Hello. Working w. a 1993 Bravo 7.4 engine (SN: 0F009622). From what I understand this engine originally came with a two piece seawater pump. But mine seems to be a one piece pump...so I guess this one isn't the original one.
Anyway, I've been trying to get this boat started after 6 months of not starting. Finally getting it to start reliably, but it keeps overheating. No water coming into the T stat housing, nor any coming into the oil/power steering cooler. So I checked the impeller. It's toast. All the pieces seem to be stuck in the sea water pump housing. So I remove all of the old impeller and buy a new one. With the housing facing me, I twist it in clockwise, same direction as the engine when you're facing the pulleys (so pulleys moving clockwise). I start her up again. No water at the Tstat again. Shut her down. Button her up as I've run out of time. Then back home I check the pictures I took and realize that the INTAKE hose had a T connection for another hose.
My questions are:

My questions are:
- If this other hose is not capped or put in water, then the sea water pump is going to be sucking in air and can't suck in water, right? (picture shows intake hose w. the T connection
- Did I put the impeller in the right direction? Clockwise?
