Steering pull after Solas impeller and fin mods

[garagejetbuilds22]

This is my first post here, but I've been a long-time reader. I recently picked up a 2020 Yamaha 212X from a family friend and upgraded it with Solas impellers and thrust vector fins. It runs like a dream, no cavitation and a solid holeshot, but when I get it on plane, it tends to pull to the right consistently. Both engines are hitting similar RPMs, and I'm seeing a top speed of about 48 mph on calm water.

Has anyone else noticed this after making similar modifications? I'm not using cone rings or wedges yet. I just want to make sure it tracks straight before our next trip to the lake. Thanks for any advice

Did you check if your nozzle alignment is still centered after installing the thrust vector fins? Sometimes even a slight misalignment can cause consistent pull at speed.
