Spark Plug Showdown - Yamaha Boat Speed Test

[@mikemessana6268]

Definitely not getting those iridiums! Thanks for an informative comparison!!! 👍🏻👍🏻👍🏻

[@rhtufts]

Your naturally asperated 190 is just as fast as my supercharged 195. Best I've gotten is 48 mph and that was with just me and wife and a 1/4 tank of gas. Thanks for another great video!

[@CaptainLeonsBoatingandMore]

Thanks Russell, yeah for general boating the 190 does great. If you need that punch for watersports the 195 is better. The difference in fuel burn at WOT is significant though.

[@hmunoz1984]

Yes mY 190 only hits 42mph on the calmest day. And you said you don't have any mods? Have you tried the ribbon delete?

[@CaptainLeonsBoatingandMore]

@@hmunoz1984 nope. All stock. No interest in ribbon delete, there is a reason it’s there. Feedback has not been great on it anyway.

[@mrfofung]

Have to replace mine this week. But I didn’t get iridium lol!!

Can't wait to catch you out on the Forge River for a 252SE vs. 190SX drag race! 😎👍

[@CaptainLeonsBoatingandMore]

If I put any weight into the boat, you will speed right by me.

[@mikemessana6268]

vs my sx240 too! lol

Fantastic, Captain Leon! Another excellent video!!!

[@CaptainLeonsBoatingandMore]

Thanks, and looking forward to your next one!

[@mattleonard5268]

Would you experiment with premium gas and maybe fuel additive?

[@CaptainLeonsBoatingandMore]

I tried Premium once, had no effect, just a waste of money, unless required with supercharged engine. I use StarTron fuel additive with every fill up.

[@kkutube1972]

I think it matters if you have a supercharge. Just like a boat running 87 but I think an 89 is just for security. For my supercharge jet ski, I have to change the oil every 25 hours and the plug to inspect or replace it every 50 hours. The plug is cheap compared to the price of the ski, and since I am already removing it, I just might as well replace it.

[@CaptainLeonsBoatingandMore]

I hear Kieth, makes sense. Thanks.

[@joedemola9636]

I could have told you this from motorcycle experimenting many times ... Stay with OEM always ..other than that .now get rid of that stock air filter for k/n and pop out that restrictive flame arrestor ribbon as the KN has a metal screen on it to replace any back spark .. that's a test you should do and I bet you hit 50mph !!

[@CaptainLeonsBoatingandMore]

I hear ya Joe! Thanks, and thanks for watching!

Good stuff Leon!

Thanks Hank, and thanks for watching!

[@ttvdecimatedbyme9130]

Were conditions very similar? I didn’t watch the entire video but was the wind direction, outside temp, tide and everything the same or similar?

[@CaptainLeonsBoatingandMore]

Basically the same yes. When you have a full 9 minutes perhaps you can watch it to the end.

[@eric3921]

How is your SX 190 going that fast?I can’t get mine over 40..

[@CaptainLeonsBoatingandMore]

It has to be perfect conditions. Right weight on board, weather and water conditions need to cooperate and these engines like cool temperatures too. Also the post 2019 models are not as fast as the earlier models due to hull design changes.

[@stephen.lorefice]

Can you link the oil you use and where you got that little mirror? I have an AR190 and I top out at 42. Wondering if the oil is the difference (or the little mirror haha).

[@CaptainLeonsBoatingandMore]

Hey Stephen, Amsoil is generally not sold in stores but you get it directly from authorized dealers. Just Google Amsoil and you will find how to order it. It's not cheap but probably one of the best synthetic oils made today. My experience from using it versus Yamalube was the engine obtained slightly higher RPM and my top speed improved by 2-3 mph, at least that was my experience. The little mirror was a gag really. My dad bought it for his car side view mirrors but didn't want it so I found a way to mount it in the boat. Try an auto parts store perhaps. Good luck and thanks for watching!

[@GiantsNinerFan56]

That’s the smallest rear view mirror I have ever seen…another great video..Do another trial using 89 octane

[@CaptainLeonsBoatingandMore]

It's just for fixing my hair and adjusting my GoPro head mount...lol

[@GiantsNinerFan56]

@@CaptainLeonsBoatingandMore 😎

[@squeaky61]

you run 87 octane? I assume it has ethanol in it? Did you ever consider running 91 non-oxy, especially to help with the winter storage? I run it in everything, just so I don't have to deal with starting issues after storage. Have you ever had starting issues in summer? Super helpful....I do believe that OEM is best.... and a service manual is gold! ha

[@CaptainLeonsBoatingandMore]

Only 87, thats what they call for. Never tried 91.

[@squeaky61]

@@CaptainLeonsBoatingandMore Is non-oxy gas popular where you live? Thank You!

Iridium plugs will last 3+ times as long as those copper oem plugs before needing to be changed

[@SmoknJaysGarage]

Good stuff!! Did I miss the fuel consumption comparison?

[@CaptainLeonsBoatingandMore]

I was waiting to see who would catch that, you win Jason! I neglected to mention that there was no noticeable difference in fuel burn, but with boats that is really hard to determine regardless considering weight, wind, current etc. always changing.

[@SmoknJaysGarage]

@@CaptainLeonsBoatingandMore so really no benefits, at least not noticeable ones?

[@BoogeymanDracula]

It will increase . Because ignition efficiency and timing will become better. But in reality, this increase will be intangible to notice. The reason why sparkplugs are upgraded are for durability and reliability when compression ratio or fuel-air ratio is altered.

[@CaptainLeonsBoatingandMore]

Sounds logical to me. Thanks for the input and thanks for watching!

[@JEEPIMPACT]

I think they are just supposed to last longer.

[@CaptainLeonsBoatingandMore]

I agree Hary!

[@ChristianGrest]

On naturally aspirated applications, I could see there being little to no difference. The biggest advantage is probably plug life. Now on forced induction the advantage would be more reliable spark with less chance of spark blow out when in boost. Just personal experience from car motors. But in the majority of instances, run what the OEM installs. No sense in re-inventing the wheel. Nice test by the way!

[@CaptainLeonsBoatingandMore]

Thanks Christian! Appreciate the input. Makes sense.
