    Trim/tilt issue 1996 Volvo Penta DP

    1. Volt/ohms test 2. Jump the control wires, green down, blue up. Reverse polarity to test up and down 3. Maybe, could also supercede to a different pump assy 4. Depends on the tilt/trim model. Some AQ style systems have a trailer switch, most just use a gauge with no limit. SX uses no limit...

    Changing upper oil seal in Mercruiser alpha one

    If you indeed have the older style bearIng/gear set WITH the spacer (as outlined in post #8 of this thread) there is no need to check the rolling torque unless you want to.

    trouble getting reverse.

    Based on the photo in the post quoted here it would seem the sea water pump in the drive isn't supplying cooling water to the engine. You mention the hose is cut and appears from the photo it has been so for a while. Is there a sea water pump mounted on the engine? A through hull sea water...

    Lost gearage?

    Don't see anywhere in this thread where someone said you couldn't swap a gen 2 with a gen 2. In fact that is the most pragmatic approach to your initial issue Unsure of why you also swapped bell housings unless the original didn't have the check valve for the gear lube monitor system in which...

    Bravo 3 lube reservoir not draining with outdrive removed

    True fact Will add if you want the lube monitor bottle/lines drained its easiest to do with the drive still mounted to the bell housing. Will drain a majority of the monitor system along with the drive this way

    Removing Shift Assist

    I've seen a few setups where someone has abated the shift assist and used bushings/washers to compensate for the gap. Others that have simply had the springs removed from inside the assembly

    Mercruiser 4.3 oil gauge mystery

    Wouldn't say I was tricked, rather misinformed. Standard electrical guages read from 30-240 ohms resistance. OP method of testing although not necessarily accurate would in most opinions be considered reasonably sound seeing as how both senders appeared to correlate output readings based on...

    Volvo Penta Drive Belt - Lots of dust and quickly wearing??

    How many batteries are you using? Having a stereo system with a large amp drawing a lot of current from too small a source will cause the alternator to over work. I recommend at least one extra deep cycle battery in any amplified stereo setup, most cases two depending on additional house...

    Mercruiser 4.3 oil gauge mystery

    From post #1 Depends on your method of testing. You make no mention of how you tested the sender(s) only that you tested them Also, in regards to your first post mention of the system (guage, wiring and sender) testing okay leads others to focus on other areas that could cause the issue

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

    I find it hard to believe there isn't an anti siphon valve in the fuel system. Have you verified by removing the fuel line from the tank barbed fitting (which is most likely the anti siphon valve) and inspecting? Agree with others as to your issue being fuel supply. You need to confirm the anti...

    Raw water pump

    Is this a bravo or alpha drive? Yes, an air leak will cause raw water supply issues. Your other thread I posted to use a piece of sandpaper on a flat surface and move the pump back plate in a figure 8 motion to rid the grooves and smooth the surface. A belt sander most likely did not smooth...

    Mercruiser 5.0LX Rochester 4MV carburetor over fueling. ESN OF066511

    That clear/yellow line is in place as a safety measure to allow fuel spilled from a ruptured fuel pump diaphragm to be routed to the carburetor instead of spilling into the bilge and creating a fire hazard. If you indeed have fuel present in the line that is why excess fuel is entering the...

    Hard Start All The Time

    1. Distributor no, cap/rotor yes as part of a standard tune up including plugs, wires (if 10+ years old) and fuel filters. Check/set idle timing to spec and adjust carb for spec/desired speed and smooth running. If thunderbolt ignition it's recommended to replace the ignition sensor in the...

    Mercruiser 4.3 oil gauge mystery

    Your setup, if indeed oem wiring should have an oil pressure switch for the fuel pump circuit, a separate oil pressure switch for the audio warning system and an oil pressure sender for the gauge. Based on provided info my guess is there is an issue with the wiring for the audio warning system...

    Mercruiser 5.0LX Rochester 4MV carburetor over fueling. ESN OF066511

    Agree with others, sounds like a stuck float/needle not seating. Good idea to check fuel pressure as well

    5.0 Mercruiser T.I. Spark Plugs

    Being roughly 2000 vintage there should be a letter before the numbers on the s/n tag. When entering the s/n there is a prefix of 0 as well. E.g. 0A616838 or something similar For spark plugs it depends on if the engine is efi or carbureted. For carb the AC Delco MR43LTS would be correct, if...

    Low fuel pressure, fuel filter half full while idling.

    Not always Based on OPs pics I took a shot on removing the mount. Might work that they don't have to go that route Worked on a couple boats that I had to remove the mount, pics looked familiar ymmv
