New 1.9L HO Engine

[Jetstream John]

I can’t believe that I can’t find an on the water in the boat review of the new 1.9 HO engine in Yamaha boats. I want to see the performance difference and top speeds. I want to hear from people familiar with both engines compare them is it worth it are they better etc. Has anyone seen any reviews like this? If so please point me in the right direction.

You do realize this was a new announcement in the fall when boat orders were taken, and many have not taken delivery of a 1.9 yet right?

The boat mags should have info, but I don't think very many have had seat time, other than at the dealer show last August. And even then, unless they were able to ride two similar boats, it would be a tough comparison. There is more power and less noise, but I would bet many will not be able to make the comparison unless in the same day one after another.

Anyone got an update for this? Really curious on how the naturally aspirated 1.9 performs in the 190 series. Have yet to see any on water reviews of the 190 in a boat and not in a pwc.

I’ve got one with 10hrs now. AR190 coming from an 19’ SX190 so same hull. I can’t really see any speed improvement, in fact it may the same .. I’m getting 38 to a very very top of 40-41mph gps. My sx190 was a hall sensor and topped out at 41-42mph. Probably more 37-39mph gps. It seems to be a bit quieter, maybe 10%. May also tow slightly better. All in all, hard to tell a difference. Wouldn’t do it only for 1.9

I have a 2024 Sport E 222 with 1.9L engines, for me the 1.9L engine is quieter and smoother, way less vibration and no engine drone noise while cruising. My boat tops out at 50mph

I just got a 2025 222 XE. Highest speed I've hit is 52 MPH with a full tank and two passengers (330 lbs total) and the water was slightly rough. I think in perfect conditions it could do 53-55 MPH.

I've got the boat to sustain 50 MPH in really rough conditions with 500 lbs of riders/gear.

On another day it was able to sustain 50 MPH with 1400 lbs of riders/gear with low wind and very glass water.

This is the first Yamaha boat I've been in so I can't compare it to the older engines. I'm really impressed with the speed. I also have a 300 HP Scarab 165 and the highest speed I've hit is 57 MPH.

The Yamaha has 400 HP and weighs over 4,000 lbs and is only 5 MPH slower than the Scarab that has 300 HP and weighs 1,700 lbs.

How was the break-in process for the 1.9s?

I don't recall the specifics (already at 20 hours), but it only required limiting your RPMs for the first 1.5 hours at varying levels (first 5 min, first 30 min, next hour). Its laid out in the user manual for the boat.

Your 222 SE weighs 3982# + 70 gallons of fuel 420#=4402# / 400HP (provided you were at sea level on a 60° day) =1:11 power to weight ratio without people or cargo which is great. With your two people +330 that works out to 1:11.83.

According to Scarabs website the 165 w 300 hp engine is 1600# plus 20 gallons of fuel 120#=1720#/300 = 1:5.73 power to weight ratio and it has a 7’1” beam, a thin blade! . That boat must accelerate pretty damn hard.

I like to run the numbers too lol....


That is just one tab and its filtered to just the boats that I own (my scarab is customized so its numbers are different from stock). The Yamaha 222XE numbers were from reviews I found prior to buying the boat. The reviews of the 222XE had performance numbers that were wrong. 47 MPH was highest top speed in one review, and another said 43 MPH but they were using the California version with a catalytic converter. I'm happy that the boat preforms a lot better than the reviews, but it also uses more gas than the reviews stated. I can't remember exactly, but I believe the boat burns about 31 GPH at full throttle, whereas the reviews says 26 GPH.

I also have an Axis T220 which is a dedicated wake surfing boat (22 ft long). Its great at making waves, but it sucks at being a boat. Its slow, it has a flat bottom so its horrendous in chop (far worse than my 16 ft jet boat), it can't go in shallow water, and its low speed control will make you look like a noob around docks no matter how experienced you are.
