Anybody got a Z520L dialed in yet? Wondering about speeds with the new hull. Same as the Z520C or slower?

On 10/16, Hicky214mx posted a gps speed of 75.6 in his 2018 Z520L. So it doesn’t seem to have slowed down any. Changes from the 520C of last year are cosmetic.

I was told years ago by Mercury that not all motors leave the factory with the same HP there was a +/- acceptable range and if I remember correctly he said +/- 10%
Highly doubt there is that much variance. Prob more like 1-2%... what you might have heard was they can actually make within or up to 10% more of their sticker HP.
I used to get to dyno a bunch of motorcycles, and stock hp for a given year/make/model was pretty predictable within a couple hp. Production engines, while not a close in spec to "racing division" or built (by a professional) engines, are still held to pretty tight tolerances

That's sounds pretty good. I was wondering if they changed the bottom of the hull at all.
Ive had a two boats now that had new Pro XS installed after 3 years use and have noticed considerable power differences between each. Same thing for 3 blade furys. Ran a test with 6 props all consecutively, there was a 4 MPH variation from best to worst. And the best prop was the seccond one run.
Were the engines the same year? If so and one was significantly/noticeably stronger there might have been an issue with the other... With that said, there are always "freak" engines (aka Wed or Friday engines) that dont adhere to the 1-2% variance, just hope you get one of the GOOD ones
Now props, that's a different story! A lot of variance in those, 3 props will usually all run different, and why mine always get sent to Brian after I do a base run

If you have noticed the ProXs motors always have a little carbon in the exhaust when you uncrate them. It is my understanding that they all are given a test run in the factory coming off the assembly line hooked up to a test apparatus checking for horsepower and other factors.

I have been told by a Ranger representative that the pad is different. I was debating whether to order the "L" or the "C." Personally, I think the "C" looks better. I was strongly encouraged to get the "L" in that there had been reports of skidding on the pad with the "C" when engaging in a tight turn. I was told the "L" would not do that. I have no idea is this is factual or not, but I opted for the "L". It sounded to me like the "L" is the future.
