Note,  the bleed plug installed on the top of the thermostat.  There is also a bleed plug at the TEE going to the left (return) water heater hose.

Many users say they installed a bleed point right at the water heater as that is the highest point in the coolant system.  Westerbeke sells an auxillary expansion tank for use when the water heater is above the engines expansion tank.

PS  He reported that he is still using the Oberdorfer 3 GPM pump and his max temperature is 165 at prolonged full 2800 RPM, but he does now have a 16 x 12 three blade prop and was not happy with the original australian two blade 16-1/4"x14 narrow prop as it would not make the boat go well in 30 knot head winds.   He did experience and overheating problem that was caused by a clogged exhaust elbow that restricted water flow and created excess back pressure.  The new red exhaust elbow shown here solved the overheating problem.
