    Volvo Penta Trim Gauge

    First I would check the connections between the sender and the gauge to make sure they are clean and solid. Typically there is a connection at the back of the engine where the sender wires connect to the boat wiring, and the connection at the back of the gauge. If those are good I would...

    Volvo Penta md5a fuel not reaching engine after filter change

    I think the key concern is pre-filling a secondary filter on a diesel. Particles you can't see can clog the injectors. If there is only one filter in the system, I would fill it via the lift pump lever and not pre-fill. An alternative is to fill the secondary filter through the inlet ports...

    Impeller

    Looks fine, though I would clean up the surfaces that the seal contacts on both the housing and the cover. May want to pull the impeller to clean the housing. Compressing the impeller with a zip tie is an easy way to install it.

    Volvo Penta md5a 1982 diesel Delphi 296 replacement

    To properly bleed a diesel fuel system you need to completely fill the filter bowl. Then find the downstream lift pump and there should be a small lever on it. There should also be a bleed valve on top of the lift pump. Crack the bleed valve and pump the lever many times until you get a...

    290 DP Prop Cone/Nut Torque

    I've been noddling how I'm going to drill out the center of this broken center bolt with a left hand drill bit and I discovered a cool tool to keep the drill centered, a hinged sighting drill. The end of the prop shaft has an internal taper, so this should work pretty well. Thought I'd share...

    Maybe my turn for new boat time

    Plenty of cup holders though. I wish I had one!

    Overheating at 30mph

    Have you checked the water inlet on the drive, item #9 in post #7? If that's cracked that can lead to your symptoms.

    290 DP Prop Cone/Nut Torque

    Yeah, I think I didn't have the shaft cleaned enough when I lost the prop and thus tightened against some crud. Thanks for the insight and detailed procedure. I'll find a longer large rod or screw driver so I can attain a higher torque on the cone.

    290 DP Prop Cone/Nut Torque

    Good idea. I was thinking a thread lock, but not sure about underwater use.

    290 DP Prop Cone/Nut Torque

    Thanks. Good idea on the socket. I intend to use a left hand drill. I'm hoping it comes out easily when I haul the boat out this spring...

    290 DP Prop Cone/Nut Torque

    I had an issue earlier this year where I lost a rear prop on one of my 290 DP drives due to apparent insufficient torque on the prop cone and center bolt. I had used a Volvo prop removal/install tool and thought I had pretty good torque on the cone and center bolt. I acquired another rear prop...

    Jack up the bow while boat is on the trailer ...

    Just jacking it up should be fine. If you're concerned about overloading the rear axle, just put a piece of 3/4" plywood under the front wheels. If you know trigonometry, you can calculate the exact thickness you need.

    Draining the engine

    Not necessarily. The water jacket in a block typically just surrounds the cylinders and doesn't need to go below them. My drain is well above the oil pan. I recently had to search hard for the drains on my Volvo diesel engines and was surprised how high they were.

    Glastron SX 175 Gas Smell

    I would not put a sealant on the gasket. The gasket should be made of rubber and should seal well if the surfaces are clean and smooth. You don't know how the sealant will react with gasoline.

    Glastron SX 175 Gas Smell

    Yep. I greatly reduced my mild gas smell by replacing the hoses. I wish my sender gasket was as accessible as on this boat.

    Oil Change and Gear Oil Change issue . Can you help ?

    Just to keep things confusing, realize that the Cobra SX drive (Volvo joint venture) gets filled from the bottom.

    Slightly warm trailer hub

    One thing these instructions don't tell you is which direction to turn the nut to align with the cotter pin hole. I've seen posts where people say to tighten to the next hole from finger tight, but the proper way is to loosen from finger tight to get to the closed cotter pin hole, according to...

    Volvo Equivalent to '95 OMC Ford 5.0 EFI Multi-port Engine?

    Thanks! I know parts are NLA. I have been finding them so far, either used or old stock, which is how I've been limping along so far. I know I'll eventually need to go to carb, especially once the ECM goes. I just wanted to know the Volvo number more out of curiosity, and possibly as an...

    Volvo Equivalent to '95 OMC Ford 5.0 EFI Multi-port Engine?

    I'm curious what the Volvo equivalent designation is for my joint venture '95 OMC Ford 5.0 EFI multiport engine is (50FAPHUE). I assume it will be something like Volvo 5.0 GXi, or something like that. Does anybody know?
