Thank you sir. Straight to the point 🤙

We just found you. Best videos we have seen. We have had this problem 2 times on a fairly new boat. Had fuel tank polished again he said water was coming in ptrap because of location. We are going to move ptrap the one we have is attwood do you reconmend a vent p trap we lost our confedence in attwood products and jeanneau dealer doesnt want to help even though it is a 795 jeanneau. Or is you know who to contact. Thank you for you help

Is it okay to install a new fuel filter without a blind connector if the primary filter in the boat is fastened and the engine filter does not have a blind connector? Thank you!

This is not unique to 2017-2018 150. The newer optimax models also had this same setup, and all 2015 and up mercury outboards from 115-400hp have a similar design. Usually this fuse fails if the batteries were hooked up backwards at some point.

I just did this to my 2014 150 hp Merc. Your video helped a ton! Thank you for putting it out. I ran the testing just as you instructed. No output on alternator. Had to wait a week for a new one to come in. The big dealer in town had one in stock but it was $200 more. Two comments: rotating the alternator into place was pretty difficult. I had to push with my feet against the alternator. When it did rotate, it stopped just a bit past the hole but was easy to line up. The torqueing of the bolts takes more uuumph than I imagined to get the 36 ft lb torque. Tested on completion 13+ bolts. Perfect.

You are the best on CZcams!!! Where you located at? I will love to have you as my boat mechanic

I love your videos🙏🏽 Thanks for all you do💪🏽🫡🛥️

Is this also for a 250 motor or just 300

Absolutely great video! I wish most mechanics were as passionate and thorough as you!! I would only use you if you were in my area!!

God blessing US-4 Marin . 🎉❤😊

I feel like you’re a teacher at heart. Great job.

Awesome!

Awesome Video! The only video I could find that was really helpful. I have a 2015 225 SHO. I think I can do this now. I appreciate everyone's comments. I'll be sure to use PB Blaster first on the bolts.

Hi My mercury optimax 135, even shows 100% oil, it`s beeping 3 times. I know I had to purge couse the oil was goin down to 60% and after I fix it, still beeping. Any solutions?

Great video. Very very helpful.

Really good video much appreciated

Great video, thank you buddy.

WOW!!! This is awesome....Extremely grateful for this video.....could have saved me $3000.00 Thank you!

Can't get a decent alternator on a mercury 150. Mine is a 2020 was pulling 4 amps with everything off, only giving me 10 volts at full throttle. It's fixed now but it was a bad alternator

So shop I work at has a merc 150 4stk In the shop that all 4 of us guys have been discussing. its way over charging up to 15v and toasting alternators. In a matter of a day. New batteries with a new alternator it shows 13.5-.7 BUT by end of few hrs run time its 15-16 volts and a ruined alternator. Any Ideas? merc tech line is not much help. Merc keeps sending alternators its under warranty.

How does an engine just go out of time the belt wasn't broken the teeth were all on it how could it just go out of time

Most of these engines are INTERFERENCE built which means if your cam sprocket comes out of time from the cranks sprocket, valve to piston damage can happen when they contact. NEVER turn the crankshaft clockwise with the belt off and the cam sprockets flopping around like that. You want to line up all the marks BEFORE you let the timing belt loose. If a cam sprocket pops out of position, gently move back to position. But NEVER turn the crank !!! The industry makes sprocket holder tools for such applications.

What kinda fish r them?

Great video, as always. Thank you for your extensive explanation. I am having trouble locating the belt (8m6012373). Is there another compatible belt? Or, do you know where I might purchase one online? Everything I am finding is a different number, or they don't have one for my motor at all. 2019 Mercury V8 4.6L 300hp four stroke.

This video series saved me a bunch of time and money I really appreciate it!

Wow que ricura👍

Omg I can’t watch that lol. Sometimes things go wrong 😂 fishing . But 10 out 10 that fish is in the boat, 1 handed or 2 hands on the galf . I feel bad for the dolphin who got eaten by sharks on way down. Next time lol

De verdad no tengo un Yamaha, pero encontre tus videos por casualidad porque ayer tuve un problema con mi Optimax. Ahora me encuentro mirando estos videos de servicio como un metodo de entretenimiento. Estudio el espanol como un hobby y, como estudiante del idioma, (o aprendiz en este caso), me alegra de que hayas tomado el tiempo para grabar en espanol. Gracias y saludos de Boston

Thanks for sharing in technical aspects watching here in Davao City Philippines

Loved your personality in your video! Your video was very helpful and entertaining to watch 👍🏽👍🏽

Hi - You have a talent for demonstrating and teaching - great work! Thanks and I’m now a new subscriber. I have a 2022 Yamaha f200 four cylinder and the trim has never held the motor up for long. It used to take a day or two for it to drop. Now it drops from half way up to down in half an hour. I took it back to the dealer a few times for the issue to be fixed, and they would tell me it’s fixed, but it never was. Would you have any idea if this is a common thing with new Yamaha outboards, and (if so) which parts do I need to replace? I’m comfortable doing the work myself as it seems the only way to get it done competently. Thanks again for your great style.

Thank you!

Great fix!

Thank you for share your knowledge and expertise. Another excellent video !!!

My 150 Mercury same problem. New alternator just came in and gonna change it today 👍 great video

Good video, explained very well. I have the same unit on my f115. It stopped working, I found a nick in the wire at top of transom height. Water had gotten down the wire and corroded the brush connection (circuit breaker one), yes there is a circuit breaker there. Unfortunately 3 of the bolts snapped trying to undo, so I can verify they are dry, and stainless and alloy don't go well. Currently spraying and let it sit for a while (unit is out), any recommendations with type of spray to seep in and loosen, fortunately the head snapped off and I still have some thread to grip?

super helpful!!! thank you!

THANK YOU! I ordered an alternator for my parents ‘13 150 Fourstroke, but found the problem in minutes because of this. Exactly as you described; no voltage at the alternator terminal and a failed 100A inline fuse. New cable and it’s working great. That ‘13 engine had a different-looking inline fuse, but the failure was identical. The replacement cable is the same as in your video.

manual release valve screw is stripped what should I do?

Por Dios...nunca vi una persona con esa capacidad para explicar y que uno lo entienda sin ninguna duda....maestro una pregunta si decea responderla a veses mi motor no arranca en primero segundo o tercer intento....no pasa cuando lo bajo a la rampa que podra ser por favor...saludos

Muy profesional en su trab..ajo con una explicasion sencilla y clara....y algunos trucos para hacerlo mas fasil

my 150 Mercury is doing the same thing, thanks for the info, very helpful

Nice detailed video. I'm working on a 75 merc right now that is the same powerhead. Merc by yamaha , lol

Peter is the best. Thanks for the knowledge

Merci beaucoup ❤❤❤❤❤❤

Merci beaucoup ❤❤❤❤❤❤❤

Thank you very much ❤

how were you able to electrically test the unit when you had it in the vice on the table? Were you using a 12v battery?

You had a great video series on 450R maintenance that covered supercharger belt but not the alternator belt. I presume replacing the 450R alternator belt is very similar to this video, but what else needs to be removed to do the 450R belt? I.e., does the supercharger belt tensioner need to be removed?
