Engine Size + Hull Recommendation for a 6'4" 225lb male??

[skywalka]

Fairly new here. Have been looking into purchasing a backflip/freestyle ski. I ride on a flat water lake with no wake at all.

I'm looking around and pricing some skis out, but am unsure of what engine size/brand I should be looking for. Is a 900 enough power to learn on and can do backflips (with the correct technique of course)... or will I outgrow that quickly or struggle to flip it, given my size? Is a 1200 way overkill for a hobby rider? Which brand engines should i consider vs avoid? I've heard of DASA, XScream, and Bun. What is the best overall value for your money? Any hull recommendations for a larger rider? I'm going into this knowing that the build will be costly.

Thank you everyone.. Looking forward to your thoughts!

I'd be hitting up @Jr. LPW for a
Php 1015, tpe 1021, or tpe1105. There's a guy that rides a tigercraft flatwater hull, dude is I believe 300 LBs and idle flips his 1105. Tpe 1021 is kinda nice because the shorter stroke means less stress on components and you get more time between rebuilds. My buddy has one with a standard weight crank and ive ridden it, definitely more power than my php898. Also @DAG has an 1105 for sale...

There is potential with a 900 too, especially if youre ok with running race gas. At 215, 5 10 just learning combos I was doing 3 in a row with a pump gas php898 in a hybrid layup hull, oem 155 pump. I'm a bit biased but with an 89mm bore and +4mm stroke it lasts a long time between rebuilds and is Uber reliable. That's through LPW/JR now too.

got it- thank you!! So i'd probably want to be around 1100cc to be safe?

Any of the motors I mentioned would be awesome for you. Dasa, unless ninja or other builder ported are relatively tame. XS is a great option too. They make a 1060. There's guys with race gas 898s doing 10 flips in a row in carbon hulls.
If you're OK compromising some reliability for power go with the +10mm stroke.
If I were to upgrade motors I'd probably go with the 1105. But the reliability of the 898 just can't be beat(if you search around here you'll find php has a pretty religious following, for good reason!)

Great! Is there a way to message privately on here or only on threads? not sure entirely how the site works... also, what would be your thoughts on a XS900? total beginner - will this be enough power with a carbon bun exhaust?

in a Revolver XL hull

Bigger is generally better but, do you have someone that can tune your carbs and pump?? If not you will spend your first season learning how to do that.

Yes - i have someone that would build the ski for me and do all of that prior to me taking delivery of it.

Xs900rr +10mil?
Idk about with the carbon wet exhaust. Xs sets them up with dry power factors. Follow a builders recipe is your best bet. I've ridden a 900rr on race gas tuned by a pro and it was plenty of power.

I believe it's this engine. http://www.teamxscream.com/products/index.php?main_page=product_info&products_id=6535

I have a full spec build sheet i can send if you would like to take a look. I was under the impression the carbon bun would provide more power.

Stock stroke 900 is going to leave a lot on the table. Not even close to the amount of power a stroker will give you.
I can't comment personally on the bun pipe but I would go with what your engine builder suggests. They know what works best.

Okay, got it. Thank you! I'll check out those other engines. If you're able to and the site allows direct messages or chats, please message me and i can send you the quote i got. I'd love to hear your thoughts. Thank you for the help!

"What are you riding now?" "I ride on a flat water lake with no wake at all." So which is it?

i have a sit down ski that i ride on a flat water lake.

If you've never ridden a standup, a big engine in a light hull is going to control you, not the other way around.

You need some tray time on a non flip ski first otherwise you're just gonna hurt yourself, or better yet sink said flip ski. Most all flip skis do not have bilge pumps or foam in the tray. They do not like sitting in thr water for long periods of time, they will take on water and will absolutely sink with someone that is learning to ride it. They use scuppers and one way valves to remove any water in the engine compartment but only work when the ski is moving so if you're sitting there trying to board it on deep water, and struggling, you will take on a lot of water. Best to start with something like a superjet and work your way into a flip ski

Scuppers are for expert riders or anyone who likes to tell stories of losing their ski. Use a bigger battery and a pump or ride in shallow water.
