Boat is S2-7.9 retrofitted with
Yanmar 1GM (not 1GM10).
Boat is on
trailer. Winterized with normal
coolant flow thru
exhaust system one year ago. Started
engine (08/09/15), ran well, BUT no
coolant out of
exhaust. Checked obvious, impeller,
pump shaft rotates at cranking, no
leaks found in system. Have two foot rubber hose in bucket connected to
pump. 1) Does the
muffler system have to be filled/primed after this long
storage? 2)Is hose length too long run into bucket? 3)Does the rubber hose need to be primed? 4)How long can
engine run without
water thru system?
