While on a hunt, I had a friend pull up behind me and tell me I was leaking oil. It was leaking bad. I turned off the engine (which sounded fine) and started looking around. I had a hole in my Crankcase about the size of a pencil. I have aluminum skid plates and no major dings below hole. after dropping skid plate and cleaning, looks like the hole came from the inside out. Took it to a new AC Dealership in Reno. They are trying to sell me a new engine for $2500, $3200 installed. They didn't even want to break down the Engine. I called Country Cat service dept. and a mechanic told me it could be the secondary gear in the tranny. Any help would be appreciated on me tearing it apart. Never worked on a 4 stroke. Dn loading service manual now.
