    Spark plug confusion and block drain plugs

    My 5.0 OSi-E came with Autolite APP605 spark plugs. Based on the poor job done on the rest of the motor, I decided to see if those were the right plugs. I could not find any reference to those plugs. As far as I can tell, the volvopentastore site calls for Volvo spark plug # 21467472 which...

    MIssing riser gasket

    Bought a 5.0OSi-E (model 3869270, serial 4012110198) to re-power my boat. While looking it over, it looked like there were no riser gaskets so I took the riser off, and sure enough, no gasket was there. Everything I have read and seen calls for a gasket between the exhaust manifold and riser. Is...

    Another whiner...fuel pump that is.

    Bought a 5.0OSi-E (model 3869270, serial 4012110198) to re-power my boat. Wanted to start it up before installing to make sure it runs OK, etc. It would barely start and then die. Began to hear a whining from the fuel pump. Went out a hour later to try again with pressure tester connected to...

    Shimming the shift shoe stop bolt

    In replacing the shift shaft/piston seal on my SX-M1, I found out that the eccentric piston was badly pitted right at the seal and I am having to replace it. I had to remove the stop bolt from the old piston to put in my new piston. There is a procedure for shimming the stop bolt using special...

    How to flush/wash SX-M1?

    I have a SX-M1 drive that looks like it might have a little rust residue inside. There was a brown streak that came out with the drive oil (which looked new BTW). I took the shifter plate/panel off to replace the seal around the shifter piston as it was leaking during the vacuum test. The...

    Repairing 4.3 GXi with SX-M

    I bought a 2006 Regal with a 4.3GXi-F and an SX-M. I knew when I bought it the engine needed work...possibly replacement. I got it home and began looking at it and it needs replacement. It was used in salt water and has been sitting in salt air (Florida) for quite a while it looks like. At...

    4.3 normal temp at idle, cold at high speed.

    Just upgraded my 1998 4.3GL (4.3GLPBYC) to a GS. While I had the top end apart, I thought it would be a good idea to replace the thermostat since I had it off anyway and it was probably the original. The boat ran fine last year, BTW, but i figured an easy maintenance item to do now to help...

    4.3GL impeller change questions

    I'm replacing the impeller on my 1998 4.3L GL motor. The kit has two black rubber "plugs" in it (shown in the middle of the gaskets). Where do they go? Secondly, 2 of the gaskets are very similar. The existing one on mine looks like the one on the left, but I don't know why the one on the right...

    Any good place for used parts?

    Looking for a 4-barrel carb for my 4.3L engine (4.3GSPBY). Are there any good sources for used parts? Any good/large salvage yards maybe? I have tried the usual suspects (ebay/craigslist) with no luck. TIA, -Keith

    How to remove the manifold from a Penta 3.0 Liter

    I have it loose, but it hits the exhaust pipe when trying to remove it. Is there a way to remove it with the motor still in the boat? The picture shows the area I am talking about. If I can remove the stud, it would come off. Is that the correct method? TIA, -Keith

    Starting to get water in oil.

    My "new" boat had been sitting for the last 6 years. It has the 1998 4-cylinder 30GSMBY Volvo in it (picture of tag attached). I've got it running now but am still leery of it until I get a few trips under my belt. Took it out for a couple of hours last weekend and it ran good. Checked the...

    I need help finding the part number for my SX trim sending unit.

    Before I dump a bunch of money into the wrong sending unit, I hope someone can make sure I order the correct one. I have an SX-CT2 outdrive and TSK-SX-C1 Transom (pictures of serial/model #'s attached). The unit on there now has 3 wires going to it. I gather there are at least two...

    I have an SX-CT2 drive???

    Hello, New to the forums. I just bought a boat with a Volvo Penta SX-CT2 drive that has been sitting for 6 years. I am in the process of going through the major items to check for functionality, but I don't find any reference to my particular drive on the volvo penta parts (or any other) site...
