hey guys,
i recall seeing a thread a while back regarding the ideal way to plumb your water lines. because i had a completely different set up prior to my rebuilds and upgrades i wanted to be sure and plumb correctly.

is it OK to run all oil coolers after the sea pump or should they be before? my only thought was if i ran the oil coolers before the sea pump that i would have to use the rigid cored (non collapsable) hose. this is much more inconvenient and difficult to work with as you know.

i am not sure what way i would choose to do this at this point however if it is critical to go one way or the other i would just a soon start heading in the right direction.

thanks,
john

PS if rinning the water hose to the coolers is a must could you let me know as to why. i just want to know for my own knowledge i could see where the water temp would be a little cooler before the sea pump. but.....

I would run them after the sea pump. Thats how merc engines are set up. Never really thought about doing it any other way.
