one advantage if you do leave the prop on and have a large enough tub is when setting up the throttle positions or setting the slow running you get back pressure on the exhaust unlike using a hose pipe ,i have seen loads of people setting up carbs on the hose then when they put the boat in the water the engine cuts out owing to the water pressure on the exhaust , its also its much quieter .
sold my old jet sled and motor and got a call from the new owner, asking if it was a direct drive without a neutrol. Told him yes and the he said that it can sure empty a wheelbarrow fast, probably around two seconds lol. Good thing that he closed the garage door right before he fired it up
