115 yamaha powerheads

[waterman]

I am trying to find out if there are any differences in a yamaha 115 2 stroke powerhead made in 2003 and one made in 2004/2005.I have chance to get a good used one to replace my blown 2003 one, but I need to be sure it will work.Also what is a 115C? The "C" is what I'm not sure about.Thanks for any assistance. Waterman

The 2003-2006 powerheads are the same. A C115 is a non oil injection model, but not sure about a 115C.
