    MJHSupra. Let me ask you this question since you have the boat I am ordering. I ordered the SL 400. I plan to add 6-800 lb lead bags. I am still nervous about the boats ability to pull its heavier weight, ballast and 6-8 passengers. I do plan to upgrade the prop. Have you found the 400 to be needing more torque? Do u use extra ballast?. It was hard to digest having to spend and extra 8300$ for an extra 40 lb/ft torque. That's the cost of a whole engine! Just trying to reach some peace with my decision, it's too late now anyways. Which prop are u using? if you upgraded.

    You have to remember that your 400 will have the new vdrive ratio which will help it. The 2018 had the 1.5.

    Hmmm, did not account for that. Just went to the website and saw it, the new 1.76:1 gear ratio. Wish they offered some kind of real world metric that would give an idea of difference in torque/advantage between the new setup and the one in my Mojo. I did test drive a 2020 SL 400 last fall. With full standard ballast and 4 adult passengers it seemed to do well.

    A 400 with the right prop goes a long way even with a 1.5 transmission.

    If you are at low elevation you really donít need a 450.

    I have a SA400 with 1.5 gear and 2775 prop at 1000-2000 feet elevation, 5-6 crew plus 500 lead and never had an issue surfing or wakeboarding.

    In full transparency, I have not tried full ballast, 5-6 crew +500# lead at wakeboard speed.

    Witnessed this exact set up riding in the PWT SA550 and I donít have anyone in my crew with the balls to ride that wake.

    If you ordered a 2020 SL400 you donít want a 2775 prop. You get a choice of a 16x17 or 16x15 prop, I would opt for the 16x15 prop. You can throw a 16Ē prop due to the 1.76 gear.

    OK. Did some reading on propeller pitch. Now, does anyone have the 16x15 prop option on a new Supra with the 1:76 tranny gear ratio? Or know of someone who has it?. I know these boats are not built for speed and I'm not concerned about going fast, but, how much top end speed am I sacrificing by going to lower pitch. I don't mind loosing 2-4 mph but it would concern me if max speed dropped to the mid-hi 20's . Anyone have any info on this?
