[@stevenlariosadventures]

Excellent video amigo, I applied the whole walk through you did on my mercury motor. Thank you

[@RFishingtx]

Glad the video helped you out.

[@andrewagius3114]

Very good video my merc dearler put a gauze in side the leg on the water Intake to keep the big stough out

[@spadog63]

Excellent video. This will make the job a lot easier on my Mercury 50 HP.

[@RFishingtx]

@spadog63 Thank you sir! Glad I was able to help.

[@trailtimeszr250]

What an awesome video, i took mine in last year for a 300hr service and it was 585.00 , never again. Thank you❤❤❤

[@RFishingtx]

@@trailtimeszr250 Thank you so much for checking the video out and glad I was able to provide some assistance in saving you some $ in the future.

[@trailtimeszr250]

@@RFishingtxI did the full service minus the impeller this year but the only thing i couldnt do was that inline fuel filter, i have the 40hp. And that filter lives below the bottom coil pac, with zero clearance. The coils and the mounting rail need to be removed to access it. Only you cant access the bottom bolt on the lower pac, and if you did put it back in , it would be a nightmare, it has standoffs behind it,; that the bolts go through.

[@bradramsey9962]

THANK YOU! I just ordered about a $100 of stuff from Amazon to tackle this but it'll save me $500/yr. in having someone else do it.

[@RFishingtx]

Glad to help. 👍🏼

[@VintageEvolutionSkateboards]

As someone that likes to work on stuff ,videos like this help. I'm going to repower my boat with the 60hp and I like to see what I'm facing. Thanks

[@RFishingtx]

Glad to help. 👍🏼

[@lancejones3742]

Good video. I would recommend raising, lowering, and turning the motor after you think the oil has drained out. You will find another 6-8 ounces of oil will drain out.

[@RFishingtx]

@@lancejones3742 Thanks for that! 👍🏼

[@mistrcrvr]

At 25:58 - “It’s got some play, and that’s good.” How much and why is play good? Sorry, this is a Great video but that stood out.

[@RFishingtx]

@mistrcrvr I shouldn’t have used good but should have said normal. It has to do with the hub design on the spitfire props that requires the prop to have a tiny bit of play back and forth.

[@johndovi118]

Lot information, Great video. Thank you. Let us know when you are going to change the impeller.

[@RFishingtx]

@johndovi118 Thanks! I’ll be putting out a video covering the changing of the high pressure in line fuel filter this coming week and later this summer will drop the lower unit and change out the impeller.

[@smokeab4613]

Ive heard there a water pickup filter in the foot. My wanna check that too. I had a evenrude that took a poop on me last week due to a failed thermostat only 50 hrs on the motor destroyed the engine. Just bought a brand new boat with a 6o hp mercury and it will get a thermostat every year.

[@RFishingtx]

Sorry to hear that about your Evenrude.

[@lewhite99]

Great video! You explained everything so easy for us less mechanical people to fully understand. Appreciate you and I did subscribe to see all your future videos

[@RFishingtx]

Thank you so much!

[@mikeford9176]

Excellent!

[@RFishingtx]

@mikeford9176 Appreciate it!

[@mcclaren807]

Excellent video. Good details. Thanks. Only think I noticed was that when installing the fuel filter, you didn't prime it with the primer bulb to check for any leakage.

[@RFishingtx]

@@mcclaren807 thanks for watching. You are correct. I did not prime it in the video and I should have in order to check for leaks.

[@carstx]

Thanks for posting, very informative video.

Thanks! @carstx

[@lostviking540]

Do you have pics/video of where u mounted the vessel view mobile on engine???

[@RFishingtx]

@@lostviking540 I have a video called Tracker Pro 170 Review and Walk Through and at 2:55 on the video I have the cowl off and you can see where I have it installed.

[@lostviking540]

@RFishingtx ok found it. Just got mine mounted and pretty sure I'll b happy w it. Have 408 hrs on my 2017 60hp. Handy to have for sure. I like the voltage reading also it's very helpful. Thanks again!

[@hifivingstarfish6885]

Very good video. I do have a question though. Do you have to change the in inline fuel filter? That one is hard to get to. And if it is not required to change on the annual, then how often is it recommended to change? Thanks in advance.

[@RFishingtx]

@hifivingstarfish6885 I’m glad you brought this up and based on your question, I will put a video out very soon covering this. Although Mercury does not provide clear guidance on the in line fuel filter, it should technically be replaced at the 100 hour or annually whichever comes first. With that said, I would say that a lot of folks (myself included) don’t change them out as often as we should.

[@jokso22]

It says every 300h or 3 years on top of the motor in the beginning of the video

[@skipman4735]

​@@jokso22I changed mine when I did spark plugs around 200 hrs. Easier to do with the coils unbolted.

[@willsmythe]

Great video! One problem: all the links are cut off in the description. I thought it was just because I was viewing on my phone, but they are cut off in my normal web browser too. Can you check them?

[@RFishingtx]

@@willsmythe Thanks! I'm not sure why that happened with the links but they should be usable in a day or so.

[@vincentnieto7792]

Great video! I have a question though. How do you see the hours on your engine? Or do you just everything annually?

[@RFishingtx]

@vincentnieto7792 I have VesselView mobile installed on the engine which shows all the engine data via an app on my iPhone. It’s a must have in my opinion.

[@fratzogmopars]

Great video. When you change the spark plugs do you have a tough time removing the bottom plug? That one is always a killer for me with my Bigfoot.

[@RFishingtx]

Thanks! They definitely didn’t make it easy to get to them.

[@Hubjeep]

1:20 That's a bazaar spec! Both oils cover the same temperature ranges, but are of a very different viscosity! What about 15w-40? LOL

[@RFishingtx]

@Hubjeep You’re absolutely right. Labeled as covering the same temps but one is better for Hot weather ops and one is better at cold weather ops. 🤷‍♂️

[@onthehill7690]

Great vid. Does doing the service yourself void the factory warranty?

[@RFishingtx]

@@onthehill7690 I’m not 100% on this but it’s my understanding that if you keep your receipts and keep a record of the maintenance you performed then your warranty is still good.

[@dwainlsmith]

Did you replace the seals on the upper / breather screws in the lower unit housing? Is it better to remove both of the screws when changing the gear oil? Thanks for such a great video!

[@RFishingtx]

@dwainlsmith Thanks for the kind words. I did not replace any seals on the lower unit screws. When draining the lower unit gear oil, it’s best to remove the bottom screw first and then the top screw which then allows the pressure to release allowing the oil to drain out. In essence you are removing both screws but after the gear oil is pumped back in you replace them one at a time. I hope that answers your question.

[@sidthompson7203]

How did you get the sand out before you put the thermostat back in?

[@RFishingtx]

@@sidthompson7203 Just used a clean moist rag to remove the sand in there.

[@henryrobinson6958]

I was told at BP that don’t use regular zip ties they have them for Marine engines

[@RFishingtx]

@henryrobinson6958 I appreciate the info. I assume you’re referring to the ties I used to attach my vessel view. They have been on there for over 2 years and show no signs of any heat damage. 🤷‍♂️

[@davidvick1078]

Thank you for this video. What kind of grease did you install in the zert fittings?

@@RFishingtx Wow, that was a quick response!! Again thank you for the video. I especially appreciated the information on the thermostat as I was unaware of the maintenance procedure. You have most definitely earned my subscription and I look forward to more videos from you

[@jamesbwell7118]

Why would you not for the gear oil fill it from the top bolt that was removed? So then you wouldn’t have to quickly reattach the bottom bolt.

[@RFishingtx]

You fill from the bottom in order to push the air in there out. If you were to fill from the top, then you wouldn’t get that air out and the lower unit would not be full of oil like it’s supposed to be.

[@jamesbwell7118]

@@RFishingtx Thank you, excellent video!

[@dreamfly555]

do we need to change the oil and filter after the 10 hour break-in time?

[@RFishingtx]

@@dreamfly555 It's a good idea to do so.

[@rma1494]

Should the engine/oil be warm when draining it?

[@RFishingtx]

@rma1494 Not that I’m aware of.

[@captainhidsight]

do u need to change the oil filter every year?

[@RFishingtx]

@captainhidsight every year or 100 hours whichever comes first.

[@kevinwright1152]

Isn’t there a second fuel filter on that motor?

[@RFishingtx]

@kevinwright1152 The maintenance manual only calls for the changing of the low pressure fuel filter. After you brought this question up, I looked to see if there is another filter on maybe the high pressure side but couldn’t find anything. I know the higher horse power motors do have multiple filters but not sure this one does.

[@hifivingstarfish6885]

@@RFishingtx The second fuel filter is below the oil filter and aft about 5 inches. It is coverd by a rubber sleeve and you can't see it unless you pull away the black sleeve. Once you pull the sleeve, you'll see the while fuel filter.

[@Jaquan-y6l]

Can a 50 Yamaha oil filter fit a ho mercury?

[@RFishingtx]

I’m not sure. I have heard they are interchangeable but I’m not certain. If they are and something happened the warranty may be void.

[@tomguy9092]

What about spark plugs

[@RFishingtx]

I checked them but didn’t record video of it. It will be part of my 3 year maintenance video when I change the impeller as well as the spark plugs coming up later this summer.

[@smokeab4613]

It also looks like you missed your high pressure fuel filter
