Oil tank leaking

[Eugene]

On both of my Sea Doos (97 GTX and 2000 RX) the oil tanks are leaking looks like from the seam between top and a bottom.
Any idea how can I fix it?
Thanks.

The safest thing is to replace the tank.

Well... On both skies... In a worst case the oil won't drain completely, only to the half of the tank.
Is there anything else I can do? Like put some glue, sealler, or gasket maker? If Yes, what kind?
Thank you.

Epoxy for plastic would be my best suggestion.

[Eugene]

OK. Thank you very mach.

Re-glue it ( Hobby shop glue) Or you can spend $65.00 at Sea Doo for a new tank which takes 20 minutes to replace. That is alot less messy than pre-mixing and a hell of alot move convient when you pull up to a gas pump.

This habit of telling everyone to pre-mix is stupid old school thinking, IMO. Oil injection is cool, unless you own a race boat.. I even ran oil injection on a few of my racing boats that won championships.

Did you know that Mel Miller's 1995 XP 800, bored and stroked to 1165cc nitrious oxcide 82 MPH Sea Doo had oil injection ? It turned 8200+ rpm and never had an oil injection pump failure or an oil related engine problem in the 4 years that we ran that boat. His current ride is a 74mph 1998XP and has oil injection too. It makes 217 hp from a 1050cc motor. No oil related problems there either. Removing oil injection is unnessary and dumb, IMO.

I have two skis with the same problem - leaking oil tank. I will try to glue them first using epoxy resin.
About premixing. I just bought my jet skies, so I'll keep oil pump for now and may be premix just a little, like 1:100, just in case, until I am sure everything is OK.
What do you think?

[Bill O'Neal2]

I think you do not need to pre-mix at 100-1 or any other ratio if you have oil injection.

Well I guess i seem to think that is the best route cause i have a 99 GTX and had the oil pump fail twice in which cost a rebuild both times!!

I raced motorcross for years premix is in my blood and unless your leaving your ski at a marina or you gas up dockside it really doesnt take too much more work for the amount of money a seized engine costs to premix at the pump and how many factory racing 2 stroke engines do you see with a oil injector in motorcross 0.

And I'll counter that with, in the last 15 years of working on Rotax engines I have seen maybe 4 to 5 oil injector failures in skis that are maintained properly.
Of those 4-5 failures, all but one was a cable or cable wheel failure, or the screws came loose for the cable bracket, all of which were preventable with proper maintence.

Sea Doo's use the same Mikuni pumps used by Rotax in there airplane and sled motors. In the airplane engines, it is mandatory that they perform for hundreds of hours and sleds turn rpm in excess of 8500rpm. There is no reason other than sloppy maintence for a oil pump failure.

I appreciate your opinion. I hope you can appreciate mine too. Not all people will put up with pre-mixing or the chance that family members and others will not forget the oil in the gasoline. Most PWC users are accustom to oil injection and are clueless when it comes to pre-mixing.

I'm not sure why, but PWC owners are the worst when it comes to following directions about greasing driveshafts, trailer bearings, charging batteries, ect.

[Eugene]

I like it.
Could you tell me, what included in a "proper maintence"? I have a 97 GTX and 2000 RX.
Thanks.

I would purchase the block off kit from SBT and eliminate the oil injector cause ive seen this before and it sure makes a nasty mess in the hull..

[DaWrench]

well the one im repairing now it started with a cracked tank the owner didnt repair cause it would never run totally out. He went on vacation took the ski and what do you know the hose that supplys the oil injector either clogged or cracked it overheated blew the headgasket water entered the head and siezed the engine. Some repairs are situational being that different things work better for different people and I totally understand and respect what your saying. Ive seen many customers who didnt even know you had to add oil. they bring their ski in and say somethings wrong and I know this sounds funny but the first question I ask a new customer " Did You Have Oil and If You Did What Kind " the answer " What Do You Mean " LMAO I just want to know whos giving all this money to these people!!! :D

"Proper Maintence" means either spending the money to buy a real OEM service manual, reading it from cover to cover, especially the section on maintence, then doing what it tells you to do.
Besides that, as stated in the owners manuals, it says to lift the seat or the hood and do a visual inspection each and everytime you ride your PWC. The visual inspection includes cables, hoses and clamps, smelling for fuel vapors and generally looking for such things as leaking rave valves, exhaust manifold leak stains and anything else that may be out of place or not up to snuff. As I've mentioned many times here, and is written in all the manuals, such things as charging the batteries and greasing the pto and/or driveshaft bearings AFTER each trip to the lake.
Or, as most people do, take it to a professional shop and have this done at least twice a season, especially before you lock it up for the winter with water in the exhaust system.

It amazes me that more DYI'ers do not buy servce manuals. They pay for themselves with one repair or service, mainly because they make it harder to screw up the job at hand.

There is an ad on this website in the PARTS FOR SALE forum for cheap repair CD's for most models of SD watercraft. Although I perfer the hard copy manual, the CD is better than nothing and well worth the money.

We can help and guide you on these forums, but there is nothing like the pictures and the written directions that an OEM manual provides. Having a manual when you sell the PWC tells the next buyer that you were serious about maintence and he will be more apt to give you what you want for your ski.

I would recommend buying a manual especially the hard copy cause you can take it with you every where you go. I buy manuals for everything (cars,motorcycles,boats) it really make things easier when you have details and instruction.
