Extra charges apply. This is a used Marine turbo off a running engine with only 550 hours, it turns freely and smoothly, there is some rust at the exhaust flange and the seals may need replacing.
Shipping weight is 45 lbs. I feel this is a good serviceable turbo. Same day shipping in most cases.
However before installing it I would change the seals and the snap ring that holds the compressor housing because it has a tab missing. The rust at the exhaust outlet should't be a problem as it wan't leaking exhaust.
