160 Degree Thermostat?
I was planning on running 160 degree thermostats in my engines. Engine builder would like to see 180 degree. He is not a boat guy so I thought I would ask here. If you've seen any of my other posts I have 500hp engines with aluminum heads. I boat in Lake Michigan. Thanks for your comments.

140 degree. shhhh….
Mercruiser OEM 140f seem to be more reliable than the aftmkts.
Some use 120f but those are hard to find now.
We actually care about oil temps more.

F2 Speedy, Honestly, at this point I'd rather not say. I have a entire $hit$how going on another post about my valve guide clearance. Maybe you could tell me safe range and I'll check my paperwork.

So.....I'm asking for a friend....what would worry you more about the clearances on the mains and rods? Too loose or too tight? Mine are really close

to tight in a marine application with constant load on the engine they may gauld and spin a bearing, same as a tight valve guide heat expands and sticks the stem as JD showed in his post
