Yamaha 2024 line up …

You can see the models that get the new engines in the Press release I just posted above. Below to make it easy!

I'm interested in seeing (hearing) if the 1.9's run smoother than the 1.8's. I don't feel the need for more speed/power in our AR250, but a smoother and quieter engine would be nice.

Looks like 380 vs 400

360 vs. 400, and Yamaha under rates theirs a bit. If the throttle body is bigger it may be a bit higher.

You indicate the 190's but Yamaha indicates on their home page that they have a SC version of it which i thought went in the 195's? Am I reading their site wrong?

 

[@JC!]

They indicate on the site that both the NA and SC have 1.9's, at least on the 19'.

SVHO is still 1.8L for now, but the new 1.9L does have a SC block-off plate so it likely will replace the SVHO at some point.

Makes sense.

New engine new model, small increase, I would assume then it makes the previous models without the new engines go down somewhat in price used?

 

[HangOutdoors]

Ok, now we need some real world testing of the new engine. Also the rumor mill had it, that they did some work on bringing down the decibel level. Anyword on that?

 

[HangOutdoors]

I am looking for a comparison on weight from this year to last, I can't seem to find last years weight.

My math is off 180+180=360
For some reason was stuck on 380. I wish

 

[HangOutdoors]

The 222s is going to be a rocket with another 40hp or so and top end should go up.

They don't have any decibel reading info on the boats yet as the current ones are prototypes. Once they have production models we'll get the official info.

I am still planning on getting out on these boats in the next few weeks, so I'll give it a listen. Perhaps a little deeper sound?

 

[jthackman]

no one's mentioned the 25% lighter plant-based resin engine covers.....all that weight savings

more power = great
less noise = greater

 

[HangOutdoors]

Looks like it weighs 13 lbs lighter, the AR250 than last yea.r

 

[Ziess21]

Headed to on the water demo now, I’ll report back on the engine noise. I’m super curious about it.

 

[HangOutdoors]

Any word on changes to steering cables, etc.?

Introducing the all-new 1.9L High Output (HO) marine engine from Yamaha. This powerful engine is here to take your boating experience to the next level. Say goodbye to the old Yamaha 1812cc High Output motor and welcome the enhanced capabilities of the 1898cc, four-stroke, four-cylinder, 16-valve High Output marine engine. Experience quicker and smoother acceleration along with a higher top speed, thanks to its increased displacement and optimized intake and exhaust paths. Plus, with a 10-percent larger throttle body, you can expect more power and torque like never before! #PowerfulPerformance #EnhancedBoatingExperience
Let's talk about the incredible features and benefits of the 1.9L HO Yamaha Marine Engine:
1. Improved Charging System: We have taken the reliability of our charging system a step further by sourcing cooling water for the regulator/rectifier from the cylinder head instead of the exhaust manifold. This ensures that the 1.9L HO marine engine's water-cooled regulator/rectifier operates at maximum efficiency, providing ample power to support today's advanced onboard electronics. This means you can enjoy peace of mind, knowing that your electronics are powered reliably. #ReliableChargingSystem #EfficientPowerSupply
2. Crisper Throttle Response: To deliver a smoother and more responsive throttle experience, we have removed the taper on the new throttle body. This improvement makes our 1.9L HO engine a true competitor to other brands' supercharged motors. It also boasts a new throttle body design that offers better protection to vital electronics during service procedures. #SmoothThrottleResponse #HighPerformanceEngine
3. Easier Maintenance: We understand the importance of hassle-free maintenance, which is why we have made it easier than ever with the new 1.9L HO engine. With a relocated oil fill and thermostat, you can access them with ease. The crankcase assembly features a new shape, and we have improved the access for maintenance at the cam gear location. This ensures better oil flow throughout the engine, resulting in improved lubrication and cooling. Additionally, the new intake manifold design makes engine removal a breeze thanks to its long runners and flatter outside shape. #HassleFreeMaintenance #ImprovedEnginePerformance
To top it off, we have given the new 1.9L HO marine engine a modernized look with an all-new black anodized engine cover and exhaust manifold. Not only does it exude sleekness and power, but the engine cover also incorporates plant-derived cellulose nanofiber (CNF) reinforced resin. This innovative material is more than 25 percent lighter than existing resin materials and has excellent material recyclability, reducing plastics usage and greenhouse gas emissions. We're committed to the environment while delivering exceptional performance. #SleekDesign #EnvironmentalResponsibility

Down load a DB meter for your phone and check

we want to know everything .. top speed , on to plane , acceleration .. noise louder better !! .. is it that much better than 1.8s .. oh and also be specific which model you tested. TY

 

[@JC!]

Looks like the cooling in the heads/around the port is one of the biggest improvements, that along with the improved throttle body (hopefully the ribbon delete is easy) will produce the most potential gains in power. Greg has a good write up on the engine on GH...

Associate just called me and he is annoyed. He got his AR250 over a month ago and with the add-ons and stuff and from what his dealer is saying today about pricing, his 2023 cost more than the 2024 with the new engines would be. I told him to wait to new MY was released. He is bummed out.
