Tohatsu 9.8 2 Stroke Service Video - Part 1

[Steve509926]

I've done the first part of the service on my 9.8 Tohatsu.

Its the first time I have serviced an outboard and I wanted to show others who have never serviced an OB before how easy it is.
No doubt I will have made some rookie errors and/or done things differently than some seasoned pro's, if I have, I'd be grateful for some feedback.
Also, has anyone any suggestions as to what the white deposits are as shown in the first part of the video.

That white corrosion fits in with a little used sail boat locker motor and is nothing to worry about.

I've noticed across all makes of portable outboard if crusty white corrosion is to appear anywhere it is usually at the head/block interface. I think it's where the face edges are unpainted but not 100% covered by the gasket.

If it is ever present on a used OB I buy then I gently remove with a small brass wire brush. If the paint is missing to any degree I replace that but usually just spray with corrosion protection or WD40 oil of some type.

The video is fine and I agree with not stripping that very clean carb as it's been running well too. Look forward to part 2.

Thanks for the white corrosion/deposit explanation it makes complete sense.

I'll add that explanation & WD-40 protection into the part 2 video.
