Outboard maintenance

I have a two stroke 25hp tohatsu outboard. I wanted to know what the best product is for protecting my outboard.

After checking under the cowl, I saw that some salt had built up ontop of the pull start and other parts. There are also 1 or two areas where some surfact rust has built up. I am planning to do a though clean. I have a fine wire brush which came with the outboard. But obviously I want it to stay looking nice and clean. I have seen the quicksilver protection spray. Will this do the trick, or is there a cheap or even more effective product I could use.

Also, I have been told by a number of people that annual services are just a scam to get you to pay out. The outboard is working fine e.g. pumping water well etc. Would it be a good idea to buy the service kit and change the impeller, gear oil, spark plugs etc, or shall I just go by the phrase 'If its not broken don't fix it!'

Would it also be a good idea to grease the prop shaft regularly?

Thanks for help

Henry

Try this:- http://www.ebay.co.uk/itm/Action-Can...-/271111241466

Does the same job as QS corrosion guard.

Whoever's telling you that is a muppet.

Yes, buy the service kit. You won't know if something's wrong 'til you break down if you don't at least inspect it and regrease everything.
Yearly gear oil changes are important too. You won't know if there's water in the gearbox unless you do them.

hi henry, the wire brush will be brass & is for cleaning the plugs. whatever else you dont do do not neglect the gear oil, change twice a year costs very low & grease the prop shaft, you dont want that seizing, spray power head with wd40 if you want to save a bob

Personally I change the impeller every year, it may sound a bit much but for 20 it gives me piece of mind, it's also a chance to drop a little lube on all threads on the pump, gearbox bolts and the prop shaft splines that mate with the crankshaft. Whilst its on the bench I change the oil and grease the prop hub splines replacing the split pin while I'm at it.

As for the engine, it's just a check/replace affair, plugs, filters, leads ect. A little lube on all pivot points helps too.

Is there a decent thread on servicing a small 2 stroke engine?

The service kit come with
1x Tohatsu 345-65021-0 Impeller

1x Tohatsu 346-02230-0 Fuel Filter Assembly

2x Quicksilver Premium Gear Lube Tube 237ml (92-802844Q02)

what else do I need? They are asking 59 for this, is that reasonable?

Are these people who also dont service the car or anything else!

as others have stated some jobs must be done and it would be silly not to, but as for who does it, well thats your choice in the same way some people service their own car and some use a garage. Having said that, it does tend to be a but more fun than calling the AA when your outboard stops working so if you do go down the DIY option just dont muck it up

oh this might also help

thanks for all of the replies. My checklist is:

- service engine by changing spark plugs, gear oil, fuel filter, impeller
- clean any surface rust, salt or grime from the engine
- spray engine with anti rust fluid
- grease prop shaft

Sounds ok?

Grease all grease point , grease spline When offering back up to power head after impeller change. Clean stainless insert in water pump housing of scale grease all mating surfaces on water pump housing. Grease the bolts for the unit to mid section . Basically grease the shit out of everything

For what it's worth....bought mine last year (mariner 60 2-stroke) from a dealer who swore it had been serviced. It was temperamental all season. Had if properly serviced over the winter and its like a completely different engine - starting, idling, general running all better. Worth the money for the peace of mind. I'm no mechanic though so wouldn't even attempt self service - too many bad DIY experiences which ended up costing more money in the end.

well, i am only looking at replacing the really simple things such as the gear oil and impeller. I wouldn't attempt anything such as stripping the head
