Hi!
Here is my questions: 1) How hard is it to switch engines 2)What is wrong with my engine 3)Why do I see salt water inside cylinders? 4)What to do?
THANKS IN ADVANCE!!!!
1. Well, its not too hard, but you may need a hoist and a moderate amount of mechanical skills and tools. Here is the installation guide from SBT to give you an idea: http://www.shopsbt.com/pdfs/y1200pv.pdf
2. My guess is the the #3 cylinder was going bad as soon as you noticed the power loss to 40 mph. You were running on 2 cylinders. You probably should have checked the compression then, and it would have given you a clue. It may have been a simple cylinder rebuild at that point. #3 cylinder could have dropped a power valve, oil line came off, etc..
3. Hard to know for certain the cause of failure at this point, but continued running the ski probably resulted in a rod from this cylinder going through the inside of the crankcase someplace resulting in the water in the engine.
4. With the salt water issue, I don't think rebuilding the engine is an option. Its either a new engine or a new ski. I think SBT requires an intact core for the engine.

Good Luck

Thanks for fast reply!
Will I be able to see if something is wrong with the core if I will take the engine out of the ski? In other words is it possible to see if it is good or not to send it to SBT?
Yea, once you get the engine out and the top end off you will be able to see the damage.

1. Depends on the kit. You will have to check. Some kits come with everything you need for 3 carbs. $50 sounds like a 1 carb kit.
2. I recommend original parts.
3. I think it is really hard to tell if the needle or seat is bad. Some claim that you can see wear on the end of the needle, but you could have a good needle and a defective seat and never see the problem. I'd get a needle/seat kit while you are at if for each carb. They are not very expensive.
4. Don't know on the intake.
