    FWD Drive (forward facing drive) Volvo Penta

    Being a surf boat, he can't go with an aft facing prop. OP, Once the issue is resolved (rebuilt, new), you need to use an aluminum anode given you're in both salt and fresh water. You also need to make sure you have a good electrical bond between the anode and the drive, and change them at...

    Volvo penta outdrive

    Drive ratios are tailored to the engine peak torque and horsepower. The 1.97 is likely aligned with a 4.3L motor. If you change ratios, you need to change prop pitch so don't over or under rev the engine at WOT.

    1/4" crown staples for bunk carpeting?

    I would be concerned about being able to pull them out when you replace the bunk carpet again. If they are relatively easy to remove, I would go for it.

    Spindle

    The surface you need to be concerned about is where the grease seal rides. If that's smooth, and the bearings not rattle around per above, you're good to go.

    Help Identifying Cooling Hose Part Number

    Found it after scanning multiple Volvo diagrams. One thing I've learned is that carbureted engines have the power steering cooler upstream of the raw water pump, whereas EFI engines have the power steering cooler, and fuel reservoir (cooler), downstream of the raw water pump. The initial part...

    OMC Cobra 5.0 302 1995

    Your intake manifold cover should say multi-port EFI, if it’s like mine.

    Help Identifying Cooling Hose Part Number

    I want to replace the U-shaped cooling hose in the image below (#17) that's between the fuel reservoir and the power steering cooler on my OMC 5.0 EFI motor (see signature for part number). Unfortunately, the parts number given for #17 is for a different hose (oil cooler to gimbal). The ID of...

    What was Causing this Clunking Sound? Binding Brakes?

    You shouldn't have trapped pressure in the system like that. There is something wrong with your actuator, or coupler; either it's not fully extending or there is a blockage internally. I would lubricate all the moving parts in your coupler and see if it moves freely, then also bleed the brakes...

    Starter extension/stand-off nut and bolt

    If the threads stop before a nut can bottom out, as illustrated in the picture, you'll need a metal spacer of some sort to ensure good clamping loads on the ring connectors. I think any spacer or washer will do. I would spray the terminal after tightening everything with CorrosionX, Boeshield...

    Volvo Penta SX-M ?- no water to raw water pump

    He has an OMC Cobra SX drive, which is the joint venture with Volvo and the same as the Volvo SX-M drive. There is no pump in the drive, like older OMC drives. @Tahoe Mike, First, I would backflush the entire system to clean out the impeller debris. Disconnect both hoses from the pump, and...

    Rapid Outdrive Anode Loss

    Thanks guys. I'm slipped in a marina with shore power with other boats using Volvo zincs. Thank goodness I can remove the props and access the zincs from the swim step.

    Rapid Outdrive Anode Loss

    I'm finding that the anodes on our Volvo 290DP drives are being consumed in about four months, while slipped in saltwater. Is typical for these drives? The previous owner of the boat had painted hull anti-fouling paint right up to the drive transom mounts, which we stopped adding to for the...

    Oil level too high?

    I have the same situation on my boat. It doesn't take the listed amount of oil to get to the full mark. Four quarts is slightly over full, whereas the manual says five quarts. When you check the oil, look at both sides of the dip stick. Mine will also show way over full on one side, but I...
