    galvanic isolator

    So I popped the breaker panel out to check if a galvanic isolator was installed OEM, and from what I can tell, there isn't anything back there. However, the wiring harness is wrapped tight and its hard to get the panel far out enough to tell. Question being: If I installed one anyway, and...

    7.4l idling question

    the Merc manual for my 1994 7.4L Bravo 3 says the idle RMP while in forward gear is 650. Does the idle RPM in Neutral change, or should that be at 650 also? I finally got the boat to idle / run by adjusting the idle speed screw, and its sitting at about 550-600 RPM now while in neutral. The...

    How long should anodes last?

    Quick Question. If you haven't been following my plethora of "how to fix X" and other problems i've been having, corosion has been a big troublemaker for me this spring. My outdrive has 4 anodes, the two on the trim cylinders, the flat round skeg anode, and the U shaped anode forward of the...

    Need advice / suggestions before I call in the pros :-(

    1994 7.4L Merc BravoIII . Starts with some priming & coaxing when cold. Starts right up with a tad throttle when warm. Will run if i give it throttle at ~1,000 RPM, but if I back it down to 800 it runs rough, and if I back it down any below that it'll die quickly. I just replaced all plugs...

    Had the boat out for the first time this year! But, now that the lower-units been rebuilt, the engine is giving me $h!t. 1994 Merc 7.4l About 1,000 hours on it. Starts fine, but I need to give it some gas in neutral to get it going, which shouldn't be necessary if it's EFI, right? More...

With the entire hull washed, buffed and waxed, and everything else in order, I'm looking for ways to kill time on the boat during the next few weeks until I can put her in, so I've started looking into sprucing up the interior (although, I'm hardly a Martha...

    Annoying Anodes..

    Hey crew, I've got a complicated issue with what should be a simple job. The anodes on my '94 Larson Cabrio 280 are corroded as hell. I've managed to get one bolt off, but I literally can NOT get a socket around the other bolt heads. I was thinking of trying some PB Blaster to see if it'd eat...

    Probably Stupid Question on Anchor Rigging & Deck Hardware

    I've got a 28' Cabrio 280 that I plan to do some overnighting with on the hook. When I purchased the boat this last fall, the anchor was rigged without a chain, only the rode. It was retained by cleeting the rode at the bow cleat in the picture, and the bitter end was stuffed down the deck pipe...
