    272 Sailfish with yamaha ox66 225's (2 stroke) and 200 gallons of fuel

    1.3 mpg is reasonable for your boat and if if you keep to the 1/3 safety margin, that trip would be reasonable Weather and sea conditions can affect your fuel burn rate. So will load, like gear and passengers Although you have a 200 gallon tank, you won't be able to use it all if you had to...

    265 Fuel sender

    In the US, the fuel senders for boats are somewhat standard at least as far as mounting hole pattern and resistance range from full to empty. There are for the most part two types of senders; swing arms which have an arm with a float on the end that rotates a potentiometer as fuel level...

    Sea Star Steering Troubleshooting

    Is the steering hard when turning in both directions or a lot more in one specific direction? Your vessel is a single motor correct? What model is the motor? The Mavi kit you mentioned is rated for smaller motors, 150 HP max

    gulfstream length on trailer?

    The only way to know for sure is to measure the boats length from the bow eye to the end of the motors. To that you have to add the trailer length from the winch bow rest to the coupler. You also need to take into account the length of of the motors off of the transom when the motors are in the...

    Fuel Tank Replacement

    I use to figure that a decent price for potato chips was about 25 cents an ounce. So on 'sale' an 8 ounce bag was a decent purchase at 2 bucks. This week the 'sale' potato chips were $3.50 for a 7 1/2 ox bag.. That works out to almost 47 cents an ounce. The increase over the last few years in...

    Additive to gas tank

    I only used stabilizer for winter lay up. I do however use a carbon reducing additive (Ring Free or similar when ever I add gas). I have 2 strokes and I feel that the carbon reducing product is important. For 4 strokes, I would be less inclined to use it especially with the price today for...

    Hoping for lift advice - 208 Adventure

    If you used the Grady chart for the stringer spacing, those numbers are not the distance from port bunk to starboard bunk but rather are measurements from the centerline of the bunk to the keel. In effect the bunk spacing would be twice the number or in your case 30 inch spacing or 58 inch...

    Charging a battery

    When I am just about finished closing up the boat after a trip, I press the horn switch. If the batteries are off , the horn will not beep.

    No power

    The whistle you mentioned when going over 5000 revs is probably an alarm. That is something to look into. My first thought was an over rev condition but that shouldn't occur at 5000 or 5200 revs. On another note, I did wonder if trim tabs were deployed but figured that was checked. I agree that...

    Windless wiring help 265 Express

    Did you install the solenoid in the anchor locker or at the helm? What gauge did you use for the power feeds? ( Did you maybe use the 10s for power and something else for the solenoid control wire?)

    GW stern ladder weight rating? 2021, 235 Freedom

    I use my ladder on land all the time. The rating is for the dead weight. If it were rated to account for the buoyancy there would be two ratings, one for salt water and one for fresh:) Also note they you weigh more wet than dry! All that aside, the ladders themselves are what is rated and not...

    No power

    If it were a spun prop or a somehow slipping gear box, I would expect the motor to be able to rev higher. The fact that is revs up to 5200 and stops also tells me the prop is not experiencing a high slip rate. It sounds like the combo of boat, motor and prop is out of horse power. The prop...

    Persistent water intrusion in fuel 19.5 tournament

    Regarding the 3 psi, if your tank was 2 feet wide by 3 feet long, the area is 864 square inches. Multiply that by 3 pounds per square inch and you will realize that the total force applied is 2592 pounds! In addition, 3 psi is the ABYC spec for certification. I am not familiar with the filler...

    Charging a battery

    The rule is to not switch past OFF when operating the selector switch. So 1 to Both is OK, as is BOTH to 2. I would start on the good battery and assuming you are going for a run, switch to BOTH then to 2 for a while. Running on BOTH with one dead discharged battery can actually drain the 1...

    265 express cabin access plexiglass

    You can find 'super' like glues made for acrylic to acrylic applications on Amazon. If there is the space, an added thin strip of acrylic along the entire length of the hinge edge could add extra strength. Ideally you would want to add it under the lid if space is available or it could be...

    No Hot Water in Sink

    If the faucet is a residential model you probably can find the part at a decent plumbing supply. If the faucet is a marine/RV model, that will be harder to find. You will need to know at a minimum the manufacturer. Many Grady faucets were made by Scandvik. Their catalog is available online where...

    No power

    When you tried to accelerate did the revs go up quickly or did they struggle to increase? Could you have gone more than 5200 revs or was that as fast as the engine would rev to? I assume that the boat never got on plane. Is that true? Is the hull relatively clean?

    Persistent water intrusion in fuel 19.5 tournament

    There may be an anti-siphon valve on the pickup connection. That may block air from getting into he tank. You nave to also close off the fill and vent lines. You may be able to do that by sealing off the fuel fill hole. Finally do not exceed 3 psi. It is not all that hard to overpressure and...
