Yamaha F100AET 4 Stroke regulator CDI fire/meltdown

So, worst nightmare really. In the Helford river in Falmouth and the motor conks out on my Ribtec. Didn't restart so I removed the hood to be welcomed with plumes of thick grey smoke. Panic stations and fire extinguishers deployed it eventually died. Looking at the damage the regulator has lit up the CDI. Now, I've had a quote for 1800 to source parts and repair. Firstly, does this seem accurate?

Secondly, I'm fairly handy with a spanner and know my way around outboards on a basic level. Is this something I can undertake myself?

The cause has been suggested that the maintenance free calcium battery has slowly fried the regulator and it was a ticking time bomb, the motor is 8 years old.

All advice and help is very much welcomed.

The rectifier is a known problem on F80/F100 and they all seem to burn out after 10 or so years, probably changed ten or so but never had one take out a CDI unit. The replacement rectifiers are a revised parts.

Dead easy rectifier and CDI are just held on with m6 bolts.

If it's any consolation the same thing seems to be happening to Suzuki DF140's

Thanks all for the replies. It's only after the event that you learn of the F80/F100 woes. So, the rectifier and CDI are just plug in and play?? Does anything need setting up?

If the chap isn't willing to break these parts where would you suggest buying new from?

Thanks chaps 👍🏻

That's very helpful, the regulator looks a doddle. It's just the CDI I can't be sure of. More research required from me!

As I have F100, glad to know future problems - as mine is getting to that age.

Yeah, I read that! It's a b**tard really because you don't tend to find these things out until it's gone up in smoke. There's been a suggestion that it's down the maintenance free batteries but that could just be speculation... So unlucky it fried my CDI. I need to try and get this done by next week for when I'm away. It only lasted 2.5 days!......mind you it was impeccable in that time...
