    AQ131 Ignition Parts from NAPA?

    My 1986 Bayliner Capri 1950 is powered by an AQ131 (i.e., Volvo B230 engine). In preparation for the 2019 boating season, I'm planning to replace all the distributor ignition parts (cap, rotor, points capacitor). Of course, these parts are readily available from Volvo ($$$!) and Sierra($$) and...

    What is the function...?

    A minor point: I recently removed the upper from my 275. Everything worked as described above, except for removing the clevis from the eccentric on the upper. As my photo shows, it was not possible to push the pin in far enough to free the clevis from the eccentric: I had to remove the push...

    "Blown Engine" Update

    Ricardo, I was aware of multiple of your previous posts regarding the exhaust manifold and prior to removing it, I was expecting the worst. I was very pleasantly surprised when I examined it after removal - it was in excellent condition. The pic's are prior to any cleaning efforts. I probed...

    "Blown Engine" Update

    Since it's near the end of the boating season here at lake Tahoe, I thought I would post an update on an earlier post regarding engine trouble with my 1986 Bayliner with AQ131A/275. In early June, after a nice 30 minute run to one of our favorite coves, the engine suddenly quit. We got a tow...

    1986 AQ131 Engine Failure (?)

    Both visually and by the "feel" tests, the walls of all four cylinders are perfect. Unfortunately, the same can't be said for the #4 piston crown:

    1986 AQ131 Engine Failure (?)

    Well, I got the exhaust manifold and cylinder head removed and I didn't expect what I found. The exhaust manifold for all four cylinders was in near perfect condition; no sign of any exhaust blockage issue whatsoever. These pic's tell the tale though: the face of number 4 exhaust valve has been...

    1986 AQ131 Engine Failure (?)

    I took some good advice from johnnygjr and put a boroscope in cylinder 4: It appears the exhaust valve has been dislodged and has been striking the face of the cylinder, the source of the loud knocking sound observed. I'd appreciate opinions on whether the piston damage is bad enough that in...

    1986 AQ131 Engine Failure (?)

    We recently experienced a significant engine problem on our 1986 Bayliner with AQ131/275. During our last outing, after running normally for approximately 20 minutes at 4400 RPM's (oil pressure, temperature, power, etc. all normal), we went to idle for a few minutes. When I reapplied the...

    U-Joint and Yellow dot

    I'm getting ready to reinstall the transmission on my AQ131/275 outdrive. I noticed that on the PDS end (i.e., female end) of the transmission U-joint yoke, there is a prominent yellow dot. There is no corresponding dot on the PDS area as near as I can tell. Does the yellow dot indicate how the...

    AQ275 Steering Assembly Bushings

    I recently pulled the upper gear case on my AQ275 drive to service u-joints, PDS, etc (AQ131 VP engine). I've noticed a slight "wobble" in the steering assembly and with the upper gear case removed, now would be a good time to replace the seal and bushings on the steering shaft,, or so I...

    Proper Drive Parts for 275 series

    My 1986 Bayliner is equipped with an AQ131 engine and 275D drive. I am in the process of removing the transmission in order to service the U-joint assembly, the steering yoke bushings and possibly the primary drive shaft bearing and seals, if needed. My question: I have found separate parts...
