Easy to follow and thorough step by step tutorials do it yourself (DIY) to help you with your broken lawn and garden equipment including snowblowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like a chainsaw, weed eater, weed wacker, string trimmer, grass trimmer, line trimmer, hedge trimmer, strimmer, brush cutter, leaf blower, or four stroke, four cycle units like a lawnmower, wood splitter, lawn tractor, snowblower, pressure washer, generator or a ride on mower that needs parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.
I have the largest Small Engine Repair Video Library on RU-vid and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!
I want "DON THE SMALL ENGINE DOCTOR" on RU-vid to save you time, frustration and most importantly, MONEY with my HOW-TO videos!

@danabeachy2631 11 месяцев назад

The best impeller replacement video on tube tube hands down. You cover everything start to finish in a timely matter. Good job Thank you

@WindrifterMr 6 лет назад

I am a retired mechanic myself and I really like the fact that you do such a great job, (as far as good camera angles, great explanations, and details) which are lacking in many other videos. Keep up the good work.

@SgtDodd 5 лет назад

Thank you young man. My 1973, 7.5 stopped spitting water. At 67 I'd usually pay someone for that. The hardest part was fitting the lower unit back on. Found that standing motor on the cover worked.

@andymain8716 Год назад

Another great video, thanks Donyboy. My motor is almost identical to this, probably a bit older, and it would have be a real pain of a job to do without having watched this. The zip-tie trick didn't work for me so I cut a ring of 1 inch flex hose, bent the impeller inside of it and then mated it up to the housing so I could just push it down and this worked great.

@wbgator1 8 лет назад

Nice job once again. Good old Mercury..... and looks like it hasn't seen any hard use. I did jobs on them like this. Where I live we call the impeller the water pump. Also, I use a little dish liquid to lubricate the parts when doing this job. It helps the pump get its initial few turns off to a nice slippery start and then the water just washes it away. We also called the fin above the prop the cavitation plate. Thanks, haven't done one of those in a long while, brought back old memories. Keep them coming

@tonym6920 8 лет назад

Hey Dony, great video! You know Dony, I don't own a boat, but I find videos like this fascinating in that I always learn something new or just to see how things work. They're great learning tools and afford the rest of us DIY'ers a chance to broaden our knowledge and gain confidence when we're confronted with a repair that, at first, seems way over our head. Thanks again!

@andrevanheerden4936 4 года назад

Hey Don, great video it is but three steps l would recommend. One: grease the splines of the shafts with water proof grease and slightly lube the little o-ring on top of the driveshaft. Two: when installing the g/box rotate the fly wheel at top of engine very slightly clockwise or rock it back and forth to line up the splines. It will slide in easily.

@mattymiller3789 5 лет назад

thankyou so much for this very detailed and lucid video! Got a new boat with this motor and was trying to diagnose the problem of stating and stopping, finaly realised no water from hose as i am a land mechanic... ran half a dozen times for 5 minutes. going to see if any damage after changing the impeller! 10/10 video mate

Great job ! I have a 1990 Yamaha 9.9 low hour motor that has never had a new impeller and this is something I have been wanting to do for months! Will do this sometime this week since we are quarantined! Parts for that old of a Yamaha is what I am worried about finding. Excellent work. Thanks again Donyboy!

@buff985 5 лет назад

You sir saved me a lot of time and money. Thank you so much. Tip for everyone watching. If it doesn't go into both gears obviously something moved in the process. Once you get the drive shaft back in put both nuts on finger tight and try and make sure it goes into all 3 spots (forward neutral and reverse). If it doesn't loosen the nuts and pull the shaft out just slightly so that the gears aren't changing and adjust the shifter. Before tightening the whole way down spin the prop and make sure the shifter is in neutral. That way you won't have to go through the whole process again. If it's wrong you'll start the motor in gear (don't ask me how I know...)

@joshhartelt7022 3 года назад

I too found that out but upon trying to remove the lower end again and it's stuck, opens up about 1/4" but that's it. Any ideas?

@davidpatterson5728 2 года назад

Of all the videos I watched, there was none that mentioned the copper tube. Yours my friend saved my butt! I removed mine and there was a piece of the old impeller lodged in he impeller end. Had I not seen your video I would have NEVER looked at that tube. THANK YOU!! Your videos are head and shoulders above others. I am wondering however, should there be a sealant between the lower and upper half when putting it back together? When removing the two halfs there was a clear silicone substance I had to scrape off. I did put a small bead between the two when reinstalled. Thank you so very much

@fleetwin1 8 лет назад

Rotating the flywheel slightly while installing the gearcase helps to line up the driveshaft splines, and don't forget to lube those driveshaft splines before installation!

@revdcdon970 8 лет назад

Great vid, as usual. I just helped do this to a larger Mercury (150hp)and they are very similar. A couple of things I found out. It's best to start by placing the gear shifter in gear (we used Forward). The reason for being in gear is the prop can be moved so that the splines at the top of the shaft can be aligned to slide the lower unit unto place. The nut that can not be taken off until the lower unit is broken loose is actually to help hold the lower unit from falling out and getting damaged, while starting or removing the other nut(s). On the larger engine there was a sleeve to align the water line and the shifter had to be coaxed into place as we tightened the unit holding nut in the front. Piece-A-cake it wasn't, but after we learned the method of this madness, it became more straight forward, and now that I may never need to do it again, I felt proud that I can. Hope this may help someone else to shorten their learning curve. Thanks for the Movie Don. blessings, rev don

Nice water sleeve to fit in pump and over the brass water pipe leading up. Wonder if those are a standard part or heat resistant plastic from a hardwear stow.

@Dinkymaster7 8 лет назад

I've done this thousands of times on these 9.8 mercs. And yes, you are right, it's really a pain to get the lower unit on as well as having the key lined up. That looks like a good motor you have there, take good care of it!

@googleplusisdead 8 лет назад

Another great video, thanks! Wow, Merc sure is easier than my old Evinrude, takes 6 bolts to remove lower unit, and then you have to remove the shifter connector, a real pain and often stripped by folks since it's just brass. And reconnecting that is a whole trick in itself as well. However, having two very similar impellers for the engine is a bit weird, glad you pointed that out. I'm assuming you could have just checked the shaft itself vs. the inside diameter of the impeller. Lastly, I'm surprised you could blow air through the top with the thermostat in there.

Nice vid! Didn't get mine installed unfortunately.. tried for over 2 hours to get the impeller fitted but just couldn't get it in and over the key really annoying job to do. To make it even worse the old impellor was working and looking fine, thought to do some preventive maintenance. Ended op with no cooling at all haha. Will try another time to get it fixed.

@scotty2307 8 лет назад

Great video donnyboy. A couple of tips if I may. Start with the shift lever in forward gear. This will let you turn the prop to line up the drive shaft splines when you are re installing the gear case. And also, apply some grease to the drive shaft splines. This step can save you from absolute misery, next time you have to remove the gear case, especially if you run in salt water. It is certainly nice having the flat on the shift shaft. Some outboards do not have that. It is no fun to get the thing back together only to find that the shift lever wont move. LOL I don't know what it is about those older two cycle outboards, but if you take care of them, your grand kids will still be using them down the line.

@furyiiiplate 8 лет назад

My Merc 9.9hp 2 Stroke impeller only has about 10 hours on it, but I was just thinking my Mercury Classic 50 has a heck of a lot more hours on it and should be changed.... Then your video shows up and I think that is the Final Hint!! Now I remember how easy it is to do... Thanks!

@scotty2307 8 лет назад

+furyIIIplate Keep in mind that, when it comes to rubber impellers, it is all about how long they have been on the unit, not about the hours of run time. If a brand new impeller is installed, and then sits for 3 or 4 years, it would be risking your engine to run with that impeller.

@googleplusisdead 8 лет назад

YES, change it NOW! I ruined my 15hp by thinking it was peeing "enough". It was, 'til it quit, then engine overheated and now no compression... :(

@scotty2307 8 лет назад

Gogle Plus Sucks I am sad to hear that GPS. This is, unfortunately, not uncommon. When one piece comes of an impeller blade, it often takes the rest with it. It can happen almost instantly. Usually, the first indication noticed by the user is the engine quitting. Most manufacturers specify every two to three years, for water pump service. That means, if you install it, and then let it sit for three years, replace it again before you use it.

@lindabushey3524 4 года назад

Fantastic video! Really enjoyed it! It inspired me to work on my 1985 Mercury 9.8 . Things went very well except for I have no reverse and neutral is in the reverse position . How do I go about getting reverse, neutral and forward working? I read others had the same issue. I would appreciate it if you could add some guidance. Have a great day!

@302vettelife2 8 лет назад

To say they don't always come off that easily is an understatement!

@petersaupe7455 4 года назад

I always lube the impeller and o rings when I install the new impeller as most wear is caused by dry start ups.I also pull the motor over without ignition on so as to prime the water system on every start up when the system has had a chance to drain down.
