    Sx gear oil change shouldn’t be this hard

    One wonders why it's not Torx or Allen head. But it could be harder. A VP duo prop requires you to remove both props (using the tool) and the drain plug is behind the back prop.

    SX-A tilt / trim pump replacement tips?

    I brought a Mercruiser trim pump to a place that rebuilds starters and alternators. They rebuilt the electric motor part of the trim pump for a lot less than a new trim pump. Had them do the electric motor part of an winch that mounts on a trunk bumper.

    Volvo B20 AQ130 Water in Oil

    Most (pleasure) marine engines die of water ingestion rather than wear out. That's why it's important to pull the exhaust manifolds and risers every so many years. Less often fresh water, more often salt water. And in FWC then only the riser needs to be pulled. So the simplest thing to do is...

    Another winterization question

    You have not said RWC or FWC. Assume a V8 so a drain plug on both sides of the block. There is the possibility of pockets of water in the block even after draining. Many pour some pink RV antifreeze into the block. It will mix with any water in the block. Couple of gallons. You need to...

    Dpsm 1.95:1 outdrive toast

    If the gears are fine then the drive is rebuild able. But shavings have circulated throughout the outdrive and all bearings need to be inspected. Rebuilding is not an easy task. Special tools and following the Volvo Penta manual are required.

    FUEL PUMP

    I believe the hose from the carb to the fuel pump is in case the needle valve on the carb gets stuck and fuel continues to flow into the carb bowl. It drains into the fuel pump. I do agree with a marine fuel pump. There are no paths to outside of the engine or bilge in a mechanical fuel pump...

    How to winterize aq151a - changed oil recently.

    If heat exchanger then it's FWC. Drop the hoses from raw water pump into bilge or something to catch a pint or two of water. If they are not different size hoses remember (or mark) where they go. Don't want to flip them. Look for a blue plastic wing-nut type of drain plug on each exhaust...

    FUEL PUMP

    You may need a control with a timed relay, maybe a diode to prevent voltage going from the + lead on the pump to the starter solenoid (assuming you are pulling power from the starter solenoid to run the pump doing cranking) when power is coming from the oil pressure switch to the + lead on the...

    FUEL PUMP

    I think if the diaphragm breaks the gas goes into the oil pan and with no gas pressure the engine stops once the carb bown empties.

    8.1 GXI-J Cranks but No Start w/ Diacom Logs

    You could pull the plugs and turn the engine over and see if any water comes out of the cylinders. If it does then likely a manifold or riser problem. Seems to me you have two issues, loose head bolt and water in the oil. The only way they are connected is by what is now a head gasket issue.

    5.0GL fuel small leak near the water fuel separator and possible starter solenoid issue

    You will need to inspect the pump housing to see if the repair kit or full kit is needed.

    2004 Volvo Penta SX-M1 Outdrive Cracked Bellows.

    Pull the drive and get the bellows off. You can fix it in the spring. If anything is rusted and needs replacement you can order the parts. Some can take awhile. The Volvo Penta OXI and OceanX versions detect water in the bellows.

    How to winterize aq151a - changed oil recently.

    Is it a FWC or RWC? If you have less than 10 hours on the engine oil I would skip changing it. Drive gear oil gets changed. Change the raw water impeller. Other winterizing steps depend on whether it's a FWC or RWC engine. The Volvo Penta owners manual has the information for winterizing...

    multiple error codes

    I would start with a mechanical oil pressure gauge and a thorough cleaning of the connectors involving the ECM and sensors connected to it.

    Volvo AQ Trim Module

    How much is a new one? You not only need to design it, you need to build it for the marine environment. A couple of years ago I looked for a module to control an electric fuel pump when converting from a manual fuel pump. I could not find one for the marine environment and went back to...

    145 a volvo penta winterize procedure

    So winterizing in a FWC engine is different than a RWC. Since you mention antifreeze I assume it's a FWC engine. Test the antifreeze or extract a little and put in a Dixie cup in your freezer overnight. I would suggest you review the owners manual for winterizing instructions. Most are...

    Volvo Penta V8-430-CE-M Overheating

    Melting of the impeller is typically because the engine was started without water going to the pump.
