I am honestly flabbergasted at all the insightful and helpful info you have given me.many thanks to all,...its going to be a bit of a cruiser and not a racer I'm afraid!...so Yamaha 4stroke is looking favourite..xtra long shaft!..what do you all mean by Voom, is that another motor option?...Yet again thanks for your help and I'm sure i will be firing a few more questions as they come up...
