Yes they have that advantage for sure..you also need either a huge pump OR more RPM on a smaller pump. 99% of jet boats in NA run Mercury Sportjets 200hp,400lb or v8@ 300hp/300tq,650-800lb... the Sportjets are what most smaller or shallow water boats want because they can drag the boat off the rocks when need be, v8s are to heavy and it's NOT fun....this is where the 4g63 shines...v8 power in sportjet weight
