Just remember that though bollard testing is a good component of your investigation that strong pull in a bollard test doesn't directly relate to top end speed. You can have an engine prop combination that pulls less on the bollard test but that gets more high end speed. Speed range has more to do with the prop than the engine. However even this isn't absolute.. You truly need to match the engine/motor to the prop to get best efficiency/speed. Mismatched engine/motor/prop combinations will eat power, cause fuel consumption to skyrocket and reduce engine/motor life.
