Thread: stabilizers

    Re: stabilizers

    Sky, I use an Oberdorfer pump that pulls water from the old air con pump thru hull. So far no loss of prime underway. The fact that we are in So Cal we took out all of our AC units and gained a ton of storage space.

    I used to have water maker priming issues after a run. I replaced the slotted camshell with a South Bay strainer and the problem is gone.

    Currently I'm using the thru-hull that was the pick up for the old Galleymaid head. Its behind the stabilizer fin so I think I'm getting air pulled under there as the fin moves. I'm thinking I'll have to add a new thru-hull deeper down and away from that agitation.

    Wouldnít be easier to just use raw water from one of the engines? Thatís how it is usually set up. The only reason to use an electric pump is when the stabs have zero speed capability and run at anchor with the engine off.

    That's how my system was initially set up. Did not get sufficient flow to the oil cooler. I'm on my second raw water cooling pump and still fighting oil overheat issues.

    Couple of months ago I replaced the oberdorfer cooling pump on the 116 with a march and cleaned up the hose run. Donít know who and installed the pump but they had done a lousy job installing it right under the chillers. I used a March TE 5.5C-MD. Itís only used with the zero speed.

    Last year I added flow indicators and I realized that at idle speed the engine provide almost no flow to the hydraulic cooler. I only picks up over 850/900 RPM

    Re: stabilizers

    I had flow issues with my original setup off of my 6v92 cooling system. I ended up moving the water pickup closer to the raw water pump and that helped. When we got these new Cats, I didn't see any good place to pick up water and Cat would not recommend a location to do so either. That left me with adding a pump which I did but I just took water off of an existing thru hull. So my new plan is to just add another thru-hull in a better location.
