Coolant expansion reservoir on the starboard motor was empty a week ago. I refilled it and it went another week of steady 4-6 hr/day cruising before it went dry, but it does seem to be using coolant significantly more than before (we've been cruising at this pace since March).
I have white absorbent pads under the motors and don't see any signs of visible leakage
I've checked the transmission oil dipstick and the oil seems clean (I did an oil change 3 weeks ago). No obvious signs of "milkyness" or smell of coolant.
I have noticed the exhaust on that side has a faint white smoke look more than the port side
I'm thinking maybe the heat exchanger is leaking and the coolant is being blown out the exhaust risers?
Any support or other ideas?
Any idea how to diagnose this other than taking it off and pressure testing/fixing/replacing?
How hard are these to find?
Thanks
