my 05 enzo 230 ran straight as an arrow last year. over the winter I installed a heater. the old steering cable did not feel that bad to me but I figured while I was in the area I would replace it.
the new cable is so much better, super light. sounds good but the first time I ran the boat I had a abrupt pull to the starboard. I let go of the wheel and it turns a good half to 3/4 turn. so I did some reading on rudder tuning. although it seems weird that all of a sudden it would be this far off it is the only thing I could find.
let me start by saying you can learn to do almost anything online if you spend some time searching. I say almost because I just cant find much on rudder tuning other than if it pulls right file some of the trailing edge on the left or vise versa. also to do a little at a time.
anyone with experience please help. I have pulled the boat 4 times and it does not seem to be getting any better. I understand it is hard to say how much to take off because it would depend on the amount of pull but even a good starting point would help.
I filed off what I would say to be about 1/16 on the port trailing edge and it seemed to be maybe 30% better but still really bad so I filed off another 1/16 and it seemed the same. so I had read that if you file on the leading edge of the starboard side it would make a major adjustment so I filed 1/16 off the leading starboard and 1/16 more off the port, now it seems to be back to where I started.
I am filing starting at the trailing edge the whole length of the rudder and about 2 inches in from the trailing edge. i'm filing the trailing edge so that it has a nice smooth rounded trailing edge like the factory.
i'm about ready to take a grinder to it and grind 1/2 inch off.
please do not respond with "take it to a experienced tuner" I live off of lake Erie and I have only seen 3 other inboards on the lake and I really do not believe any of the mechanics in this area would know what they are doing.
also don't say "go buy a tunable rudder" I know this is an option but really do not want to go that rout unless I have to.
