89 200hp spark plugs

[Jons69chevy]

Hello All. I have an 89 evinrude 200xp running premix fuel. The clymer manual lists 2 different spark plugs-ql77jc4 and another that is a gapless plug. It says that the gapless plug is for sustained high speed use. Which plug is going to be the best bet for a bass boat? Thanks in advance....Jon

When you see the price difference between the two, you will have an easier time deciding which one...
