    Losing Power - After two hours

    So it's been a while since I updated and still stuck, so figured I'd update. For anyone who doesn't want to back read. Boat fires perfectly, idles great and has good compression. Originally after a few hours of running the boat would lose power under load, would never cut out but lose power...

    Mercury Mercruiser 4.3 Low Pressure Fuel Pump

    Is there a big disadvantage to buying an aftermarket electric fuel pump vs the OEM or Mercury brand? The mercury brand is $300+ and the Peach Tree after market brand of the same model number is $90, just wondering, if anyone has had experience with them...

    Losing Power - After two hours

    Another update. Happy Father's Day to everyone. A little frustrated but new issues or reoccurring issues below. I know I bought a used boat but it ran perfect at the test drive and was hoping for something safe to take my daughter on, but at the end of the day it is what it is. Taking...

    Losing Power - After two hours

    Update: After changing Anti Siphon Valve and Fuel Water Seperator Took the boat out last night after work, hoping to be out for two hours and run it wide open as long as possible to get the engine as hot as possible. I dropped it in the water and the tide was low already and going out, so I...

    Losing Power - After two hours

    So I have half a tank of gas left, should I pump it out (i just added stablizer to it) and just start fresh? I don't have anything big enough to old all that gas that is in there, because I believe it would be about 35 gallons.

    Losing Power - After two hours

    It say for about two hours while we ran out and grabbed some dinner with friends, came back and it looks very much the same, the filled cup looked dark Yellow and the half filled cup very clear with a lot of black sediment in it, that didn't look like metal but more dirt.

    Losing Power - After two hours

    Tonight I changed the fuel water separator and the anti siphon valve. A few notes below 1). Picture attached of the gas that came out, first pic is the first full cup which has a tiny bit of sediment in it but mostly just gas, the second pic is the bottom of filter very light colored and a lot...

    Losing Power - After two hours

    Read a few articles and one thing about couples I've read everywhere seems to be a burning rubber smell and an awful noise, and I haven't experienced any of that. I have smelt gas as it was happening but defintely not rubber

    Losing Power - After two hours

    I am just a life time IT guy, who now managers construction works, unless I can type it with my hands, I ain't fixing **** or understanding anything with engines haha. So I can only describe what is happening, and for all I know the tach could be reading wrong and just over reacting. Cruising...

    Losing Power - After two hours

    That makes sense, there is no easy way to examine the coupler correct? Involves taking the outdrive off?

    Losing Power - After two hours

    It is so hard to explain, I will try and get out this weekend and take a video. My daughter has a soccer tournament, so I hope to squeeze in some time. Would a coupler work perfectly for two hours, not missing a beat then all of the sudden stop working, then magically work again the next...

    Losing Power - After two hours

    This happened on one trip and I instantly installed a new prop and hub, and it happened again on the next trip with the new prop and hub. The boat in that first two hours, ran perfectly, and better than ever, gaining cruising speed that I didn't have before. So I am positive it is not the...

    Losing Power - After two hours

    When I lose power and come to almost a stop (still not touching throttle) it revs back up to 5,000ish rpms, then settles back at where it was at 4,200. Once it settles back the boat starts going forward again, sometimes 5 mph, sometimes 8 sometimes 11, but never back to the speed I was going...
