Hi Again, both the 100e Albatross boats in the family are sealed systems, raw water simply cools the oil in the sump. Both these sealed systems have thermostats, and do get quite hot on occasions. I had a V6 Delta with full raw water cooling and a thermostat and that never got really hot however hard you ran her. Hope that helps Cheers Kgarla

On raw water systems like you have, there is normally a steel disc with a hole in it fitted where the thermostat was to raise the temperature a bit. As for size of the hole in the disc you will have to get a few made with different sized holes in them & it will be a matter of trying them to see which gives the best results. I don't know what sizes to suggest however as I have never had to do this myself.
Mercs are like women, no 2 are exactly alike. That's what testing is about. In general it is safer to test motors and props than women!

Thats a great idea..and one that has been tested ??? or not? i do not have a thermostat fitted so i guess a slight restriction would work...
