Suzuki 9 9hp outboard conversion to a 20hp

[@ergediav]

Hello, I'm Eric from Chile, first, thank you for sharing your experience, second, ask if you notice, in addition to speed, an increase in strength, that is, adding more weight to the boat and achieving better thrust, I say this to raise the family and have better overall boat performance, not just speed. Greetings and thanks

[@ReelLifeWithMike]

I did find not only in speed but I was able to get a different prop that would have more thrust for sure. It’s not crazy but definitely an improvement

[@michaelwhary7722]

thank you I have the 9.9 manual start and everyone does the conversion to the 20hp with the electric start well the ecu are different for the two of them and you got me on the right track for the one I need Thanks again well appreciated

[@ReelLifeWithMike]

Not a problem. It may sound stupid to change the ecu but it did make a big difference

[@ergediav]

You are right, the other videos I saw were for electric and manual starting, but the ECM code changes the electric one ends at L20 and the manual at L30, this video was very specific on that, and I appreciate that I may have made a mistake. Thank you so much

[@rickarmbruster2895]

Great stuff Mike … although the info isn’t directly relevant to me now, there was a period of time when I was looking at new ‘used’ boats I came across the same “opportunity” that existed between early 2000 models of Yamaha F70’s and 90’s by change out of the same components. Great info for Suzi users! And nice job in how you documented this 👍👍

[@bypyhgyk]

Khe khe.. now we do know where you do live. Will start sending gifts to that address. Thank you for the explanation video :) Very helpful.

[@RobB-vz2vo]

Thanks for showing how to re-power cheaply.

[@omieyouknowme]

Mitsubishi licensed their ECU to Suzuki/tohatsu/Yamaha they all use the same unit with minor difference. Pretty cool, you can do this in tohatsu/mercs but Yamaha still in 1990 with their 9.9/15 motors sadly. Even their 20hp is 30lbs heavier than the efi zuk and tohatsu. Honda are unique, but their service centers few and parts costs more some reason.

[@erickdash2295]

GREAT!!!! Great video, Where's the sea trial and SPEED TEST????

[@ReelLifeWithMike]

I ended up selling the boat and not getting that video done. But I do have a top speed video at the bottom of my KZbin videos called maiden voyage

[@270logan]

I’m trying to figure out if I can do this to my 2022 9.9 the website only goes up to 2020 for the 20hp

[@mohamedoulkadi9259]

Great video👌🏼 Nice explanation. Thank you sir 🙏🏼

[@ReelLifeWithMike]

Hey guys. Sorry I haven't had a tonne of time to respond. But I think I may redo this video with a lot more information including prop sizes ect. I may also include a speed test before and after with the DF9.9 to DF20. Stay tuned

[@mokhtarkheiry3089]

Hey Mike, thanks for sharing! What's the good prop size after the upgrade and from where I can order it ?

[@thijs.k932]

Thanks for explaining! Very Really helpfull

[@donc2334]

Greetings from Toronto...Great video!! I am confused about which 20hp ECM to install. You mentioned 33930-89L30. In another video the guy switched his 2021 model to 33930-89L20, and when I contacted Crowley Marine and gave them my VIN (slightly different than actual in case it's reported to Suzuki) they suggested 33930-89L40. So I'm stalled at doing this upgrade until I can resolve it. Don't know if I'd be allowed to return for refund if I chose incorrectly. I have a 2021 DF9.9BTL with elect start. Thanks for any suggestions on this!

[@ReelLifeWithMike]

Thanks for watching. Mine was not an electric start and that’s where it could be an issue. If the other guy had an electric start, I would go with his serial number.

[@franciscocubano227]

Hi, I have a Suzuki 6HP 2021 can i do something for more HP ?

[@Harold-m1z]

I was told by a Suzuki Tech that you dont have to change the ECM it will automatically adjust for fuel rate.

[@ReelLifeWithMike]

Removing the restrictor plate will allow more air flow and the original ecu will accommodate and add its fuel ratio. The removal of the plate will jump it from 9.9 to about 15hp. The reason for the way is that not only will it regulate the air and fuel ratio, it’ll actually adjust the rpm and timing to get a true 20hp. If that makes sense. But yes by just removing the restrictor plate will be noticeable for power just not a true 20hp withought the ecu.

[@Harold-m1z]

@@ReelLifeWithMike yes I do agree with what you are saying also..I have watched other videos and a guy gave this # for ECM 33930-89L20 for 9.9 to 20. Mine is an electric start, are there two different ECM's for pull start and an electric? I don't want to purchase the wrong one.. And thanks again

[@thatonebeone]

nicely explained .. good video

[@tucanman9775]

i have a df 20 the 9.9 cowling and no registration thats the key how much for the decal ?

[@alansmith2203]

Great video Mike. Geez, i can't resist this upgrade. I have a 30 foot trimaran and love my 9.9 hp. Being able to tap into twice the power during a "holy cow" moment is worth 500 bucks anytime and anywhere. One question, Have you had anytime to evaluate fuel consumption at 20 hp versus 9.9hp? I'm not talking WOT stuff...but everyday, seat-of-the-pants, experience between the two setups.

[@ReelLifeWithMike]

Hello Alan. It Definetly uses more fuel but haven’t done a full comparison. After the amount of questions and responses I have had I will be making a secondary video to this one but I’m more detail including prop pitches, speed tests and fuel consumption. As you can see there was still snow so I did the minimum but now it’s summer I’ll Definitely redo the video as a part two. Stay tuned.

[@srileo]

Fantastic video on a rare topic. Wish i could find one for Tohatsu.

[@craigmeredith1600]

@@srileo I believe it is the same concept for the tohatsu but you need to have the 9.9 350cc EFI motor not the 9.8 208cc one. The 9.8 is already putting out all that she'll suffer.

Do you have to change prop?

[@rerun1957]

Did you change the prop?

[@sandman4487]

Would these same parts you used for the Suzuki 9.9 work on a 2021 Tohatsu 9.9?

[@ReelLifeWithMike]

Not sure about that. I would have to check the block and construction.

[@sandman4487]

@@ReelLifeWithMike ok. I've been told they are pretty much the same motor. You're Suzuki 9.9 looks exactly like my Tohatsu 9.9. Good video by the way and thanks for the quick reply. I'd love to see what you're new upgrade will do on the water.

[@wheelieking3976]

What happens to the five year warranty of your engine???

[@raykeogh1972]

Hi you have been using this for a year now if you still have it that is. Have you have any problems since the conversation? I am just in to boats and have a honwavet38ie3 with a 9.9 hp Orca. Orca are all Yamaha parts do you think this is possibly the same so could convert? I am not going to blame you for any advice you say because the decision is totally mine not yours. My boat is only getting up to 14 knots and my brother in law now wants to come with me and a lot of my journeys but he is more than twice my size and weight and to me if the weather changes we have no chance of getting back lol. Hope you reply but thanks for the video anyway. Ray K UK 🇬🇧 YNWA.

[@ReelLifeWithMike]

I recently updated to a larger boat and ended up selling it just after a year. I had it tested and checked over and there has been no issues whatsoever. I’m definitely not a boat mechanic, but have a lot of knowledge in that area. I believe anything with a mass airflow sensor should be OK as a computer would adjust the gas to a ratio if it was electronic fuel, injected.

[@rickfaessler1386]

How's the Suzuki 9.9 running? What prop did you go with? 10 pitch?

[@ReelLifeWithMike]

It’s running great. Had the dealer service it at the beginning of the year and they said it looks good. Yes I ended up going with the 10 pitch. That brings me to a top RPM of 6230 at full throttle. Optimal is between 5300-6300

[@markkus1134]

Can this be done on the carburetor model?

[@ReelLifeWithMike]

I don’t believe so. Then you would have to change the fuel pump and injector nozzle.

[@bryanfisher9077]

Will this work on a 2024 DF9BS5?

[@ReelLifeWithMike]

As far as I know unless they changed it but I doubt it. The easiest thing is to check a website called Browns point Marine. All you have to do is find your model number and then look at the ECU of the motor you have and the ECU of the outboard you’re looking at and see if if the part numbers are the same if that makes sense.

[@chadbosko8935]

I don,t know if u mentioned it but how much faster did it go, is it really worth the trouble , does it really move like a 20hp. And whats the cost $500 US.

[@ReelLifeWithMike]

100 percent goes like a 20hp now. So the whole point of doing this is having a 9.9 to go on restricted lakes but able to bump it up to a 20 on larger lakes. The pricing in Canadian dollars between the 9.9 and 20 hp it’s about $1300 Canadian. So you only save A little bit by doing it yourself but you have the option to go back to a 9.9 in a restricted lake. In my boat I would go about 13 to 15 km an hour with a 9.9 and about 40 to 43 km an hour with a 20

[@ReelLifeWithMike]

I will also be doing a new video or I should say updated video with a lot more info in it coming up

[@SP_Hatter]

@@ReelLifeWithMike So the 9.9 and 20 are the same chassis? I am trying to put remote controls on my and see parts for the 15 and 20 but nothing for the 9.9 and if the 3 are the same that would make sense and the parts would be interchangeable.

[@johangrannas4837]

So any idea whats the difference between DF9.9A and DF9.9B?

[@mozzyviator2939]

A is carburator model and B is fuel injection model 🤷‍♂️. Complet different engine A model is a 208cc and the B model is 327cc.

[@trevorstafford8495]

@@mozzyviator2939 the guy in the video said the A model is also fuel injected... this is incorrect then? The A model cannot be converted up?

[@masterofnone2705]

What prop are you going to upgrade to?

[@ReelLifeWithMike]

Hey sorry for the late response. I am currently using the 9 1/4 x 10 as of now.

[@jamesmurtha1355]

Do you know if this mod can be done to 2022 Suzuki models?

[@ReelLifeWithMike]

Yes. This was a 2021 model and they kept the same concept

[@jamesmurtha1355]

@Reel Life With Mike thanks Mike. I can't find 2022 ECUs on standard Suzuki parts online stores (e.g., Ed's Marine) and so one guy mention in a Reddit thread that he "heard" they changed things for 2022.

[@ReelLifeWithMike]

@@jamesmurtha1355 it may change but if anything the parts may be to new to get on catalog. Keep an eye out on browns point marine as well. Check part numbers and see if they changed. Best of luck

[@jamesmurtha1355]

@Reel Life With Mike I meant Browns Point not Ed's Marine

[@stevengagnon6799]

I went right to the source and emailed Suzuki customer service with very same question for my 2022 model and the part numbers listed in this video. They said the parts are compatible with the 2022 model 00995F-240000 series.

[@robertroigsantamaria]

it must be possible to mod or reprogram the MCU ....

[@ReelLifeWithMike]

From what I heard you can reprogram it. The hard part is that there’s not a lot of people that do it. Also I wanted to be able to change back if I needed

[@robertroigsantamaria]

@@ReelLifeWithMike this is most interesting. .. 400+€ for a new one is too much...

[@GunnarsGames]

Yeah, but he gets 2 power options for the price of one.

[@ReelLifeWithMike]

I totally understand what you’re trying to say. But the hard part is I got the 9.9 so I could go on smaller lakes. But having the option to go from 9.9 to 24 that price range worked awesome for me.

[@gunsandrotors8704]

You do realize what you are showing in your video is illegal. How bout letting people figure this out for themselves. Now that you drew attention to this. Im sure the engine manufacturers will change something and you made law enforcement aware of what to look for. Great job.

[@ReelLifeWithMike]

I figured this out from another video and got the parts from a certified Suzuki parts dealer. Also the dealer was the ones to direct me on what correct parts to get do do the conversion. Outboard manufacturers and people have been doing this for years. No different then chipping a car/truck or changing the throttle body and cams on my big block so cool down buddy.

So Suzuki in Australia are charging me 2 grand extra for the 20 hp model? Are you serious?
