Christian is correct. I have a lot of fun with my E27 but I've spent way too much on for it not being my forever boat. I'll sail it for another couple of years and then move up in size.
I have a E27 that had the inboard removed years ago and I replaced it with a Nissan 9.8 extra long shaft w/four blade prop (with no transom cutout). I have had the boat up to 6-7 knots routinely.
If look closely I drilled a small hole through the transom so the remote control cables would work more freely without having to bend over the transom.
On my E27 (with Tiller) I have a extra long shaft 9.9 Nissan outboard with remote control (Throttle and F/R) mounted on a retractable bracket. The Nissan remote control console is mounted near my legs where the original inboard engine controls were. I leave the outboard in a fixed position...
You have to take the end cap off the boom and I believe the pin on the goose neck has to be drilled and a s/s cotter pin goes in. Pull the end cap off the boom and you should see how it works.
I use the main halyard and tie a bowline (do not use the shackle), then I use another halyard for a safety back up. You will have to have a able body seamen to help winch you up. Anytime you can relief you weight by placing your foot on the spreaders or holding to the standing rigging do so.
