Considering a new Supra SA or SL but wanted to gauge which motor to go with between the 400 and 450. Normally the crew is small (4-6 people) and more of a surfer than wakeboard these days. As of now the plan is to run stock weight and then add a little lead later if needed but no intention of sacking it out.
Is the 400 enough or 450 recommended?
Note: I am in Houston, TX
400 is all you need at low elevation even at full load.
$8400 is a ton of money for 49 ft.lbs of torque.

If you’re getting a new boat and you can get the 1.76 transmission with the 400 that’s likely just fine. If you’re getting the 1.5 and you’re a heavy surfer it becomes a tougher question—and would be a no on the 400 in an SL for me.

The SL is only 150# and 9” more than the SA.
I believe the intent of the 450/1.76 is a low cost high elevation option versus the 575 supercharged.

I have the 400 in my mondo, yah, its a smaller lighter boat but wow is the power incredible. With the right gearing, and prop on the supra i wouldn't see the 400 as an issue.
Also the Supra Launch System helps a lot.

I have owned 2 Supras, a 17 SA400 with the Acme 2775 prop and now a 18 SL550 with the Acme 2247 prop My buddy has a 19 SL450.
My SA had 650 pounds of lead and with 4 adults and 2-3 kids it always struggled when the ballast was full to get on plane. I would have to move more people to the bow, drain ballast and switch to the advanced wakeboard profile to engage auto-launch and still it would take forever to plane out.
The 550 is obviously a different story, but my buddies 2019 SL450 is night and day different than my 400 was.
If you can demo both the 400 and 450 I would load them all the way up and see what you think. Personally I would not buy the 400 motor in a SA or SL, but I would be happy with the 450...it's a big noticeable difference over the 400.
Here in Houston the 400 works fine. My 17 SA pulls to 11.9-12.2 surfing no problem with Enzos and 600# lead, with a 2419 prop. The old 2775 would struggle if there’s more than 5-6 people in the boat.
If you’re gonna run stock bags and lead, the 400 will do everything you want it to.
Grab 750#, that’s what the PWT boat was running!
BP, tell me more about the 2419, I am running the 2775 and pretty happy. But need a spare.

It really just depends on how hard you want the motor to work......I know Rinker's orders most of their SLs with the 400 and they say they do just fine. I would say it kind of depends on if you are the type to trade boats every 2-3 years or if you keep them 10years+. If you trade in every few years and you want to you might give the 400 a go but if you will be keeping for a while then I would go 450. That being said we went with the 450 in our Makai and it is amazing!! The 450's performance (motor, trans, & prop) is a noticeable difference over the 400. The HP and Torque increase is nice but the kicker is the 1.76:1 transmission. Not only does it have a more favorable gear ratio it also allows you to run a larger prop which is a plus as well. Some of the other manufacturers have already gone to something similar to a 1.76:1 with some going to a 2:1. It is definitely some $$ to move up to the 450 but worth every penny IMO.
