Hello,
I have had problems with my AQ170 not exhausting properly and I have traced back through the cooling system to find that the valve in the exhaust elbow has melted and broken into bits due to previous overheating issues (it is/was just a spring and a ball bearing in a plastic housing/cup) . However now it is removed, I do not know where to find a replacement or whether it is needed. Please if anyone has any information into what that valve is for ( i believe it to be a relief valve?) it would be very much appreciated but also, can i leave it without one as it is just coolant water exiting through the shield rather than the exhaust riser to the bellow, joining to the sterndrive. I do also have sufficient amounts of water exiting the sterndrive flapper housing with the exhaust fumes, therefore does it need a replacement? can i just leave this exit uncapped to exit through the transom shield, rather than only the bottom of the leg?
any info would be appreciated,
my apologies if this comes across vague or stupid.
