Hi Guys
I have just bought an AQD40A/280SP in a 25' Ali fishing boat. I have upgraded the RW intake to a short run thru hull pickup and changed to 2 x 70'C thermostats. This has greatly improved it's cooling efficiency (82'C average at 2800rpm, extended run on a 40'C day) but as I am in the NW of Australia the RW comes in at 31'C at this time of the year so it will still get into alarm (90'C+) if I run at high throttle (3200rpm)
My question for you is - Can I upgrade my RW pump to the much larger diameter unit that is on later models? Such as on the AQAD40A? Is there any other way to upgrade the RW inlet system for greater cooling efficiency?
TIA
