Offset Low Water Pickup Holes in Nosecone
Anyone seen this sort of thing before? Is this designed to create a “drag bias” on one side of the nosecone to help offset the torque of the propeller? This unit has a torque tab as well, although it’s not bent as much as the typical torque tab, so I’m wondering if this water pickup offset helps offset the torque??

I believe that to be an Allison modification. Show a pic of the skeg cuz the Ally mod involves the skeg also.

Not buying any drag "bias change" for torque reduction. I saw no change in my testing. Titus used to do several different intake configurations and I'm sure others did as well. I have the starboard hole in my Sporty plugged, it increased speed .7 MPH. But I would only do it in a motor that makes tons of water pressure.

I purchased a sportmaster from a friend because he said the motor would get hot. He had been using it on his Ally when it was stock and it worked fine. Motor is a 15" 200xs ros. After modifications the hot issue appeared. I bought it cuz I needed a 15" lower and figured I could make it work. Turned out he had a 1/2" water tube. I changed over to the 3/4" I have always ran and it has never failed me. Had lower on several STVs and a couple Allisons. As far as the mods go I could not tell you if it made any difference or not. My guess is their blocked hole was to make the supply to the prop cleaner. I think the 3/4" tube is necessary with only 2 holes.

I was told it gives cleaner water to the starboard side for the prop.
