"Hi,
My MD21B has trouble with cooling at above 3800RPMs. I started some research on it, and found out that my first suspect would be the filter on the sea water going to the heat exchanger.. The problem is, I cant find it.
Heres how it works: Sea water goes through the valve in the bottom of the boat and in on the port side of the transmission. Then on the other side of the transmission it comes back out and goes directly into the oil cooler, and from that to the pump and heat exchanger.
Now, correct me if Im wrong, but somewhere along this route there MUST be a filter? The MD21A has them just before the oil cooler, but on MD21B theres just a pipe to the transmission..
Any ideas?"
