    Volvo AQ131D cruising speed

    Even carb choice influences fuel consumption, combined with driving habits. A 4 bbl like the Quadrajet with the small primaries and large secondaries will be as economical as a 2 bbl or even more so as long as you stay out of the secondaries. I think on mine they start to open above 4000 rpm so...

    Volvo B20 AQ130 Water in Oil

    that water was in there a LONG time, the cyls are very pitted from the pix, not sure if you can save that one. I had salt water in 2 cyls for about a week, drained the water out and changed the oil like 3x, to save it. it looked like this when I took the heads off to fix the blown head gaskets...

    Volvo AQ131D cruising speed

    The 75% of redline rpm works for most engines. I run my 4.3 V6 at 3600 rpm on plane, that works out to only about 25 mph, but fast enough given the cost of fuel. Most times due to water conditions, wind, boat traffic etc you can't really go much faster safely at least.

    Volvo Penta AQ131D getting hot

    I think 200* is still too hot. Did you do the clear hose test? If the engine has a heat exchanger it should run between 160-180*; if raw water cooled about 160 at most. If it has a heat exchanger as many of these do it may need to be cleaned out. I think that hose connector on the outdrive may...

    Replacement Oil Filters

    remember that the 4.3's filter mount is smaller than the 5.0/5.7. So your typical Chevrolet small block filters won't fit. the gasket OD on the 4.3 filter is 2.73" (69 mm) whereas the 5.0/5.7 one is 3.44" (87 mm). So if your engine has the filter on the block, search up the Wix catalog and get a...

    Dealing with bogging for too long and need help because I've done just about everything!

    I have heard many stories of this EFI system acting up & being difficult to repair. When our cars had carbs they didn’t run as well as EFI esp after a cold start but they were repair-able! With old boats & GM marine engines I prefer carbs, less failure points with respect to wiring and much...

    SAFETY ALERT: Bow Seating Hazard (Malibu)

    Some of those wakeboard/ski boats have a very low bow design that is just not good at all for rough water. Compare that with an off shore style Center Console or even a DC. Personally, I'd rather have a closed bow with a way of getting up to the front of the boat for trailering/mooring. Flip...

    Replacement Oil Filters

    the 4.3s use a smaller diameter filter than the 5.0/5.7s you could use a Sierra marine filter or an auto application for that engine like a Purolator or Wix... The Merc and Sierra filters have gotten much smaller over the years, they are easier to install in a tight installation but not sure if...

    New Boat Launch Ramp

    Ours is getting replaced too, the concrete slabs etc has been sitting there for a while, no idea when they will start/finish, if it's on-going when I pull my boat in a few weeks I'll have to drive over to the town ramp which is much nicer, deep with docks right there. Here's the old one, it is...

    what do you see wrong with this picture?

    If this boat didn’t have a remote filter mount there’s no way you could change it the way the boat is designed. Modern boats scare me!

    what do you see wrong with this picture?

    My brother has a 2020 Merc 4.5 with the same design filter & it doesn’t make a mess when changing it. A little leaks out but not much.

    Water on top of Intake Manifold

    While water can drip down from the engine cover on to any part of the engine; if the gasket doesn’t seal or the bolts not torqued 100% you will see a leak on one of the 4 corners of the intake. Remember the rear ones are closed in the intake but open on the cyl heads. Front is open on both...
