    Volvo Penta 5.0FIPNCSCE SLOW mode

    Try grounding the oil pressure switch (breaker) connector to ground and see if you can get above 2500 rpm smoothly. It sounds like it's something else. Can you use a portable fuel tank of fresh fuel?

    Volvo Penta 5.0FIPNCSCE SLOW mode

    The SLOW system uses separate temperature and pressure SWITCHES that are independent from the sensors (senders) that go to the gauges. I suspect the breaker is the switch. I believe the switches are normally closed (ECM sees ground) during normal operating conditions, but I'm not sure. If you...

    Steering Actuator P/N

    21910902 is apparently the replacement part number for 3858128, so order the newer part.

    Steering Actuator P/N

    The actuator is the 385 number. The other is likely a subcomponent housing part.

    SX-C1: gaskets when doing bellows/gimbal?

    The only seals that need replacing when pulling the drive and replacing those parts mentioned is number 88 and the O-rings for the drain plug, overflow port, and dipstick. As preventative maintenance, you may want to replace 13, 14, & 15 as these can crack and create air leaks into the raw...

    Exhaust Manifold and Riser - HOT

    I would get a $25 IR temp gun and measure it. Mine never get much above 120F. If either of yours are much more than that, I would pull the riser and see how much corrosion exists. Last year mine went quickly from mildly warmer to so hot I could smell the large rubber hose smoking on a WOT...

    When does anode require replacement?

    Make sure the anodes are well bonded, electrically, to the drive. Them not getting smaller is a potential sign they aren't bonded well to the drive.

    Hooked up my battery with the wrong polarity

    Why not? Other than not running high rpms on muffs due to limited water flow, are there other concerns with running up a motor in neutral?

    Limp mode

    Note that the ECM receives inputs for limp mode from both temperature and oil SWITCHES, not sensors. The switches open at high coolant temp or low oil pressure. Find the switches and ground each connector to the block to determine which is one not closing at normal temps/pressures.

    Weight distribution hitch didn't fit trailer rails

    My thought is that your questions are moot since you're severely overloading your tow vehicle and shouldn't be towing your boat with it.

    Use Volvo oil for best results.

    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.
