Annual Service Parts Mercury 115 EFI

[npm108]

My engine is currently under warranty and I would like to keep the Mercury 5 Years Warranty going. This means that I have to service the engine at a Mercury dealer, although I am free to buy the parts from anywhere providing they are Mercury/Quicksilver Original.

However the list the local dealer gave me for the annual/100hr service seems a little OTT and I was wondering if Mercury have an official service item list that details what they expect a dealer to change.

This evening I will scan what I was given as the official list.....

If it's a 4 stroke usually gear and crankcase oil, filters, valve lash, plugs, generall grease & check out of entire engine, etc.

the service list should be in your owners manual, when I did tech advise thats the on no one seemed to read.

Here's the invoice from my last service earlier this year if it helps - Mines a 2008 115 EFI with 220 hours.

Hi Thomas - I make that £441.81 or £530.17 with VAT I guess my question of you and others whether this is typical or if there is a big difference between servicing the Optimax versus the EFI?

I do see that of the above pricing £184 was laboour which may have included other work.

Sorry, I should have explained it, MB have a standard list with every part that may need replacing but only charge for what they actually replace, look at the left column and knock off anything with a zero next to it.

No idea about service cost on Optis, I guess there is no engine oil to change.

Fuel filter canister earlier type or element newer
3x iridium plugs either 100hour of being change or check an adjust gap
Impeller plus 2x gaskets
Air filter
gear oil
2 x drain bungs fibre washer
Anodes lower unit and bottom of transom bracket
1 x belt if needs to be changed

Thanks for clarifying and good to know.

So this is what the guy I bought the boat off had done at the 100 hr engine service in April this year.

I have the Brunswick Marine in EMEA owners manual next to me, that calls for the following at 100 hrs/1year whichever comes first:

Engine Oil and Filter
Inspect and check thermostat opening/operation
Check low pressure fuel filter for contaminants and replace if required

Check and replace anodes if necessary
Drain and replace gearcase oil
Check power trim fluid
Inspect battery
Saltwater use - Remove and inspect plugs for corrosion, replace if necessary
Check wiring and connectors, bolts etc

It's only at the 300 hours/3years mark that it states to replace water pump impeller (more of reduced pressure/overheating), high-pressure inline fuel filter, spark plugs and accessory drive belt.

So looking at the attached sheet which I don't think is a Mercury EMEA original document (but stand to be corrected),

- anodes shouldn't be replaced unless needed especially as this boat was trailered each time and not left in the water
- Impeller and related gaskets don't need to be changed until 300hrs or if there is a water pressure problem
- Spark plugs should have been inspected only
- The fin anode is black for some reason....doesn't look like it was painted but it doesn't look like zinc either (is this Magnesium for fresh water? I am in Saltwater?!)

Hi Nick, if it was me I'd do the impeller as a matter of course as if you're in salt water you get a build up of calcium in the water pump which should be cleaned and also if you leave it three years it may be a battle to get the gearbox off and also the bolts holding the water pump down. Apart from that oil and filters, fuel filters and gearbox oil. I'd leave the plugs as they are 3 years 300 hours if its the iridium ones. I'd do the belt at 3 years 300 hrs as well. Anodes should be fine if the boats not left in. Valves should be fine if its an L4NA merc as they have a maintenance free valve train with a chain drive and no cam belt. Should be plugged in to the diagnostics and a general check over and grease all grease points. Hope this helps. Peter.

Peter, thanks for the tips. Interesting read about the impeller and it makes sense, was going to have a look whether it makes more sense to get the impeller kit or use separate parts. I don't like leaving things in other people's hands, whether its my car or boat engine and going on their word that they've done the work you get charged for. Unfortunately too many people in Malta have made too much money from charging customers for work that wasn't done and parts that weren't replaced.

I like to be there and watch/assist as the work is done on my engine which also gives me peace of mind when I'm 15nm offshore that the engine was serviced properly.

@Thomas thanks for the pic with the last service info. Gives me a good basis for comparison.

[peterwhite]

Neil, just check prices to compare kit or separate. Kit has impeller, top and bottom gaskets, face plate, key, o-ring seals for the connector tube and gearbox oil seals. Works out a lot cheaper than all separate but up to you if you want to change it all. Think it's about 35 quid ish ex vat for the kit from memory.
