Diesels don't have plugs, they have Glow Plugs, and they will not light unless you hit the glow plug button. DO NOT shoot oil into the cylinders. You can hydro-lock the motor and bend the con rods.

If you replace the fuel filter, you must fill it to the top with fuel, spilling over. Then, you still might have to bleed the injectors to get it to start.

If the hoses appear dry rotted, replace them.

Diesels generally don't need tune ups. Just routine maintenance. Change filters, change oil, clean air cleaner, make sure the fuel is clean and algae free. Replace the alternator belt, make sure there is no corrosion or leaks.

Diesels are a lot less picky than gas engines. They need clean fuel and air, and cooling water.

What model engine do you have, how about some pics of the engine and the control and gauge panels? This might narrow down what engine you have.

If you have a distributor cap, you have an Atomic 4 gasser.

If not, more than likely a Universal, Westerbeke, or Renault diesel.

Oh, and CONGRATS on the 27!

PICS PICS PICS!!!

Best is to read some general books on diesels, do some study so you understand how they operate.

Myself, I would pull the injectors and do some service work before just cranking it up.

Don't forget to put a new impeller in it. If it's been sitting that long, the impeller is dry rotted by now.

Go ahead and replace the fuel lines now, ALL of them. It may not leak fuel anywhere, but if it sucks in a little air you'll be stalling out real soon. Any pinhole crack anywhere in the fuel system will drive you nuts. Fresh hoses.
