Why There Are No 10 HP Outboard Motors

thats a lie,
you see honda outboards make 10HP

All 9,9 hp engines are secretly a 15hp engine

And yet I’m looking at a vintage 10hp motor as I watch this

This does not apply to the UK. There could be local restrictions but 10hp are available from all the major manufacturers.

Honda 100b is a true ten hp motor

10 HP doesnt exists because at 10 you have to register the boat
so you get up to 9.9HP, and not worry about registering./lic/ins.
if youre going to register, then after that you may as well just go to 25+

Alot of them are actually 15 or even 20 horsepower that have a restrictor plate so the company doesn't have to make more than one motor for a similar sized outboard

I have a Johnson GT 10, rated at 7,35kW, so a 10hp outboard does indeed exist.

10hp is now the norm in Scandinavia, before we had 9,9. But now 10 is 90% market standard. A little carburettor fix and their 15hp. 👌🏻

There’s some lakes around me that have 10hp limit. And if it’s over 10 hp you have to have a title for the motor.

I have a 10HP Honda outboard.

In Canada, you boat requires no registration if the engine is less than 10hp

There are loads of 10 hp outboards. Just saying.

wrong i have a 1955 johnson 10 hp

I had a 10hp outboard, Mercury 10XR 2 stroke

AZ has a 9.9 hp rule. I came to AZ from Colorado with an almost new i5 hp Yamaha. I do not know what their rule there is now but at that time they had a no-wake law; no limit as to hp. So coming to AZ I was in a quandary about what to do. The owner of a local boat repair shop advised me that the difference between a 15 hp and an 9.9 is the carb and the sticker on the motor. He sold me a 9.9 sticker and all is well.

Has to be taxes.
Its always taxes.

Edit:
So it basically was taxes and other rules, who knew.

Honda and Mercury make 10hp 4 strokes, the Honda BF6,8 and 10 and Mercury F6,8 and 10

EPA regulations thank you US Government bureaucracy...

to add to the story. you buy a 9.9HP outboard to avoid bureaucratic problem then an upgrade kit to get 20 hp out of your outboard.

They excist here in the netherlands, mercury 10hp

My 2011 Honda BF10 is a 10 horsepower boat motor. They do exist.

I tied 10 horses to my broken outboard. So obviously you're wrong about the 10 horsepower thing

Literally seen tens of 10hp motors but whatever

I have a 10hp Evinrude. So there is 10hp outboards

I walked past a 10hr Suzuki this morning

The 9.9 HP motors is also a thing in Europe. I'm not sure why, but I'm guessing taxes or regulations are the reason.

Yea im buying a pirate flag and gonna fly it on my boat

just bought a used 10 hp evinrude..............

Herr in Canada if you have a 10 hp or more outboard you have to register your boat and apply your number on the boat usually on the left and right side towards the front.

Kind of picky, petty B.S. video.

Wow! How much time and effort did you spend researching this. I watched maybe a minute and a half. Better things to do.

one word.......GOVERNMENT!!!

Anything 10 and over in Canada and US require registration. That’s why 9.9

So... 9.9hp outboard motors exist and are common then? So why would I care about this in any way?

Stop repeating yourself for content and just give us the answer. Annoying

A mate of my had one dude😂

I always figured it was a tax/licensing thing to see 9.8hp motors abroad. Meanwhile the same motors would be labelled as a 10hp motor here. Because over here the question of whether or not you need a license and registration for a boat is whether or not it can reasonably go over 5 knots. If it's slower than 5 knots, you probably don't need a license unless it's over a certain size or displacement.
So you can have a decent size boat with a 25hp motor on it, as long as it doesn't go over 5 knots when using the motor. You can go faster when sailing or rowing for example.

This can obviously only really be enforced by cops in a boat. And after a couple of court cases they have to measure the speed in two opposing directions, and then use the lower of the two, so they can't shaft you by making you go downwind, downstream, or both.

Tomos 10 is the only 10 HP engine that exists

Nice presentation.

10hp and 15hp engines actually have the same body, the only difference is the carburetor which increases the power, so if you have a 10hp engine and you think it is too weak, you can find a carburetor of the same type as 15hp and you have a 15hp engine

12HP Hangkai 2 stroke from Amazon on a 10.5ft Bris inflatable. Same weight as a 9hp 4 atroke. Goes 18mph. Boat and motor for $2000.

Johnson 10GT?

Just ordered a honda 9.9 HP outboard from online outboards. 👍 I'm excited

this no 10hp has been around for the last 50 years that I know of, so most probably well before these rules you state in the US, and we live in the UK where none of the rules you state apply

9.9 HP in Canada is the maximum hp you are allowed to have before having to register your watercraft. Anything under 10hp you dont have to register. Funny thing is, the weight of the 9.9 to 15 hp is the same weight usually. Only difference between a 9.9 and 15 hp motor is usually the Carburetor or reeds. Its the exact same motor otherwise, same prop, same lower end and same piston and block.

I have a 10 hp mariner outboard

Johnson made a 10hp in the 50s

Several people have commented that Honda still makes a 10 hp, and from the overwhelming number of comments, I believe it to be true. However, in the USA (where I am located) the Honda website only shows a 9.9 and no 10 hp. Obviously, the 9.9 and a 10 are the same engine and it seems that outside of North America it is still labeled as a 10 hp. I apologise for my "blanket statement" that there are no 10 hp outboards because it seems like this phenomenon is primarily a US and Canada thing. Also I do realize that "once upon a time" there were 10 hp outboards in the US and Canada - but it seems that era ended in the 1970s - around 50 years ago. So to those of you who insist on telling me that Johnson or Mercury made one in the 1960s, - I know they did. This video is addressing the several reasons WHY our 10 hp outboard motors are currently (and have been for the last 50 years or so) labeled as 9.8 and 9.9.
