My new 15hp 2 stroke mercury

[tinker]

I stick to brands with seals, tbh there not much more expensive than the unbranded £5 as opposed to £3. I may use Chinese stuff if the reward is worth the risk, I'm pretty sure the Uk purchased seal kit I have is the same as one from aliexpress. The retailer just holds UK stock for a quicker delivery time. Knock off life jacket.....no thanks.

Usually is a misleading claim. You clearly have never been involved with safety or reliability critical marine, automotive or aircraft supply chains where the issue of copies, items rejected from OE factories obtained from"back door" sources and other variable products are a constant issue.

Often the cheapest items are plain bag or white box offerings with the claim they are "the same as OE"... which is frequently a total fabrication.

I have been involved in way more than you can imagine and I know a rip off when I see one. Others are often easily fooled and fall prey to the 3/4 price brigade

Waffle and bluster! A man on the Clapham omnibus would recognise you as a rank charlatan.

Hes been a busy boy! For someone notorious for posting sh1t advice & rubbish recommendations he claims to be expert in a lot of fields.

Here is a prime example. Pic below is for in effect 2 carb rebuild kits for the Tohatsu 9.8hp 2 stroke and several other engines. The kit contains:

Rubber bowl gasket
Float
Float Attaching bits
Bung for jet hole
Fuel pump rubber
Several other bits and pieces

2 Kits delivered for £14.00 from Ali Express.

Of course you can take your outboard to a mechanic and let them put probably these same bits in but in a different packet for about 25% the value of the outboard or buy these inexpensive parts and have a go yourself. You will learn a lot doing things like this yourself and save a lot of time and money in the future.

>>Here is a prime example.

A prime example of nothing more than you can buy cheap and take the risk.

South Marine is of course a Chinese company using a Western sounding name to reassure the gullible. They are the type of company that would happily brand packets Yamahaha or Suzuky if you bulk purchased. They don't make these parts to any particular standard and have no responsibility to any UK based supplier. They are 5000 miles and a whole culture apart so no big deal to them if your bag of parts prove faulty. You wouldn't have a clue if their gaskets are designed for use with E10 fuel or if their design life is say 15yrs or so like the originals or just 1yr.

There are a high enough proportion of reviews of their parts to raise concerns saying gaskets don't fit, threaded jets have the wrong thread sufficient to ruin your carb and their own replacements carbs leaking fuel when fitted or linkages incompatible with your original. They have confused their Yamaha prop types as one example I notice selling the J1 type as a J type and the blade shaping is dreadful.

So yes they are available, a choice folks can make but don't claim they will be just the same as products in a maker's genuine packet which will go through a very different design, spec, testing and assurance process.

When I have the choice, and because my SIB goes to sea, minimising risk of failure seems sensible.

Please keep making rational, informed comments David, I for one find them very useful.

Not saying it's common but this did remind me of a piece in MCN a week or so ago - like others I'm happy to buy all manner of non-critical boat/bike parts but when service parts like seals, plugs, filters etc are so cheap anyway there is no point:

You do what you want and I will do what I want. Others can of course make their own decisions. It would not be at all right to just hear one side of the story.

Plenty of gullible people love to pay reasuringly expensive. Are you that person.

Perhaps you also need to understand that your way is one way it is not necessarily the correct way

Yes nice to hear both sides of a story.

Engine can still overheat and 'blow up' even when you use OEM parts. Am I correct

So when you pay for 'OEM' Parts how do you in fact know that you are getting OEM ??

[smallribber]

If you had a 9.8 hp Tohatsu. Would you buy the below for £38

Ahh so when the technical discussion fails the plain spiteful nasty stuff comes out.

This could all get rather petty but it's not that difficult to confirm official channels of legitimate parts - main dealer, registered supplier, ask the official UK importer etc.

Twas you that started it old friend. Look a few posts up.

Further was there anything technically incorrect about my post

[Fenlander]

>>>Twas you that started it old friend. Look a few posts up.

Sadly that sums up your whole attitude to this forum... competition.

If you actually read my posts above every one concerned the quality vs price of components related to outboard parts and carb gasket sets in particular. At no point did I dig at any of your unfortunate unrelated life events.

I've no issue with using pattern/aftermarket parts. I've fitted thousands of them.

The issue is with knowing which are good pattern parts and which are garbage Chinesium (and there's plenty of garbage out there). I wouldn't have much confidence in no-name parts from AliExpress though. Maybe it's worth a shot if you're just messing around in the shallows/freshwater etc, but I wouldn't go to sea with questionable parts keeping the engine running.

[tinker]

Little update, rebuilt the gearbox, cleaned and inspected all seems good, no teeth missing and gears engage nicely, just waiting for a price on a Prop shaft oil seal,.apparently there's 4 different types,.ordered one and failed had to trawl through some parts listings then Google the numbers to get the sizes and compare it to mine. These part suppliers never state sizes, just numbers. The fact my serial number label is missing doesn't help.

Carb cleaned and rebuilt.

Block, found a broken pin, flush to the block, ordered a cobalt drill and going to make a jig/guide to help remove and re tap. My attempts to remove have failed, it's only a 5mm pin.

Stripped crank shaft and pistons cleaned and removed any marks with some 600 grade emery cloth, the crank is in great condition really shows the original one up for being a dud. Pity I couldn't use the crank of the new one and the block of the original but there matched pairs so better of sticking to the original setup.

Honing tool arriving today so should be able to sort that out before I leave it all for a week or 2 for some domestic DIY.
