Thanks Roy and Chas for the further comments.
The motor is pretty sound. I have run it from a 12V stabilised mains supply with no load, and under load. Seems to run very sweet indeed! Have just ordered a 12V lead acid gel battery off eBay, so tests with that soon!
I asked about the reversing here, and I started another thread too, but quickly got shunted back to the website about tycol motors. Its a fascinating site, but I couldn't really get the answers I was looking for (probably down to my limited knowledge/understanding!). I was hoping someone could provide a 'do this, then do that' instruction on making this reversable! Normally I would just be happy with a forward running motor, but she is quite a sizable boat (I briefly considered bow thrusters until I saw ow much they were!).
Thanks again for any help heading this way
Bill
PS I have started 'structural renovation, and when I have made enough progress, with enough photos, will start a thread
