How to perform routine engine maintenance

In this episode, John Gamlin from our exclusive service department VesselTec explains the simple steps for an engine inspection. John goes down into the engine bay and walks us through WOBBLES and what to do if you find something abnormal.

This demonstration is done on a Lagoon 42 with 2 Yanmar Diesel Engines. Processes may differ depending on your engine type and make.

BEFORE STARTING

Isolaate the engine by turning it off
Take off any loose clothing or tie up hair (if the engine has to be on)
Do a general inspection for anything that might stand out – smells, leaks, excess fuel or water in the bilge.

How to perform routine engine maintenance

WOBBLES

Water

Salt Water System

Turn off water flow
Check strainer and empty debris
Check impeller for broken vains (if issues persist)

Fresh Water System

Check reservoir fluid levels
Open radiator cap and check levels, colour etc.

Oil

Engine Oil

Pull out dipstick
Clean dipstick
Put the dipstick back in (all the way) and back out
Check oil level and colour

Transmission Oil

Pull out dipstick
Clean dipstick
Put the dipstick back in (but do not screw) and back out
Check oil level and colour

You want your oil levels between the minimum and maximum markings (do not overfill). Colouring should not be milky (this could mean there is water inside), after a bit of use it should be black but not too black or thick.

Battery

Check connections and movement, if loose use a spanner to tighten.
If you find corrosion use a wire brush and then apply a protectant.
Also, check connections on battery switches

Belts

Check it is not fraying
Check it is not too loose or too tight (check mechanic what deflection it should have)

You may need to take off a belt guard to get to this area.

Leaks

What to look for…

Water
Oil
Salt crystals (this indicates salt water has been in the area)
Corrosion

Areas to check…

Where hoses terminate
Check filters
Check other components e.g. gaskets

If you find any leaks attempt to find the cause, tighten anything that may be loose and clean the area so that you know whether the issue has persisted when you next check the area.

Sound

Turn engine on
Go to the side to see the water
Ensure there is a steady flow of water pulsing out

Exhaust

Ensure sound is smooth
No bad vibrations

If the sound is unusual contact your mechanic.

How to Trim Upwind – Basic Sailing Techniques

In this blog, we will look at how to trim your sails when sailing upwind. Sailing upwind is classified as sailing at any angle lower than 90 degrees to the wind. Sailing directly into the wind is not possible; therefore, to sail in the direction of the wind, you must continuously tack in a zig zagging motion.
