    Mercruiser V8 6.2l MPI with Smartcraft SC1000 to Garmin GPSMap plotter connections.

    I could have worded that better. Yes I noted the NEMA flow sensor, without it (or a gateway) the OP won't be able to see GPH on their MFD (plotter). My answer was just directed to their questions about SmartCraft GPH reading they get on the Tach. To get SmartCraft data on their plotter will...

    Mercruiser V8 6.2l MPI with Smartcraft SC1000 to Garmin GPSMap plotter connections.

    Fuel GPH is a calculation based on injector on time done by the PCM on the engine (as mentioned above), but isn't 100% accurate due to the PCM doesn't know what the fuel pressure is. It assumes the PSI is within specs. Yes, it is delivered to the helm on Can Line P. You are correct that you...

    Need a new throttle

    The change from Gen1 to Gen2 Remote Control / Cables happened early 00s. So your 08 is probably compatible with new controls.

    2025 Mercury 115 powder coat issue on cav plate

    The ones I have seen are shiny but I wouldn't call them high gloss like you would see on a new cowl.

    2025 Mercury 115 powder coat issue on cav plate

    If these are the silver painted bottom half engines. STOP. Ask your dealer for a copy of service bulletin Outboard No. 2024-10R1 This is a special issue with the silver paint.

    Mercruiser 5.0 twin engine high water pressure

    Update to my advice: The T on your engine should NOT have an orifice in it. That was only used with Alpha packages. I would still check it and the distribution housing for any restrictions, the Bravo raw water pump can put out a lot of pressure. My guess is your problem is in housing, 3 Ts or...

    Mercruiser 5.0 twin engine high water pressure

    Check that the thermostat fully opens @160° ±5° When you have it apart ---- it might be a good idea to check the orifice in #20 T as @AllDodge and I have suggested. A blockage there will cause high water pressure. A Bravo sea water pump supplies way more water volume and pressure than the engine...

    Mercruiser 5.0 twin engine high water pressure

    This picture you posted shows a hose below the thermostat housing. There is a T in that hose. That T usually has a orifice in the bottom of it where the hose goes to the "easy" drain housing. The two hoses that come out of the T horizontally go to the exhaust elbows. But you say that you don't...

    2007 Volvo Penta V8 5.0OSi-F intermittent failing issue

    I'll add that using cam retard with a scanner is the most precise method to set the HVS. Because that is what the ECU uses. That said, Volvo didn't do a good job of getting the correct spec in all the manuals. It's there for some models and not for others. Also it can change from year to year...

    Mercruiser 5.7 Guardian Mode

    PITOT CKT LO, Fuel LVL CKT HI, FUEL LVL2 CKT H are faults you can ignore if your boat doesn't have those features. Most faults can be detected with the engine running, or with the key ON but the engine not running. However, some faults require the presence of engine RPM, and cannot be detected...
