I have a 2510 with twin 150s , sense I have owned the boat I could slowly turn the wheel usually to port and not have the engines move then if I gave the wheel a quick jerk it would start to turn .
I installed a new helm that did not help , I talked to sea star they said no problem you must have gotten a faulty helm and the replaced it again .
It still did not help the problem , I had sea star on the phone we did some testing of the rear ram and the tech felt the ram was ok and I must have another problem .
I repowered and when the engines were being put on I asked to make sure the toe was correct because I was having a steering problem . No change
Finally this summer we stuck something offshore it broke off the skegs right at the bullets and my steering ram was now leaking so new lowers and a new steering ram .
I was not even out of the no wake and I could tell the steering problem was fixed, boat goes dead straight no correcting much more responsive . I think I had a slight leak and when I was under way with more pressure on the seal it would leak fluid from one side to the other , it only took 4 year to figure out
