    2007 3.0 Not Getting Fuel

    I have spark. The idle is rough and bogs out when accelerating then cuts out like it is not getting fuel

    2007 3.0 Not Getting Fuel

    I have a fairly steep driveway and the engine acts like it's not getting fuel. I have drained the tank, refilled with non-ethanol 87 octane, changed the oil, filter, fuel filters, plugs, wires, rotor, distributor cap, set the timing and set the carb to spec. The only thing I can think of is the...

    2007 3.0 Carb Settings

    What is the factory spec for the air/fuel mix screw?. I've seen posts that say 1.5 turns out, 2 turns out, 4 turns out

    2007 3.0 TKS Fuel Filter

    I replaced the fuel filters today and noticed the carb filter has a small gasket that goes between the filter element and the cap. The dealership said it's only available as part of a entire gasket kit. Does it have to be replaced?

    2007 3.0 Rattling/Timing

    I decided to get another gas can and siphon the rest of the tank out. As far as the filters go, I have one on the fuel pump and one on the carburetor. With as difficult as the one on the pump is to get to does that have a longer service interval?

    2007 3.0 Rattling/Timing

    I was able to get it down to 1/4 tank of gas and the old stuff didn't smell bad but was darker in color

    2007 3.0 Rattling/Timing

    Right now the boat has 3/4 of a tank of fuel. I'm going to try and transfer the tank and get it down to around 1/2 and top off with fresh non-ethanol 91 octane to be on the safe side. I figured blended would be better than running what's in there straight

    2007 3.0 Rattling/Timing

    When following the procedure for putting it in base timing mode I noticed it idled a lot rougher so I would assume it was in base timing mode. On that year the manual calls for 2 ATDC.

    2007 3.0 Rattling/Timing

    Well after setting the timing to 2 degrees ATDC and replacing the plugs and gapping them to the recommended .045 gap she runs perfect at all speeds now. Had to fine tune the idle air mix in between lean and rich stumble

    2007 3.0 Rattling/Timing

    I already put a bottle of octane booster in it before I even fired it up for the season

    2007 3.0 Rattling/Timing

    I have not checked the fuel filters. It has almost a full tank of fuel that is at least a year old. I was waiting until I use that up then refill with high octane non ethanol gas and replace the filters at that time

    2007 3.0 Rattling/Timing

    I have not had a chance to take it out on the water yet after adjusting the timing and replacing the plugs

    2007 3.0 Rattling/Timing

    The timing was so far off I didn't see the mark on the pulley until I started rotating the distributor. Could the distributor be off a tooth?. The only thing I hadn't done yet was new spark plugs. The factory manual calls for .045 gap and the old ones were .032

    2007 3.0 Rattling/Timing

    That is with the engine idling and on the number #1 cylinder. I checked the firing order and the wires are 1-3-4-2. I thought maybe the firing order was off by one at first but the engine wouldn't start and backfired thru the carb

    2007 3.0 Rattling/Timing

    I have a 2007 MerCruiser 3.0 with very low hours. I had the boat out for the first time and noticed under hard acceleration a top-end knocking sound. I immediately backed off the throttle and at cruising speed it is not noticeable. Running on muffs it's not noticeable either-only when under a...

    Towing Boat In Cold Temperature

    I'm buying a boat and it's about a 500 mile trip. The problem is the temperatures are supposed to be well below freezing. The engine is already winterized but I'm concerned with any structural issues and fiberglass/cold temps

    Volvo AQ125 Sat For 20+ Years

    A good family friend passed away recently and his family is selling his boat. It's a 1983 Trophy with a AQ125 engine and 270 drive. I know the history of it since it was bought new. The boat has been in the water maybe 10 times it's entire life and always freshwater lakes. It has been kept in a...

    2006 Yamaha F115 Engine Misfire?

    I've always had OMC or Mercruiser 3.0 I/O's but my new boat has a 2006 Yamaha F115 four stroke on it. The engine has 108 hours and always starts right up and runs well but I have noticed when idling it has a intermittent slight miss to it. I also noticed it when holding 1800-2000rpm. No other...
