Man, the more i hear about them the worst the taste for one i get.
We have been looking at a few but we just can't make the plunge to buy one and i want to be on the river so bad

 

Seado with a rotax. Best combination out there.
I don't know since they have gone to 4stroke.

 

Most of the post so far have been opinions. You need to tell us what you will be using the jetski for, and what conditions it will be used in. I have a FX HO and my buddy has a GTX. I've ridden both alot in different conditions, so i'll give you the pros and cons i've seen.

Yamaha pros: Fuel efficiency, reliability, more hull channels (better in rough water, stays in a straighter line when pulling a skier), N/A (less parts to fail), cheaper maintenence costs, lower idle, 4 cyl.

Yamaha cons: not as fast, not as much fun to mess around on, not many aftermarktet parts

Seadoo pros: More power, faster, does spins easy, more aftermarket parts, electronic safety lanyard, higher resale value, does better at slow speeds (under 5mph)

Seadoo cons: unreliable, high maintenece costs, annoying to ride in rough water, no trim, electornic safetey lanyard


General Idea:
Pulling skiers/family oriented: Yamaha
360's/screwing around: Seadoo

Check out greenhulk.net it has pages of comparisons and pro/cons

 

Well you're post is still an opinion, just like everyone else's. No one is right or wrong, we all like what we like. However, my RXP has adjustable trim. I haven't had ANY problems with it either. It's fine in rough water, I take it out in the ocean quite often, and it handles great. Also, what's wrong with an electronic safety lanyard? I will say the Yamahas are better at pulling people with, however if you got the RXT it'd be a lot better than a RXP for pulling people.

 

yeah, i know my post is still an opinion, but i feel i actually used information that would help him make a choice, instead of just saying "seadoos suck, get a yamaha".

I was going off my buddy's GTX which doesnt have a trim, so i guess some models do? Compared to my FX, his GTX is a PITA to ride in rough water. I constantly feel like im out of control because of how loose it feels, and because it more bounces off waves instead of through them like my FX.

I listed the electronic safety lanyard in both the pros and cons. The system is great, until you have to pay to replace one. All yamahas use the same safety key, but each one has a unique unlock remote (like a keyless entry). If you have a group out on the lake, people with seados will have switch lanyards to ride eachothers ski's, while people with yamaha's can just hop on and go.

 

when i had my XP and was modding it, there were FAR more parts for Kawasaki/Yamaha than there were for my 'Doo, particularly from Riva. Pretty much the only company at the time that made parts for Sea Doo was R&D. My XP was dead on reliable until I started throwing money at it, but I can't blame the ski for that. My biggest gripe with it was it had an exremely high center of gravity with the shock absorber seat and small footprint. cross chop would throw you over the bow at full speed if you weren't careful and even slow maneuvers could be tricky if you didn't know where and when to shift your weight.

 

Just thrwoing this out there but I have 2 honda aquatrax f12 four stroke turbos and they are wicked fast machines! I love then have not had any problems with them and I run them hard all day long and a tank will last probably two outings or more for me. I have had my aquatrax up to 69 on rough water. I cant seem to get any calm water, but it does everyting I could want it to and then some. The turbos spool up very quickly and they scream. I am not saying that one is better then the other just saying that I really think more then anything they way they act is completely up to the driver and how they are going to be using them. No matter which machine you choose you will have fun with them so good luck on you choice just trying to throw another option out there for ya

 

If you can get it up to 69 mph than it's not very rough water !!!

 

True but its not smooth water either. It was to the point were it was like I am surging in the water because my ski keeps leaving the water then when it hit the water again I get a huge surge forward then repeat that process lots of time, then I pulled in behind a boat wake for about 50 feet or so and thats when I really picked up my speed. Them turbos are something else when they spool up at 50 and above they pull hard. I don't know much about the others but I am sure they pull just as hard if not harder. I bought the Aquatrax f12's because I got one hell of a deal on them. Zero hours on the motor and got 2 with trailer for the price of one! So it was a no brainer for me.

 

The yamaha GPR by far has the most aftermarket parts for it. But between the SD RXT and Yam FX HO, the SD has more than tripple the aftermarket parts for it.

Those hondas are super quick. Simple mods can release a lot of power. I was just wondering though, is it your speedo that says 69, or something more accurate like a radar or gps?

 

you cant do 69mph on any jetski in rough water on a gps. Now on the indicated speed maybe.

I havent had a jetski in a couple years but when I did the yamaha GPR1200 was the fastest ski in the world at 80 something mph. This was in 2004-05

 

Yeah, my speedo jumps to 75 in rough water, so that must mean im doing atleast 80

The record is still help by a GPR. Its around 100 with a jetpump, 105ish with a propeller conversion. There are plenty of guys running 75-80+ today with modded skis. Some are swapping RXP engines into their GPR hulls and running over 90

 

i'm sure they do now. i've been out of the game going on 10 years, i'm sure the manufacturers have changed their rules.

if you ever followed any of the 'ski mags, do you remember the Factory Pipe advertisements? /drool

 

Seadoo all the way, we own 2 2007 GTX's. they are great

 

Basically im 17 im out for summer my dad has always talked about getting some, our friends have some and we just started looking for some. Really i just want something i can go out an have fun with and that is fast
