    What are your opinions on this boat?

    I don’t know anything about Mercury’s, but this doesn’t add up. Worth $15 to $17k running. Repair is $1.7k. Will take $8k as-is. The owner is leaving $5.3 to $7.3k on the table. ROI on the $1.7k repair is 3.7x at the midpoint. He/she must have an information advantage (i.e. knows more than...

    VP 8.1 Engine overheat and seize

    What do the journals and mains look like? Hot oil is too thin. Thin oil leads to a seized motor. The oil cooler picture says a lot. The walls, journals and mains will also. Question to answer is overheat and seize, then water; or overheat, water and lockup. Rods straight? No thrown rods says a...

    Looking for lower end case: Volvo Penta Cobra SX product 3868389

    For this drive, the lower covers two ratios for 6 of the 8 offered. In your situation, the lower covers 1.66 and 1.97. The answer depends on exactly what new stuff has already been purchased. Are you sure the housing’s bent? That’s a heck of hit, and if it was run post, there has to be...

    Volvo Penta Trim Cylinder Rebuild

    The different cylinder part numbers you list are for the three different trim position limits… full, 42-degrees and 32-degrees. Repair kits are the same. (FWIW. Sorry, the Serial No. isn’t correct; and no idea what the number above Product No. is. Is it possible to post a picture of the tag...

    Looking for lower end case: Volvo Penta Cobra SX product 3868389

    Finding an empty lower will be hard. Luck of the draw so to speak. Fortunately, there are several complete used lowers on eBay and CL. Pull everything out, put your new in. Not hard. Not one-year. Part No. 3855695 or 3855363. This lower is used on a few drives.

    SX cobra out drive crack

    FWIW. It doesn’t appear that drive’s been removed for some time. See Post Nos. 2 and 3. A good idea this Fall to avoid expensive damage later.

    SX cobra out drive crack

    If the question is about the “slot”, it’s on the starboard side and normal for this drive. No crack. No cause for concern. Machined in when originally manufactured. (There’s not one on the port side.)

    New Volvo 250 HP PY20

    Based on bench testing, at approx. 4.8v the sensor alarms. This corresponds to about 112 PSI. Looking at other motors with this sensor and series of ECMs, that’s the high OP trigger. But, I don’t have specs. for your serial number so can’t be 100% certain. I’m with everyone else… OP seems high...

    Need Help From You Guys That Have Prop Efficiency Calculators

    Thank you. I’ll be darn. For kicks and giggles I read through VP’s TDS for this motor and noticed a footnote on Page No. 1 re. EPA… “Approved for limited use”. I then attempted a read through the EPA rule that brought us these catalyzed wonders of over complexity now plying the waters. While...

    Need Help From You Guys That Have Prop Efficiency Calculators

    Non-Cat? If I recall correctly, Cats were a 49 state EPA mandate < 500 HP January 1, 2010 and after. California did the same around 2008.

    New Volvo 250 HP PY20

    Next step… imagine Cats and sensors for lawn mowers. The complexity added to everyday stuff is astonishing. I still remember the first time I learned a PCB was part of a plain, tried and true, natural gas water heater a couple of decades back… not so happy.

    New Volvo 250 HP PY20

    Cannot disagree. Regarding low oil pressure, for this motor, < 5 PSI @ 550 RPM and < 30 PSI @ 5,500 RPM.

    New Volvo 250 HP PY20

    Suggest reading through the following link. It explains the system, and objectives, pretty well. It doesn’t provide the specifications that are sought. I’ll see if these can be learned elsewhere. I did look at sensor parameters for VP’s Generation V V6-250-___-___ a few days back. There are low...

    2005 VP 5.0Gxi 2500-3000rpm max. Low pressure Pump 0 psi

    Spec. is 4 to 12 LP pump, and 50 to 60 HP pump for a 5.0GXi. Suggest taking readings again. If LP pump is indeed zero, yes, the engine is fuel starved and the HP will be hot to the touch and whining when under load (in gear). Needs more fuel than the HP pump can supply solo. Happy flying.

    Power Steering Fluid Change

    Sorry, I don’t know as I’ve never used a transfer pump for this purpose.

    Volvo Penta V8-300CE DP w/cl cool

    Interesting. The anti-rotation bracket broke (it’s the black rod in the second pic). If a bad bushing or bracket, what occurred is a likely outcome. The question becomes what broke first… bushing/bracket or casting. The documentation is helpful and relevant. If not replaced in April, is today a...

    Power Steering Fluid Change

    If I recall correctly, the interval is 5 years/300 hours for a V8-300-CE-B with a joystick. Drain reservoir, “break” a line at the pump, vacuum to pull fluid out or hand pump new fluid through until old is out (color/shade changes and becomes consistent). Clean off reservoir, hoses and fittings...

    Exhaust Temp sensor 3889526 Spec?

    No problem. Where do you boat, north or south? 174-F seems a little warm for this motor (5.7L with Cats, EGC). They tend to run low 160’s if sea water is below 80-F or so and ambient around 90-F. 174-F isn’t hot, but might be a telltale sign. Between this and the exhaust alarm, suggest checking...

    Volvo Penta V8-300CE DP w/cl cool

    The ECM recorded any alarm(s), how they were handled and elapsed time to shutdown. I doubt grim, but whether grim or a few minor things here/there and whether and an easy or difficult warranty claim likely depends on whether shutdown occurred within seconds or it was run for minutes after the...
