To Nikasil or not, that is the question
After a suggestion from Dave in DE, I began to look for a cylinder exchange for a 2003 XLT 1200.
SBT has one for >$700, which uses a carbon steel liner.
After contacting WSM, I was told that they do not carry a cylinder exchange for the PV 1200, due to the Nikasil plating, They would be more than happy to sell me 3 new cylinders with pistons and PV for roughly $630 a set.
Being the Waverunner is 16 years old, I will likely go the SBT route, but it got me to thinking what the real benefit of the Nikasil coating is in a pwc application.
I understand that the wear rate on a coated cylinder is better, but in the case of a 2 stroke engine is wear the culprit for most engine rebuilds?
In my years of toying with 2 stroke outboard motors, most engines were casualties of oil starvation or poor fuel long before they were worn out.
From what little I have had time to research, it seems as though an engine like the PV 1200 has a realistic life expectancy of 300 hours. If this is true what could one expect to get out of a carbon steel sleeved engine?
It doesn't seems as though these engines turn a very high rpm , so is heat transfer a true concern when going with a steel sleeve?
I'd love to hear input on why one had chosen to go one way or the other.
Either way this is most likely just rambling at the moment as I still need to pull my engine to be sure of the integrity of the bottom end.
