So added the oil temp gauge & sender (spare port just in front of adapter on the block) & oil looks in line @ 160~180 degrees 40~45 psi. It takes some time warm up but stays consistent once there. My water temp is 100~110 & 20~ish psi. I'm running no thermostat (per Whipple direction). My thought is the water too cold causing condensation in the valve covers. Should I add some more breather or put a thermostat back in the water? breather on stb side now, pcv on port. I'm scared to add thermostat against Whipple direction, they say steam pockets form & poof goes the head gasket.

I called Merc, they do not have another stat for the stock, so guess I'll be looking into aftermarket, I'd like to just find a pad adapter with one built in like the stock so I don't have to re-pipe everything.

Somone was looking for this so might as well bring it ttt

After reading thru this thread, it has me wondering if I need to upgrade my current Mercruiser oil system...
http://www.mercruiserparts.com/Show_...And+Oil+Filter I'm getting close to reassembling my motor & with upgrades, I should be in the 600HP range. I will be running the 10778c pump. Will the existing cooler set-up work with this, or should I look to go aftermarket? The oil lines are 1/2", & I don't have any restricted fittings. Everything worked fine at the original HP...The temp seemed to be a bit high (240 during a long run), but I figured it was where I'm reading from (in the block). I had planned on welding a bung in the pan & reading from there... Very good information here...It definitely has me thinking... |
I'm right in the middle of setting my 253 up and going to redo the factory merc stuff..already have a eddie marine block adapter(canton they told me) so need cooler, filter, oil temp, and lines...damn had all this right on my 251 !!! + going to make sure the 30psi valve is in there...great info here !!!

I believe the stock pad has a 165*. Is there a direct replacement for that?
