My buddy wants me to help him install a water heater... I need to know where to connect the water lines to the engine... its a 1999 mercruiser 5.7 alpha
Above is spot on. I just winterised a friends same set up. Need to remember and blow water out the coil when winterising. Many forget !
thanks! no winterising here in So Cal... it only gets down to a bone chilling (for us) 45 degrees :joyous:
can't see the relevant bit but that don't matter
do l still need to install the flash thingee for other relevant links there?

Think they should be 3/8 NPT. I would suggest going to the local hardware and take them with. The ones in the link show a gasket so they can get closer.
On my Formula the factory used the port side block drain plug to connect the hose going to the WH.
