Installing and calibrating an outboard tachometer

[@BrokenRRT]

6 years and still the best video on here for this subject.

[@savagegrizzly7022]

Man I just got a boat for 400$ and I didn’t realize how in over my head I was. Regardless, I decided to give it that good ole college try and I have to say your videos have helped me significantly..

[@chuckgilbert2035]

Great detail. More then I need but see it being valuable to the not so technical people.

[@quieroversipuedo]

Just got a new boat and the tacho is not working, so glad I found this video. I am fully confident I can tackle this after watching your video. Thank you

[@salimsopari]

how you explained the frequency conversion to rpm calculation was great. thanks for another informative video

[@xsbuilder1]

Thanks, I found the math sequence quite helpful. I have installed several tachometers without a frequency meter (didn't have one and wouldn't have known how to use the data before now). When I installed a Sierra tachometer on my BF40, I looked in vain for number of poles info from Honda. I asked the dealer, he said probably 4 poles. The chart from Sierra said 6 poles. In actual trial runs, neither of those gave reasonable RPM numbers. So I used Honda's statement that the engine idles at 800 RPM (this is an early fuel injected engine) as a calibration point. I tried different pole "P" settings on the tach until I got 800 RPM at idle. That setting was 2 poles. With a "2" setting, full throttle and trimmed up, The tach showed 5600 RPM (5500 is rated power) using a 15" pitch 3 blade alum Solas prop. I have used this setting for several years now and I believe it is a good one for this engine and tach. I just wanted to say, there are other ways to get a tach calibrated, though sometimes it's a case of poke and hope.

[@DangarMarine]

I definitely think trying different pole numbers until you get a sensible value is an entirely reasonable way to go. You can't do an damage.

[@1fatlenny]

I know this an old post but I liked it so me commenting should be ok right? I wonder about you connecting the light wire to always be on when your ignition is on. Do you ever boat after dark? Why wouldn't you hook a jumper up to your boat lights so it's only on when you have your lights on?

[@johnnycaulder379]

This is the video that I needed. Shows what to expect when hooking up the meter and what those numbers mean. Thanks!

[@chuckw3217]

Exact same tach on a 1991 70HP 2 cycle Johnson with 12-pole. Have arrow set to 6P and reading on tach at idle is high. I assume I should chose 3-pole and try again. Video is bookmarked for reference so I am hoping come spring time I can get my tach to read correctly. Glad you had this video posted!

[@DangarMarine]

Hi mate. It does seem like a bit of a black art translating the motors poles to the setting on the tacho. Fortunately no harm comes from trying different settings, but you do need to know what the motor is actually doing so you can confirm when it is right. Good luck! :)

[@daneschuck6242]

[@kingfish3066]

Coming at you from Nashville greatly enjoy the show , keep up the great work.

[@Fireship1]

Great video Stu. Missed a bunch of your videos and have some catching up to do! A tach on a boat is incredibly useful. From dialing in your idle rpm to seeing if you are propped at the right pitch. I wouldn’t leave the dock without one.

[@DangarMarine]

Thanks Jack, I've still got to sort out that power problem at the forward control, but other than that I'm loving having it.

[@rocykel]

I've found that apps that listen to the sound of the outboard and tell you the RPM are really good. They could easily be used for initial calibration if the multimeter doesn't have a frequency mode.

[@DangarMarine]

I have experimented with a few some years ago now, I should try a newer one and see if they work better these days.

[@rocykel]

Perhaps I was lucky in that our two-stroke is quite loud. Plenty of noise for the app to grab onto! :D "Acoustic Tachometer" is the name of the app (for Android). Love your videos!

[@sipposbft]

hey stu..great tutorial... and great timing.. my boats tacho has just given up & im in the process of changing...just a question... was recommended a Faria Tacho... they any better/worse than the sierra? Running a 99 mercury 60 thanks again... ok..just noticed the instructions you showed were the faria ... must be the same

[@DangarMarine]

Thanks mate. I'm not sure which brand is better, they are different and marineengine.com sells both of them so I guess they carry both brands for a reason. It may be just personal preference I guess but I would expect there would be a reason to stock both.

[@minAFishing-Channel]

I have a yamaha e60h, he has 3 w points, is that 3/2 = 1.5? It doesn't feel right with the tachometer.

[@marccline7415]

This is how EVERY project seems to go. A solid plan turns into 4 new smaller projects before the first project has been completed.

[@jh61]

Every ten minute project turns into a 2 hour fiasco/....adventures in Dodgeyness. I have 2 boats, So if I do the Math there will a 1/2 hour of actual boating per week....and then it snows in November. So it's mid May now, I might get 5 good hours without tinkering with shit...:)

[@HandfulOfTranquility]

My tach seems to be turned off most of the time, except when I place an electrical load like tilt/trim then it jumps up to an accurate reading. Any idea why? I replaced the voltage regulator (using an off-brand) and at some point re-did wiring under the dash and so either thing could have screwed something up. Maybe the behavior means something to you to point me in the right direction.

[@darrenicon5172]

Great vid. I have a Merc/Tohatsu 50hp 3cyl 2 stroke do you know how many poles it is or what I should set tach on 🤷‍♂️Any help appreciated 🤷‍♂️

[@jonathanmessore1907]

Faria instruments... literally right down the street from my house... world leader in gauges for many years...

[@DangarMarine]

Cool, they do make good stuff!

[@miguelfatman6066]

One additional tip with the centre bit of a hole saw, the drill bit its self has no relief to the flutes so they do not cut the substrate and act as a guide once they have formed the initial hole. A standard drill bit has the flutes reliefs to give a cutting age and these ream the hole as it is cut, if used on thing plate with a hole saw they can oscillate and make the guide hole bigger than it should be then the hole saw will start to wander and give an oversized or oval hole. Always use the correct centre bit for the hole saw 👍👍

[@marklamberton541]

Hey mate, could you do a video on fuel management? Like using a flow meter to get an estimate on fuel usage at different speeds. The only fuel management systems i can find are crazy expensive and over complicated or built into the newer outboard.

[@DangarMarine]

Yes, I'd like to add something like that to the trawler one day.

[@AN-kg4ei]

tach can be calibrated in neutral also with either math or inductive tester right? Is it important to set at WOT? I know it's important to know what output is at WOT but asking specifically about calibration? Awesome video and thank you so much for sharing!

[@johncmoney8394]

I just bought the same tach. Goes to zero when powered, but not indicating any rpm. Checked both the coil and tach signal end with multimeter for positive signal. Adjusted setting on back of tach and still nothing. Is it possible this tach does not work with my old Mercruiser 2.5L I/O?

[@georgespangler1517]

A good tip for useing hole saw drill polit hole and turn bit around and use smooth side of drill bit,, it will keep bit from wondering and making hold oberlong giving you a nice hole

[@excavateboy]

Good vid as well, was waiting for someone to explain how to do this on an outboard without a taco sending unit

[@DangarMarine]

Thanks mate, glad you liked it. :)

[@matts5800]

This may be a silly question, but I'm trying to learn! I've got a 1982 Mercury 40hp. I installed a Mercury tach and the instructions say to set it to 4P for SN 5823918 and up, mine is 6084617, but the tach isn't reading at idle or low rpm, only higher rpms (in the driveway with motor flusher). All the wiring is brand new. Ideas? To calibrate, does the motor need to be under load (e.g. in the water)? Thanks for the videos!

[@benfaber6063]

this is the exact HONDA Instrument. For wireing look about (for example) Honda 135 HP wireing diragram. Good video! Good Guy! tank you for helping the "unknowing People"

[@TimsWorkshopTJY]

Cool, Good video on how these work. I put a long look on mine just for testing rpm back while doing final tune. I want to rig up a short one just from the engine but didn't want to wire it to the wrong leads

[@DangarMarine]

Thanks Tim, they certainly are handy for doing tune ups.

[@TimsWorkshopTJY]

Interesting using Hz on a multimeter and convert to rpm too

[@BigMouth380cal]

I am most likely wrong, but to me while the P= # of poles makes perfect sense, but the C = cycles confuses me. To me, and looking at the back of the Tach, the "C=cyl" leads me to think that "cyl" means cylinders. Any chance this is the case?

[@DangarMarine]

Yep, I think the Cyl is cylinders. When you are hooking up to the charge coil the number of cylinders is irrelevant, but I would say this tacho must be able to be driven off the ignition too in which it would definitely need to know how many sparks makes a single revolution.

[@TheGranR1]

Thanks for the video. I have a question. My multimeter reads the frequency but the signal cable tension is too low. (2VAC) What is the working voltage range of this signal?

Fan of the channel, all the way from Ontario, Canada. I this video is over a year old but I had my father in law ask me to look as to why his RPM gauge and Amp gauge are not working in his 22' Rinker. They were working last year and when he go it on the water this year they were not working. My guess is without having looked at it yet a bad wire but any advice or quick tips on how I might find the problem?? any help would be appreciated

[@DangarMarine]

Unfortunately tracing the wires from the outboard end all the way to the gauges is the only way to find this type of problem. Also check that the outboard is still charging. It could be a problem with the coil or regulator / rectifier.

[@PorkBarrel.]

[@TheAnthony3480]

Dont know what i did wrong hooked up the same way you did and only got 2.9hz on the multimeter didn't change when reved moter or maybe the multimeter iscto cheap its a johnson 3cyl i counted 8 poles plus the charge coil so what would be my pulse count be iam thinking 4 but it reads about 1200 on tachometer and with a laser tachometer it read close to 700rpm so do i need a different tachometer for a 3 cyl

[@hikermansteve]

I just installed a new Faria Tach on my 1989 70 HP Mercury outboard. it does not register any RPM. Will that result occur if the setting is incorrect? Thank you very much

[@416Expedition]

Hey there, great channel great content. Would you know if there is a unit or if it is possible to make a unit that can take all that analog information and convert it into digital? Engine temp and RPM's. I have a 1998 60 HP outboard 2 stroke motor and would like to use my Humminbird unit dash feature. So I would need to somehow convert the analog information to digital and then run it to a NMEA 2000 system then into my Humminbird Unit. Some of my thoughts are, maybe using a Rasberry pie or an Arduino or maybe you might know if there is something out there that already does this?

[@uliloehl]

Hi...how much poles has the Johnson 70HP from 1994? I have a new rpm tacho, and the script for programming ask me to poles and speed ratio... i can set 4 poles to 2 speed r. ,or 6 to 3, or 8 to 4, 10 to 5, 12 to 6. adjustable range at instrument was 1.0 - 360 for programming thx a lot uli

Hey mate! trying to hook mine up now but i have a saltwater series 115 yammy... its a 12 pole but mine only has up to 6 poles same as your guage.. is there anything you can do to make it work correctly without the 12 pole setting? Cheers!

[@rioraton]

Can you use the square wave function on a multi-meter as opposed to Hurtz function to test the tach signal?

[@jw228w]

sorry for silly question, but does the "poles" refer to the number of magnets rotating to create a spark? or something else? thanks john

[@vetterfellow]

I didn't know you could get that kind of information from a tachometer. I thought, you don't shift a boat, but for forward and reverse. Thanks for the Education Stu, I'm going to need to watch this again on those math problems. Got the jest of the installation, Thanks Buddy !!!.

I know I’m about three years late Stu but, I’m planning this install on a Suzuki DT 90 V4 motor that I mounted on my 16.5 ft Smoker Craft replacing a DT55 that was decidedly under powered so, I’m going from three cylinders to four. First, in the early parts of the video you kept referring to charging coils, I think you meant ignition coils? That makes sense to me. The other thing is about the hole saws and drill bits for them. I notice that the bit that comes with the saw has a short part of actual cutter. I also checked on my newer ones and find that the part of the pilot drill that is straight across the blade teeth has no drill flutes. I guess this is to stop the saw wandering and causing the pilot hole to creep, and that’s exactly what happened to me last week when I was cutting a 4” hole in a piece of 1/8” plywood. I ended up with a 1/2” pilot hole and an oval 4” hole 😳😂. Anyway, great video as usual. Cheers.

That doesnt concern me becouse I wired all my gauge power to a toggle switch. What I want to do is either figure out why im not getting power to the tach wiring in my controls, or figure out what wire it goes to on my stator/ charge coil so I can just run a wire straight from the outboard to the signal terminal on the tach. Couldnt find any videos or achematics on line to help. Since you got me through wireing the rest of my boat. i thought maybe you could help me with this.

My Mercury tacho sits on 800 RPM with the battery disconnected. I removed the unit and applied 12V and adjusted the CAL screw to minimum ± 200 RPM but when I removed the power the gauge went back to ± 600 RPM. Please help!

[@skipperskipper2936]

The crank is rpm. The cam determine s the stroke. The ignition fires at same time place of the crank shaft regaurdless of the stroke. Firing on exhaust stroke mesns nothing but on compression stroke it explodes the fuel air mixture making the power stroke. ( 2 sparks but only 1 fire.) This is why u get a false double rpm reading

[@skipperskipper2936]

1 cylinder fires twice. Once on compression and again on exhaust. A 4 cylinder has 2 coils 6 cylinders has 3 coils If u r counting ignition pulses u should keep that in mind. Example: 1 cylinder will count double rpm. Because it is thinking exhaust stroke is compression. So its like compression compresion per 1 rpm. But reads 2 rpm. 300 rpm will read 600 rpm.

Hey Stu, dose poles relate to the number of charge coils on the stator or the number of magnets on the flywheel. Every time I have set up a tach I always need to set different to the number of poles stated in the specs for my motor.

[@ronpowell2373]

DMF351 - Poles = charge coils normally, with 2 poles = 1 charge coil. However I am finding that some tacho signal wires are taking the signal directly before the rectifier, others after the rectifier. I'll let Stu show how that makes a difference on his blackboard, but basically it means you may be over or under by a factor of two . So a 3 pole alternator may need to be set to 3 or maybe 6, with no way to really know until you try it. You wont harm a tacho by supplying too many or too few pulses, you will just get a bad reading. In the one I did last week I had to add a resister (100ohm, .5watt) to the signal wire as the raw alternator pulses were going to 17V (rms for the techies- so about 24v peak) and overloading the tacho signal circuit. The needle was going all over the place . The resister cuts the voltage down to around the 9V rms level and the needle is now pretty smooth in operation.

Cool, followed! I searched you but didn't find it. Im in the Boston area, someday hope to visit your aussie land. Keep on the sweet videos, they are helping my "beyond budget, boating dream come true". Currently running 2x 40HP Evinrudes, going for 3x.... no logical reason other then budget, and fun.

Great video. Poles are in pairs. It's a terminology issue. It's so annoying that they don't provide an oversize backing plate for controls. Saves all that accurate hole cutting.

Looks like you've been gettin some sun!! Nother great vid!

[@DangarMarine]

Thanks mate. I managed to get myself burnt again at the meet up...

Great video ... would you think a temp meter worth it on a four stroke??

[@jimbogasoline2042]

Micheál Cleary Being a 4 stroke shouldn't make a difference. Most motors have an overheat alarm. These motors are water cooled and where I live people are bigger on a water pressure gauge than temp. Our local boat mechanic says " I like looking forward, instead of backwards while driving a boat. So no looking back to see if motor is pissing!

[@DangarMarine]

I think it would be interesting to be able to monitor the block temperature rather than just have an alarm once its already got too hot.

[@TimsWorkshopTJY]

I use a turkey temp gauge. You have to put the prong on the head of the engine

[@stephanemongrain7733]

Me too i think is a good thing to have a temp meter. A temp meter can advice you that your thermostat stay partly open, That make the engine running too cold . A 4 stroke shave to run a the good temperature.............Too cold make engine sometimes not running good, more hard on the fuel and many other short or long therm problems, especialy in cold water........And overheat alarm can't do that.

[@ronpowell2373]

Stu, maybe adding a water pressure switch or gauge would be a good mod for many - use the 'pee' hole fitting in the block to fit a T piece and run it off that?

Hey man I have cuestion what kind of control box work with mercury 50 hp 2 stroke 4 cylinder outboard...can I use or connect any kind of control or i have to use one in specific

[@DangarMarine]

Genernally most forward controls can be used. There are generic wires for ingition, start and alarms that could be cross mapped. Throttle and gear selector cables are standard too, the only thing that could be different is the distance that move to select a gear.
