servicing yanmar

[ghostlymoron]

I need to service my engine before re-launching. What parts really need replacing? It's a 2GM20F.

Its all in there......

If its been running OK then - Engine oil & new engine oil filter; Replace engine fuel filter including the sealing 'O' ring; Replace raw water impeller; Check alternator & Raw water pump drive belts for wear - replace if at all uncertain; Check gearbox oil.

Visual check for any leaks etc.

Not part of the engine but change primary fuel filter assuming you have one.

That's about it.

Add the tappet clearances too

Don't forget the two anodes, mine normally last about two seasons. If you phone Marine Power ( http://www.marine-power.co.uk) they will sell and deliver to you a kit with all the bits you need. You may need the age or serial number of the engine for the impeller as they changed the pump about 8-10 years ago.

In addition to above would inspect all hoses carefully for signs of wear if any detected replace. make sure antifreeze / coolant levels are appropriate and clear raw water filter.

- and don't forget to check the exhaust elbow for corrosion and carbon blockage!

Are there anodes on the fresh water cooled ones? Pretty sure mine hasn't got any, but prepared to be proved wrong /forums/images/graemlins/smile.gif

Re anodes comments from Georgio - there are no anodes on the 2GM20F as its freshwater cooled - there are on the 2GM20 raw water cooled

 

[Georgio]

you are quite correct, I have the raw water cooled version.

Doh!
