Hi,
I have a 73 IO-520 powered 185 and have an issue with the cabin heat.
The airtex pastic outlets on the side near the front edge of the door are discolored due to heat and were before I bought it 4 years ago.
I had noticed that during climb on colder day 20F ish it doesn't warm up much till I level off. It then heats up fine requiring the heater knob to be 2/3 the way in to be comfy.
Today I reached down and felt the airflow and was surprised at how low the volume was, with the heat wide open, but it was very hot, too hot to keep my hand close to them.
It had just come out of annual so I had the mechanic look at it and he said it was all hooked up properly. He then mad mention of the inlet which is just below the oil cooler and commented on how it didn't have much room to get a good blast of air. It was not obstructed just not much room, 3/4" maybe from the bottom of the cooler to the round inlet opening.
This obviously had been that way for some time per the Airtex plastic discoloring mentioned earlier.
Just wondering if anyone else has this issue and is there a fix/mod for it?
