Axis Wakeboard Boat Forum

My boat came with the 2249 but I wanted something a little stronger, I tried a 2313 since it was the least aggressive 12 pitch prop but my rpms were running a little higher than I wanted. I tried the 2773 next and it felt just as strong as the 2313 but got my rpms back down under 4k @ WB speed. The 2773 does run a little more rpms then the 2249 and less rpms than the 2313, It feels a lot stronger than the 2249 and as strong as the 12 pitch 2313. If someone is trying to drop rpms and is already running the 2249 a 2773 will not drop them more. But they won't increase by much.

Hey steveA20, when you tried the 2313 were you able to get on plane with full ballast?

Yes but not with wedge down. That was stock 800, sumo 475's rear, 400 under bow cushions and sumo 600 on top of bow cushions, have to drain rears a bit to plain out with wedge down.

My A24 came with the 2419 with the 409 motor. No issues at all and it's been a great all around prop for us. Highest elevation we see is Powell at 3600 though.

I must have some other issues then. With stock 800 plus 825 rears (only filled 1/2 full) and 750 under bow cushions (probably only fills to about 600ish), 2 people in the bow and 2 or 3 in the main area and cannot get on plane with the 2313 prop. I'm at 2200 feet for elevation. When I ordered the boat last spring (2016 A22) the dealer talked me into the 2313 prop but I wonder if that prop is meant for the older Axis boats with the different tranny gear ratio? Or maybe I just don't have enough bow weight?

You have more aggressive gears than the 1.48 ratio so the 2313 will pull more with your 2016 than then the old gear ratio.

Yes I guess that is true, so really there's no reason it shouldn't get on plane using the 2313 prop, if anything it should pop out of the hole and get on plane quickly with this prop and tranny combination. Maybe I'm just not running enough bow weight, I'll have to wait till spring to test again.

The A22 comes with 900lbs of stock ballast, belly tank is supposed to be 500 and the rear tanks are 200s. I did get an email once from Malibu about the tank setup and they actually said the belly was 450, the port side rear tank is 242 and the starboard side is 208. Also, the 2015 and up A22's can only get around 400lbs in that under bow seat bag. Wakemakers actually went to Malibu and did laser measurements for all the boats and with there measurements your only getting 390lbs in that spot. So yes, you need much more bow weight if your running rear 825s. Even half full your still running 1400lbs rear and only 850 bow with tank and bow bag.

Steve. How much of an rpm difference was there between the 2313 and the 2773 at WB speeds?

Around 300! I was at 4200 at 23mph and with the 2773 it dropped down to 3900 or less. I didn't feel like I lost any low end switching to the 13 pitch vs the 12.
