Default Advice on cross over BBC's
good day, I just installed b&m 250's on my 525sc engines. had to delete the circ pump and added the crossovers no bypass. no T stats boat seems to run fine (1 hour so far) but I am starting to wonder if the seawater pump might be overloading block with water pressure? let me know thanks in advance.

Do you have a water pressure gauge? Are you running T stats?

I have similar set ups and run no T stats. Ended up using restrictor washers to control water psi.

no water pressure gauge, no T stats where did you install the restrictors? how much water pressure are you running?

The restrictor washers install where the thermostat goes. I am pretty sure I am running a 5/8”...

5psi at idle, 15psi at cruise.
