Cdi Unit For A 2 Stroke Triple

A little bit off forum but someone out there probably knows the answer.

A few years ago I acquired a small (16') boat powered by a Yamaha outboard motor (849cc, 3cyl, 2-stroke. 60hp) which I reckon dates from the late 80s. The engine did run and the boat was fine but it was only used the first summer we had it and then after that it sat there unused as I was always just too busy. Anyhow, this year I'm (almost) fully retired and have the time to use it so I thought I'd get it ready for the water . Unfortunately, as I'm going through it to make sure everything's OK and recommission & refurbishing various bits and pieces I discover some little fecker has stolen the CDI unit! Unbelievable.

I've had a look around and it seems, if you can even find one, a replacement costs anywhere from £500 to £1000, no wonder someone nicked it!

That got me thinking, basically it's a simple 2-stroke, carb fed, 2T oil injected engine; max revs 5000; peak power produced between 4500-5000; it's got an electric starter but how complicated does the CDI unit need to be? There is probably a stock, off the shelf, readily available, unit that could be put in its place.

Does anyone have an ideas, suggestions please?
TIA.

 

I suppose a further question has to be will any CDI unit do, provided it's for 3 spark plugs/cylinders? When I was looking at the official, like unicorn, Yamaha ones they seem to have different part nos for the 50hp/60hp, 70hp/80hp and 90 hp engines, yet they're all 3 cylinder 2Ts just different displacements and carb sizes.

 

You're helping fantastically, thanks for those links, I'll follow them up. The 2nd one is not quite the right model but hence my question above, how different can a CDI unit for one 3 cylinder 2T be from another? I'm going to contact the first link to see if he has one as he's a breaker. Thanks.

 

It could be the 'marine only special' really boils down to the fact that stainless fixings/connectors are used everywhere to inhibit corrosion it being exposed to salt water etc. Certainly the fixings/fastenings all over the engine unit are in as new condition, thanks to being made of s/s, and that's on a 30+ year old engine exposed to salt water. It's more than can be said for my 748 left out in the rain

 

Thanks I'll check them out as well, although I don't need all the add-ons, just want a CDI unit that will operate/control a simple 2T engine.

 

Thanks for the link, what's the price guideline?

 

Thanks Chris

 

Thanks for the link. Mines a 60FEDO, which simply means 60hp, electric start, manual tilt, oil injection. Year code is V so it’s either 1997 or 1977
