no water suction from out drive
 

:(...can anyone help me with this problem, i have no water flow through the system. i have the 1995Davanti 23.5 with a ford 5.8 fl volvo outdrive DP. i have changed the circulation pump, thermostat,
and have check the raw water pump which seems to work attaching a water hose by disconneting the outdrive feed. it was mentioned to me that there might be a pump in the outdrive to assist the raw water pump suction. If somebody could help me it would be great.
thanks to all, Lee
