TR1 HP HO

[I know You know]

Can anyone tell me what the real horse power is on these TR1 High Output motors on the 210 FSH series?

 

[Maillis]

85KW or 114 Hp

 

[Bruce]

Are they really called “High Output”?

 

[Grassman]

I sure hope not. I want mine to last a couple thousand hours and "high output" usually means the opposite.

 

[Bruce]

@Grassman, Yamaha’s high output MR1 engines have a history of lasting for thousands of hours with a similar displacement to the TR1 and 160 HP.

Then I feel much better. I'm still getting used to the jet boat thing and running 6k RPMs at cruise. But love the boat.

MR-1 HOs peak at 10,200 RPM. The motorcycle R-1 goes over 14,000!

MR-1 HO is 180HP... I've only got mine up to 7300rpm, even that seems screaming for this Harley guy.

 

[Bruce]

@Gary Willett, you do not have a MR-1. Your boat has a 1.8 liter unnamed marine engine. The MR-1 HO is a 1052 cc rocket.

 

[SgtBFGunner]

I stand corrected.
I learned something new today. Thought the dealer said it was a MR-1 HO.
1812cc's of HO 180hp at 7600rpm.

With the mr1 u are not doing much of anything until you are over 7k... Lol

It has been suggested in the past that Yamaha derates the output of their engines. At least that is what I found out a while back by looking at the kw output on the tags on the MR-1 HO engines. https://jetboaters.net/threads/what-is-the-difference-between-ho-mr-1-and-mr-1-engines-besides-20hp.13021/ You can convert the kw to hp but don't know if they derated these also. This article for those engines states 125hp. https://www.proptalk.com/boat-review-yamaha-210-fsh. Another will say 130, https://www.boats.com/reviews/new-yamaha-waverunner-tr-1-ho-engine-ushers-in-era-of-compact-performance/#.W31THFMpA_g. So it's a game of darts until someone pulls one and puts it on a dyno.

I can’t find any threads on the subject now but the 1,812 cc motors put out a little less than 180 hp per the conversion calculation, I think it came out to 177 hp, less if you have a CARB version. Yamaha stopped including hp ratings when it introduced these engine in their 240 series boats for the 2010 model year.

In searching for the conversion formula I did see this post indicating the hp of a stock 1,812 cc on a dyno.



For what it’s worh I have a wave runner with a 998 cc mr1, another with a 1052 cc mr 1 and a boat with twin 1812 cc motors. I also used to own a boat with twin 1052 cc motors. The 1052 has a noticeably better top speed and accererates a lot fast than the 998. The 1052 powered boat has about the same top speed as the 1812 powered boat but max rpm is 10,200 v 7,700ish, respectively. Because of this the 1052 make a lot higher pitched noise and I perceive it to accelerate faster than the 1812.

If the TR1 is only putting out 114 hp I hope Yamaha is not advertising it as High Output. If so they should qualify this with a comparison (e.g. to a 1994 wave blaster with 65 hp, a 1997 Seadoo pwc with a 110 hp two stoke or a new spark with 90 hp ho engine, recall that the base model comes with a 60 hp engine).

They really are called "High Output"!!!!

High output is relative, C cups on a 90 pound chick look big.
On a 400lb chick they look small. High output is just a term used for marketing, no statistics to match up to it.
