Hey guys, after 20 years with my 1999 x star I got a new (to me) Axis T22. It has the monsoon 410 and an Acme 2277 prop. With the ballast fully loaded and a few people in the boat it really struggles to get going. According to wakemakers I should get either the acme 2247 or the 2315. I was just wondering what most people go with.

nice ride. What year is it and what transmission? (1.5:1 or 1.72:1).

Thanks! It's a 2017. I'm not sure about the gear ratio. I looked through the owners manual but it doesn't seem to say, and the boat is at the marina.

OK for 2017 you should have the 1.72 tranny. I would try the 2247 next. when you say "ballast fully loaded" are you talking about full pnp bags too? Wedge down? What size bags are you running in the rear? That boat is going to need supplemental bow weight if you are running heavier than 550 pnps in the rear (or just don't fill bigger bags to the max).

Also... tip your tower speakers up a bit so they project rearward while under power (and save your cabin occupants a little bit).

Thanks so much for your insight. It's so weird for me to go from a boat that I know as well as the back of my hand to a boat that I know so little about. It has the 750 pound PNP rear sacs, and the 325 pound PNP bow sac. With all the ballast full and the wedge down and a full tank of gas it won't even get on plane with the 2277 prop.

I tried numerous different props on my ‘16 T22. Boat has the 350 motor. If I fully weight the boat I’m running the wakemakers 825lb bags in the rear lockers, a 650 under the bow cushions and another 400lb on top plus all of the hard tanks full. The OJ 950 is the ticket. It works perfect for me. Either wakeboarding or surfing. We wakeboard about 95% of the time so I don’t usually put that much weight in it but it handles it if we do. You won’t find the 950 online from the normal sites to purchase. Go to OJ’s website and contact them directly. Their customer service is as good as it gets. Awesome friendly and very knowledgeable. I wouldn’t buy a prop from anyone else.

Weight balance in that boar is way off, that’s why.

We have the 410 but with the lower ratio and run a 2773. It’s just barely not enough for us but it doe the job 95% of the time. The other 5% being when you have too many people lol.

You want 500lbs bags in the back and as much weight as you can get in bags up front, that will help solve your problem and also improve your wakeboard wake.

That's a very aggressive prop for that setup. What are your rpms at 30 mph?

It is an aggressive prop. Recommended by OJ after trying a 945 & 948. I believe the 950 is a 948 with more cup. I very rarely run 30 mph. Usually cruise at around 24-25. At 25 I’m around 3900 rpm’s. I’d have to double check where it runs at 30 but I would guess it’s 5000.

I have 2 props I rotate between, depending on which one I've just torn up. My "backup" prop has been on the boat for a few years. can't remember it's number or pitch, but it has some low end grunt with a little top end speed.

My lower pitched acme 911 (10.5į pitch) got reshaped and is still in the box it came in, back from prop guy. Unless you're running stupid weight (nobody does anymore) in a 21' boat with a 350, the first step down in pitch will probably be a dandy.

If you see yourself running your stock bags + PNP + more weight with a crew of 12 at +5000 feet elevation, then get the lowest pitch you can find.

To follow up the earlier question about rpm’s with the 950 OJ. At 5000rpm with two people in the boat and empty ballast it runs around 31.5 mph. 4000 rpm it runs 24-25 mph. 28 mph is around 4400 rpm.

Dang howís fuel consumption? I am on a big lake where we sometimes have to cruise for 25 minutes to get to the riding spot.

ive got a 2017 t23 with the 410, with factory ballast and plug n play 750s in the back and the plug n play bow sac which is 600 i beilieve, i also run a 500 under the seats on the driver side and a 750 filled to whatever it needs to dip that side slightly lower then the drivers side so probably 600-650 and then i throw 2 50lb lead bags on the front seats. we all wakeboard around 22- 23mph and run the acme 2315 prop. its the way to go for heavy weighting, anything else and it would not plane out period. rpms sit just below redline until on plane then settle around 4200ish i believe. if you surf, we havent maxed it out yet and we have had all that wight plus probably 8-10 people.

I’ve never really paid close enough attention to fuel consumption to answer with any specific numbers but I would guess I’m around 5-6 gallons an hour.
What prop are you running? What rpms do you see? What about fuel?

Iím running the 2279. Seems to be the best compromise between weight handling cruising speed and fuel economy. But we donít push crazy weight wakeboarding either.
