    Adding a Fuel Bladder -- grounding

    The tank ground is there to prove the negative return part for the fuel sender to work. It is not there to control static. I don't see a need to ground the fuel valves. Improper grounding can cause damage to components I should also point out that a bladder is an insulated device and is no...

    Adding a Fuel Bladder -- grounding

    In that case, ground wires on metallic thru hulls and other fittings are advisable. The key is galvanic isolation to insure there are no circular currents.

    Re-adhering Helm and Deck Trim

    The trim was probably installed with two sided tape, There is a 3M molding tape made for trim. It is really sticky. That said, the corners you mentioned are caused by shrinkage and the tension will pull the tape away from the fiberglass over time. I have reattached trim but also relieved some...

    Adding a Fuel Bladder -- grounding

    The small nut you mention is for bonding, not grounding. If you vessel does not have a bonding system installed, fittings should not be connected to battery grounds. The probability of a static spark is generally low since the humidity has a lot to do with static electricity buildup ( on your...

    I didn't think it was AI, I just thought that we as a society were getting dumber. I know I have posted some stupid responses:)

    Grady Stringers and Knees?

    It is hard to estimate how slowly or quickly moisture will travel. There are a lot of variables including the climate the boat is stored and operated in. With respect to a wet transom, 'wet' is not terminal always. The problem with moisture is when it leads to core rot and delamination. Wet...

    Adding a Fuel Bladder -- grounding

    I suggest you contact the manufacturer of the bladder you would use and ask for advice. I suspect that no protection is needed. Grounding and bonding are different systems with bonding usually dedicated to galvanic activity. Incorrectly connecting the two together as well as incorrect bonding...

    Fuel tank idea - comments?

    The reason for the pin holes is corrosion from galvanic activity that is generated when the aluminum comes in contact with another conductive material in the presence of moisture (mainly sea water) as an electrolyte. Often the tanks sit on structural supports, bulkheads or stringers in...

    Why does my 228 have 3 pick up thru-hulls?

    I'm thinking of a model year......... Look up archived brochures for Grady White ( for your year). It may list options

    Autopilot and SeaStar question(s)

    If you say you have already bleed the system and did it correctly(:)) I would then disable the autopilot and see if the skipping (slipping) still occurs. You can also try turning the wheel with the boat at the dock to see if it slips. The slipping can be an air pocket or leaky dirty check...

    Flush Plug 0-Ring

    As mentioned by Hookup, go to Home Depot or the like. It helps to bring the fitting or better yet the old o-ring. If you have twin motors, take the o-ring from the second motor to size the new one if the old one is lost. While there, pick up a small tube of plumbers grease. It helps to apply a...

    Butt crack question

    The seats for the adventure are somewhat narrow and can be a challenge to find options that fit in normal position and also are able to rotate 180 around as the original seats can. In your case, new seat cushions may help but you would have to have them custom made. The original cushions are no...

    First time Grady White owner - Seafarer 228.

    Fir dual axel trailers, 5% is the appropriate starting point. I agree that your current placement of the boat is too far forward. It is common for the aft end of the hull to sit past the ends of the bunks. You bunks are sitting past the transom. The bunks should not run under trim tabs if...

    question about varying twin engine trim and boat list

    Trimming an engine up changes the direction of the thrust and points it downward relative to the hull bottom. In theory that causes the stern of the boat to lift up. So in theory changing the trim angle of an outboard will cause the hull to tilt. In reality the force of the thrust has less...

    Rusty leak from gunwale in Freedom 235

    The three holes on the lower edge of the gunnel is where the screw that holds the bolster in place is screwed in. Normally the screw is inserted into one of the grommets in the bottom area of the bolster into the gunnel. It seems that the bolsters may have been reinstalled a few times, hence the...

    The old style 'saddle' mount blades are more difficult to find especially OEM Anchor. Saddle mount is the type that attaches to the arm using a thin bolt and nylock little nut. If you current blade is a hook style or a pin style, you have a lot of options. but note that automobile replacement...
