New! from Enforcer Mfg Co.
Easy to install device attaches to your Zenoah water jacket as shown. Connect the black coil tap wire to one terminal and the second terminal to the engine block. Designed to stall the engine if water jacket temperature exceeds 180 degrees F.

No more worries of clogged waterpumps, or pick-ups resulting in serious engine damage when running your boat, or having to sprint to the other side of the lake if beached. If for any reason you loose water cooling the OKG is designed to activate and closed the coil circuit and shut the engine down long before serious over-heating can occur.

We have had this special heat activated switch designed and calibrated for optimum sport / performance gas model boating use. Switch recycles for restarts in 15 to 20 minutes time after cool-down.

To install:
Simply drill and tap a single 10-32 hole in the water jacket of your Zenoah engine. We include a paper template that shows the exact location for the drilled and tapped hole, and provides written details for installation. Installation can be done in as little as 10 minutes.

We will install the OKG for $5 if you send us your water jacket, or if you purchase a new engine from us.
