I have just finished getting a Glastron V142 with at 68 Evinrude 40HP Lark going. It is a 40873D with a Generator. With the engine off and running lights turn on with no issue. Running the boat in the water if the lights are turned on the motor drops rpm and cuts out. Turn them off she runs...
I recently acquired a 40873D outboard. On the exhaust cover what am i missing on this open threaded fitting? I cant seem to find it listed on Marine Engine dot com. Thanks
