Some of you will be aware of my recent adventures: Land Rover Madness - One Step Beyond!
All good fun and games but I have a serious question for the Prop Polishers - can RIBnet come up with a better prop for this puppy? (see photos below)
The "vessicle" is powered by a very standard engine - I think it's a 300tdi so maybe making 100-125hp? I'm not sure if it's still turbo charged. Actually, I need to get more info about the current set up - prop size, shaft fitting, HP etc, but we can think about it anyway. The current setup makes a top speed of 3.5kts. We'd like to increase that by a knot - it would help immensely!
Some facts: The vessicle sits partly in the water and steers with it's front wheels and/or a tiller. The prop is JUST below the water and there is a crude anti ventilation plate fitted to the bodywork. The drivers tend to run it in fourth gear
at 1500rpm. At those revs it makes 3.5kts and if pushed harder will begin to overheat with no noticeable increase in speed. I understand that she is aircooled as per a standard landy - not seawater cooled. I'd say we could look at a radiator spray fitting to resolve that!
The current prop is from some sort or canal barge or cruiser - or so they think.
The total rig must weight 2.5 tonnes loaded. It is a heavy displacement load. One catch is just that - the prop can't be deep enough to catch when driving on land. Anyway - your thoughts please?
