Hello and welcome. Biggest bit of advice is Flush it though with freshwater after each use (run it in bucket or on muffs with freshwater just to clean the waterways a bit).

A service will vary dependant on its condition etc.

Usual things you can change yourself is spark plugs, gearbox oil, keep it lubricated etc. bigger jobs (still can be done yourself) will be impeller, thermostat etc.

Post on here anything your not sure on and you'll get very informative advice, free!

Tanks Peter for the info, oh an what is the best 2 strok oil to use and is it best to buy on line?

Best 2- stroke oil? Prepare for heated debate!

Personally I prefer Yamlube. Doesn't seem so "gloopy" as the quicksilver stuff, (so easier to clean spills!) and I've run Yam, Suz, Johnsorude and Mercs on it with no issues.

Whatever you use, make sure it is TCW3 type. The label on the bottle is down to personal preference & budget.

I am fairly new to ribbing and have serviced my own Yamaha 30 hp 3 cylinder outboard several times, it is fairly straightforward. without teaching a granny to suck eggs! I buy a service kit on ebay about £40 this includes plugs,fuel filter,gear box oil and impeller.My top tips would be.

• when you replace the plugs hand tighten initially and nip up VERY carefully ...worth getting a torque wrench and finding the torque setting, mine is 18 llb ft.
• when you change the impeller worth watching this as I made the mistake of not releasing the gear linkage nut.

• oil change very straightforward, 2 screws undo top one "fill level" then bottom one make sure you have something to catch it.check consistancy of what comes out shouldnt be "milky" this could point to water getting into gear box oil ..not good.
• fuel filter easy, unscrew housing remove old filter just push fit
• filling oil , youll need to get hold of quicksilver pump or similar pump in to bottom screw hole until it come out of the top hole then quickly refit the screws and washers.
• check running of engine ESPECIALLY the tell tale!!!!

just one more thing, the clip just shows 4 bolts to separate the gearbox......on mine after removing the trim tab anode there was a 5th 12mm bolt up inside.

oh and worth buying some waterproof greese to re apply to the bolts when re inserting.
