I have a 13 with a 40 Johnson. The motor has a hydraulic tilt mechanism. When I am running full throttle, and I shut off the throttle quickly, the boat veers violently to the right. I have owned other 13 whalers, with smaller motors, and never had this problem. Any ideas on what I should check?

It's you! If your helm is on the starboard side and if you are.....let's say good sized, then that's what it is! By the way, shutting down the throttle at high speed is not a good idea! You may get your back wet!

well put.

You have a trim tab on the engine that is there to COUNTERSTEAR the engines torque. If you shut off the torque the triom tab is doing it's job. Not good for the engine either. Hull could also have some h2o in it that is shifting.

As I stated in my first submission, I have owned other Whalers. I weigh 170 pounds. My six gallon gas tank is in the center-front of the boat and the battery is on the port side. Sometimes a situation warrants the immediate shut-down of the throttle! I am not an not new to boating and I just wondered if anyone has ever had this problem. It is quite un-nerving for this to happen. Thanks for all the replyes.

The helm is mounted on the stbd side to counteract the engines torque to port, quickly shutting down this port torque could cause a veer to stbd due to the weight on the stbd side, on a sensative hull.
I have never run a 13 so it is only speculation but I have never experienced it on a 15 or larger.

Jiles, I've owned a 13'Whaler since 1970 and in that time it's been powered 1st by a 40hp Evinrude then a 40hp Merc. The quicker you shut-down the throttle,the more of a veer will happen due to the above reasons mentioned. To counter this to a degree,,Bigshot's mention of the alignment of the torque stabalizer fin could be a partial solution. Another partial solution is to tighten the steering cables or adjust the hydraulic piston which ever you have. This may minimize the veer. And finally,maybe adjusting your driving habits will go a long way to minimize this concern.(Slowly.....slow down!)
