Re: Breasting my fin keel? Help please.
down, someone used to sell those air bladder lifts for CARS to be used as jacks, complete with a little compressor. I don't know if they're still being sold and I'm sure they weren't "commercial" grade, but that's something to consider. I've also heard of folks using a basketball (thrift shop!) to lift an engine a few inches, so maybe there's something too.
