Necessary to dry start after being on water all day?

Thanks for the fogging explanation. Do you shoot the stuff in the carbs or in the cylinders? I saw both answers on this thread.

As for the buoy, yes, I usually leave it there floating and I cover it when it is going to rain. I have found this sea-doo to be very watertight and I never had any issues with it (including previous owner who lives a couple of cottages past mine). If I leave for a few days, someone is watching for me (my uncle). The problem is that my own beach is too rocky and that I have no help taking it out of the water (my uncle is 80+ years and a Sea-Doo is heavy).

I wish I had a better way to park it such as a boat lift or one of these floating sea-doo docks (like a mattress but modular that can be taken apart) but for that I need a dock. First, I had to rebuild my stairway to get to the water and next year hopefully I will have the money to put a dock. I just bought my dad's cottage and money has been flying out of my pocket in the six figures since last year...

As you may be aware, summers are short here. I expect do to some riding in the next two weeks and a bit of riding in September but my ski will definitely out of the water when I leave during the week when August ends. And I may take my ski to lake Champlain in NY state this weekend to ride with a friend who has a boat! As far as I am around, I am not too concerned sinking this sea-doo. It just never cross my mind that it could sink!

Have it running with the top of the air box off. Spray it right into the flame arrestor screen about where the carb barrel is at. The engine should start to stumble / die. Shut it off. Do not run more then about 30 seconds. Then I remove the spark plugs and put wires on the grounding posts on coil housing. Spray fogging oil in spark plug hole while cranking engine with the starter. Then do to other one. Put spark plugs back in, wires back on. I put Dielectric (tune up) grease inside the spark plug boots. It makes the boots easier to take off plugs and seals out moisture and electrical voltage leakage. You can find shop / repair manuals for Sea Doo's on the Internet for free down load. You have no launch ramps close to you? I would never be comfortable leaving my Ski floating somewhere. Do not worry about asking questions. We are brothers here.

If you are going to dry run it to blow out water, I suggest waiting until the engine cools down. The 951 likes to run away if it's hot then run without load... It shouldn't occur. But it's less likely with a cold engine.

Good to know. What does run away look like on a 2 stroke?

I have the temperature sensor now, so that I should be able to know when it is cold. LOL.

Famous last words. No one ever has issues until they do. Things wear out. Something will eventually leak.

Not really, just sink two 3" Galvanized pipes to secure it to for now. Or if you really want to go cheap and easy, anchor with 50 lb bags of sand.

Run aways can not be turned off hot spots act as spark and the engine will run until it seases up sometimes spectacularly.

Once you stop crapping yourself when it runs away then just pull the choke. It will kill it fast.

A run away is when the engine is hot enough and the fuel mixture is lean enough that is doesn't need a spark to run.

So, when you have a run away you WILL know it as the engine will start then rev to wide open throttle by itself and the lanyard and stop button do nothing. The only thing you can do is either pull the choke and kill if or wait for it to blow. I suggest pulling the choke.

Thank you for elaberating, elaberating, motors in general can do this and some times they don't have chokes.

This typically happens on older two strokes and especially skis when they are started out of the water as there is no load on them. Then be fine when in the water. If you don't have a choke then you can try getting it back in the water, dumping fuel in the carbs or if you have a primer pump the crap out of it. You can shut the fuel off but it might seize and you can try pulling full throttle to add more fuel but might not help.

When I start a new engine or new to me ski without a choke I always have the air filter off and a jug of fuel ready to flood out a run away.
 
Like he said chokes or suficate it no air no run. I'm done sorry to rabbit trail.

It's never good rule to add more combustible to a fire take away fuel or air smother or suffocate. Will flooding work yes. But if anything goes wrong that extra fuel get you burnt.

Pull the choke to stop the lean runaway. And that's a good reason not to defeat the choke, make sure it's working and adjusted properly. WOT might work as well (to create a lean out).

I guess your 2-stroke would exhibit characteristics of being too lean before runaway actually occurs, if you're listening carefully.
 
To come back on the issue of a boat lift, I really wish I had one. Hopefully next year. Yes, I have access to a boat ramp and even better, my uncle who lives three houses down from me has his own descent and I can retrieve my Sea-Doo there with my ATV (slow slope ATV powerful enough).

Unfortunately, three houses down, that slow slope is turning to a 50 feet high cliff... And on the lake, I only have 15 feet wide of land with a gigantic tree on it leaving just enough space for a 3-foot stairway. Any dock I will put there will have to be very light and easy to slide on the stairs or be transported at the top of my stairway where I have more room. And as I mentioned, money is tight because I just paid cash for the cottage.

So it is either the buoy or beaching the ski and my shore is pretty rocky. I do have a wooden shape to pull it on but all by myself I am not strong enough. And my uncle is over 80 years of age and I have no kids and my wife is disabled... So it would be really tedious asking for help every night to lift the Sea-doo out of the water and it would not be nice to my uncle's land to get to the beach with ATV and trailer just almost every sunny day.

So for the moment, I made the buoy choice and parked the ski at my uncle's in the water so we can have an eye on it every day. Next year, I hope to have the budget to arrange something nice at my place but I know it will be another 2-3k$...

Summer is almost over here...

Benji, if you want to oil your motor to avoid corrosion assuming you won't be using your ski for more than a couple days but still leave it in the water, you could remove the spark plugs and squirt some in, rotate a couple revolutions by hand and re-insert the plugs. The most common problem with leaving one of these in the water for days is they can sink, flooding the engine and electronics with water. Having shore power for a battery maintainer along with installing a 12v bilge pump, might be an alternative that works in your case.

BTW, the last part I do in the spring before 1st startup, remove plugs and rotate by hand a couple revolutions while listening and feeling for scraping sounds or tight spots caused by corrosion. While the plugs are out I squirt a little oil in and rotate it again a couple of revolutions ready for an oiled 1st restart of the season. Once started, I might change the plugs to new ones, depending on if they're well used already from the previous year.

Riding a sea-doo is wild and cool! At 51 years old, I wouldn't have dreamed of that when I was 14 (in 1978...). But today, I am wondering if it was a good thing to buy one. By looking at this forum, I only see problems, problems, problems... My worry today (as it is pouring outside) is not being afraid of corrosion but too much oil in my ski!!!! See my other post: how to siphon gas!

And yes, my sea-doo is at the buoy and covered. I am not the least worried as this ski seems to be very sealed: never saw any significant water inside. I can drain it with a cloth and three good squeezes! And in two months, we will see our first snowflakes...

And, speaking about how the purpose of this forum is to educate, I have a related question to this thread.

After trailering to the ramp, start it dry briefly or wait til it's in the water? I've been a boat guy and running the engine without water running through the cooling system is a big time no no. What about skis?

Peter
 
I suppose that is a 2 headed answer as well. First off, when you start a ski out of water there is no water flowing through the ride plate so it can damage seals... But it is fine for less than a minute. I always start mine before I am in the water for a few seconds and then turn them off just because I don't want to be the guy in everyone's way fiddling with my ski on the ramp when it won't start. Basically it allows time to discover a problem before you are on the ramp. I have seen people start the skis and leave them running while they back in and this I would avoid.

not sure if this helps or not but thus is my setup, very cheap and not extremely heavy. Leave the ski on the ramp at you uncles beach.

There are beach carts out there too. Big wheels easy to roll. Most people load on a trailer and park at their place. There is no launch ramp near you? Not criticizing you, just thinking through issues.
