Steve, you statement ” arguably best engine for a bass boat ever made” is certainly a matter of opinion. I don’t know if you’re old enough to remember several years back and the Opti is certainly one of the best, but as to the best, it was hard to beat the old 4cylinder 90 degree V’s from OMC. These included the 115, the 135 and the 140. Another one to give the Opti a run for the money is the 2.5 Mercury, either in a 135, 150 (workhorse for years) and 175. I do agree with you that shying away from the 3.0 Mercury because the new 4 strokes are out doesn’t make sense.
BTW, I run a 3.0 225 on my Puma and it does really well
