Because I had my prop smashed last year on the Monmouth canal. I am having to buy a new one. My engine is a 25 HP Kubota and a Enfield leg. Can any one tell me what is the best size to buy for canal/river use. I was using a 13x9 but I could not tell if it was working OK because of lack of water under the boat.
You have my sympathy.Had the same thing happen on my local ditch.[The Huddersfield Narrow] [Shallow] Rather than buying a new prop,I had mine overhauled by Streamlined Propellers,for about half the price of new.It came back like new. What are we paying our licence fee for if the CRT can't even ensure sufficient water in our canals?
What a cracking idea. Then I wouldn't be dragging the bottom of a shallow canal. Maybe thats the way for us all so the CRT wouldn't have to dredge the canals.I could say a lot about the money they waste which should be spent on maintenance, But I don't want spanking for telling the truth.
Both my recent boats had a heavy weight "skeg" (I think its called) that is a continuation of the keel below the prop and rudder similar to Ian's photo. No such arrangement on Normans as far as I know.
Because of my problem with the Brecon canal not being deep enough. My investigation has revealed that even narrow boats on the canal have also had there propellers broken. The canal was originally dug 4ft deep to allow horse drawn boats fully loaded with a draught of 3ft to travel. The canal is less than 2ft deep in places. If there is very little water under the boat the propeller will suck the water from under the boat and drop it closer to the bottom. Hense any rocks etc will damage the propeller. Back to my original question can any one advise me as to the size of prop I need
