    4.3L MPI 2007 Searay Sport 185. Single Alarm at 20 RPMs and higher

    All efi engines have a diagnostic plug to read faults and engine management data. Judging by your experience the fault is critical enough to trigger guardian mode and reduce available power to idle speeds

    Volvo Penta 5.0 GL-B does not go properly

    Sounds like your battery is toast. Have you load tested it? Good idea to replace the dust cap/rotor, they look nasty

    No beep when key turned

    Most likely they are related. Sounds as though there is an issue with the key switch/wiring You can ohms test the switch to see if it is failing

    Why is my carb oxidizing????

    Do you have enough vents in the shrink wrap? Adding a desiccant or two can really help with moisture over winter lay up

    2002 Volvo Penta 5.7gi-b engine overheating

    Looks perfect and performs properly are two different things. Even though the impeller looks okay it does not mean it works okay. Often times the impeller has a set that causes it to not pump enough water to cool properly, this is especially true of aftermarket impellers. Is the drip from the...

    Shift interrupter operation and adjustment after restoration

    I find it odd that you've spent nearly $17k on this restoration yet you refuse to spend $500 for the proper, safe ignition component. This decision could cost you much more than that. Did you follow the merc troubleshooting guide for the thunderbolt ignition system? While the module can fail I...

    2002 Volvo Penta 5.7gi-b engine overheating

    Not likely, most likely the sea water pump impeller has failed and needs replaced

    Shift interrupter operation and adjustment after restoration

    You can test the operation of the interrupt switch with the boat still on the trailer backed into the ramp. There must be a load on the prop for the switch system to operate properly. You will never simulate the correct load with the boat out of the water. Check the stickies at the top of the...

    Temperature gauge issues? Can't get a temp reading?

    This "backyard" repair would not only eventually fail, it would look terrible and let everyone who sees it know that OP does not care about or respect the intended design and operation of the system. So many times I come across items that are improperly repaired that it begins to make things...

    Temperature gauge issues? Can't get a temp reading?

    Your issue could well be a grounding problem. One thing you can try is to clean all the red sealant off the threads and install the sender. Mark the threads where they stop flush with the housing. Remove the sender and apply sealant on half the threads closer to the exterior (stud end) of the...

    Help with vibration from 1400-3500 RPM

    You can add shims under the mounts as needed but this could be an indication of stringer rot. Wood is an okay material but it will crush/sag over time. Better to use aluminum bar stock or a dense plastic material that will hold up better over time

    Volvo Penta oil pressure sensor

    Some engines have two oil pressure senders. One for the gauge (sender), and one for the warning system (switch). The sender for the gauge is normally shaped like a bell, roughly 2" diameter by 2" tall with a small stud on top for a ring terminal at the end of a light blue wire. This is for the...

    Mercruiser 3.0 No Spark issues

    Don't hear the pinging in your video, but videos can sometimes not do justice. Maybe try one with the engine cover off. Pics of plugs look meh, little lean and maybe a bit hot. Second pic shows debris/staining on the porcelain, may be cause for concern if you are detonating could be piston...

    Volvo 4.3L GXI-F Cam/Crank not lining up

    Mercruiser 5.0 Oil Pan Replacement Tips

    1. Mercruiser. No 2. Fel pro/Victor Reinz 3. If yours has rails, clean and reuse 4. Up to you. Interlux Bilgekote 5. 1/4-20 bolts, 5/16-18 studs/nuts in the corners. Again, up to you but if me I'd clean and reuse if not damaged As others have said, pull the motor completely and mount on stand...

    Volvo Penta 5.0 GL-B does not go properly

    Would account for the rich running condition, though doubt the engine would idle well which OP says it does. Need to verify operation nonetheless. Would definitely change out the nasty dist cap/rotor along with plugs, wires, and fuel filter(s) OP, in order to properly check/set timing you'll...

    Winterize questions

    Sounds like OP's engine has the single point drain system with plugs on the seawater pump? If so, OP, the process you describe in your first post will work. Remove single point drain plug ( lower most blue plug in the gray ball housing port side bottom) and both plugs on the sea water pump. You...
