Rydlyme my 1998 Yamaha 2 stroke, motor set off overheat alarm I’ve 5k rpms

Overheating Yamaha outboard

[@jrbuch]

Fellow Yamaha owner, going to try doing this exact thing on my motor in the next week or two. This sounds like it was a winner.

[@jrbuch]

Update: Also have a Saltwater series, was throwing an overheat alarm at high RPM, my results were exactly the same as this video. Big improvement, lots of gunk out of the motor.

[@paulbrodsky587]

Update, after a hard 40 minute ride in 88 degree water the alarm didn’t go off, so I say this was a winner of a fix

So after you Rince with fresh water, then run fresh Rydlyme again and measure the PH if its still rises there is still scaling and salt its eating away in all the ports and such, if its still rising keep flushing till its stops rising and it will look like new where you cant get to without a full tear down and rebuild.Glad to see someone else not fooled by Salt a Way. I won't post my link unless you want to..

I can sense that the Rydlyme do what it supposed to. However I'm bit concerned on the outbourd internal zinc anodes. Rydyis Hydrochloride acid. It will have a mild reaction with aluminium (subject to ratio mix). However hydrochloride WILL have severe reaction with Zinc. In this video, the smoke from the exhaust port are actually hydrogen gas. I'm not too concerned on the aluminium block as it eat a little away. But the zinc is something to concern. How much has the zinc anode been dissolved by Rydlyme?

[@steveperdueshowtofishingti2172]

@JL-se1dp it's a 2 stroke..that's the smoke..it diluted, and not all engines have internal anodes. If you do. Simply remove them with the thermostats and rinse away.

This looks a lot easier than dropping the lower unit and doing it this way through the flush port. Besides removing the thermostats, did you get any sediment clogs in the telltale? Or did you just detatch the telltale hose as well so it also dripped into the bucket?

[@joseph87328]

The water will go all the way to the thermostat location? without taking off the lower unit and using the tube off the impeller? I was going to drop the lower unit as I saw in another video.. This looks much easier using the flush adapter off engine.

Nice video, is that a power tech scd3? What pitch and speeds are you getting

[@themagicm]

Fixing to try this out.

Hi, i’m writing from argentina. I think I have the same problem of the vw tiguan, that you showed on a short video. Could you say me how to remove the side panel of the central console?

Did the vinegar permanently discolor your SS prop?

Where did you hook the hose up at?

to the fresh water rinse

[@galileafishing]

Hey buddy what model is your Yamaha

[@tcap7917]

looks to be the yamaha 150

[@dannynone2784]

What dilution ratio did you use?

[@paulbrodsky587]

I used a 1/3 hp pump from Amazon, i believe 3 gallons of rydlime to almost 5 gallons of water, hasn’t overheated since I did it, even pushing it hard

[@hectortorres7693]

What pump is that? I’m having a clogging issue in my Yamaha 150 2001

[@paulbrodsky587]

Used a 1/3 hp pump from Amazon, I think it was $55

[@paulbrodsky587]

@@hectortorres7693 make sure to take your thermostats out, and run the pump before you put the housings back on to make sure your getting to the top, I tested with water before I put the rydlym in to make sure it wouldn’t be a waste
