I am also checking into venting the raw water at the strainer to get the air out.

oil temp
i have been told that if the oil temp never gets above 212,then the water /moisture never boils off.the guy at merc said between 200-250 is ok.just my 2cents.my fountain runs around 230-240.

Mine will get up to 250-260* after a long WOT pass.

I agree with that statement, but have to ask why the manufacturers make oil thermostats designed to keep the oil above 212* then?
Water will evaporate much faster when it is boiling than when it is just hot.

I agree with you that water will boil much faster at a higher temp. I have no idea why the oil thermostats are designed to keep the oil thermostats above 212*. It would be interesting to see if you can monitor that with the merc computer while a engine is running.

I have heard statements regarding this multiple times, and here is what I think regarding that. Water boils at 212*F water does not need it to be 212* to evaporate. At 180*, the water will evaporate in no time. A pool evaporates water at 80*. Now what happens when a drop of water hits the connecting rods which are going to be hotter then hell. Goodbye water drop.

If this isnt necessary, I can sure save a lot of gas by not running 5000rpm all the time and cruise all day at 4200rpm with 180* oil temps.
