![]() ![]() During the training exercise, all three occupants of a 19-foot patrol boat were ejected. ![]() On June 1, 2017, Anderson County Sheriff’s Deputy Devin Hodges was conducting on-water training exercises on Lake Hartwell in South Carolina. These devices are critical pieces of safety equipment if the operator is ejected from the boat.įailure to use an ECOS can have tragic consequences. Wireless ECOS are electronic fobs that automatically cut off the engine when they detect they are submerged in water. When the operator gets too far away from the helm, the lanyard disengages from the ECOS and the engine automatically shuts down. This term encompasses both physical lanyards and wireless options.Ī lanyard ECOS physically attaches the vessel operator to a switch that shuts off the engine if the operator is displaced from the helm. Commonly referred to by recreational boaters as “kill switches,” the proper term for these devices is engine cut-off switch (“ECOS”). Be careful that the cam does not get in contact with the carb roller!!! Keep throttle cable disconnected during this setting.Under a new federal law that went into effect April 1, 2021, the operator of any powerboat less than 26 feet in length overall (LOA) must wear an engine cutoff switch while operating a boat above no wake speed. (Do not have the book to verify the value).ģ: Adjust the max timing advance similar, but use the HIGH tab and be carful not to disturb the LOW tab.Ĥ: Launch the boat, start warm up the engine until quick start gets disabled.(Boat must be launched to get correct back pressure)ĥ: Adjust the throttle plate idle mix screws according to the book.Ħ: Adjust the LOW tab until desired idle rpm is obtained. The ignition triggers, when running in normal temp mode, when light beam is 'broken' and in cold start when light 'opens'.ġ: Verify the engine TDC corresponds with the pointer at TDC, and adjust if needed.Ģ: Set INITIAL idle timing (4 degr) by turning flywheel to pointer is at 4 ATDC (?) at the timing wheel.Īdjust with LOW tab until light goes out. Beam open -light ON, beam broken -light OFF. The 'system' is fairly simple when using the box.Īs we are dealing with a light beam as trigger and not a magnetic field, the advance setting might be done static, engine not running. We have tried about 5 times with the same results. According to the book, the sync light is surpose to go out completing the last step. If we move the optical sensor itself, the sync light goes out, but as we move the tab's the light stay on. My problem is, the sync light is not going out. The next step according to the book is to move the high and low speed tab's on the optical sensor until the sync light on at the top of the box goes out. My mechanic, placed the timing wheel right at 4 degreesTDC, the sync light came on, on the box. According to the book we can be up to + - 4 degress from TDC. On the optical sensor, there are 2 tab's high and low idle. (forgive me I don't know what it is called) its used to tell whether or not the optical sensor is bad or good and to time the optical sensor. My mechanic has this box, (an optical engine analyzer or something) anyway, it has 3 lights on it good, bad, and sync. Thats why i was asking about the kill switch, I thought the kill switch had to be in place inorder for the motor to run, What am I missing, I am so confused. I have checked everything I can think of, and exchange almost every moving part, except the key switch. We tested the power pack, it was good, we checked for spark, it was good, The carb's were just rebuilt, we checked everything on this motor according to the book and the spec's, everything was by the book and in range, compression was 125 on each cylinder. We replaceed the following parts Power Pack, Coils, Optical Senor, Timing Cap, Starter, Stator, Fuel Pump, Fuel Filter, Spark Plugs and wires fuel bulb and lines. It takes about 7 or 8 tries before I can get the motor to catch where I can get back to the dock. ![]() While i'm on the water, I have to quickly put the motor into gear for the motor to catch. First off the motor will start but it won't stay running. I have had the motor looked at and here is what we did. OK, now that I have that question answered, I have an issue. ![]()
