    Correct Tap to use

    What is the correct tap to use for 1/4" x 28 tapered grease fittings? Should I use a NPT tap or straight wall? I must install several grease fitting in a Bravo OD. Fellow boater instructed how to drill and tap but didn't explain if tap was tapered or not.

    Beware of Marine Surveyors

    Last fall, I was considering buying a vintage Sea Ray, which was advertised in Stuart. I drove to Stuart from Pensacola to examine it along with two other boats in S Florida. I contacted a surveyor and requested that he examine boat for rot, especially in the stringers and stern. I signed...

    Installing hinge pin grease fittings on Bravo 1

    Neither of my Bravo's have grease fittings for gimbal rings where hinge pins are located. My previous Alphas all had them. I can not really tell if these are sealed or not. I have never seen sealed "anything" on a salt water boat. But, these may be special. Regardless, I have to pull ODs for...

    Help! What is this?

    I bought an older SR Amberjack that has been retrofitted with Mercruiser Bravos and 383 Strokers with Thunderbolt 5 ignitions. The AJ has had 4 or 5 owners over lifetime. Past owner couldn't identify what is in photo. I believe it is a motor audio alarm? I believe person who installed TB5...

    Adding radiator stop leak to Mercruiser heat exchanger?

    I have a small leak that I suspect is a hose fitting some where but to be cautious, I had planned on adding a can or radiator stop leak into my heat exchanger. I have total closed cooling with antifreeze/fresh (mix) water circulating through Chevy V8 block and exhaust manifolds. Salt water goes...

    I just installed 2 of these. Vendor was great about providing a replacement after testing the first one's sensor failed. Test: I held butane lighter (after blowing out flame) about 2" from sensor for a full minute but the horn never sounded. Manual states 3-4 seconds and red warning light will...

    Restoring Garmin 2006C waypoints from data card

    Garmin manual implies that you can back up and restore waypoints to a data card. 2 cards came with 2006c when I purchased boat. Top card is "Bluechart." Bottom card is labeled "GMZ502L." I don't have a clue what "GMZ502L" does, other than perhaps it is a data card to backup waypoints. Has anyone...

    Refill Ritchie Compass

    I have a large Ritchie compass that definitely needs fluid added. I suspect it was originally filled with mineral oil, but I am not sure when it was manufactured. West Marine wants to sell me 20 bucks worth of Isophril L, when a couple of bucks worth of mineral oil (which I already have) will do...

    Video on installing MC V8 shaker/woble crank pump?

    One of my 383 stroker crank pumps (raw water) is slightly miss-aligned. It, indeed, wobbles! Does anyone know of a video on how to adjust this pump. There is a lot of hardware in the way for me to totally see all of its fasteners, but it appears to have 3 bolts fastening it to the crank pulley...

    Installing Zinc(s) on Bravo 1 Hub

    Manual is not real clear if I am to add "never seeze" onto SS threads that hold hub zinc onto hub. It seems to me that I am asking for future nightmares as a result of dissimilar metals if I don't coat threads with something. These are small screws and could chemically weld. Any suggestions?

    Spider line cracks in Gel Coat Concerns?

    I just bought a 30 year old SR Amberjack that is in remarkable shape. I had outside and interior surveyed for structural integrity, and I examined boat?s hull for noticeable issues before buying. I knew it had some keel abrasions but I figured that it would be an easy repair. It was. However...

    Using Battery Switches?

    I just purchased an older Sea Ray that has been retrofitted with 383 antifreeze cooled MCs with Bravo1 drives. Owner had 2 battery selectors. He cranked each motor with both switches set to "all." I was brought up decades ago to run battery selectors and motors independently. If, for whatever...

    Bravo 1 Heat Exchanger Issues?????

    I examined boat this past week that had retro'ed Bravo 1 V8s with heat exchangers. An odd thing odd about the boat was that (when cold) the heat exchanger's body was about 1/2 full, but its fluid reservoir was 3/4 full. I have never experienced an auto radiator being "down" with fluid, while...
