Running my motor on dry land

check SKIDIM, Overton's, Barts, or any other large distributors of Boating supplies. Fake a Lake are kinda sorta a modified sink plunger that connects to a garden hose and fits over the water intake under the hull. Other devices are afixed in line inside the motor box that you can attach a waterhose too. You can just disconnect the line and insert the garden hose directly and tighten the clamps. Keep the transmission in neutral and keep the RPM down low. Some say below 1500.

stick the waterhose in your water intake hose that way you can run it on land

I made a fake a lake from stuff at Lowes. 1 plunger, 2 female hose ends, 2 hose clamps, and a 10' length of clear 3/4" or 5/8" hose. Just cut a small hole in the plunger, push the hose fitting through, attach the hose and clamp and another hose fitting and clamp at the other end. All told it was about $10 and 10 minutes to put it together. What I really like about it is that with the extra lenth of hose, I put a small on-off valve on the end of the garden hose and can control it from inside the boat, no hopping in and out to turn it on.

Yeah, I should point out that the standard plunger handle worked out to be the right height for the boat, otherwise I would have put a block under it or cut the handle shorter. Kind of lucked out though...
