2008 Suzuki 2.5hp Full and detailed service and run- {Everything you need to know}

This is a full step by step service including impeller, spark plugs, engine oil and gear oil. It was going to be for sale but now - this stays with me!

[@michaelsimpson9779]

Just a quick tip when applying grease to bolts. If the bolt is going into a blind hole, you dont want any blobs of grease on the end of the bolt. The grease may well fill the hole and hydraulically lock the bolt which could result in damage trying to get it all the way home.

[@dp47280]

Good tip. Thanks.

[@NtwoOo]

What an awesome little gem you produced! My son just got this very same motor for his birthday. This video will help him tremendously when we start wrenching.

[@dp47280]

Happy Birthday to your son - hope the video helps

[@mariobuttigieg1209]

Excellent step-by-step vid, especially for the novice

[@dp47280]

Mario Buttigieg thank you. It good to have the feedback.

[@chrismabry1657]

Excellent video. I used it to replace my impeller on my water pump. The only problem is you skipped over the hardest part of assembly, lining up the pick up tube for the water pump. I used a solid wire to line it up since I do not have fingers that are skinny. Thank you.

[@ricdanger2]

100% the hardest bit…

[@anotherangleUK]

Good video, I have one of these little outboards that I use as an auxiliary on my boat. Good service work through.

[@contendersegler]

like this video. As an alternative to the gear oil pump I use a 30ml syringe with a plastic adaptor - 5min on the lathe and no cost... and: it might be a good idea to remove the tank and flush it; mine had collected some stuff over 8 years....

[@dp47280]

Thanks for commenting. Think I will flush the tank too. Makes sense!!!

[@chaimsalamon]

Do not put grease on all bolts. Previous comments are correct. Could result in problems/damage. Do not put a new spark plug into a sooty, blackened hole. Use pipe cleaners or any non abrasive medium to clean out the burned material.

[@jeffreygenn5050]

Thanks, I just got a good second hand one and will follow your servicing before I use it 👌

[@briangilliland3620]

This is a brilliant video - thanks. The right amount of FOMO, clear commentary, dubbed when necessary in to avoid background noise., and no unnecessary "continuity music", It has to be one of the best I've seen - certainly helped me effortlessly and without stress, service my 2008 Suzie 2.5. The only query I have - yours has a good tell tale flow, mine has only the 2 fluffy jets and no main telltail. This apparently is quite normal on some models (stripped down chart says that the tube isn't applicable to this model???). Any comments on that pls?

[@dp47280]

It’s good to hear that you liked this video. Regarding the lacking main jet- if it doesn’t have it then there’s no need to worry. I imagine the ‘fluffy jets you mention are the exhaust and as long as there is bits of water coming out then I would suggest you have circulation. Is the main jet definitely not there? Sometimes salt water crystallises and blocks it? Otherwise regular maintenance of the impeller should give piece of mind.

[@gerardcollins1767]

@@dp47280 how to check valve clearance,no one mentions this not even in handbook which is a joke.

[@dp47280]

@gerard Collins I’ve never heard of anyone bothering with valve clearances on these motors. Certainly if they were ever out it would involve shims I imagine and I would be surprised if these are even available.

[@contendersegler]

@@gerardcollins1767 hi, if you remove the motor cover you should find a label on the starter body (facing aft) saying : "valve clearance 0,13 - 0,17mm in and out "

Great video ! I just bought the exact 2008 model engine used last week . When I try to put it to gear it makes a noise and it doesn’t get engage to gear . Also it doesn’t have water comes from back side when its running .

[@dp47280]

This sounds like there is something sinister going on. I suspect that someone tried to do an impeller change and they have assembled it incorrectly. If so it’s an easy fix to make sure the shift linkage and water tube are located properly. Good luck

[@phishermonjon]

@@dp47280 hey I just got the exact motor too 2008 model. But try to figure out this dosey of a problem, mine doesn't have water coming out the back side either but get this their is no hole for it too close me out of! Where the hole and plastic bit should be is factory sealed! I'm going to take it apart to find out what's going on here, let me know please if you have any ideas?

[@t7j]

Hi, hope you see this even thought this video is 4 years old. I don't know how many hours I have driven mine, but not that many, I got mine last year. So I wonder if I follow your video, is that enough or do I have to go to a marine shop because there is some thing I can do, but not all so it has to go in for service?

[@briangilliland3620]

Any clever tips on rejoining the bottom of the water tube to the pump when raising the gearbox back to the leg? It is hanging up within the leg and seems randomly placed. Thanks

[@dp47280]

Yes...... I use long forceps and some marine grease around the ‘mating surfaces’ to ensure correct Alignment. A gently twist can some times help to get the drive shaft located as well. Hopefully it helps.

[@mio-ww6dw]

I used a thin steel wire loop around the tube to direct it into its fitting and a cell phone light to look into the gap while doing it

[@alparszabo]

Hi just one thing i want to ask. What about gresing the neck where it turns? Mine is making a litle bit of noise and i cant find out how to greas it and when i move the engine it looks like it has just a litle bit of play too like its mowing up and down is that a problem? Or is it normal? Thankyou!😊

[@benjaminsher7774]

Thank you for video - could you guide me to a kit for 200 hour maintenance for this motor? I want to do a full tune up but don’t have a clue where to source the parts (in USA)

[@dp47280]

i cant give a full 200 hour kit guide but on these motors it isn't expensive to just change everything - remember the thermostat. Mines just gone

[@lovetheprophets]

Thanks for the great video. What’s your take on oil engine and gear gasket? In the manual it says we must change the gasket whenever we change the engine oil.

[@dp47280]

do you mean the gasket on the drain plug? If so I tend to work on the principle of change if it drips. If you have one to hand change it. If not don't lose sleep over it- just put the old one back on after cleaning it.

[@drodss]

Great video. I have the same year or so I believe and the water outlet only comes out of exhaust. There is no spot I could locate. Just wondering if one of us is incorrect on the year? I have read that model like mine has issues with overheating at full throttle due to poor design with no water outlet. Thank you.

[@dp47280]

Dan Rodriguez Thanks, mine has the year printed on the plate. Mine also spits water at the exhaust too but has the pee stream as well. Has yours definitely got no pee outlet. I know earlier outboards (thinking mariners) used to block with salt crystals quite easily. It does seem to be a cheaply made outboard in my opinion. I still have it though as it’s so handy and light.

[@drodss]

@@dp47280 no mine definitely does not have the pee stream. Here is the s/n if you can help me out. 00251F-887761 .I drove myself crazy looking for a pee port...lol. thanks again.

I've got the 6 hp. I wanted to know if 19oz. Is the amount of oil it takes.

[@NMG3]

Do you know information about valve clearance? Engine hot or cold? How much is valve clearance ? Thank you. Nik from Greece.

[@dp47280]

Sorry, I've never had reason to bother with that.

[@dgalvan529]

Thanks for the video bud just subscribed! Had a question... I just bought a brand new outboard same as yours and there was some oil in one of the drain holes on the lower unit where the water pump is. I was going the break in and noticed some oil coming out of the drain hole and turned it off. I opened it up and cleaned it and it looks to be good now. Is it possible that if the motor was shipped upside down gear oil got in there from the hole in front of the water pump where the shaft goes?

[@dp47280]

It’s always possible but I would have assumed unlikely. A little hard to diagnose without seeing it. The seal shouldn’t leak at all. Have you had the gearbox off already then? Just thinking if it’s brand new are we thinking of the same thing?

[@dgalvan529]

BeMoreBear it was brand new hadn’t taken anything apart. When I noticed the oil I turned it off. The oil was in the weeping hole right next to where the water pump is located. I sent it into a dealer to get seen but that won’t be till about a month and a half they said. If you email me I can send you a pic. [e-mail] thanks bud!

[@ceridavies8906]

Hi, I’ve just bought a 2008 model as an aux, but mine hasn’t got the water tell tale nozzle and no water coming out, I looked up the serial number and it is a 2008. Just wondering is yours definitely a 2008?

[@dp47280]

Hi, Definitely a 2008. All water cooled engines should have a tell tail of some sort.

[@mymonster156]

What about the fuel filter? These engines usually don't have one!

[@dp47280]

no oil or fuel filter

[@mymonster156]

A major issue! You must install a filter before the Carburetor... A 50 cent filter will work.

[@kr.3563]

How do I check the compression? When I do it just says 45psi. Though it runs properly and has power. What do I do wrong?

[@dp47280]

I think you should be between 140psi and 200psi. You may struggle getting the top end pulling the cord though. 140 should be achievable.

[@ambroulard]

I have one Question,, when you buy an outboard like this from Suzuki NEW does it already have gear oil in it or do you add that after purchase?? It seems like it would come with it in since its a sealed system but what do I know. Thanks!

[@dp47280]

The gear oil should be pre filled but the engine oil will have to be added when you buy the motor. I think that's the same across all brands but double check when you buy you motor. Its easy to fill in any case.

[@sandorlascsik5462]

[@garyboyce6186]

Hopefully this video is still active, just a question on storing this motor off dinghy and in the boat after use. Which side do you lay it down or does it matter? Thank you

[@dp47280]

yes it does matter. It normally has a sticker telling you 'this side up' on it. Pretty sure mine is handle side down. when its in the garage I stand it up though as I don't want it to get scratched!!. Hope that helps.

[@stephenburnage7687]

The preferred storage is vertical but if you need to store horizontally, store handle side down.

[@vrva3138]

I recently bought a DF2.5 (2020 model) 20" Shaft motor and It works perfectly fine except, when I try to steer at quarter to half throttle, the steering becomes stiff. So every time I have to turn, I have to bring the motor to a complete idle and then steer. The steering tension adjusting knob is set to loose. any advice on this is much appreciated. I have seen the same problem reported by another person in suzuki outboard forums and no one so far has been replied.

[@dp47280]

I can’t say for sure- 20”? Is that a long shaft? And is the boat designed for a long shaft? I wonder if that has anything to do with it? Mine is very light so it surprises me. Have a look and let me know what you think?

[@johnboyt9]

Fingers crossed , I’ve just taken the bottom of the leg off and impeller housing gasket has deteriorated which has turned the oil into the white coolant kinda mix in the propeller housing , kinda get the feeling the person I bought it off hasn’t looke after it as well as they said but advice on where to find a loose hose would be great thanks

@@dp47280 I ran my engine the first tank with 100ml pentane added. This was just to rinse out any impurities. Pentane is very gentle. It is cheaply available as lighter fuel, naphtha, Coleman fuel or benzene. In the past, benzene was a six carbon ring fuel, but because of the carcinogenic properties it was replaced with pentane
