View Full Version : Raw Water Pump Hex Wrench Size

Can someone tell me what size allen wrench I need to remove the 3 hex head bolts for the raw water pump mounting? Boat is up at the cabin and I don't want to get up there and find I don't have the right one. Boat is an '88 Prostar 190 351. Thanks in advance.
