    Sparkplug - carbon buildup - causes?

    Hmm that sensor is right beside the thermostat housing isn't it? Fuel pressure has not been recently checked. I will though. I've been tossing a Rinda. Cant decide between the techmate or diacom though... If I could run the diacom on an iPad, that would be ideal. Cant though.

    Sparkplug - carbon buildup - causes?

    Hi all, Changed out plugs on both motors (2008 VP 5.7 gi-j). Port appears to have a lot of carbon build up, starboard appears to be okay (picture also attached for reference). Probably about 100 hours on the plugs if I were to take a guess. All appear to have about the same amount of build...

    Injectors

    Hi all, I'm looking for suitable injector replacements for 2x 5.7L GI-300-J. Volvo Penta part 21141691. Anyone know of a reputable place that sells refurbished that have been tested and cleaned? I want to stay away from ebay. Any suitable non OEM replacements?

    2008 Chaparral 275 SSI 8.1 Volvo Penta GXI-J Soft Alarm Issues

    I've been emailing them and they replied that the J series (even though mine were made in 2007) takes the CAN style as you just found out. In my opinion, we are lucky as that is the upgraded one is my understanding. I think it fits more applications too?

    Tach issues

    Sorry if this is in the wrong section, but figured this issue will primarily be electrical. All, I'm having some tach issues. Port goes between 700-2000. Starboard stays at 200ish. Both are recording hours. Motors: Volvo Penta 5.7L GI-300-J. I believe the tach gets signal from the...

    All, I'm having some tach issues. Port goes between 700-2000. Starboard stays at 200ish. Both are recording hours. Motors: Volvo Penta 5.7L GI-300-J. I believe the tach gets signal from the ignition coil via the gray wire. My plan was to check the wiring connector at the ignition coil...

    2008 Chaparral 275 SSI 8.1 Volvo Penta GXI-J Soft Alarm Issues

    2008 Chaparral 275 SSI 8.1 Volvo Penta GXI-J Soft Alarm Issues

    I was actually just checking these out. There is a different adapter for years 2007 and then 2008 onward. My boat is a 2008, the engines are 5.7L GI-300-J. I'm probably thinking manufactured in 2007. Any way to check this? It isn't on the serial number tag.

    Delrin valves

    Hi all, I have a new to me Westmarine RU260 (circa 2015 I think) which was made by Zodiac. Anyway, it has Delrin valves as you can see in the picture. The problem is that you can't get accurate pressure readings because of the rubber flap valve and I can't find a pump that is suited for this...

    Volvo Penta 5.7 no spark

    What is meant by found and restored small resistances? So they ohm measured at the plug and sensors, then cleaned the terminals?

    Low and high pressure on AC unit

    Hi all, I have pulled the manual ans done some pretty extensive Google searches to find what the low and high pressure readings should be on my Dometic Marine Air Systems VCD12K, 205 31157 circa 2007. From my searches, it appears there is information that low should be 70psi and some other...
