking at a marina. Also know to the independent marine mechanics, who use it a lot more than the marinas.
There must be one close to you, maybe Grand Bend or Sarnia.
