New owner of 2015 427 Ss Ls3 winterization ?

Recommended Posts

I’ve just recently purchased a 2015 23lsv with the 450 hp Ls3. It says 427 Ss on the engine (not sure what that’s about cause it’s not a ls7). Partial closed cooling.

Anyways we ran into a nice day yesterday and wanted to try out the new to us boat. I’m going through the process of putting everything back together. I put the manifold and trans cooler hoses back on and reinstalled the heat exchanger end caps along with the the impeller access cover and v drive plug. I was left with a large (2” diameter) o-ring. Where on earth could this go? Needless to see I missed the opportunity to try out the new to us boat.

Not completely familiar with that motor, but most raw water pumps have an o-ring that fits in a groove underneath the impeller cover.

Many replacement impellers come with an O ring that is not used in most Malibu pumps. Just use the white gasket and discard the O ring.
