I just ordered the same carb and measured compared to the stock one. Looks like both measure 32mm on one side and 23mm on the other, exact same. So I’m confused maybe it is just a jetting difference? Hopefully it’s different cause it cost a lot just for that haha

I’m wondering the same. Did you ever figure it out?

@@dustinwachter9581 yes there’s a hole beneath the carb towards the back,it goes in that hole

Replacing the battery isn't hard

@@patgraeme775 No - but finding them is. Mfrs increasingly use oddball batteries. Don't get me started on how crap the battery housings tend to be. Current hood is a Vires I like a lot that charges itself, no battery required. Vision out is good too. Unlike many.

@@jamesward5721 how often do you use it? I just ordered the cheap yes welder hood to beat up at school

@@patgraeme775 I'm stuck welding 7 days a week every week - there's a pile of dead masks in the corner that's pretty chunky. :-) The Vires is my fave so far - prefer it to even 3m stuff. It takes severe hacking & still works great - plus the view out suits me - that's another entirely subjective thing - people like different sorts of views out - there's another 3 day old mask here that was far spendier - it has a deep green tinge to the view - I hate it, the other chap here loves it - so it's very subjective.

Mine has a dial on the side of the helmet.

I was about to ask,how u can get more hp from the same cc?? 😉

I’m curious about this also. I believe this model number is the same block as the 8HP. The 15hp has more displacement.

Well a question do y’all believe a 9.9 is more hp than the 8hp cause the 8hp and 9hp is the exact same motor so something causes it to goes a tad faster other than the displacement. I don’t think he gets 15hp from it but maybe a 11 or 12

I also replaced from a 4 blade prop to 3 blade prop. But before than it wasn’t much of an upgrade. The prop made all the difference. Sorry for not replying for 8 months I took a nap lol.

@@kostaswolf1978 I don't think it's a question of how you can get MORE hp from the same cc...it's how you can get LESS. They built the 15 hp and wanted to maximize the profitibility of that engine so they put a smaller carb on it and called it a 9.9. Then, with the same stroke of genius they made an even smaller carb and called it an 8. Really, it's a win for everyone. If you bought a 15, great, but if you bought something smaller and want to upgrade without buying a whole new engine, you can. The engine is reliable enough get away with this. Also, just think about if you were one of the people who bought the 8. For a couple of bucks you could almost DOUBLE your horsepower.

I haven’t had any problems yet I have been running it every weekend and hadn’t had my problems. The first two days I did have to adjust the carb but it wasn’t bad

I got a new prop also buy honestly it still runs 22 mph by myself

@@SuperEuriel I see. Well I wanted to attempt to pull the kids on a tube. Only have it on an inflatable boat so figured the little upgrade will be nice. Thanks for the update.

@@SuperEuriel I ordered a prop. Hope it’s a good one- 8.9x9.5.

I only had to do a little bit adjusting but not much and then it was good

@@SuperEuriel which screw do you adjust it with? this is my first time working on a carb of any kind

If it's running rich you'll probably need to adjust the mixture screw, usually it's a recessed screw that is in the aluminum housing. Look up the specs/diagram for your particular carburetor to find it's location and which way to turn it to increase or decrease air flow

It’s hard to tell but a few koi, bass a school of shinners, blue gill and a few pleco

@@SuperEuriel all you need is some boots and a rack of ribs and it’s the south in a pond

Lmao 😂

Lmao I’m in liberty, TX

I’ll be there

Yes I picked up 2-3 mph with just the carb swap and then after the prop change it picked up more. It was just a flat 4 blade to a 3 blade pitched

Awesome thanks!!!!

Like a 2 mph gain to be honest.

@@SuperEuriel thanks for the reply i have 17 9.9 and gonna get the carb as well

@@qapsukalek mine had a 4 blade flat pitch prop and I swapped it to a 3 blade and that made a world of difference

@@SuperEurielwhat does she run now with the 3 blade ?

I believe i was able to go 20mph I got a new boat since then and haven’t used it

I noticed a little bit of a difference but I ordered a new propellor and should be in today to test it out again. It was like 2-3 mile difference

@@SuperEuriel Where did you order the part from? Also, which prop are you planning on using? I have a 2022 9.9 that is in desperate need of some more power.

@@jasonlennon4128 I bought both off of Amazon the propeller definitely made a difference it’s a 14 tooth spline 9.25x9, part number 48-897750A11 for propeller and the carb came from Viking Powersports

Yes from what I understood

15 hp its bigger.. over 300cc

Theres a big block 15 and a small block 15. The carb he put on that 9.9 is from the small block 15hp. Its like 230 something CC's versus the bigger 15hp thats around 300cc's. I have worked on both.

@@orlandomoreno5326 i got a 9.9 hp and 209cc....even if i put a 15hp carb,i dont think its gonna give me more power from the same cc

@@kostaswolf1978 Yes it will because the carb has different parts to flow more flow into your engine, also the air intake is a little bigger. I upgraded a 9.9 to 15 before

He’s about to be a year old on the 24th
