    2000 - 200HP OX66 - Fresh Water Flushing Issue

    ? Is anyone familiar with what route the freshwater goes directly after the freshwater flush elbow ? What is a next step to unclog ? Can a poppet valve have this effect ?

    2000 - 200HP OX66 - Fresh Water Flushing Issue

    I don’t think the scaler is able to penetrate when connected to the freshwater flush…. I had used a similar product connected to a hose and let it sit under pressure for 4 hours with no effect. This seems like it needs to be mechanically cleaned I just don’t know where the blockage is. And, I...

    2000 - 200HP OX66 - Fresh Water Flushing Issue

    Here's something I am trying to get my head wrapped around. I have twin 200's. One has a newer powerhead - both are running well 'at the moment'. Both are running water through their systems when on and keeping things nice and cool. Both pee holes flowing nicely. The older of the two will...

    9.9 2 stroke ‘91 cooling issue

    Barrel was plenty deep, about 3’ deep x 2.5’ wide, but not when prop moving… the flushing port would have been forced water and I wanted to see how water pump was working. You’d need a real test tank - oval shaped, or a test prop, two things I don’t have…

    9.9 2 stroke ‘91 cooling issue

    Update: All is working. Took her for a Bay test - water flowing perfectly. Due to the fact that ‘Mickey Mouse ears’ can’t be used to flush this engine, I used a large garbage pail filled with water. THIS WAS THE PROBLEM; At neutral/ idle, the water flowed from telltale perfectly. When put...

    9.9 2 stroke ‘91 cooling issue

    Did the air. If the vinegar and then acid didn’t do it, the engine would need to come off and would need to be disassembled to be cleaned. (1) bolt on exhaust and (2) bolts lower on the cylinder heads feel like they’ll be b*tchy to remove, with a high snap! probability.

    9.9 2 stroke ‘91 cooling issue

    )&£¥>^* !!! Feel better already. Engine starts and runs perfect. Water flows out of telltale at idle, while in a large barrel. When put into gear, and brought to a higher RPM, the telltale stops flowing. When put back into neutral and idle, the tell tale will not return to function. Replaced...

    Cool Fuel Pressure Regulator - Testing

    I reinstalled the FPR and boat started right up after winterization. I'll check pressure again. The pump sounds louder than I remember, but it could just be that I'm focused on it.. If the pump/ cool fuel apparatus was in an easier location to get to, I'd of pulled it already. Hard to see...

    Cool Fuel Pressure Regulator - Testing

    If the fuel pressure tested 35 PSI with vacuum attached, does that sound within an acceptable range ? I just tested the FPR and it checks OK. Is it safe to say that once I reinstall the FPR, and disconnect the FPR vacuum, that it would bring me to 43 PSI ?

    Cool Fuel Pressure Regulator - Testing

    Engine is a 2003 5.7L 350/300HP. Narrowing down a low fuel pressure issue. Removed the cool fuel fuel pressure regulator ( a real bear to get to and remove ) A few questions: I'd like to test the fuel pressure regulator's function while out of the boat - is this possible ? If so, how do you...

    Bravo 3 overheating - oil expansion

    I'm back. I have been to Offshore Only - minimal recommendations - one good lead - the guy retired. Anyone have personal experience with East Shore Marine - Lindenhurst, or Pearl Grey in Amityville ? Thx
