Thank you for this. Looking to buy my first boat and want to make sure I don't get a lemon. Trying to figure out what I need to check. This is one more thing I can add to the checklist that I can do myself.
I've tried that process but it didn't make any difference...that's just not true....I do this daily...been a mechanic for 40+ yrs now...I challenge you to prove it....
Let me see. Hmmm Ahhh, the top spark plug wire goes on the top cylinder, wow that was easy. Also and this is a big also. --> the reason you trip your kill switch on a boat with a CDI ignition and even some electronic ignitions is so you do not burn out your ignition. If you remove your spark plugs and the voltage that would normally go through that spark plug has no place to go it can easily burn out your ignition. It is not enough for that plug to just be in the cap, it has to be in the cap and grounded to metal on the engine.
I usually pull the kill switch which shuts off ignition. I have tried both open throttle as well as closed and it's virtually the same on 2 stroke engines. 4 stroke yes open throttles
I am honestly not sure. You can google it and find it for sure. I know you want no more than 10-15% difference between cylinders. Hope that helps. Tight Lines!
I agree , motor s.b at operating temperature. Thats how you will be running on water. But, i think if motor starts on first shot, and runs smoothly...you probably are ok in compression. But if it gives hard time cranking over....then you should ck out. WDUTHNK
Thanks for your videos. What happen to the Micro-Anchor Power-Pole follow up video? Do you still recommend the Micro-Anchor for the Gheenoe's? What has been your experience with it so far? Please advise. Thank you.
Funny you say that. I have it filmed and getting ready to edit it. Yes I recommend it bigtime. We have not had any issues at all with it. We did lose the nut to mount it in the water but that is because my buddy dropped it and it bounced into the drink. Lol. Thanks for watching and subscribing!!
@@JackedUpFishing Thank you. I am considering getting one for my Gheenoe LT-25. I have read mixed reviews on it. I am also considering a Power-Pole Sportsman II 8' for the Gheenoe. The New 2021 Micro-Anchor version 2 is out of stock until June but the sportsman is available. Do you think the Sportsman's 2 its an overkill?
Torque those spark plugs with a breaker bar.🤣 I love older stuff because of how simple it is. I bought a HF compression tester just because it was so cheap and noticed what you said. What brand is the one you're using? I didn't catch it. I'm guessing you're happy with it.
@@JackedUpFishing oh yea I've came across quite a few like that. So surprised it didn't rip the threads out of the heads. Thats good to know. One guy I usto deal with used the same one and was happy as well.
Looking at a boat this weekend. Does the motor have to be warm or can it be cold? Also does the throttle have the be wide open? Ive had different mechanics say Wide open throttle and others say it doesn't matter and engine can be cold
@@JackedUpFishing does wide open throottle make a difference on a 2 stroke ? The one im going to be testing has a 93 Evinrude 40hp with console steer. Can i just remove plugs then cold test the cylinders without being Wide open throttle? I will be doing a compression test before we lake test it
@@shooter3288 yep 2 stroke fine to pull plugs and test cold. Make sure there isn’t over 10 percent difference between the 2 cylinders. That’s a strong engine too. I have had many of them
@@JackedUpFishing gotcha thats good to hear that those are strong motors. Amd ive never tested with throttle wide open on a compression compression lol
Wow! I noticed a few things I would never do in this video...... Never run an Outboard without water, the water pump requires water as lubrication. If you run an Outboard without water connected you will be destroying the impeller. Next you must bring the motor up to operating temperature to get an accurate reading. 2 stroke, 4 stroke doesn't matter ALL engines need to be at operating temperature! If this dude would warm the motor up first he would get completely different readings!
Actually I have tested that theory and numbers were in fact not that different. And another thing, I never ran the motor. You can turn the engine over either way starter without hurting your impeller. I work on engines and I can 100 percent tell you this is common practice on a 2 stroke.
Just got myself a hull with a Yami 115. Thanks for the vid, subbed.
Awesome! Congrats on new rig!

Awesome glad it could help you out! Good luck on your boat search! Tight lines
Amazing video, simple and clear expenation. Best on the net. Thanks from greece
Awesome 🙏 thx
Great video for anyone checking out their motor! Keep up the good work Bill.
Thanks man! Pretty soon it will be solid fishing videos. lol
That was very informative brother. Great content
Thanks buddy!
Hi from Australia, nformative vid, none of us want to break down on the water, home maintenance can make all the difference. 👍
Thanks for watching ! So awesome! Appreciate the support from down under!
know its an older vid but suggestion is to also open the throttle to full. Allows full airflow and gives a more true reading.
Yep 100 percent correct
I've tried that process but it didn't make any difference...that's just not true....I do this daily...been a mechanic for 40+ yrs now...I challenge you to prove it....
Good video straight to the point thanks for the info.
Thanks and appreciate the comment!
If the seller won’t let you, don’t buy it
That’s right!!!
@@JackedUpFishing my 150 Johnson 2000 year has 150 on every cylinder. It's got 500 hrs run time.
@@JeffreyRust-oq7rw perfect!
A saw the No.3 as just uunder 110 both times. Have a closer look?
Motor still running years later
Great info! 👍👍
Thank you!
excellent video ...

What is the normal operating ranges on a 2 stroke 225 Yamaha 2005. Enjoyed your video. Thank you.
Carl, Houma, La.
Not sure you can prob google it tho
Great clip man, good clips and great info 👍
Thx man!
Good video n explanation. I was taught to warm up the motor first and ground out the spark plug ends prior to testing. True?
I usually pull the kill switch which shuts off ignition. I have tried both open throttle as well as closed and it's virtually the same on 2 stroke engines. 4 stroke yes open throttles
clean 2005! Owner must really maintain and care for it! lol...
😂 😂😂😂
great video man keep it up
Thanks, will do!
For a four-stroke Yamaha is it hard to do a compression test or should I hire someone I'm looking at buying a boat
Depends on size. A lot of them are tough, but the smaller ones are easy to do.
Thanks man. Easy video
Thanks for watching!
I have a 1984 Evinrude 50HP reeding 121 on both. I am guessing I am in the good?
Yeah I love them engines they are hard to kill
My compressions came out to be between 125 130 is that good? Why are mine higher? I do have 150 hp.
Different motors have different specs. If all the cylinders are that close you are good
For a 50 hp Yamaha 2 stroke 2005 should the psi be around 110 to 130 psi also?
I am honestly not sure. You can google it and find it for sure. I know you want no more than 10-15% difference between cylinders. Hope that helps. Tight Lines!
Awesome! So clear. Is it necessary to run water through the lower leg to lubricate the impeller?
Not doing a compression check.

On small engines yes, but on bigger engines it’s a little more involved

Lol I’ve seen people crank them down waaaay too much. Mine was a autozone special bought on a whim. Seems good I’ve had it for few years now.
@@JackedUpFishing oh yea I've came across quite a few like that. So surprised it didn't rip the threads out of the heads. Thats good to know. One guy I usto deal with used the same one and was happy as well.
A mi me dijo alguien que hay que lubricar con un poquito de aceite antes de medir la compresión eso es correcto?
No.
Where did you buy your compression gauge and what is the brand?
You can get them online or autozone also Has them
HI, what is the name of the device to measure the pressure of the boat that you used please to look for it in amaozon
It’s called a compression tester, I got mine at autozone for $35.
Is the motor supposed to be hot or cold for a compression test? Does it matter?
Either works, but if you can do it hot it’s prob better. The main thing is that each cylinder is within no more than 10 percent of each other
@@JackedUpFishing awesome. Thanks for the quick response!
@@KZ-wk4xb no prob!
Looking at a boat this weekend. Does the motor have to be warm or can it be cold? Also does the throttle have the be wide open? Ive had different mechanics say Wide open throttle and others say it doesn't matter and engine can be cold
Cold is fine on 2 strokes, but with 4 strokes I would do it cold and then warm just to see if there is any variation.
@@JackedUpFishing gotcha thanks.

Apparently you're not a mechanic
@@Showmethefish doesn't take much brains to be a mechanic......
5% variance is the norm now
Yeah with 4 strokes, 2 strokes still 10%
@@JackedUpFishing okay literally two sides to every story hard to tell anymore lol
@@brett7794 yeah for sure. Don’t get me wrong, I like 5% or less a lot better 😂. Tight lines
@@JackedUpFishing I hear that! You too brotha 🤙🏽
how do you shut off the gas line to the engine? or we don't need to do this.
You can just unplug the fitting. But you do not have to.
thanks, also I notice you didn't push the throttle to fully open. should we open the throttle to let more air into it during testing?@@JackedUpFishing
the last one was under 110
It was a little higher, and the others if you are getting technical were around 115ish so compression was perfect
open throtle
👍
Dead!
