    Engine Bogging Down When Cold

    Replaced the sensor and also replaced the thermostat while I was at it. It has not been able to get up to operating temp all summer and now I know why - that thermostat was stuck open despot it being my 2nd time replacing it. Got it up to temp in the driveway and plan to do a water test asap...

    Engine Bogging Down When Cold

    The past two times I’ve been on the water, my 5.0 MPI won’t get full power until it has been run for a while. Once it gets warm it will run perfectly all day, but that initial few minutes that it doesn’t get full power is nerve racking. Any ideas what I should look at first to try and fix this...

    SC1000 Working Sporadically

    Got it. That seems pretty doable and is better than $400. Ordering a DIY kit from GaugeSaver as we speak. I’ll update as I go along and thank you!

    SC1000 Working Sporadically

    I have a 2007 Sea Ray and my SC1000 Tach worked well for a while. It then became a bit spotty and would only work occasionally but now I can’t get it on at all. The tach works but the smart readings won’t come on at all. The light appears to work, but the LCD screen isn’t showing anything at...

    Mercruiser 5.0 Won’t Reach Operating Temp

    Update Update: solved it! My pump had deterioration on the other side, as well. I had the right part for a good pump, but once they get beat up a little bit you need a separate impeller kit. The part number is 47-8M0137219 and it comes with a wear plate for the inside of the pump, as well...

    Mercruiser 5.0 Won’t Reach Operating Temp

    Well it wasn’t the impeller (pictured). I know the plate was worn down so I replaced it with the plastic Mercruiser housing, wear plate, and put in a new impeller anyway. I fired it up no problem after the install (had the belt on wrong initially like an idiot but fixed it quickly) and now it...

    Mercruiser 5.0 Won’t Reach Operating Temp

    Ok, weird weekend with temperatures - after replacing the thermostat correctly, it got up to temperature and maintained it on muffs and in the water. However, over the course of the day out yesterday, it started dropping in temp again. Got up to 160 at cruising speed and held, but was down in...

    Mercruiser 5.0 Won’t Reach Operating Temp

    Good to know. I bought it in November and have no idea when it was done last. I’m sure I didn’t help it along but it sounds like I was going to need to do it anyway at some point. Thank you very much for your help and I’ll post pictures of the impeller replacement as I go along. Dave

    Mercruiser 5.0 Won’t Reach Operating Temp

    Yeah, it’s a bravo 3 stern drive and the pump is indeed under the engine. Couldn’t be easy..

    Mercruiser 5.0 Won’t Reach Operating Temp

    Headed to West Marine to make another “donation” now. How long would you guess I have before I need to pull the trigger on the swap? Rough estimate is fine…

    Mercruiser 5.0 Won’t Reach Operating Temp

    Man, my face is a bit red on this one. I completely misunderstood the point of that circulation system, then. Thank you for the help!
