1989 Yamaha 9.9hp Outboard: Can I get this old 4 stroke running? 

Awesome video and how you breathed new life into an old motor was very instructional too! Appreciate your efforts 💕

Worked out, put a new pull rope, new Impeller, lower grease, then found out the power pack was bad , replaced, took it out ran like a top, still running strong! Thanks .

Nice job..... very good information and I enjoy how you just get with it on your video and not wasting time talking more then what is needed. Thanks

You made this very digestible for a beginner I really feel now I can do some restoration with my new boat it’s old bit looks good so thanks

Bought the same outboard yesterday, $300, gonna follow what you did and hopefully get it running … thanks

This Channel is so underrated!

Great job man that yamaha is quiet 🤫 Chris from OHIO

I have the same motor, has no spark. Thinking cdi or coils. Looks like a fun machine

There's supposed to be a hard clear plastic cover over that plunger on the carb. Mine also looks like it has an electric starter but didn't come with a factory button.

That looks like it has the wires(2 green wires) so you can put a rectifier on it to charge your battery.

I have same motor. I can’t get a compression tester to fit. Bought a leak down tester kit but the spark plug well is too narrow to fit it. Do you have a link for me for one you used? Thanks

Why did you not clean those "dirty" lines up? Why did you not replace those brittle fuel lines to and from the pump? Why did you not ground both spark plugs at the same time (using crocodile clips and wires) so the CDI unit would not be at risk of blowing up? Why did you not take every electrical plug and connection apart and clean them...as corrosion is the worst thing for an engine used in a wet environment? Why did you not immediately disassemble the leg and check the impellor before it shattered and drove all those bits of rubber up into the head and cooling passages?

Congratulations! I used to own the same model in early nineties. Fantastic machine. You will love it. Have you bought this one just recently? I think I saw a similar motor for sale a few weeks ago.

I'll buy that carb!

Good job on this one.What size adapter did you need for compression test?

Very nice video! Everything understandable and clear! QUESTION: Is there an oil filter? Or how the engine oil filtrates ? Please let me know. Thank you in advance!

Can I get a picture of the wiring for the is my wires got twisted in the flywheel and I’m trying to rewire it I’m lost tbh lol I have the exact same motor

when you change the oil on this engine do you fill it all the way up to the line or halfway in the grid pattern on the dip stick? Thanks.

man i just picked one up about 3 weeks ago. didnt have a carb so i though i could source on.. i cant find one anywhere. would you happen to know if i can use a newer 9.9 carb.??

I have a question regarding the same motor but it has controls to a remote control box. How would I find a schematic of how the shift and throttle cables are installed and connected?

why was the compression so low? did you have the throttle body closed and not all the way open?

You Da` man , wish I had your calm and patience to try to do more of my own work on my motors !! Thanks for the encouragement ! I`ve been trying to find more info on this particular motor, theres one for sale, near me asking $1000 OBO ? Is that a fair price ? Supposed to have been fully serviced 3 yrs. ago, pretty much been sitting since ? Never had a four stroke ?? Thanks, Philip.

Were did u get adapter for plugs to check compression also the impeller I ordered on but it was to big link or part number would be a big help thanks I just bought same motor 1988 trying to get it to run.

Anyone else have this outboard or parts for it?

I have a similar 1992 T9.9EXHQ. I put it away in storage, 5 years later when I take it out of storage, I have no spark. I'm troubleshooting with a DVA and I get values that are within spec for the charge coil (105v)and pulsar coil (4.05v), but the CDI output is lower than spec, 60v actual, spec is 95v. Is this enough on it's own to stop the spark? Or more importantly, to warrant buying a CDI ? Love to hear about it anyone has had a similar experience.

What is the compression spec on this motor if you know please 🙏. Great video nicely put together

Ok let's see some FISH!

I haven’t got around to my first ew boat yahmaha 9.9 similar to this outboard it rained a few times any tips?
