[PSUBS-MAILIST] Personal_Submersibles Digest, Vol 16, Issue 36

I would recommend that you purchase the plans. Each K boat is going to be a little different and I think it would be extremely difficult to build one with just a parts list.

>> Graham,
>> A jet ski jet is gigantic for a psub.  Jet ski's have 50hp and more, the one I have is from a 750 cc two stroke engine.  Mine has a 3 inch nozzle at least maybe more.  Jets are very bad for maneuvering, they have no grip in the water like a prop.  Yes fast ferries use them but they are owned by governments, check the fuel tank size lol.  I would do some reading about jet viruses props.  Don't get me wrong, I love the idea, and it is a fun idea, I just don't think it will do what you imagine it will.  I hope I am wrong.
