mariner service

[Esox]

I am NEW to the boating game, having only bought one for fishing on inland waters. I have a mariner magnum 10Hp 2-stroke and would like to know what needs done for a regular service but more importantly how what needs done IS done. I use the boat mainly during the winter months for the type of fishing I do. I can't read the engine number exept that it's made in Belgium. I assume you check the plugs, oil level (or change it) what's the plug gap, what type of oil in the gearbox, and how you actually get it in. I'm getting quotes of around £100 for a service plus parts. I've had it for about 15 months. Does the pump impeller need renewed? If so, how...Having read this I think I'm asking some very kind person to spell it out for me on paper. If anyone can help by taking the time to detail a complete service for the above, I would be very grateful.

Thats a cracking site but I have another silly question! I have scoured the outboard for an engine number and the only thing I can find is a half battered sticker under the engine with the last three digits 453. Can anyone help a novice. I want to do a service but don't have much of a clue.....don't have any clue to be honest. We are holding a memorial fishing competition this Sunday and I will have to ferry people to the island to fish. I suppose I wouldn't get the service done by then?

HELP!

There should be a plate somewhere around the mounting bracket which will give you the serial number.
If you are doing your own servicing its worthwhile getting a proper service manual.

Apologies Joe. That's where I found this wee sticker. I'm assuming I can't buy the correct manual until I know either the year of manufacture or the serial number?

OK, firstly I'm very definitely not an expert but here's my two pennorth...
On a 2 stroke (so far as I know) there's no sump and no engine oil or filter to change. The oil in the 2 stroke fuel lubricates the engine.
The gearbox, ie what the propellor is attached to, usually has a slotted head screw (or two) which are the drain and refill point for the gear oil. Empty the old oil out and refill with new outboard gear oil. Oddly, they usually tell you to refill from the bottom screw hole until it runs out the top one. Replace the two screws (quickly).
Replace the spark plugs with new ones and keep the old ones for spare.
If you can get at the carburettor, it's usually worth removing the bowl and giving it a quick clean. Don't try and do anything else to the carburettor if you've got no problems at the moment.
There may be a small fuel filter in the line that's worth replacing.
If there are any grease nipples anywhere give them a squirt of grease.
Finally just generally check that all screws are tight and nothing is corroding too much.
If it ain't broke, don't fix it, but the above should keep it unbroke for a bit longer.
I'm sure more expertise on the forum will put me right if I've told you anything disastrous...
Cheers, and good luck with the Irish pike.

The serial number will appear on a metal plate rather than a sticker. (If I read your posting correctly it sounded like a sticky label. Mariner spare parts often have the part number on a sticky label. It maybe that that is what you've found)

If your engine is a 10HP I suspect that it will be fairly recent, because until a few years ago I think that this size engine was described as 9.9HP. Others on the forum will probably be able to give you full details.

The Mariner handbooks seem to be published to cover engines over a number of years so you may be able to pin it down without too much problem.

Tother way around methinks, if it is 9.9 it is likely to be more recent imho.

Thanks. Can anyone else point any closer. We're getting there slowly but surely. Thanks for the help given so far lads.....and lassies. I'm sure you understand the feeling. Never done it before so you're quite apprehensive about tackling something which if done "incorrectly", could land you in deep water. (pardon the pun).
