    Fuel gauge won’t go below 1/2 full

    I understand what your saying (the fuel gauge goes full to empty as your move the arm) but appears your not understanding my point. Assume you tank is in the center of the boat. (I do not know how long the float arm is) Being in the center, most tanks are not square or rectangular. They are...

    Merc 5.7L TKS Carb replacement with non TKS help

    Agree, I would use the 12V connection coming from the diode, not the one from the Temp switch. In the drawing below you can see that power comes from the oil pressure switch. Remove the diode and find the side that goes hot after the oil pressure switch closes.

    2001 6.2 Merc Skips, Gas Smell, No Power When Cold

    Thanks for the s/n, I'm seeing a MEFI-3 so this can make finding codes a bit easier Your motor has a fuel pressure sensor (item 14) and a shrader valve (item 6) to test pressure. Would like to know what the fuel pressure is https://www.mercruiserparts.com/bam/...31953/5725/100 If you get a...

    Generic Boat Wiring information - Updated Verified

    Looks good, and would say it would be for the standard lead in wires for main harness. Once it goes into the EFI harness, things change. Have also have the 10 pin and 14 pin connector

    4.3 engine wont start

    Motor serial numbers are always best, but Being a 1995 I'll assume its a TBV ignition, and does it have a 2 (Merc) or 4 bbl (Weber) carb? Have you run thru the TBV troubleshooting chart?

    4.3 running hot on one side

    Putting your hand on a exhaust elbow and not being able to keep your hand on one can be as little as 10 degrees. One side will always be hotter then the other, so I' not to concerned. Not the 185-190 Thermostat I am, even with a 160 stat. The issue is the drive pump will move water thru the...

    4.3 running hot on one side

    In this case I think you have a bad gauge or sender. The sender is in the thermostat housing, and didn't you verify the temp reading with the IR temp gun?

    350 MAG won't rev past 3400 rpm, sounds like rev limiter

    I'm sure all parts replaced are in good shape, was just a comment if they were not replaced. Don't know which sensor is in which position. Do assume one is before and one after the CAT. No matter which way I look at it, something isn't right and do wonder why there is no code Sure could...

    Wiring Two lights on one switch

    Yes, stern light (anchor light) is wired using a DPDT or using a SPST and a diode, I vote DPDT or actually ON/OFF/ON switch DPDT Nav DPDT Nav with Diode

    350 MAG MPI high idle and suction noisie

    The hole on the middle should be the air intake for the IAC if it is above the throttle plate. The throttle plate is adjusted so the IAC will be about 40 counts at idle. If there is to much gap in the plate then the idle is higher. The O-ring on the IAC is critical for idle. Is the O ring in...

    What connects to this line and does it have a port which connects to the IAC chamber Edit: That may just be the TPS connector I'm looking for how air gets to the IAC

    Vinyl Painting

    Anyone ever try vinyl primer and paint on seat cushions? Have seen some write ups on it working, but wonder if anyone has done it and it last. Reason for the question is a JD tractor seat. Can buy a new seat which is Black from Grammer for $150, but can only get one in yellow from JD, and...

    Ammo Prices

    Haven't fired my gun in many years, and been looking around at prices for 25-06 120 grain. Looking at 1.50 a round and at those prices, target prices will be minimum. I have a cheap hand reloader which also have not used for years. Hey MTboatguy I know you reload, but know any places I...

    Oil pressure switch

    Unsure of the 20 degree bow down issue, but would figure this shouldn't be an issue. The oil pressure switch does not need to be closed for the fuel pump to run during cranking. There is a lead on the left outside of the starter solenoid (purple/yellow) which powers the fuel pump during...

    4.3 running hot on one side

    Not knowing the serial number it could have had one of Mercs "special" drain systems, yours doesn't so all good. Your cooling system is pretty simple, so if the thermostat, hose, connector, mans, elbows and have used the correct gaskets then it should not happen. This is Bravo drive Suggest...

    1979 MCM 260 Impeller Kit Part #'s and Timing Question

    The old drawings are not very good. The thin cork goes in first, then the thermostat, then paper one with the slot on top. Water flow needs to make it past the thermostat (square hole) to keep water in the manifolds. The cooling systems work but most all would be better off converting to newer...
