No offence intended whatsoever, m'duck, but the problem with suggesting a "£1 Buehler" motor is repeatability. It probably wasn't new for that price - unless it had fallen off a lorry at some time - but what was it exactly? Knowing you it was likely a perfect match for that very big hull but what does poor old Steamshed look for and where does he go to look? Very few Buehlers managed to trickle onto the model market now that our old friend Alastair G has disappeared, and trying to buy a single example from either Buehler or their agents would seem to be a waste of time. The only "model" retailer of big DC brushed motors appears to be Mobile Marine Models, but his website is so lacking in spec for the 'T' motors he sells that I wouldn't use one unless I was duplicating a known installation of one in a known model. At least with the MFA belt-drive lumps you know what you're getting - their website gives full details of size and performance. The 900 Johnsons from Steve Tranter also look pretty useful as they don't rev too highly on 12v.

How do the 850's rate at 2:1 reduction?
I was under the impression they are a bit power
hungry and will eat you out of amp and ohm ;D

Stavros:
Even with a reduction gearbox they still are power hungry......TBH The 900's that Steve sells will swing a 6ins prop at 6v all day and give you loads of power so why would you use a gbox...wich is noisy....thats my thought on the matter
