# 4 and the last one are Quadras, a 35cc and 75cc. The 75 is a real powerhouse and will swing a 24X10. The 35 is pretty goggy. The engines with CNC cases are A&M Sachs based engines. The first I think is a BME44.
That looks like an old Quadra conversion which is not as powerful as the 75XL or the mag 75. It still packs a punch though.
So this would be a 75? A 24" prop is in order with this one?
