- How do you service your outboard? Why would you want to?
Well, they all need attention on a regular basis. The motor cuts out, it won't accelerate performance drops, you pick up dirty fuel, a myriad of reasons.
In this weeks Technical Tuesday, i tell you how to quickly and easily strip down your outboard motor , service it and put it back together. The result is that you are back on the water quickly and easily.
PLEASE DO NOT ATTEMPT THIS OVER WATER UNLESS YOU ARE CONFIDENT IN YOUR ABILITY TO NOT DROP BITS OVERBOARD. TAKE IT ASHORE AND FIND A TEST TANK.

Great clip. We watched it twice! Thanks!! Antonio and Kimberly
Great video glad you didn’t drop the screws in the water!!!!
Nice one. Keep them coming. Technical Tuesday is a wealth of information.
The jet you removed is called the main jet. The other round brass piece in the body which you didn't remove is a part of the float assembly and is in fact the seat for the float valve. The second assembly that you took apart with the black rubber diaphragm in it is in fact the engine fuel pump. Glad to help!
Superb Nick, hard to find quality tutorials on this absolutely necessary subject. You did it!
Will save a trip to the shop for me. Substantive and clear, without the classic American bs.
Thanks...
Well done great description of how to do a very important job!!
Thanks for these technical videos with an eye to the live aboard cruiser. Very helpful
Nick. It all the 1000’s of videos out there this was really informative and well put together. I have always just sent them to the shop not realizing how basic it was. One comment, you at least have to cuss at your outboard once or twice just to keep it in line. At least that’s my experience.
Excellent Tech Tuesday Nick.
That was really nicely done and thank you for sharing

Very well explained Nick, thanks and best from HKG
Nice job simple and to the point.
These are good, Nick. Much obliged.
I’ve never seen those T handle screwdrivers before. Gotta get me some of those.
They’re brilliant for extra torque
Several people I know replace the Phillips-head and flat-blade fasteners with Torx-head or Allen-key-drive fasteners on small motors. The Torx are slightly hardened and less likely to strip under-load at that most inconvenient time. I keep a set of gunsmith tips in my tool-kit. The flat-blades are parallel not-beveled so they're less likely to slip or strip-out a flat-blade machine-screw. I also hand-file dedicated flat-blade tips for the jets, file a small shoulder on both ends of the blade to the center goes down into the jet-bore slightly and the blade-tip stays centered in the slot.
Nice and easy! Could give the plug a spiffing up while you're in there Nick.
Good video, now I have my fill of carbs this month.
Very helpful video. Thanks!
Nice job again Nick!
Thanks Nick great video love tech Tuesday
Thanks. I love technical Tuesday. Keep them coming! For those that are afraid loosing a screw. You can use an umbrella/net to put under the water so you catch everything that falls in.
Thanks, nice and simple. Well explained. And to imagine I paid a mechanic $150 the last time...
I don't have a dinghy, and haven't owned a car with a carburetor in over 20 years, so this was a great reminder of how to work on one. Thanks, Nick!
I love these tech Tuesday videos it gives a guy with very little sailing experience see the aspects of your lifestyle that rarely make it through the editing room!! Keep up the good work guys!!
Totally loving these Tech Tuesdays.
After putting all of that hard work on the carb don't forget to take for a Busch beer break!! All work and no play...
Thanks for the Tech Tuesday video. I had to service three small engine carbs last week. Never thought of doing so on a rocking boat but you definitely raised the bar. I fear the plop sound as a screw goes overboard....
Good video, I like your technical ones.
And others, of course !
I have maintained quite a few 2 stroke outboards my family had over the years.
With additional fuel pre-filtering, you almost never have to service the carburetors.
Symptoms you mention in the beginning of your video can well be linked to failing of the fuel pump membrane and clogging of the fuel filter inside the removable fuel tank.
Also, for beginners, a bit more of focus could have been made in disconnecting / reconnecting of the choke lever and the gasket between the air filter / muffler and the carburetor itself.
Great advice for people who are nervous about cleaning carbs. Once again THE best sailing channel in the WORLD 🌍. Keep it up guys
Good advice and nicely done video. Thank you!
Great vid! I would also suggest new water pump impeller and changing of lower unit gear oil at least once per year.
Thank you Nick.
Also, for about ten dollars you can buy a carb overhaul kit for that particular carb. The kit contains a new o ring seal for the float bowl, a new diaphragm for the fuel pump and likely a new valve for the float assy. The vital part is the diaphragm as it vibrates continuously to pump fuel, driven by the pressure pulses from the crankcase. The diaphragm will eventually fray through from the constant motion and then your pump won't pump. Use a bit of silicone grease on the o ring to keep it supple. Save your old but still serviceable parts for spares.
great usefull video.thanks Nick.
thank you - really helpful
Absolute pleasure mate
Thank You SO MUCH for this. Anybody who buys their first outboard should be required to watch this. They should want to anyway when that outboard starts acting up on you and you have to try to find someone who can work on it on Island Time.
Yet another good use for old guitar strings!
Good editing guys. I really like this technical Tuesday feature and looking forward to seeing Nick in the galley, displaying his obvious culinary skills. Best of luck with the Atlantic crossing you two and stay safe and in tune.
Love the mix on your channel. Both the aesthetic side of sailing and the intricansies. Fun to see and fun to learn
Hi Nick If you are buying fuel in exotic locations add about a cup of metho to each 20 lts of fuel to dissipate any water which may have in the fuel you bought.Fuel Doctor or similar is good for keeping the fuel bugs away.
Regards.
David.
Enjoying Tech Tuesdays! I'm furiously trying to catch up to present day. Looking forward to more Tuesdays.
Had to give a like in the commercial. Now I can enjoy the video.
Very much like these tech vid's. Keep em coming .
I'll be crewing on Britican in a few day's. (don't know if you know them?)
Very cute the way you got the outboard to do a cameo as you introduced the subject😎.
Great vid Nick... that thing hauls ass. I'd always be nervous about dropping something in the water.
WOW ! You not just a pretty face. Quick , Concise , to the point . On land so chain saws and lawnmowers etc. Greetings from west of Ireland . enjoy you show very much.
Terysa's back! great news, you work well together. Your world is blue mine is very green.
I now look forward to Tech Tuesday each week!
Main jet M8, I think the pilot jet (idle) is under the plate with two screws... Diaphragm (pump) 4 screw black thingo. We Aussies need to keep and eye on you ;-)
That was another great one. Thanks again! Sk in the UK.
9:48 look how happy that carb is! Well done.
Thanks Nick
Great video and very timely as I just bought our first outboard motor. I hate to be dependent on others for things I can learn to fix myself.
A lot simpler than I always thought. A brave man using fiddly screws over water. Thanks for that. An improvement to this video could be to explain what each of those parts does as I have no idea what the float switch does or the fuel bowl etc etc. I expect fault finding would be easier if I did know. Either way, a great video.
We completed an extreme carb maintenance experience this weekend after patchy performance last summer season. The 10% ethanol fuel not only blocked the carburetor with the typical gunk that needs the cleaning Nick so ably demonstrates in this video, but attracted rather a lot of water to the fuel, which needed changing. -- something worth checking if you still have the sort of issues that Nick mentioned after a carburetor service. We also learned that dealer provided carburetor service kits do not supply the carburetor gaskets, which are easily damaged by normal wear and tear in some models/brands. They are a special order item and peculiar to engine model and manufacture date (in the case of our Suzuki). We are considering a Torqeedo, to avoid back strain/pain rather than maintenance.
Good job, covered the basics. What you showed will fix the outboard problem 99.999% of the time ! Like you said, it is usually dirty fuel or water in the fuel. Will also fix most small gas engines like lawn mowers and the such. Question, on your external gas tank was that a priming pump ? Do you also run an inline fuel filter on that external gas tank line or is there a fuel filter under the engine cover ? P.S. Your pretty handy with your hands. You should have a great career working with those hands ! LOL
Thanks Nick. That was really thoughtful to share this with your viewers. I used to be an mechanic at a marina when I was younger and it sure brought back some memories. PEACE OUT! Ü
Great Tech Tuesday subject. You make it looks like childs play!
Very good even though I am clumsy with 2 left hands it looks easy enough ,think I will put a big plastic sheet around the engine as I know ill drop something :):) Thanks
This is a well done tutorial Nick...a necessary skill for any cruiser. Thanks for another great video :)
Totally enjoy these technical videos.
Nick, I put a small neodymium (rare earth) magnet next to my screwdriver tip when I don't feel like sharing with Poseidon. Check out "baja filter" cheap DIY way to make sure you are putting clean fuel in anything.
Thanks. Good stuff.
Nick , nice video to give folks confidence to tackle a job like this.
We find the modern 4 strokes now have a lot of electronics in them that can trip you up but I think they are getting better components in them now.
I like that 'American tug yacht ' in the background. Cheers Warren.
Another great video thanks. Something to consider, I got tired of taking apart my motorcycle carbs, so I started using Lucas injector cleaner...been years now, use it on motorcycles, tractors, lawn mowers, 2 cycle weed wackers, old English sport cars, been years since I had to clean a carb.
Here's a link to a review...not important, but there's links in it for the product...ua-cam.com/video/TK-dsEKzQsw/v-deo.html
I have been using Stabill Oil Foam to wiinterize my outboard. Do you think it will gunk up the carb?
Movie Maker, I use Stabil fuel stabilizer in a full tank, if not detachable, run it through...shut it down and stow. Then on first full tank Lucas cleaner. Then usually as the seasons change I will do Lucas again. Took 3 carbs apart out of curiosity, & a deeper service, after 1,2, & 3 years of above approach ...all carbs were clean (4 cycle). My plugs run longer & are cleaner too. Happy spring & enjoy your day.
Two things, hardware(nuts, bolts, washers, and hose clamps) are not overly expensive, buy spares. Second, latex or nitrile gloves will allow you to make a salad without a gas smell! Nice work, as alway prevention is the most economical approach.
Excellent!! Cheers👍✌️
great vid ! LIKE TECH TUESDAYS ! I should be fully trained by the time I get my next boat !
Excellent
Good stuff!
Thanks!
Excellent job. Watching you remove screws over the water shows you are more dextrous than most humans. Maybe it has something to do with denistry and practice in not dropping tools down that gaping hole? I always have to provide safety "nets".
Thanks for demystifying that and breaking it down!
Excellent video as per usual! Job well done and much needed. So happy y'all are at it again.
Very useful! #ThanksForSharing
X2 on dropping stuff...I've tied a 'bib' around the powerhead when working on the water, tied a ring magnet with a string, put it in the center of the bib and tied the other end of the string to my tool box. anything dropped would roll to the magnet. 👍 😂👎....maybe.
Great job Nick and in the near future when Ruby rose and Shaggy Sea's get to meet these new kid's need all the advice you can give
Well done Nick, inspiring !
Your so handy!
Great video
very informative
your welcome.... as a "senior" living through your adventures, I enjoy your content~
Thank you Nick that is a very good video, I would not have tried that until now. I was very helpful
Nick,
good tech tuesday!! So do you watch youtube to figure this out, past experience, etc.... How much of your maintenance would you say that you knew when you started sailing or learned along the way?
also watched your live feed and glad to hear that you may be in Annapolis this year? We went back in "15" and plan to go again this year. Keep us posted
Kevin & Rachel
Another great video! Possible future video, how do you go about making sure your rigging tension is not to tight or slack? I’d love it if you ever film yourself doing that. Great day mate!
Sailing Yacht Ruby Rose I’d say right about three quarter to one inch at best. Typical is half to three quarter.
Well done! Thanks for sharing. Have you found that certain outboard motors more problematic/temperamental than others? If so which ones? 😊⛵⛵⛵⛵⛵⛵😊👍👍👍👍👍👍👍👍👍👍
Just did the same thing for my BMW motorcycle! Same tips apply!
Nice job. Loving tech Tuesdays
Well done! Doc!
I wonder if seafoam in the fuel on occasion would prevent the need for regular carb cleaning? I have a small 4 stroke outboard that I hear is prone to carb problems.
Excellent explanation
Mention to look for gasket leaks... keep the tanks clean, if all fails call Ruby Rose..ask for Nick ~
Have you seen many cruisers use a propane fueled outboard? They are suppose to be very clean burning and never clog up. Also I know the gas can put a film on the jets through normal operation, do you ever disconnect the hose run the carb dry before storing the motor on passages to help prevent this ? Great video...
There was a report on one in the latest Cruising Helmsman publication (an Australian Magazine) I reckon obtaining fuel in out the way places could be a real issue. They had a fibreglass gas tank which was interesting (and very expensive)
Good one, and be careful not to drop the bolts and screws overboard 😂
I prefer to take the motor off the rib, and do it on board the boat, just in case a screw drops over the back into the water. Do you ever need to adjust the fuel air mixture screw after cleaning it? I find I have to tweek it slightly to make the engine run smoother
Assuming its similiar to land based 2 strokes, check the plugs when adjusting the mix. You don't want to lean out and burnout your piston.
cool mate
Hmm are you filming/post-processing these to 1080i (interlaced) instead of 1080p (progressive)? Because the output seems to have some amount of annoying scanlines (or maybe it's just me).
Great content though :)
Thankyou :)
On our boat we call the nuts and bolts, happy parts. Everyone laughs when they fall over the side.
Interesting as usual Nick, this seems the right time to ask your opinion about something I was recently discussing with a friend. I believe that more manufacturers should consider using an articulated rudder in their design, it would improve dock maneuverability greatly and I would think be less strain on a auto pilot when on passage. At least that is my basic thought what is your opinion ??
The trailing edge of the rubber can be operated separately from the leading edge of the rudder. What you usually see with an articulated rudder is a secondary wheel inside the main steering wheel that operates the trailing edge of the rudder. The trailing edge can also be used to fine tune the rudder when on a passage or simply left locked into the same angle as the leading edge.
Your right about it being another thing that could go wrong but in reality the only failure would be loss of control of the articulated arm and it would be easy to lock it to the leading edge but it would offer an extra (marginal) rudder if the leading edge failed for any reason. I believe many racing yachts use this system due to it's ability to maintain a heading more accurately and with less strain on steering components. Just a thought - one day I'll raise the beauty of a schooner rig (off the wind) compared to a cutter rig...........
I use magnetic trays from harbor freight, free on coupon, a couple times a year or 3.95 to 9$ . I must have twenty. Also do you ever find screws coming loose? Glad you did the vid
Hi Nick , great video as always ! One request please , can you show how you launch and retrieve your rib and how you sling your engine on as I guess you use a halyard etc . I would also be interested in what size your rib is and how you find stowing it on the foredeck and the pros and cons against having a Rib v inflatable on a 38 ft boat as I’m get my boat med ready and don’t know whether to go inflatable with a 3.5 hp and have the option to stow in a locker , place on snap Davies or foredeck , against a small rib with a larger engine , your thoughts and wisdom please ,Many thanks Darrell
Sailing Yacht Ruby Rose what model have you got the aluminium or GRP hull, starting to look at this option now , thanks for the advice D
Great Nick , but where's "the thing" ??
How do you like that motor? Good video!
that was useful, Nick...thanks!
I'm liking the technical tuesday report. Can't wait to see what's next
I watch a lot of cruising videos and I never see anyone flush out their outboard with fresh water after each use. Do you practice this procedure? I think it's really important after having salt water running through the engine.
