    Riva Open Loop Difference.

    Wow, Very nice difference. I love how the hull is cleared up and the engine compartment stays much cooler.

    Me Likey!

    Hey Ocman, Do away with that Oketer clamp on the Riva stat. and get a T-bolt clamp. When the thermostat closes is has a great amount of pressure behind it and has poped off on me once until I went T-bolt clamp.
    Doent hurt your motor, but makes your bilge work like hell when it comes off.

    It was 97 here today and my engine compartment stayed very cool. Ran wide open lots I could put my hand on the valve cover and not get burned.

    Love the system.
