Vintage Tohatsu info needed- now with pics!

[thepetrolist]

I was just given what is believed to be early 1970’s,late 60’s Tohatsu Sea Swallow 5 hp. Anyone got any info about these? Again, I tried googling but didn’t come up with anything. It is one cylinder, two stroke, air cooled. F-N-R gearbox. Three blade prop. Internal gas tank.
It is a non runner at the moment, but I see no reason why it shouldn’t run. Did a quick check up and its got spark and the carb is in good shape. It is quite rough around the edges but I think I’ll repaint it..

Any info apreciated!

The model name is apparently B9A. There really is nothing to be found on google! Seems to me that it is a somewhat rare engine (no, not thinking of value).
I’ll try to snap some pics tomorrow. It’s a real ugly duckling 😆

I have a Tohatsu M5A2 which is exactly as you describe yours. I use mine on a 10F tinny. I also have a copy of a workshop manual, which took some finding. Cant post it here as I cant post pictures.

I bought a Tohatsu parts manual from a deal whom went out of business. I will if your motor is included, but won’t be until either late Monday night or Tuesday evening.

According to their website, Tohatsu was OEM’ing outboard motors for Nissan and Brunswick at various times. Might be a documentation lead in there..

That is true. Nowadays, all japanese made under 30 hp Mercury, Nissan and Mariner outboards are made by Tohatsu.

That is the same as my Tohatsu outboard. If you want a copy of the workshop manual (28 pages) PM your Email address.

I’m amazed at how crude the basic design is, for a motor of the late 60s. The bolt-on, British-style throttle is also totally unexpected – it’s just not like the Japanese.

It must have some real charms, though, as it looks like it’s done more than one lifetime’s worth of service.

My handy-dandy motor bible says the M5A2 is a 1981. Looks pretty modern to me.

That might be so, but my engine is a B9A, not M5A2
