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.pdfHi!
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!!!!
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.
