    Removing old water lines

    Just a guess, how about either goo gone or goof off?

    Gas fumes.

    Find out if your tank is foamed in. If you have a leak and no gas in the bilge there are most likely bulkheads surrounding the tank. You said "Getting gas fumes in the center console", do you mean cabin?

    have you talked to the mechanic you bought the boat from?

    Ballast resistor? why

    Isn't that what a condenser is for? They're just a capacitor that absorbed the rapid spike in voltage to keep the points from arcing. I'm going to read up about ballast resistors, I may as well learn something today.

    Ballast resistor? why

    I haven't heard of a ballast resistor but to measure the value of a resistor you need to remove at least one lead from the circuit but you need to know what the value should be. Does the manual state the value of the resistor? Do you have 12v between either side of the resistor and ground...

    2013 Yamaha 25hp 4 stroke running hot

    Start with replacing the water pump kit and check/test the thermostats. Any idea when they were changed out last? How was the stream of water from the pisser? Then track down the leak.

    Electronics die when cranking engine

    You said "checked prior and both of them at 12.5v Weird'. If the batteries are connected in parallel ,+ to + and - to -, or with the switch in the both position, you'll read the same voltage since you are reading them as one battery. If you have any connections that are "a bit eh and loose at...

    Electronics die when cranking engine

    I also have two batteries but have two switches, 1 switch for accessories 1 switch to the motor. You don't want your electronics connected to your starting battery, they're turning off because of the voltage drop when you're starting your motor.

    1st Boat/First Thread/First Everything lol. Need help

    " Approach a dock or landing only at the speed which you are willing to hit it." So true tpenfield. I use windy.com & noaa for weather. I have a mental check list from the time I connect the trailer to my truck until I get home and disconnect it. Make a written list until you get the hang of...

    Starting Problem

    If you have a jumper cable connect one end to the pos of the battery then touch the other end to the starter and see what happens.

    Leaking Shore Power Cable

    Did you set the ohm meter on the highest resistance scale then measure between each wire? You should read an open or OL depending on your meter.

    1st Boat/First Thread/First Everything lol. Need help

    Since you're being introduced to a lot of firsts I suggest you make this one of your first firsts https://www.uscgboating.org/recreational-boaters/boating-safety-courses.php I have a Yamaha F150 on a 21'6 boat, I've had it up to 40mph with no problem but normally cruise at 25. Be safe and...

    1986 Yamaha 25hp doesn’t run good under a load

    When I asked about the primer bulb I should have been clearer. By asking the condition it's in I should have asked if it's puckered as in sucked in or compressed or hard when squeezed or soft where you're able to pump fuel thru it until it firms up.

    1986 Yamaha 25hp doesn’t run good under a load

    OK now I'm back to my original guess that it's a fuel problem. What condition is the primer bulb in when the motor bogs down? Are you running the motor on a portable tank? If so have you run the motor with the gas cap off or confirmed the vent is clear?

    1986 Yamaha 25hp doesn’t run good under a load

    When he said he "squeezed the primer bulb and it took off and the rpms sounded right" that made me also think it was a fuel problem and suggested he check the vent and open the gas cap. Question to the OP, why did you replace the fuel pump, fuel lines, coil and clean the carb? Did you have the...

    Starting Problem

    When you said "I turn the key and got a reading of 13 volts" is that voltage reading while the key is in the start position (second position) and not just the first click "on" position?

    1986 Yamaha 25hp doesn’t run good under a load

    You want to do the prop test with the boat in the water, that's the only way you'll have the full resistance of the water and boat on the prop and hub. Do you know if your prop has a shear pin?

    1986 Yamaha 25hp doesn’t run good under a load

    Check the gas tank vent, is it open and clear? If you use a portable tank pop the gas cap open and try it. When you tested the prop as Sea Rider suggested did you do it in whatever body of water your boating in? The reason I ask is because you tested it and replied the results in less than an...
