1979 Evinrude Drill Exhuast

[skeeter91]

yes,i did mine with lower removed.not sayn' you HAVE to do it that way,but its alot easier that way to keep the holes in line.the hole saw way with the plugs works well too,just a manner of how much louder you want it.i will post pics when i get home this afternoon.

So I have 2 options examples so far

2 1.75" holes made with a hole saw

4 0.5" Holes I assume just made with a 1/2" Bit.

If I could get some more pics that would be great. Looking at doing this soon. I have the tools for both options. Those freeze plugs seem like an easy solution

Probably going to do 2 1.5" holes
