Bonus: Engine Work

General Tips on Tools

We look at packaged tool kits versus individual tool purchase, cheap versus quality tools, and ways to carry and store tools.

The 90% Toolkit

We cover a selection of basic tools which any maintenance conscious boatowner will need to have on board.

The 10% Toolkit

We explore more specialized tools which are essential for many maintenance tasks, and some that may be required in more extensive work.

Spare Parts

We discuss different philosophies for spare parts and look at how Nigel's approach has evolved over the decades.

Cranking Problems

In this lesson we see how to diagnose why an engine will not turn over when the ignition key is turned, and mechanisms to bypass or fix failed cranking circuits.

Slow Cranking

The engine is cranking, but only slowly; we find out why and how to speed things up.

Getting Water Out of the Engine

If seawater enters an engine and locks it up, we learn how to remove the water and get the engine running again.

Engine not Firing

We find out why an engine will not start even though it is cranking OK, and learn how to get it running.

Smoke Diagnostics

We explore the different colors of smoke that diesel engines create and what they mean.

Overheating

We look at common causes of engine overheating and how to fix them.

Other Problems

We investigate other common engine problems, including misfiring and vibration, and the likely causes, along with those we can fix and those that will require professional assistance.

Electrical Issues

We diagnose common problems with charging circuits and conventional (analog) gauges.

Engine Preparation

We describe basic layup maintenance and discuss if it is needed at every layup.

Cooling System

We discuss both freshwater and seawater layup maintenance and procedures, and winterizing in cold climates.

Longer-Term Layups

We investigate additional measures which may be taken to protect an engine for extended layups of a year or more.

Valve Adjustment Mechanisms

We discuss different valve and camshaft arrangements and the likely valve clearance adjustment mechanisms.

Establishing Cam Position

We describe how to turn the engine over to put the piston in the correct position for valve clearance adjustment.

Adjustment Process

We describe the specific process for setting valve clearances.

Engine Alignment

We provide insights into the process of engine alignment, which is vital for efficient power transfer from the engine to the propeller shaft and for the longevity of bearings.
