So, what was wrong with yours that was hiding behind good compression? Bad crank? Bad seals? Loose motor mounts?
Moot, do you know where you read that? I have looked and cannot seem to find any "hard" number like that.
Actually I believe the motor itself is fine but I have been through the carbs twice and still chasing a hesitation issue. I also had to replace a wheel bearing on the trailer.
There are many factors to these things that cannot be found by just testing the compression and listening to the motor run on the trailer. Thats all I was trying to say.

yeah there are two types, Direct injected and fuel injected..............either way they are still touchy. your bascially taking the tempermentalness of a two stroker and poking it with a cattle prod..............if you want a GTX , get one of the 96 / 97s with the 787cc Carbureted engine. I have one, and once you have it dialed in , maybe even slap on a performance grate (i did) you have a hell of a 3 seater that can tow, without all the hastle of the RFI/DIs

97 GTI would be the same hull as the 96-97 GTX with the 718 single carb engine in it. on all rotax 800/787, 720/718, 657/657x, and 580 perfect compression is 150psi. 130 is acceptable, but will need a top end "soon". for the 951 motor, 130-135psi is considered "perfect" and 120 is rebuild time. for any readings that are not the same, the compression numbers should be within 5-10% of each other.

On the 717, 720 motor the target is 150 psi on both cylinders and within 10% of each other. 135-150 means wear and a rebuild coming soon and I say, unless you're getting a steal, 130 is close to shot. It will run, but much slower than a fresh one.
My dream-o-meter says I can hit 50mph with good compression. These don't have the hole shot, jumping or eye peeling top end of the bigger motors but they are still fun to ride. I love being out on the water, so almost anything with a little pep would work for me.
You are right, but he seemed intent on buying so I was just hoping he would at least check that.
You got 5 mph on me with your couch...not a big jump up there, but yeah, for the same money I'd get the GTX.

A GTI is not slow, it's just not as fast as some of the other ski's. I have a 96GTI, it will run 50mph indicated, 47mhp on the GPS, all day. While the extra HP of a 787, 25 more HP, is nice there's nothing like the reliability of a 720, it's damn near bullet proof.

Hi neighbor. I am also a relocated Cleveland boy (actually Medina) up in Michigan now, and 3 years on the water here in michigan (I grew up on lake erie and west branch in Ravenna), one thing I will tell you is that I would use great caution buying a ski in Michigan. I know I will offend some, but they drive jet skis just like they drive cars here, hell with the rules, logic or capability of the ski. Combine that with the shallow lakes around us, it is a bad combination. There are a crap load of them for sale now and everyone is trying to get rid of them so they don't have to winterize them. I would keep looking and increase your range of look, I think even $3500 it is a bad deal unless both of them have low hours and have been absolutely babied. I ended up buying mine of a friend in Nevada and trucking it home, it was the best deal compared to what was around me, and I knew the history of the ski since it was born...
Just my 2 cents.

You just want to make sure that you are careful with your inspections and water tests. I have looked at a few already recently that I had to pass on because of many different types of things. One thing that I have learned from this community is to check everything and do not be impatient. I really do not think it is an "only Michigan thing" but you get this all over the country, buyer beware is the stance that should always be taken no matter how nice the person is, etc.
Lots of people try to unload their junk onto other people. One thing you do want to keep in mind is most people who own skis are not very knowledgeable on them. He may say they run well, for him they may, but to someone who knows that to look for, hear for it may be a different story. That price in my opinion is way too high for those skis (I am pretty sure I have seen the pics on Craigslist). I would not pay more than 2k for those with the trailer, maybe a little more but not much. Keep in mind if the owner has never replaced the fuel lines, carb rebuild, etc you will have to do that. Also like mentioned before most people are selling so they do not have to winterize their skis. You can do it yourself obviously but it is more money that will need to be pumped into them. Use that to your advantage as a negotiating point.
I am in the same boat as you (pun intended). I have been looking the last 3 mths for my first ski, and if I have to wait till spring so be it.

Yeah, $3500 is pretty high considering the compression numbers, but take your own gauge with you if you look at them. He may be doing it wrong and his gauge could be off. 3 seaters, regardless of the hp command a better resale for some reason so expect to pay more than the xp pricing on these. I think if you check them over and like what you see, see how firm his price is and don't be afraid to shoot pretty low at first. I paid way too much for mine given the amount of work they needed. I'd like to get what he is asking, but I know realistically the chance of that is slim. Good luck

Well guys I am now the proud new owner of a 2001 Sea Doo GTX! I ended up taking it to the dealer to have them check every detail over and it came back all looking good. Compression had only dropped 5 PSI on both cylinders since new and everything else looked good. PO Even replaced the missing bolts on the intake grill replaced, apparently this is a known issue on this model as the dealer said he sees it often. Taking it to the lake next good day I can! Thank you so much to all the members on here who helped me with my research!
