    Thank you all, I appreciate this forum. This hobby helps keep me sane, but also sometimes causes me to overthink things.

    DIY trim sender repair using a 500 ohm potentiometer

    If anyone needs to replace a dead or janky trim position sensor, I did the following. For reference, Unit removed from engine was 3855074 which google says 1999 trim sender 3 wire model # 3855074 replaced by #3849411. The replacement sensor was pretty pricey for OEM and the aftermarket units had...

    Right Hand Prop versus Left Hand Prop - OEM versus installed

    replying to myself, found another forum entry that suggests all is not equal in LH versus RH prop setup. There is a brass keeper ring (aka wear washer) that gets stressed in LH mode, and not stressed in RH mode...

    Right Hand Prop versus Left Hand Prop - OEM versus installed

    Seems like it would be a no-brainer for one to switch the linkage and change prop direction in the 2nd half of a boat's life - to radically increase the life span of the cone clutch? Assuming everything else is more or less within operating parameters. I appreciate the replies, I am quite...

    Right Hand Prop versus Left Hand Prop - OEM versus installed

    I am confused, can anyone help me stop overanalyzing? 1998 Four Winns Horizon QX with 3.0 and Cobra SX drive. I believe the drive unit is a 1996, because the label on the drive unit says 1.97:1 gear ratio, and the OMC cobra PDF says that If 1996, 3868391 decodes to 1.97:1 gear ratio [if 1997...

    Volvo Penta exhaust riser

    And then a version plumbed to the steering cooler (mechanical or power). Good luck, interested as to which is most correct for your application/swap.

    Volvo Penta exhaust riser

    To add to the puzzle, it appears Volvo was making some various configurations for the 3.0 during the 90s. Here is the color cooling diagram, shows a version of the hose from the riser but this time to the exhaust itself.

    Volvo Penta exhaust riser

    Page 463 of the Volvo Penta service manual shows the 98 model of the 3.0 has a hose to the riser from the thermostat block.

    3 trips out 2 ignition modules went bad

    Amazon specials, or ACDelco? I don't think the aftermarket units are sufficiently hardened for marine environments, nor do they necessarily have the correct timing curves. my 2 cents.

    I am inquiring out of ignorance, is that a marine carburetor, it may be the direction of the pic, but I don't see the bowl vent?

    Trailering boat with outdrive struck down?

    I thought there is a manual release screw in the pump housing - for just such a scenario. Granted you have to manually lift the sterndrive and support it with rope, but the hydraulics have a bypass. at 10:53.

    Volvo Penta 3.0GS Restrictor Plate position on Riser

    I am pasting the color cooling system diagram, which in my humble opinion confirms the direction of the slot. Because I was also really confused and just trying to put the darn manifold back together.

    Volvo Penta 3.0GS Restrictor Plate position on Riser

    I also struggled with this issue. The OMC manual, who makes the engine had diagrams suggesting the slot went port side. However, the Volvo manual stated clearly to install the slot toward the engine and also specifically said in bold to disregard any markings on the restrictor plate. I went with...

    Video: What The Heck is This?? - 1999 VOLVO 4.3 GL - 2 bbl Holley Carbureted, ETS ignition

    Update: The “HYSTER IGNITION IGNITER MODULE 1460387” which has “GM 399 4L01” seems to work perfectly, it has base mode, and the curve is correct. It appears to me to be legit GM OEM part in case anyone is searching. Front side: GM 399 4L01 466 Backside: 399 6D50-02 SINGAPORE Reference...
