Surface Piercing Drives

Source of the post Had a customer with triple Arneson surface drives. I got to work on them. Definitely a whole new ball game. You learn a lot about them when the customer nearly rips them off after hitting bottoms $$$. Loved doing the sea trials after repairs.

Would love to have seen/worked on those. Lucky you.

PV has SSM drives with surface props.
Three blades - provides a higher top end speed since only about two blades are creating drag.
Four blades would get me a better holeshot but I'd lose 4-5mph on the top end because of the extra drag of almost 3 blades in the water all the time.

Ya the fun was good while it lasted. The last time I worked on it was two years ago, then the boat ended up being sold to a guy south of the boarder soon after. Haven't seen another one in the area since.

Some of the bigger 100mph+ boats up our way run the Aronson drives. Those blades are razor sharp.
