2006 Four Winns Funship 224 Volvo Penta 5.0 GXI Takes Long to Get Full Power & RPM
Hi All - first post here. Have had this boat about 4 years now. It had about 60 hours when we got it. It's now at about 140 hours. I have annual maintenance (oil changes/drive inspection/winterization) done by the same place I bought it from. It's been trouble free until a couple weeks ago when I noticed it did not want to go past around 2200 rpm when I first took it out. It felt weak on power naturally.
I always warm up the engine for several minutes before going out and I always ease into the throttle, but this time as I was easing into it, I could push it further and further and it would just stay at the same ~2200 rpm and not pick up speed. Over the next few minutes, it would slowly increase engine speed and water speed until it suddenly felt like it regained all the power it should have and would build rpms again as expected.
It's repeatedly done this every time I've taken the boat out since (maybe 5 or 6 times now).
I know car engines very well (have built them from the ground up), but I'm not well versed on boats outside of the engine itself - as it's just a car engine with some small differences.
So, I started with the basic fuel filter change first. I've taken the boat out once since and didn't really notice any difference. I poured the fuel out of the old filter and didn't notice any obvious debris or water. I nearly always fill up on the water with premium (non-ethanol) gas, but I have put a few gallons of auto pump gas (with ethanol) into it a few times in the past when I didn't have enough to make it to the pump on the water.
I'd love to hook-up a scan tool and see if the ECU is storing any codes, but have no idea what tools are out there for this engine. There's no OBD-II port of course and not sure if there's a diagnostic connector at all on this engine. A few connectors look like possible candidates. I've found some scan tools, but they are specific to different vintages of MEFI and I don't even know what version this engine is... Volvo Penta couldn't even tell me after a phone call.
Bottom line, I'm looking for some feedback before I start throwing parts at it. Plugs, cap/rotor, wires would be my next steps without knowing any better. Appreciate some insight. Thanks.
