    Bravo 3 loss of lube oil - slowly then rapidly x2

    No But it will give you a chance to clean and inspect the entire upper driveshaft housing assy. The only other seals replacable aside from the yoke seal are the shift shaft seals and there's not often failure/need to replace them, everything else is o ring sealed. Also, going back together...

    Perco battery switch install

    I'm not sure. In the picture posted by OP it is definitely not installed as shown in the schematic you've posted which is the correct way I was merely stating that OP's setup is (now confirmed) a Ford base and oem configuration has main B(+) connection to slave solenoid

    Foul Release Coatings ??? PropOne, PropGlide . . .

    I would tend to side with the manufacturers (Mercury) recommendation and apply zero products to the propellers The best method to preventing marine growth on propellers is to use them as intended. Sitting static doesn't do you or your boat any good, ymmv

    WARNING !! WARNING !! About brand new sparkplugs I bought.

    It is standard practice to check spark plug gap prior to install every time even with plugs not recommended for gap adjustment Maybe the packaging was moved violently, dropped, kicked, set on fire, etc...does that mean every new plug out of every new package is correct? No, and it only takes a...

    New to Volvo family

    Yep, SX-A and newer all have sealed/non greasable bearings and no channel/zirc in the gimbal housing to allow for older style, serviceable/greasable bearings. U joints will be permalube/non greasable as well I've read some varying opinions on this forum over the years about Volvo and Mercury...

    Thoughts on New Gen Direct Injected VP 5.3L v8 350HP?

    Have dealt with the GM gdi motors for a few years now and I've seen very little failures in that time They seem to run well and with proper maintenance perform quite well. By far the most issues I've seen is accessories, pumps, alts, starters, etc...What you'd expect with any marine engine...

    There's little to no chance of finding a brand new cable that fits into the helm pictured You're looking at a new cable, helm and possibly steering wheel And no, cable you linked to will not directly replace the current one

    Perco battery switch install

    Bilge pump float switch power comes from either (+) battery post or in OP's case either #1 or #2 post at battery switch Connecting to common would mean float switch would only have power with the battery switch in an "on" position. Needs to have constant fused power supply regardless of battery...

    weird grounding issue

    This is true, hence DC (direct current) the current only flows one direction. From (+) to (-). This is why a power windlass can change direction by simply reversing polarity at the motor connections I think your setup is a bit cobbled and the attempt to switch the ground side is wrong. I've...

    Volvo penta aq125a

    I would think opposite of this statement As rpm increase, vessel speed increases 600-700 idle in gear/minimum wake, 1100 rpm at earliest off minimum wake speeds

    Alpha I Gen II Impeller Replacement

    Not uncommon to see loctite on the fwd most fastener between the halves, mainly for anti corrosion purposes The "seal" on top of the housing is a slinger in place to prevent water wicking up the driveshaft during operation. The new kit (hopefully oem) comes with it The guide piece has melted...

    Volvo penta aq125a

    Most/all decent dvms sold these days have dwell capability. It's not reliable though because the signal is analog (slow/sweeping) and a dvm reads mainly peak voltages. The capacitor in the points system throws the dvm reading off There are a number of reasonably priced analog dwell meters...

    weird grounding issue

    If you installed the switch on the negative/ground cable from the battery then my guess is the electrical system is finding ground through the hull and getting back to the battery (-) post via that route The battery is the main ground for the entire boat and engine 12 volt electrical system. By...

    Bravo 3 loss of lube oil - slowly then rapidly x2

    The bearings/races don't need to be removed from the gear, just need to remove the gear/bearing pack assy from the yoke shaft along with the tapered washer, seal carrier, spacer, o ring, washer and nut You can gently rap on the gear end to unseat the bearing pack so upon reassembly the nut will...

    6.2 MPI Whine noise when revs

    Regardless of last service that whine and apparent rattle in the video denotes something quite off First step is to remove the drive and inspect u joints and gimbal bearing. If okay I'd be suspect of low oil in the drive. Would think the problem will be obvious after inspecting these items
