    how does one flush out rust from block?

    This! Anytime I use an acid product, I buy a bunch of baking soda, neutralize it, and pour it down the drain.

    Volvo Outdrive I.D.

    Here's a tip I learned. The bolts that hold the shift linkage cover on are the right size to pull the retainer.

    Volvo Outdrive I.D.

    Thanks guys. I didn't realize this was possible. I'm more accustomed to my SX-M drive, but I'm getting good at pulling my 290 DP drive these days, sadly more for warranty work than yearly maintenance. I'll have to checkout how to pull just the upper gear box, just to understand it.

    Outdrive Oil Leak

    I would also check the gear oil to determine there is water in the drive. (milky oil). Need to pull the lower drain pull and let a little dribble out to this.

    Volvo Outdrive I.D.

    You need to pull the whole drive (less the transom mount) to replace the bellows. Not sure if that's what you mean by upper gear box. Pulling the "whole drive" removes the upper and lower as a single unit.

    Gear Oil Pump Storage

    Me too. I zip tie the outlet to the top of the pump so it doesn't dribble out.

    Volvo Penta DP-SM Steering actuator leak. 21910902

    I would go with Five Star.

    First start after lower unit rebuild - new boat owner

    If you're referring to the smoke/steam, that is independent of the lower unit service. It's associated with the engine and it may clear up when the engine warms up. The reason you shouldn't run the engine with the drive up is because it is very hard on the U-joints at the top of the drive...

    How to bleed trailer brakes

    Check the manual for your surge brake actuator. There may be a way to bleed it with a flat head screwdriver from below, like on my UFP/Dexter actuator.

    Should I be worried

    It looks like you may be able to swap the winch post and the jack so the post can move forward, assuming here's enough clearance to operate the jack behind the winch...

    Storage on land

    Just use a trickle charger.

    Coupler

    Brake cleaner would work well, as well toothbrush on a stick. Have you checked for proper alignment with an alignment tool? If it’s out of alignment, it would have similar symptoms…

    steering actuator

    Is it a Seastar actuator? Their website has manuals on seal replacement. A different manufacturer may have similar manuals.

    Transom removal on SX

    I find the bigger risk of corrosion are the screws that hold on the trim sender on the starboard side that covers the said pivot housing bolt. Do the same thread treatment described above on the threads if you get them out without breaking them...

    Transom removal on SX

    You don't need a 12 point. Just use a regular hex six point. I forget the size.

    Volvo Penta raw water nipple removal question.

    I just used a hammer with the pivot housing on the boat. Clean the square recessed area on the housing and grease with triple guard grease, or equivalent, so it comes out more easily next time.

    Overheating under load

    If you saw the temp climb on muffs, with no real load, then I suspect you still have an issue. I believe 140F thermostats are more for raw water cooled systems, whereas 160F is used for closed systems with a heat exchanger.

    Dometic RV fridge RH460LD any good?

    One big benefit of compressor refrigerators is that they are way more efficient (lower amps) in DC mode than absorption. If you're running off a battery/solar, you want a compressor refrigerator. I don't hear the compressor frig on our 30' boat.

    Head holding tank pump out

    I went through this on my 21' cuddy and just replaced the john with a porta potty. Super easy to remove and pour down a toilet. How much capacity do you really need for a day trip or three?

    Trailer surge brakes

    That's a good question. I suspect the "self-energization" has a relatively small effect on overall performance given all the things at play in these surge systems. For instance: - Larger surge actuator piston diameter would create lower brake pressure (bad), but less actuator stroke or...
