An angle grinder gearbox can be used, the bigger the better. They are generally a 1:3 ratio, this combined with a bike chainring can give you up...
V15-I, modified from inline shaft to side shaft
Gib The Involute gearboxes as far as I know were made for a pedal boat which was manufactured commercially. It was basically a surfski hull...
Tom A 1:1 ratio going directly to the prop is going to be a big prop. I got my 1:2 gearbox from TEA transmissions and have found them...
Gib I use a TEA transmissions DZ22 1:2 gearbox, it is connected to a bike chain ring to give a 1:7.38 gearing at the prop. Setup works well...
Tom What exactly is a lobster boat? Number of people, load to carry, speed, open water or sheltered waters? Ian
Jeremy From an earlier post of yours:- "If a way could be found to transmit drive to a steerable leg and allow it to flip up if it hit...

h20 The sidewinder is a simple way of doing a pedal drive system on a boat, that is if you want to have a crick in your neck. I'm probaly...
Glen Putting in a system to change gears while pedalling isn't necassary as there aren't any hills on the water. It would be making your...
Scheny The wave interference hull is only 2.6m long, shouldn't be hard to build or take very long. Everyone will have their comments or...
Porta The carbon fibre prop is about 300mm in dia with the blades pivoting from a nylon hub. Two slots are cut in the hub with the blades...
V15-i Been busy upgrading my boat from an inline shaft to a side mounted shaft. Same sort of setup Rick uses, have put on one of his folding...
Tom I agree with your comment about cost of DIY. Also when estimating time to make it, take your worst estimate and multiply by 4....
