I knew I set myself up for that one!, I was cleaning the sbe 2 last night, and it's the same as my browing pump, remove the cap and take the spark plug out, however, once i put it back together, I checked it out and could still only get 2 3-1/2 inch in
there..3rd one just misses it...the 2-3/4, 3" will fit
3 in there...don't know if I should get the extension, heard that it adds more weight but that's not a concern...anyway thanks for the input!!
