This explains a lot for me. I had noticed that a lot of these 9.9 and 20 hp motors had the same displacement. I thought it was just a typo. Basically either just charging you an extra few hundred dollars for a better ECU which cost the same as the lower horsepower to manufacture.

It's not better ECU, etc, it cost of production, 9.9, 15, and 20 all have the same tooling, easier on inventory with just a few easily changed components and labels. If there is a big demand for 9.9's, no need to start making more, as in this case, change the restrictor plate, and labels and good to go. Cost of production reductions is profits

Really nice job, as always. I"ve watched this video a few times and and intrigued by the possibility of converting mine. I mostly use my 9.9 for trolling but occasionally go to smaller lakes with 20 HP limit. I do really like how my Suzuki can maintain a very slow trolling speed in colder weather....wonder if I could achieve the same speed as a 20??

I was just watching it again to make sure I got the parts right before ordering them. And then I wondered. since they are Mitshibushi parts, would they be cheaper if bought from Mitshibushi? I am researching this, but wondered if you, or your readers, already found this out? Please let me know what you found. I am not going to convert it until I am sure the 9.9 won't do the job adequately.

Is it likely there will be a similar strategy for the new 2023 models that are out.

Great video. what year is your motor please?

Been watching your videos for a while and in February 2021, I bought a 2020 9.9. The dealer told me it was new but it had a few small scratches. It now has 25 hours (from me) on the 9.9 ECM but the red light never flashed to tell me the the 20 hour service was due? Did you change the ECM before 20 hours and did your 20HP ECM start flashing after 20 hours? I since put the 20HP ECM and have about 25 hours on that one as well and still not flashing light. When I went for service, the service guy told me that someone had reserved this motor but ended up changing his mind. What I suspect is that they took the motor back after the guy ran it for more than 20 hours? Thanks in advance

I just bought a brand new 2021 Suzuki 9.9 fuel injected. Followed your instructions and got the ECM and the flame resistor with the silencer. But I noticed you talking about propeller pitch. What comes on these motors from the factory? Is it the 9 inch pitch? And if so should I switch to a 10 inch pitch? What’s the difference between an 11 inch pitch and a 10 inch pitch?

What was the website that you shopped to buy the stuff? I just bought a brand new EFI 9.9 Suzuki. I wanted your video but on my phone it’s hard to see and you went through pretty quick.

Restrictor plate = NASCAR. Are the lower unit 20 hp part numbers the same as the 9.9? This was too easy ! Nice job

Thanks for making this video. I am trying to decide which motor to buy for my Saturn SD330W, and I like the idea of buying the 9.9, but having the option to 'hod rod' the engine up to 20hp if I find that the 9.9 doesn't satisfy me. However, I was originally planning to buy a Tohatsu 9.9. First, I looked for video examples of someone who had converted a Tohatsu, but I could not find any such example. So, I looked at the parts catalog for the 2020 Tohatsu 9.9 versus the 20hp. Just like in your example, the only difference in parts between those two motors is a different size gasket, a different ECU, and the fact that the 20hp Tohatsu does not use a restrictor plate. But there is one BIG difference: The Tohatsu ECU costs about $850 compared to $450 for teh Suzuki one! Unless there are noticeable feature benefits on the Tohatsu, I think I'll just buy the Suzuki. Thanks again for your video and the information!

Thanks for the video. I have the 2017 suzuki 9.9 and changed the restrictor ring and propeller. Do you know if i would get more effect if i also change the ECU?

First of all, thank you for the great videos, including the other one with the propeller comparison. I`m looking to buy the DF15A since this is the maximum my inflatable is supposed to be able to withstand. But you never know what the future may bring, so this video definitely caught my attention. However, there is something I do not understand: the official Suzuki brochure lists DF9.9 and DF15 with a 44 kg weight (97 lbs) whereas the DF20 is supposed to weigh 48 kg (106lbs). Where is the difference coming from? I doubt the DF20 is sold with a 4 kg / 9 lbs heavier propeller... :)

This is totally legit! Suzuki made a 20 hp motor and detuned it to sell 9.9 models. You don't need to buy the seal, ONLY the flame arrestor and the ECU. You can put the flame arrestor into the existing rubber gasket. But no doubt, this turns your 9.9 into a 20 hp. The ONLY part numbers that are exclusive to the 9.9 are the restrictor plate and the ECM. After doing the change, the ONLY part numbers different between the 9.9 and the 20 are the decals!

The 9.9 restrictor comes attached to the seal to remove it you have to cut some rubber rivets then will spin.. did that before. And has that star shape inside. The 20hp seal is smooth on the inside endge and the flame arrestor removable

Would it be financially better to buy the 20hp and just switch out the 20hp sticker/decal for a 9.9? Seems those parts are pricey and the work to swap them.

Great video, I didn't know that the air intake was so restricted on a 9.9. On my old Honda BF15 the manual specified different spark plugs heat range for the 9.9 Hp did anyone tried a colder range? As for the propeller the torkier 20hp could benifit from more pitch, thanks again!

My question to you and anyone in the group who completed the upgrade to either 15 or 20hp is whether a noticable increase in power was noted at low to mid RPMs, or only at the high end because the WOT max was increased? For example would I expect to have greater speed (and therefore greater fuel consumption) at say 3500RPM (my expected typical cruising speed) after converting to 15 or 20hp? Thanks!

I wanted to ask if this would work for the 15 hp Suzuki could you convert it to a 20 by changing out the restrictor plate and the ECM, or is exclusively only for the 9.9 hp to 20 hp?

You sure can do it to the 15 too and gain 5hp more

What are the chances of getting caught on a 9.9hp lake with this conversion? Also, would it be cheaper to buy a 20HP and just swap the sticker, or is it stamped 9.9hp?

Does anyone know if there is a difference between the 2020 versions and the 2022 versions?

Have you tried running it yet without the 20hp flame arrester? Speed increase? Safe enough. Most two strokes don’t have any flame arrester. Thanks.

No i have not tried but highly doubt will be anything noticeable. Maybe in the rpm very tiny bit

That mesh has area, takes up space and creates turbulent air flow into the throttle body. I’ll let you know. I have the 15 that I have converted to the 20 hp with a 10 “ pitch stainless on a 12’ aluminum. Thanks for all your videos. They’re great!

What are the part numbers to do this on a 2020 remote control electric start? I asked my mechanic but he said they where back ordered.

@jason same part numbers you see in the video, mine is a 2020 electric start. Remote or not is the same.. the pullcord only is different part number ecu... then the grommet and flame arrestor same for all

I have a suzuki 8hp 2021 Ist it possible to upgrade the 8hp to 9hp? What is needed to change? Thx

Are both motors same CC ones ? Or the 20 has a higher CC powerhead ?

I want to do this so bad but do you know if this voids your factory warranty?

Most likely yes! If they find out. 🤫 I could not wait 3 years to do it so .. i did it . They are very reliable motors not see me having warranty issues with it in 3 years. But if i did you cant just put every back to 9.9 and take it to a shop.

But when you sell the 9.9 parts as new never used on Ebay you come out ahead. surprised this was not thought of...

Yes you could sell the 9.9 ecu if you dont want it but if you still have warranty keep it

Could you convert or increase a 25 mercury to a higher hp?

Great, can you do that with a Parsun9.9 as well, as I want to put a jet instead of a prop and you lose 30% in power

You cannot do this to your parsun, the 9.9 and 20hp parsun are two different sizes totally different

How much do the upgrade parts cost please?

Does this work on DF9.9BTHS3 model? mine is powered tilt. Just want to confirm before I buy. Thanks for the video.

@thecobovn Yes. Doesnt matter if its power tilt or not. What matter is matching the ecu to “electric start” or pull “cord start only”

I have a suzuki DF9.9A 2014 pull start, can I raise the power in this model?, if so, how?

I guess if you already have the 9.9, this makes sense. However, if you're buying the engine new, it's cheaper to buy the 20 than it is to convert a 9.9 to a 20.

Will this work for the Mercury 9.9 as well...??
