New 4 stroke race engines?

[Davidlake]

When Mercury replaced my blown 300xs powerhead under warranty, they emailed me a satisfaction survey. I contained questions regarding purchasing other brands and why I would. I wrote that if a manufacturer would produce a high-horsepower/lightweight performance engine for performance boats, I would switch brands and purchase it. Let's see if "they" list and what they do!

I think what RBT is saying is that without any engine build rules that same power head could generate more then the 400hp it does now

Yes. That's exactly it

[powerabout]

Yes. That's exactly it

Love to see the dyno sheet on a 400 one, 360 from a s3000 is kind of normal

Ya I am sure you would, 345-355 is stock depending on who's Dyno

would you think this boat is powered by a pair of verados?

Do you really think Mercury cares what you want for 10 or 15k when these come off the assembly line for 350,000

Anything that makes a simple install, the boat builders are all for

a current f1 (UIM) is roughly 400 hp and have rules, there is more left without them. And weighs 175 lbs and has a flat torque curve compared to motors with gears.

Unless the F1 rules changed since 2012, the motors aren't putting out 400hp. I spoke to Alex Hledin (builder of Alex Carella's 2012 World Championship winning motors) and he said he couldn't get 400hp out of the motors. Have the rules changed in the past two years that allowed more hp from the powerheads? I wasn't aware of any changes in years - they're still running the spec. computers that I know of.

[RBT]

Alex didn't have a thing to do with Carella's motors. That is Brendan Power.
On the other hand Alex did do the motor for Phillip Chiappe who won the world championships this year.
Before the spec box things were different. 400 is doable, and then some. Not to be a dick, but things have changes since 2012, and even before that 400 was broken.

Who did chiappes mods back in 2013 that were ruled illegal?
Filler in the ports I believe?

****, you're right.........Alex built Sam Selio's motors in 2010 when he won the Championship (the years are getting away from me). That's the same year Alex built Shawn's motors and he won the Champ title here in the US. Anyway, I talked to Alex for a long time at Kankakee that year (2010) and he said that with the rules that were in place at the time, 400hp was not possible out of the F1 or Champ motors - that's why I asked if the rules had been changed. I haven't followed it that closely in the last couple years, but I didn't think the rules had really changed at all. They're still handing out spec. ECUs before each race, aren't they?

[powerabout]

So the rules still are you cant add material so grinding only?

Here he is.. To be unveiled in the Miami boat show 2015. 400 hp Max RPM 7000 with a Sportmaster lower. Orders will be taken in March.
