TillerPilot Installation
I saw the photos that have been posted in this thread and just thought I'd add my thoughts about installation. According to the installation instructions, it is recommended that the attachment point on the tiller be about 18" ahead of the rudder post/pivot point for optimum performance. If installed farther forward the unit will require less force to move the tiller but will have to move farther (resulting in slower response time) for a given amount of correction. Mounting the attachment closer to the rudder post will result in faster correction time but will require the unit to work harder due to the reduced leverage. Of course some consideration must be given to ergonomics so it might be necessary to deviate a little from the 18" recommended on some boats.
I mounted a Simrad TP20 on my E27 by epoxying the mounting sleeve into the starboard cockpit seat 23.5 inches outboard of the centerline of the boat (as recommended) and 18" forward of the rudderpost. I epoxied the mounting pin into the top of the tiller 18" forward of the rudder post. These positions eliminated the need for a mounting bracket on the outboard end or extensions on the shaft end. This configuration also, happily, resulted in the unit's shaft intersecting the tiller at a height that makes the tillerpilot horizontal when the tiller is at its lowest position - perfect!
The other imperative is to install the wiring connector where it will not be tripped over or ripped out while you are working the boat. I mounted mine on the vertical face of the starboard cockpit seat, directly below the tillerpilot and keep the slack tied up off the deck with a velcro strap.
The TP20 may be more powerful than absolutely necessary for the E27 but I decided that more is almost always better than too little, especially given the E27's hard tiller pull under power. I also wanted to be able to interface with my GPS on longer passages, which you can't do with the smaller units. As to not having a display on the Simrad, I have never missed having one at all and the price was right!
A tillerpilot is the best money I have ever invested in a boat, especially since I singlehand a lot!
