Trial #1

 

I did not build this boat but I did make a few modifications before even putting it in the water.  I changed the stock flex cable a bit so that it used a brass sleeve over a smaller then original telfon tube.  I felt this would provide more support for the flex cable to prevent cable whip.  The boat did not come with a propeller.  I wanted to use an Octura X442 but it did not fit the drive dog adapter so I ended up using a Prather 220.  Other then the prop, the boat is stock using the 700 motor that comes with the flex drive setup.  I ran the boat off of 12 cell 3000mah or better batteries.

The boat moved out and got on plane quickly.  The water cooling setup worked well and there was plenty of water coming from the cooling exit.

After I got comfortable with the boat, I tried turning tightly.  I was never able to spin it out or get it to hook.  The boat handles very well.
The boat was a little slower then I expected.  The motor did not sound like it was reaching a decent RPM.  The motor was also getting a bit warm.  It looks like the 220 prop is too large.

Since I did not have another prop for the boat I tried raising the strut and moved the batteries forward.  This helped and the boat was faster but still could use a smaller prop.

Trial #1 Conclusion

The boat was slower then I thought it would be.  A smaller prop would probably help.  If a new prop does not do the trick, more batteries and/or a stronger motor should.  The boat did pick up some water.  I noticed that the part of the plastic rear bulkhead had been cut away to the wood bulkhead stiffener and sealed with some silicon.  I don't know if this is where the water is coming in but I think I will redo it just the same.  I also noticed that the decorative exhaust stacks are not sealed.  A little bit of silicon will solve that.  Looks like I have a little bit of work to do before the next trial.
