Our 60 degree, or properly named "Eagle Series" motors are lower compression. The one in the pictures appears to be a 90 degree cross flow which can have upwards of 140. The 60 deg 175 has different carbs and porting, not sure on compression numbers. The 60's also use o-rings for head gaskets. If you pull the heads, make sure to apply sealer to the bolts and a thin ring of sealer around the water ports making sure to keep it out of them.

Red...my 225 is a 90 degree V6 Looper
