Hi all,
I'm new here, can't even spell my name right lol. I have a 1994 Cobalt 222 with a Mercruiser 5.7 carbed motor. I bought this boat 3 years ago, its my third boat, should be the nicest one I've owned, but has overall been a headache. It always tended to start a little hard, and it seems the more money I throw at it, the bigger the problem gets. At this point, I have had the carb rebuilt twice, new plugs, wires, cap, rotor, fuel pump was replaced right before I bought it, and I have a receipt for that. All work was done by a professional boat shop with a good rep. Also, had the impeller changed, the manifolds, risers, and gaskets. It will be going back into the shop in a couple weeks, as the last time I had it out, it would move fine at lower RPM's, then it would start slipping/over rev when I tried to increase throttle. I'm HOPING the rubber busing I hear about near the propeller just rotted out or broke, as the prop did hit some sandy bottom right before this issue happened. However, my main question is, I can usually start it relatively easy in the driveway on earmuffs, but if I go to the gas station and then home, or towing it out to use it at the lake, it seems like it makes it REALLY hard start after moving around. I had the gas checked, no water in the fuel water separator, gas is fresh, just seems like if its been sitting it will start easy, but after moving/towing it around it wants to hard start like its out of gas. It cranks away, then crank,crank,crank like it almost catches and wants to start, then finally starts. Once its running it tends to run good other than the recent RPM/slip issue, but I have had all the parts I could think of replaced to help with this starting issue, as I hate sitting on the ramp for a couple minutes cranking trying to get the engine going. Two boat shops told me its just how the boat is, but my previous 1992 Bayliner with a 305 that was carbed started like a champ, no issues like this at all. I'm ready to sell this and get a fuel injected boat, but with kids and finances being what they are, I'd really just need to keep this one if I can get the problem figured out. Can you add an electric fuel pump to replace the mechanical one? Would that potentially help solve the hard start issue, as it seems like its acting like its out of gas before it starts? Even after its started and ran around, once I park it and go to start again a little later, it hard starts again....any ideas let me know, thanks in advance for any help or suggestions.
