Canvas and a few othe Questions

Hello,
Wow, I finally found a web site for my boat. I have a 1989 V20 that I've owned since new. I have beat that hell out of this boat and want to get it back in shape. I originally had a 225 Yamaha on it, but then repowered it with a 200 Yamaha in 1999. It is so much slower now, has anyone used a jacking plate with any success?

Is there anywhere I can buy a ready to go replacement canvas for the original hardware or am I better off having a custom top made?

The steering has always given me problems, has anyone converted to hydraulic, is it expensive to do so?

I am also looking to get a new trailer for it, any suggestions?

Thanks,
Broc
