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.

THANK YOU..I've been using this same motor since New ..in Salt water.always flush it out with fresh.. Still runs...I've been wanting this simple info for Year's!! THANKS AGAIN

[@Med1na2012]

Wow this is a good motor! Found one buried 2 meters under the sand on the coast Took it apart cleaned it and it runs like new!

[@aurozappa305]

What really lol

[@RentersHomestead]

Thanks, I have watched many of your vids and they are all great! I would live to see more outboard stuff. Thanks for your channel.

[@CraigArndt]

Evinrudes are good motors, used many of them on fishing trips up in Britt Ontario.

[@JPilot2]

Good job! The 8HP Evinrude is a marvelous engine! :-)

[@donyboy73]

a good youtuber to ask that question is classicoutboards

[@geetarnut]

Hi, the front screw is LOW SPEED fuel! Start by turning in fully! DON'T TIGHTEN! Simply turn it 2 full turns out!, counting the turns, start the motor. Then, slowly, turn it while running only a quarter turn each time, OUTWARD. Wait 2 minutes for motor to catch up in rpm! This tells if fuel delivery's rich enough! When rpm stays the same, you turn the screw INWARDS, again, at 1/4 turns,, until rpm increases noticeably, and if the motor starts to cough, turn the screw out until it smooths out!

[@leeowens6654]

Thanks alot you guys rock

[@claytonmorris5352]

I had a 1986 8hp Johnson. Love the primer . 4.5 hours wide open on a 5 gal tank

[@SeahawkSailor]

Thanks! Just aquired one of these, and this will sure help

[@donyboy73]

good tips, thank you

[@robertpayton3795]

Thanks for very informative presentation.

[@-He-Man-]

Why doesn't my engine stay idling when it's running? Thanks for the video.

[@Marky_Muk]

Thanks

[@carlmartin8704]

Thank you

[@ryanptimleck]

Hello. If there are no marks on the tiller how do I know where to position the throttle?

[@HK0HunterKiller]

I'm a bit confused. You talked about the primer, but isn't that the choke? Or does it have both names?

[@JwormJ]

Where can I get that cover? My 87 8 hp Johnson [looks like same motor] needs a replacement.

[@donyboy73]

it wouldn't be good for it, but on these you have to throttle down to shift it

[@RobbyWorld1]

Nice job. Thanks for posting.

[@fleetwin1]

Thank YOU for all your great videos!

[@millertimeatthelake]

I have the exact motor as yours, what are the part numbers for the replacement carborator top cover and fuel bowl...can't get it to idle smooth, stalls and studders when full throttle like it's starving for fuel any help would be appreciated

[@fleetwin1]

This engine is quite difficult to sync up properly (according to specs). The first step is to set the idle timing, there is an timing stop on the port side under the flywheel. The idle cracking screw does help set idle speed also, but the cam pick up screw must be backed out first. The cam pick up is set after idle speed/mixture is set. The air box and gasket must be properly installed, or the engine will run lean at WOT. Like I said, an overly complicated process indeed!

[@chadhall9606]

Have similar motor tan fine 2 times I ran it went to start when leaving would hardly start when it did could not give it gas would just die

[@aaronbarton9811]

Do you have the part numbers for those parts

[@dmcginnis1934]

I have a 6hp looks identical. It has the old carb top piece with the adjusting screw in the front. Is the air fuel adjustment the same for the 6 hp too? 4 to 5 turns

[@wynkibabb1648]

Hi, clear and to the point. great job on the video. How about links for those parts.

[@edgarm9522]

I have the same motor, and I'm trying to figure out how to remove the breather box, any suggestions?

[@brandonvanhorn4729]

Theres a good video out there an 8hp evinrude break down

[@donyboy73]

yes it's the lawnmower graveyard, lol

[@donyboy73]

on this motor it's a primer

[@Outboard1boats]

I'm having the same problem with the primer it only runs when it's pushed out how did you fix it

[@tommylambert8027]

Evinrude and Johnson are like a Cummins diesel motor they keep running

[@shanejtbusinessaccount5949]

Where did you get all your parts?

[@nismo2ful]

And also how do i set the trottle a litle higher cause when is in neutral it shuts off. And some times takes couple of times to start thank you for your help

[@donyboy73]

unfortunately i don't have any

[@fredhuang9223]

Hi Donny, there is no high speed needle adjustment on these correct? Mine idles great but almost dies when throttling up.... carb is super clean and rebuilt. Why?

[@1997cr80r]

I have a. 1968 6hp that's really clean

[@561arcadia]

Good video....how do you take off the lower unit on that... I have the same motor and I need to change the water pump

[@donyboy73]

just an air box, no actual filter

[@nickdillon91]

hey dony i have just inherited my grandfathers 1982 4 hp evinrude and was wondering what the lean/rich button purpose is and how i would use it

[@klikerklik8872]

Greetings!!! tell me why there is no water from the hole in the exhaust ??? Motor 5 HP evinrud 1996 .What to look for???

[@nikolahrustek21]

great video, as always!!!

[@GmGarlo]

my 9.9 evinrude will start with choke but will stop right after what should i troubleshoot for this problem .you always give great advice HELP

[@epic49ersfan]

It took me spraying every hole with carburetor cleaning fluid. A hole was plugged and did not allow the righr mixture of air n fuel. Also make sure fuel is going through.

[@epic49ersfan]

epic49ersfan actually mess with knob mixture first them do what I said.

[@GmGarlo]

epic49ersfan Thanks epic 49 , I used about half a can of carb cleaner on the old girl and i took note to clean every hole really well and it started right up and purring like a kitten . Thanks man , I AM GOING FISHING!!!

[@florintancu9352]

Hey guys! I have one Evinrude 6hp,exactly like this model,i checked to see the fabrication year,i found something like 1993 on Evinrude official site but i m not so sure about...so can someone help me telling what year Evinrude Company fabricated this kind of engine? Thank u!!!

[@ristomattikolsi5711]

I noticed that green push mower back there with white 3hp Briggs engine on it. Is it "fixheruper" or is it just for spare parts?

[@donyboy73]

a marina or on ebay

[@robertshields683]

My 8 h.p inside would run but not idle, took the carb off found the small rubber tube in the float bowl rotten off , replaced the rubber tube, now runs like new. Would only run originally with primer pulled open partially

[@BoughtNotBuilt]

Looks like it was a well kept engine. Are you going to put it on a small boat?

[@BoughtNotBuilt]

Oh well still a great video. Keep it up!

[@ncwarrior62]

Hello Sir I have a question about the 8hp in the video. My original top plate the old style broke where the roller attaches with a screw. If I order a new plate what modifications are required? Are there new flat gaskets for the channels? Thank you

[@seanbarber6945]

Have a 6 HP looks just like this one

[@stephanlokkee]

hi great video..i have the same engine and it comsumes a lot of fuel..i checked the air screw today and it was completely shut...do you think it is that the problem..i turned it 3vturn anticlockwise

[@gatrwrksMarshall]

Does this outboard need an air filter?

[@nismo2ful]

Hey dony I have a 50 hp mercury boat I wonder if is normal that when. I start and keep in neutral i drip gas from the two carbs but if I push ,to full trottle does not drip

[@danielsvensson356]

Have you worked on a Evinrude yachtwin 3hp 1968?I have one. It starts but it just runs for a few seconds.I will see if i can get it to run. Good videos! Thanks.

[@jair8890]

Where did you buy the carb Parts? I need them too

[@dontrob1553]

how to replace the starter rope on 1988 evinrude

[@siemenstraffic]

Is there any Briggs OHV engines in the graveyard that you want to part out?

[@ObbiShade]

So whats your idle rpm? It runs so smoothly :O Mine 6 hp evinrude is smoking sooo much and i dont know why :/

[@krzysztofebertowski8629]

Hi, do you know where I can find a specification or what's the name of this Evinrude outboard motor ?

[@darrellmorgan4041]

What year is the motor

[@deanteasdale6252]

I need to rebuild my carb on the same engine and am leary of the pull rope assembly can you comment on the correct way to remove it? Thanks, Dean

[@KeepinYouUp07]

He has a great video on that! Helped me do mine.

[@raaron]

What are the torque specs for the gear case bolts?

[@yvesf5355]

Hi Do is this a 1988 ? and what is the proper Gas mix mine say's 100/1 thanks love your videos .

[@donyboy73]

i would go 50:1

[@seahawks75]

how do you mix the oil

[@dovydasjackevicius4736]

Idk what is up but my motor has been sitting for a year and for me to start it I have to spray carb cleaner into the air box do you know what it could be?

[@Squatch69]

Take the air box off

[@antonmihai8231]

Hi, I have an identical engine. I'm having trouble starting to cold. I also changed the piston rings, the spark plugs, I cleaned its carburetor and it still doesn't start. It starts very very hard with the shock pulled and the acceleration at maximum. After starting for the first time this way the following starts are very easy. Can you advise me what to do? Thank you.

[@nathanmcolton]

Check the crankcase vacuum. If there's a crankcase leak, it will need new crankshaft seals.

[@Outboard1boats]

Is there a way you can send me the model number of that motor I have the same one but no model numbers

[@donyboy73]

it was a customer's so I don't have it anymore

[@patrickmiko6748]

Does the motor have to be running to switch in forward and reverse?

[@AndreeewP]

A little late but the motor doesn’t need to be running to move it in and out of gear

[@edwardhill6945]

YES. The service manuals state, “do not force the shift lever when the motor is not running”. If you need to do it, & the lever won’t shift easily, turn the flywheel while moving the lever…but do not force it.

[@tomwrona1973]

Check timing some designer missed ,hen grind stop to correct some models cant plane boat because of this , I know I worked there 30 years

[@matthewowen538]

Hey mate just wanted to ask a question how many turns on the front screw for the fuel mixture as mine will only run with the primer partly out

[@donyboy73]

I don't remember but try 2 turns out as a starting point

[@zx8401ztv]

Smashing :-)

[@FrenchValleyAirport]

Can anything happen if your going full throttle and put it in reverse? Or vise versa?

[@edwardhill6945]

Only an idiot would do that.

[@NLINE7]

That little piece of plastic on top of the carburetor is one expensive little piece of plastic. I just bought a 1990 Johnson 15 hp and it has the plastic top on carburetor that was cracked. If I'm seeing it right the plastic part and carb kit are going to run me around $125.00 U.S.

[@stevejancornwell5578]

I have an '87 Evinrude 8hp similar to this but there's an idle adjustment dial on the front of it. Any idea if the tuning sequence or adjustment screw placement is the same? Idles and runs slow-medium speed fine but high speed seems inhibited.

[@fredhuang9223]

Did you ever fix your high speed?

[@stevejancornwell5578]

@@fredhuang9223 No. We have that slow speed idle adjustment knob on the outside front, but aren't quite sure which inside screw(s) control the high speed. It's still in winter storage so I can't take pics for you.

[@GmGarlo]

hey donyboy, i got the same motor , what fuel ratio would you put for that engine because i am mixing a 50/1 ratio and i find it smokes too much, what ratio do you put ,THANKS and GREAT STUFF!!!!!

[@timandmichellelefever1877]

I have this motor and the manual. It says to run it at 100 to 1.

[@JayandRig]

@@timandmichellelefever1877 I have been running 50:1 with varying performance. How does it run at 100:1?

[@SkinE-Vadee-Veechee]

Do you run it with 100:1 fuel ratio?

[@edwardhill6945]

No, do not do that! Under pressure from EPA, the manufacturers stated to run 100:1. There was a sticker showing 100:1 beside the fuel line connection. That lasted for only 3 years, until they started cooking engines. The recall consisted of removing the original sticker & replacing it with one showing 50:1

[@SkinE-Vadee-Veechee]

Ok got it. Mine is an 88 and says 100:1 so I looked it up and heard that same response from other boaters. 👍

[@donyboy73]

actually it's not my engine

[@inspiringengineer]

What it it's all smelly and farty, would that mean it's an 'evenruder'! lol ;)

[@hp11208]

1st

[@pontiachotshot]

why do they have to make boat motors so complicated ? why not just use a 4 stroke 7HP briggs motor with a 4 speed tranny ? i understand that 2 stokes like to rev but if you put a 4 speed gear box behind that 4 stroke, it would be just as good.

[@edwardhill6945]

The complexity of a 4 speed gearbox, along with the cost just wouldn’t be economical. Further , the motor would weigh 100lbs, & the noise of a Briggs would be unacceptable.

[@fleetwin1]

Well, admittedly this is one of the most "over designed" engines we ever produced at OMC...All the silly adjustments just add confusion, and don't make it run any better than the simpler metal carbs... In any event, The spring loaded screw is the throttle cracking screw. And it surely does have an effect on the idle speed, but the idle speed is set by setting the idle timing with a slotted stop on the port side of the engine. This engine will NOT run properly at high speed without the airbox..

[@lakelandstacy836]
