I read on Yamaha's site they advertise a 55mph top speed. In most review videos I have seen, it is more like 50-52mph. But, I have not been able to get mine over 48mph so far. The lake I go to is at 800ft elevation so I don't think that's affecting anything. Did Yamaha inflate performance a bit or is mine just some slower?

Also, this boat seems to be affected by weight way more than my old sterndrive boats. 48mph with 2 on board, 42 with 5 on board. I never saw that type of drop from a few more people before. Is that normal? Thanks!

Ribbon delete done on a 60 degree day. I was the only one on the boat, but 56 ain't bad (not GPS confirmed). Fuel was regular with a ton of Stabil from the winter.

Does that ribbon delete help?

Also, I thought the speedo in the 212x was a GPS speed?

I'd be happy with 50+ anything really. I definitely expected a 52-55mph boat when I bought it!

Ribbon delete added 2 mph. Not sure if the spedo is GPS? Makes sense though.

The least amount of people I've had in my boat ever is 4 and the max speed I've ever seen so far was 46 mph @ around 7300 rpm. I too was expecting to be able to hit at least 50. Speed isn't really an issue to me but its more about my boat performing as it should and wondering if it is and if not, why? Haven't really dug into this aspect of the boat yet though. On the surface it seems to run excellent without any issue like cavitation or anything - just tops out before I would have expected this boat to.

Mine hits close to 50 with 4 aboard and Bimini open. I hit 55 once when I was the only one aboard and the Bimini was closed. Close your bimini, otherwise it’s a giant parachute.

What RPMs are running at top speed?

The Bimini is a parachute and I’ve hit 50-51 w/it open by myself and 70% fuel, have no doubts could get closer to 55mph w/it closed and less fuel load and gear on the boat... but I’m at 300ft elevation & rpm @ 7600-7800

Be helpful to me to get a full pictur comparison if you know what rpms you are at when you guys are hitting these speeds.

My only real try at a top speed run was with a full tank of fuel, 2 people on board and the bimini top not extended. At 600' elevation, I hit 48mph. No clue on rpms since it was my first time out on the boat.

If I have 4 on board and the bimini open, I can't get over 43mph. Pretty disappointing.

I am gonna do the ribbon delete and see what that does. Anybody know how long that takes on these boats? Thanks!

I guess I need to do some research on the ribbon deletes and what is necessary. I definitely would like to see speeds close to what @geohil is seeing!

2017 2012X here - I've seen 49 max with bimini up and <50% gas. That being said, the Connectx says max is 55 - not sure if that's true or simulated at the factory : )

Probrably driven by a horse jockey with less than 10% fuel, no carpet, nothing but a stripped boat.
