As a novice boater, this was an amazingly useful video. Very well explained.

[@1234Jaytay]

Huge help I just started as a parts manager here in Florida in Sarasota and I really appreciate all the videos they're invaluable and more useful than any video I've ever seen on this platform

[@cemyanikk]

I am a marine engineer and I learns too much good knowledges from your channel. Thank you so much.

[@4739-g9c]

Very nice. I finally found a video the actually teaches me something about something. Every other channel is about selling something with only pointing out the obvious.

[@yam9635]

KZbins the place to go

[@DAlilbigman]

Very detailed n thorough! Thanks I love the way you have the areas cut out so I can easily see n understand all working parts. Awesome!

[@allanthomson4639]

thank you - any chance you could consider showing the basic steps+using the "setting plate concept" to setting/inserting the correct shims to take up the pinion+F+R gear for optimum tolerances, good clear explanation - watched from South Africa

[@augustinepora4436]

Clearly explain the lower unit. Awesome

[@johneric3886]

Terrific video. Very informative and simple to understand. Thanks.

[@Leblueskee]

Thank you so much for this. I'm building an electric boat motor and this was so helpful.

[@pawfan]

Thanks for sharing how the lower unit works. I was curious on how it really works.

[@roytaylor3857]

Finally a video that actually makes perfect sense 👌

[@jamesjannell8706]

You guys are awesome. Thx for the education.

[@jamesclark9510]

Awesome demo. Keep up the good work

[@brianl.3047]

I've always been automotive-oriented. My wife and I inherited a 1963 Starcraft a couple years ago with a 1994 Johnson 48 SPL. After a comprehensive online boating class, we became boaters. I'm trying to get up to speed on outboards, particularly in regards to routine maintenance. This video was VERY educational. Outstanding presentation.

[@jimmyadams9257]

Installing new lower unit on a Yamaha 70etlh 1986 having trouble with shifter going in reverse on in forward very quickly. The shifter is in natural and the lower unit is also in natural what am I missing with the reverse problem

This was so helpful! Do it with a Verado someday?

[@SolomoniSadranu]

Thank you for your love of sharing. Questions: any video for install inlet valve and exhaust valve spring valve and rocket arms. Thanks

[@Confidentialcomputing]

Extremely clear. Well done video. Would be good to know variances from freshwater to salt for seals etc given environmental factors for maintenance schedules.

[@johnakagi1088]

Great video that explains the seal points and the maintenance. I would be comfortable replacing the 6 seal point seals on the lower unit. Certainly replacing the water pump. Thanks.

[@alstonshipp9240]

Good explanation!

[@richardatyeo9903]

Very good presentation.

[@EasyBookReviewClub]

Superb video, high quality content, thank you

[@robertmalvarez4582]

AWESOME INFORMATION

[@jarredburns8421]

Awesome video. Very detailed and informative. Thanks.

[@Whisbaby1Vr]

Great video. TryIng to figure out why my Yamaha 4 stroke making a howling noise and bugs out once in gear in the water

[@russellfisher5710]

Great video, so I have replaced the impeller and now when I put it back together I cannot select the forward/reverse neutral properly from the control. I have selected neutral and put the lower unit back together but when I then try and select the gears via the controller it will go from neutral the reverse and back to neutral but not into forward. I did not touch the gear selector when I replaced the impeller and it was all good before the impeller change. It s a good engine in tip top condition and been well maintained and also not thrashed as it was a sailing club engine that a won in a sealed bid auction.

[@danielboltz3635]

Great video!

[@markmurphy137]

Man excellent video thank you sir

[@stevew6141]

Thank you for this informative video! The cut away leg is brilliant👍🏻 It explains visually how a gearbox works and operates I recently bought a boat with very old unknown twin stern drives and twin 1.8 diesel Ford engines- so far I have found that engine 1. Crankshaft turns with prop In drive. engine 2. Crankshaft seized but prop in Neutral and turns! Both stern drive gear levers are stuck so do you think I’m looking at a loss or a project worth investing in? Are stern drives gears easy to unsieze? Thanks in advance for any advice

[@KenH737]

Great explanation of lower unit basics.

[@wofaideal5312]

Very good and well explained wish to work with u

[@Patriottoo2]

Well done, mate!

[@matthewbudlong9813]

[@SalliKenrick]

Very helpful. Does the mercury drive shaft rotate clockwise or counterclockwise

[@willysoriano4196]

good evening Do you have a video explaining how to reinstall trim sender on a Suzuki DT85?

[@cooperstownnyrealestate]

Great explanation thank you!!

[@stevenstreet9754]

Very good information.

[@nicholasm2239]

great video.

[@Jolly-bass-boy]

Brilliant information, my engine wasn’t going forward, just into neutral and reverse, took the gearbox apart n fixed what I thought was the problem but after assembling it back it now goes into neutral and forward but not reverse, I’m starting to think it may be something todo with the shift shaft?

[@Guerrero1187]

I don’t understand how people dislike these informational videos?? Some people just hate their life. I think it’s a great video,keep up the great work and content 👍🏼🙏

[@RobertCowper-f3b]

Could you please show the replacement of the lock plate in the side control for a 2010, 60hp 4 stroke Yamaha. Hoping you can assist ... Bob

[@abrahamu5544]

thank you.

[@jameshalstead237]

NICE JOB WELL SPOKEN

[@TheBluceRee]

Before watching this, I barely knew the word lower unit meant. Now I feel like I could confidently tear a lower unit apart. Also am now able to diagnose many problems.

[@billyphantha]

Very good video, Garrett is a very good teacher.

[@hobiehollister951]

Very informative

[@mrsmd4616]

Any tips on removing middle drive shaft housing thingy on a 9.9. Lower unit came off/apart easy. Seriously siezed together.

[@bentramell729]

Great video but I need help with gear alignment. Just replaced water pump and cant get the drive shaft back up into the power head. Ive put the gear shifter in forward and turned the gear selector on the lower unit to what I think is forward but im not sure

[@makesA.M]

Hi there can you guy's make a video or explain how the gearcase system of clockwise and anti clockwise works,does the gears differ between clockwise and anti clockwise will much appreciate it

[@DT-ob6ce]

I would love to see a breakdown of an '82 Mercury Outboard

[@sgray1906]

Yall are Outstanding !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :)

[@trevortaliana5944]

great video!

[@bouldernelsonbigfoot]

great vid

[@clarencesail]

Really great explanation of the system. Thank you.

[@ryanm2585]

If you were to replace the original damaged gearset with new gearset would you need to re shim?

[@ash.133]

Very very nice 👍👍👍👍👍👍

[@antoniovelasco5675]

Profesional that is all o can say!!!! I have a 2002 Yamaha 225 4 stroke,they replaced the seals twice already and still talking water!it’s worth to keep spending money on it ?or is better just to get a new one…?

[@georgeatallah1926]

Great job very clear video and voice.my Yamaha 115 four stroke 2002 model has a whining noise when travelling about 15-20 kmh noise goes away at higher speeds.otherwise motor runs perfect,can you suggest anything thanks!

[@garyevora8369]

Not really grinding noise but more of a clunking noise when engaged in either forward or reverse. Any diagnosis is appreciated

[@kh2140]

When is there too much slop when engaging forward or reverse?

[@SaltyMechanicsJunior]

GREAT STUFF, MAN. JUST SUBBED 👍

[@markdismang8550]

Some say reverse because it leaves the pin in slope of cam shift. If left in neutral it's necessary to bump start it. ??

[@chrisminer5712]

any idea how a newly installed prop shaft can move in and out by a 1/4 inch after it was replaced?

[@pascualperrino4071]

Hello I’d to know how can I see the difference between a gearbox what rotate to the left and other what rotate to right

[@yellamamba4554]

Is it possible for the forward gear to get worn out before the dog clutch?

[@libingliang7967]

Question, why my prop shaft has a some movement in and out??

[@ImFishHead]

Well done!

[@charlesronk2989]

I have an 2012 Evinrude E75DPLINC. It is clunking in the lower unit when in forward and reverse, but doesn't clunk when in neutral. What would be the likely culprit.
