Trying to figure out what I just bought? M9.9 B2

[TwoRivers]

Had the week off to do some fishing and impulsively bought a Tohatsu M9.9 B2 hoping to upgrade from my 1958 Evinrude 5.5 Fisherman.
The motor has electric start and it's been converted to a stick steer.
I've spent several hours pouring over the threads and google searching to find out what year this thing was made and if any parts are available?
I haven't had it out yet because the round end of one of the clamp screws that hold the motor to the transom is broken off? Is this something generic that I can get off another motor or at any marina?
Is there some information anywhere (I'll pay for it if necessary) that explains the difference between the different models?
Here's what's on the side of the motor:
M9.9 B2
50050 355A
Thanks in advance

Most parts are not available for one that old. You can go to www.internetoutboards.com and download a parts manual...And see the years that it was produced.

Be advised: The 9.9B is long obsolete. Production stopped in the 1980's

No carbs are available, though a few internal carb bits may be had, depending on which carb you have.

The good news: Water pump kits are still available.

If you want to wrench on this motor (or any motor for that matter), I would recommend you start with the Factory service manual (not an aftermarket manual), available from any dealer (including me.)

The screw kit is available, but not inexpensive: 3V1Q621050 CLAMP SCREW KIT $66.67
If all you need is the "washer" pad that presses against the transom, that would be 332621010M PAD, CLAMP SCREW $2.99

You can call Tohatsu America at 214 420 6440, and they may be able to tell you the year of manufacture.

Thanks for the response. I spoke with a local Tohatsu dealer today and he estimated the motor to be an early to mid nineties? It has the gray case he said the earlier ones were blue?
I read all the posts about the Japanese relegating older (80-90s) motors to obsolescence and I know they do that with automobile engines too. But, I have a 1958 Evinrude 5.5 that I can get parts for at a NAPA auto parts store ???? It runs like new.
Anyways, another issue's come up. The motor is too long for my boat.
I have a 14ft. Meyers Pro. Meyer's website says that the Pro takes a long shaft. Turns out I need a short shaft.
The local dealer said he could replace my transom to accommodate the long shaft for around $350.
Any opinions?
I just wanted to do some fishing.

Better buy a long shaft transom mount, should cost much less.

Happy Boating

Measure the transom to confirm what shaft length you need.

Re: Trying to figure out what I just bought? M9.9 B2

Thanks guys for the info. I measured the transom and it's 16in. Could you recommend a source for the "Long Shaft Transom Mount"?
This seems to be a sweet motor. The local dealer told me he sold hundreds of this model and reported very few problems. I'd like to keep it if possible.

Hey Two Rivers, Been there done that on my 14" Starcraft. I got a good deal on an electric start 15hp long shaft 4 stroke mercury (made by tohatsu) I had to replace the transom anyway (original on a 1961 boat) It was a pain and cost me $75 for marine ply epoxy and hardware. total was about $110 and 3 or 4 days of work. I find that I don't have to worry about back wash comming over the transom anymore. It was worth all the trouble, do it!!!

A minor correction to a myth. People think that because a part is available for an
old Evinrude that somehow that translates that parts are available for the engine. That's not really accurate. A lot of the older model Evinrudes used ignition and carburetor parts common to other types of internal combustion engines. So you will see a handfull of parts available for some older model engines. But, in general, you can look at those older engines as something to be admired and kept as a momento rather than something that should be depended on. I loved my little 3 hp 1963 Johnson right up to when it went bye bye. It was a great little engine. But, by today's standards, it was a POS.

So you have a short 16" transom and a long shaft motor right ? You need something like this. Check marine stores. It's much easier to chop transom down than to rise transom up.

Happy Boating

With head bowed and speaking humbly:
Zen Master, I see you're from Tampa and live by the sea. I'm a hick from the hills of SW Pennsylvania. Here we don't depend on our outboards. We have fun with them. Heck, I'm lucky to get out ten times a year on my boat, and, if I break down, I enjoy the adventure. We don't throw things away here, we maintain them and fix them if they break. If it runs when I get it, I keep it running.
I just sold a 1988 Volvo, 240DL with 316K, guy was smiling as he drove it home. My daily driver Saturn wagon has 280K on the clock. Tow vehicle, Chevy Silverado checks in with 170K. I'd drive it to Tampa today to go fishing with you?
In Japan, I'd be taxed for operating these high mileage engines. Glad I'm an American.
I also ride dirt bikes. Two stroke Japanese bikes last forever and many woods riders here are going back to them. Parts are readily available. My neighbor can rebuild a top end in less than an hour. It takes me a weekend.
In my hillbilly universe an early nineties two stroke outboard has years of use left. I view the obsolete relegation of these engines as a poor business decision.
But, I agree with you. I wouldn't go to sea with my old Evinrude, but I'll bet a lot of people do.
And about your 3hp Johnson? If you loved it so much, what broke so bad that you couldn't fix it?
Thanks for your contribution to this board. I mean no disrespect.

That looks good. Did you make it?

Re: Trying to figure out what I just bought? M9.9 B2

Bye bye = stolen It was a great engine, but, by today's standards, it was leaky and used a lot of gas. It also required a lot of maintenance in that the points had to be cleaned once a year and I went through multiple condensers and coils over it's life. All of which were and probably still are available since they were used on multiple engine platforms. The Asian mentality has been that outboards are a tool with limited life so they just don't think that parts for a 20 year old engine need to be available. I disagree with them as well

Re: Trying to figure out what I just bought? M9.9 B2

its called planned obsolescence. its intended to keep the economy going. Its not just a Japanese / Asian mentality. It is a universal capitolistic mentality. you have a tool, you use the tool, tool wears out or breaks, you BUY a NEW tool.

Regarding old Merc and Johny-Rude parts. one of the reasons you can get parts for these motors is because there were millions of them made, and the aftermarket parts world is supporting them, generally not the OEM's. Sierra and other aftermarket suppliers make the replacement parts you find, and it is generally fuel system and ignition parts (maintenance items). for example you wont find a cowl bracket or a prop for a mid 50's merc Mark 20 or a late 50's Evenrude anywhere but Ebay and craigslist. BTW, Sierra parts and some mallory parts are carried at NAPA, and carquest, and............
