    Volvo Steering Actuator unscrewed itself

    That was my thought as well. I see not point for this threaded point to rotate so I'm leaning towards some locktite

    Volvo Steering Actuator unscrewed itself

    So, I had the crimp / ferral right behind the power steering pump crack on the high pressure hose while I was out (where the hard line goes to the rubber part of the hose). Put a hose clamp on it to get by and refilled the reservoir. Hard to steer one way and the rubber PS lines were jumping...

    Volvo penta dp-sm splitting outdrive questions

    Must be. No good place to pry or tap either. I got a small screw driver in the most aft area and I can get it spread to see daylight and worked forward towards the bow, but near those studs it will not budge. It seems to me the nuts on those 4 studs were tightened and displaced aluminum to...

    Volvo penta dp-sm splitting outdrive questions

    Any tricks to pulling the Two halves apart? 4 nuts are loose, 2 large bolts in the back from the bottom, and one screw from the top are all out. Is it common for these two halves to corrode together? There is nothing in the prop area I need to do, right?

    Volvo penta dp-sm splitting outdrive questions

    There is a plate above the prop on my volvo dp sm drive that was cracked and missing a piece. It appears to be part of the Planing surface of the drive as well as part of the exhaust. Anyways, looks like I have to split the upper and lower sections to get one bolt out of that plate. Question...

    8.1 gi-b misfire / backfire

    Update and issue solved. Sent injectors out for cleaning since all diacom data seemed reasonable other than the iac was darn near wide open trying to keep it running and the timing light said it was sparking. Has to replace one injector, and don't try to cross reference to a gm part number...

    8.1 gi-b misfire / backfire

    I checking it under load when the issue was happening. Stayed at 40 psi. Granted, I cant run it up to high RPM with this issue so I can't check it there yet, but when thus backfire / miss happens fuel pressure is 40 psi. Trust me, I was hoping this was it.

    8.1 gi-b misfire / backfire

    I'm down to this. I bought a gm cross reference injector set and it ran worse with same symptoms. Turns put volvo put like 42lb/ht injectors on it and gm ran something like 26 or 36 lb/hrs. Injectorsnarenbeing sent out for cleaning and balance and flow test. I destroyed one getting it out.

    8.1 gi-b misfire / backfire

    Really, I thought 8psi on the low pressure pump and 40 on the high pressure pump, all plus or minus 4 psi was the spec. What do you think it should be? Totally agreed on flow testing injectors

    8.1 gi-b misfire / backfire

    Key on engine off I've the throttle through the range of motion and it went from 0 to 100 % pretty smooth. Not sure what happens when you unplug the map. I assumed the speed density map had to have that to run?

    8.1 gi-b misfire / backfire

    8.1l gi-b chapparal 26ssi 2002. I'm pulling my hair out here. Idle seems a bit rough, gets way worst with throttle advanced. Will pop / backfire. Compression all cylinders at or near 150psi. Replaced spark plugs. A few looked Carbon-ed up. Diacom power balance test shows 6 and 8 are not...

    Outdrive or gimble bearing noise and overfill

    This is an odd one. I was in some rough water and flooded the boat pretty bad trying to get to land. Water up to the distributor in the engine bay. Engine was still running and we got it pumped out. Obviously water got into the gimble and bellows as the drive shaft was under water. Got on...

    Mecruiser 5.0L MPI distibutor proper clocking?

    5.0L MPI Engine Serial OM618927. read a service bulletin on my issue of a miss fire at higher loads. It also stated to rotate the distibutor 1-2degrees if the issue persisted. I did this and the problem got so bad that at about 2500 RPM it misses so bad it sounds like the ECU is reducing...

    Mercruiser J1939 database

    Anyone know if the Mercruiser MPI motors use the standard J1939 database and diagnostic messages? If they don't and use all proprietry messages, anyone have a database or a list of the main messages? Anyone know the baud rate? I'd like to hook up my CAN buss development tool to the boat and...

    U-joint for a Alpha 1 Gen 2

    I'm trying to replace the U-joints on my Alpha 1 gen 2 drive. The serial number is OM464998. I believe I need part number 865496A02. These things are $130 a piece, for a non-zerk fitting simple U-joint for pete's sake. Can anyone confirm that this is the right part number? Does anyone have...

    Distributor question 5.0L MPI

    So, I've been trying to track down a miss / hesitation coming out of the hole and while at WOT. I took the distibutor cap off and there was water dropplets in there as well as a ton of white corrosion on the center post, the cylinder posts, and the button. Is this normal? Also, the base of...

    Can't identify motor year

    Hey all, I looked and searched for a site to decode the engine serial number to get the year, but all I get is the model number (4M4102LRS) The serial number is OM618927 on my mercruiser. It should be a 5.0L MPI 260 HP. I just can't figure out the year. (I'm having a miss fire at all RPMs...
