Anti-Freeze Drain Plug???

[Merrill Mant]

Our 1992 33.5 has a Yanmaar 3GM30F engine. I have searched the user manual as well as the engine itself trying to locate the drainplug for the engine coolant. Any tips in locating this plug would be appreciated.AmbitionMerrill Mant

There should be a small clear hose coming off a valve on the left hand side (if your on the side w/belts, looking aft) under your heat exchanger on the side of the block. It will be a grey, round knob about 1/2 in diam. Put the hose in a bucket and turn knob C.C.Hope this helps.Doug
