Anyone ever mess around w/ shaving one side of the rudder to load the steering, = no slack @ the wheel when pulling a slalom course ? ('95 190/265 tbi/powerslot/13-18 4 blade OJ)

Sounds like somebody shaved your rudder to take the preload out of it, which a few here have done.

Ok,it's called preload (I'm kinda new to all this) anyway, no, I wan't to add more preload,which I've been told is done by filing a 45 deg bevel to the trailing edge of the RH side of the rudder (The rudder is untouched & pure @ this point)

Yes. Here's a post with a pic of what one looks like from the factory.

Here is what the rudder on my '97 190 looks like after I shaved it quite a bit. I have a pretty heavy load on mine. Just get out the file and file a bevel, test and repeat until you are happy. Easy to do.

What they said...
Just wanted to let you know that your engine is rated at 275 hp not 265.
You just picked up 10 free hp!!!;)

If you were to shave the rudder....could you then shave the other side to make it neutral again? I'm serious.

I figured as much. I thought about shaving the rudder on mine, but decided not to for when the wife is driving.

Huh,the amount of material taken off doesn't look that significant,so I guess it's like you guys said,go easy.Thanks everyone,& thanks for the free 10 hp!!

take just a small amount off the rudder at a time to be sure you like it. It's really hard to but the brass back after it's been ground away

Actually ,your wife may like it better.
Especially when pulling you in the course at 39 off...
:D

She isn't brave enough to drive the course. In her defense it is a fairly short setup. I hope to get her driving the course at another lake this summer which has unlimited setup.

My concern is her or some of my more novice friends driving when not in the course. And havingthe boat turn suddenly if they aren't holding the wheel somewhat tight.

You are correct. It is not a lot of material. That being said it does take a bit of work to shave the rudder with a flat file (how I did mine). I wouldn't take a grinder to it. Just take a bit of material off and test. As said above if you happen to get a bit too much pull you can always take just a bit off of the opposite side.

Here is a pic of my old rudder, it had what I would call an aggressive load on it. I am not a course skier... My new rudder has about 1/4 to 1/3 as much material removed and I feel it is better for the amount of open water skiing I do. These boats don't feel right with a neutral rudder, but a little loading of the rudder makes it feel more responsive.
