Tohatsu 3.5 2 stroke oil capacity

[Enjay]

I inadvertently drained the oil from the lower gearbox of my auxiliary engine in the mistaken belief that the impeller was behind the front plate. I've got the oil but it didn't come with a tube which will allow me to pump it in from the bottom hole.

Does anyone know what capacity of the gearbox is on this 3.5 hp 2 stroke M3.5 B2 3FO so I can fill from the top?

Thanks

The manual looks to say 180ml.

Thanks Fenlander. That's great and good to have a copy of the manual which I couldn't find.

Why wouldn't you get the right tubing parts, and make sure the job is done correctly? Not completely filling to the proper level could cause issues.

What kind of oil container did you get? If a squeeze tube you can often just push the tip into the hole and squeeze it out. A small cone that fits into the threaded portion of the filler port can be utilized too, although a pump is often needed for non flexible containers.

Fill from the drain hole until it comes out the fill hole, new fibre washer, etc.

All done thanks. It was a car intended container, but with a big squeeze and a tray underneath it did fill from the bottom.
