    I have not checked that cause we tried 3 different carbs with the same problem, but its worth a look. Thanks

    Engine stalling when you give it too much throttle on take off

    Carbureted engine, PCM 351 BOSS. So far tried rebuilding original carb, then purchased another factory style carb, then replaced fuel pump and then replaced the factory ignition and finally, got a completely different brand new holley carb. Nothing every changed, Stalls when you give it too much...

    Ended up being a restriction at the cool fuel fitting, tiny piece of impeller wedged into the opening cause its only the size of your finger

    Bravo 1 water pressure issues

    It was a restriction that allowed just enough water through to function but made it hard to build pressure at start up.

    Bravo 1 low water pressure

    Finally found the problem, piece of impeller stuck in the cool fuel fitting. The hole in the fitting is only the size of your finger, even though the hose is 1.5 inch. So the v shaped piece of impeller perfectly wedged into the hole but allowed enough water through to function. When the...

    Well i stuck a camera on the transom to check out the thru-hull fitting and doesnt seem like a problem but its hard to get a good angle on it. Can see a little grease dripping off the steering arm from above, at first i thought it was rust but when i zoomed in its just grease. im gonna focus on...

    5.0 MPI Misfire Under Load

    hope you got the merc OEM part and not the cheap china copys, the price is tempting and they look identical but the materials are super cheap and dont last./

    Bravo 1 low water pressure

    yeah i posted a video of the water flow through the transom. I hooked up a garden hose inside the boat and back flushed it. Seems like enough flow but if i had an air leak it would not show up in this kind of test. Maybe i should look on the inside of the transom to see if the fitting is leaking...

    5.0 MPI Misfire Under Load

    Seems #2 is not firing so its either an injector needs cleaning or its not getting spark, maybe a plug wire got pinched or pulled out? Put it on the hose in the driveway, pull the #2 spark plug wire and listen for any change. If the RPM does not drop then your not getting spark. Even if the...

    Bravo 1 low water pressure

    i had a sudden drop in pressure readings this year, as if a blade had broken off. When i found it the impeller was fine i started reposting to this thread. Since changing the sensor didnt do anything i assumed my problem is getting worse after years of staying the same. If im using the...

    Bravo 1 low water pressure

    oh i didnt have to turn the hose on very much to get enough water, tape stayed on no problem. I posted a video of how much the hose was running

    Bravo 1 low water pressure

    this is my 4th sensor. Clearly theres enough water coming through the hose as seen in the videos. Not sure why its so hard to build pressure on startup. Gonna pull the drive and check the thru hull fitting, after that ill add another external thru hull pickup this problem is 5 years old

    Bravo 1 low water pressure

    Using the Rinda scan tool for readings. Does it look like enough water coming out of the Lower unit?

    didnt you see my duct tape LOL. I only removed the tape when i was back flushing the hose

    Bravo 1 low water pressure

    My condition is worse, low PSI even when starting it cold, only 5-10psi at cruise. Thinking it may be a problem on the intake side of the pump. Hose looks perfect going from L/U to Transom. Could be the transom fitting i may pull the drive and look inside with a scope. Checked the new pump and...

    Bravo 1 low water pressure

    Those are great numbers. Mine takes about 5 seconds to get 2.5 psi cold at idle, and 25 seconds to get 2 psi warmed up at idle. Crazy

    Im gonna look at those thanks so much!!!

    Bravo 1 low water pressure

    only does it when warmed up, builds pressure right away when its cold and thermostat is closed. Maybe it needs more flow and cant get it when the thermostat is open. But it never runs hot. i did run a cam up through the transom just saw some surface corrosion nothing major

    Bravo 1 low water pressure

    I agree, theres less backpressure when the thermostat opens, so less pressure at startup when its warm. Always runs fine, just trips the alarm when starting it after warmed up. Just an annoyance!!
