New jet pump housing

My new jetski pump just arrived. The old housing was really corroded and out of round, this new one is muuch better nick, as you can see if you look at them side by side:

Hmm, the budget really is getting eaten into though:
Cost: $120
Total so far: $320
Hopeful end budget: $1000
Money remaining: $680

Investigating this, investigating that. General investigation.

After several discussions via email and on forums, i'm second-guessing my decision to use a jetski pump and motorbike engine. A few options now present themselves:
* Use a smaller bike engine (eg a 110cc engine) for less weight and better physical fit
* Build a bigger boat (a glen-l squirt seems to be a common option)
* Just put a 10hp outboard on the back
and, of course my favourite option:
* Continue on my current mad path

I've researched to find that 2-stroke short shaft 10hp motors all seem to weigh around 36kg. Now when the hull was designed decades ago, i'm sure that those motors used to weigh more, lets say 45kg.
I just weighed my jet pump on the bathroom scales and found it to weigh 20kg. Now i believe i can shave 5kg at least off that when chopping it down to fit better. So, that leaves 45-15=30kg for my bike engine. I haven't weighed it yet, but if it's around 30kg, i can put it in the boat knowing that all up, i'm weighing the same as an outboard. So i just need to weigh the bike engine now. Its tricky hanging on to these heavy things while balancing on the bathroom scales!

Also have found a nearby (ish) timber store that knows about boatbuilding timbers.

Plans arrived!!!

So excited to see a nice fat envelope when i got home from work today:

The plans arrived!!!

Its alive!

Finally got the bike / boat engine to start! Awesome!
There's nothing that start-ya-bstard stuff won't get going :)

Plus a bit of angle grinding to get the airbox and the carby out of the way. I'm sure there's a way to get them out without chopping the frame in half but this was easier and more fun :)
