Re: Diesel engine install
Don't do the final alignment until you're in the water.. few boats sit on the hard exactly as they do afloat. Since it's a reinstall of original the rest should be easy.
You might consider leaving some parts off - alternator, exhaust manifold, etc, ie things easy to put on later and they'll lighten the load and make a smaller package to slip down the companionway.
