The tiller drive unit itself is removable and is the only thing exposed to the weather, except the control head. A pin is installed in the tiller and one on the cockpit coaming ... with various mounting options (extra brackets) available to get the alignment correct. A power plug is installed in the coaming. I don’t suspect mounting or removal is any harder than the all-in-one units. The rest of the SPX series or EV100 series autopilot consists of a control head mounted in the cockpit and a course computer and a fluxgate compass (both mounted below decks). With this setup, the only thing that differentiates a cockpit wheel drive vs. cockpit tiller drive autopilot is the drive unit itself.
The current P70 control head will work with both the current EV100 and the older SPX series ... for the older SPX series there is also the ST70 or ST70+ and ST6002, ST7002 or ST8002 units that were used. It’s probably a more robust unit than previous versions that had all the ‘brain’ in the cockpit-mounted control unit. And even the older SPX course computer talks the current NMEA2000 based SeaTalkng language.

Not an improvement, in my opinion. I imagine they would be in the way, as well as exposed to weather. I also wonder how easy they would be to steal.

The ST2000 does 10,000 lbs. The Evolution units (as per the older Smart Pilot X series) are permanently mounted units (with a removable tiller drive unit) and go up to 13,200 lbs). I think beyond that Burt would be into a below-deck solution for the drive unit and possibly an upgraded control unit as well (i.e. step up to EV200). There was an older SPX5 unit with a ‘Grand Prix’ tiller drive that could do 16,500 lbs.

It was easy to install, easy to use and in fact worked better than the 4000+ on my current boat. The EV1000 might be a little small for your 33. With crew, gear, fuel, water, etc., you’re probably up to the top end of that 13,000. Better to have the extra power for windy days. The unit can be disconnected quickly, but don’t drop it; They are a bit fragile inside. Also, buy a water-resistant Sunbrella cover for it for when it rains. The seals on my tillerpilot were less than perfect, and it died in a Keys rainstorm when water dripped onto the computer board inside.

From: Burt Stratton via CnC-List Sent: Tuesday, March 03, 2015 9:58 AM To: cnc-list@cnc-list.com Subject: Stus-List Autohelm I am also planning on installing an autohelm before the next launch. My boat (1974 C&C 33 ¾ tonner) has a tiller. I have found what I believe is an appropriate tiller pilot from Raymarine. (EV-100). It is rated for vessels up to just over 13,000 lbs displacement. My boat is listed at just under 10,000 lbs dry so I should be OK with this unit. It looks reasonably simple to install. I don’t have a GPS or radar (yet) so no need to interface with anything else. Does anyone have experience with a tiller drive system who might be willing to share it? I am wondering how difficult (or easy) it is to disconnect and stow the drive unit when I feel like using my hiking stick. There isn’t much room in my cockpit (it is configured differently than the MK I) and I don’t want to install something that will be constantly in the way.
