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 KZfaq and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

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.

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.

@andrevanheerden4936 4 жыл бұрын

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.

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

Thanks again!

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

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...)

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.

@revdcdon970 8 жыл бұрын

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

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.

Now when I start it it stays in foward gear, I have no neutral , what can I do ? Thanks in advance

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 жыл бұрын

+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.

@scotty2307 8 жыл бұрын

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.

Mike Baker No.. the long shaft is connected to the engine directly so it doesn't change rotation.. You want to install the impeller in the direction the engine turns as shown
