Smile Quite a Project!

Nick -
Looking through the manuals & other documents I found that there are electrical schematics shown in the Mercruiser 3.0L / 3.0LX installation manual. Since the boat you are rehabbing came with the 4.3L engine I am sure they are in that manual as well. Something that may be of help. Keep up the great work!

Hi all.

So engine has arrived, it's stripped and free turning, heads away for pressure test and rebuild so I have the job now of removing each piston and ring set. Cranks good, no con rod damage just water ingress as no flapper valves were fitted to exhaust. Manifolds and Risers seem ok and just need a clean up...may change them anyway but we shall see.

Some more pictures in the album ( https://photos.app.goo.gl/H2VLhDb9Y4QyRyFF ) don't know if it tells you automatically. New Ignition/key and bow lights turned up today. Dean are the manuals on here? I have a few issue's so I'll post the pictures and maybe you guys can point me at the correct item please. Very difficult to find things when you don't what they are called and good layout diagrams are hard to find.

As an extra note I found the manuals on the forum here Dean but still need some parts identifying so will snap those later.
All the pistons are free, rings off and followers are clean. Heads are being refurbished and Head Technique say all should be fine...

So in this shot, right down at the front near the crank is a plastic bottle with connections to the water system. It's cracked and I can't find a name for it to order one...I'll try and get another picture of it later.

All help gratefully received...

Yes, drain trap.

The engine is equipped with Mercruiser’s single point drain system, basically only one plug to remove to drain the entire coolant system.
