    Pouring Pink into hoses. Raw Water Pump concern?

    winterizing my boat this year. I've got a 99 270da with a raw water cooler 454 MPI with a bravo 3, which means my water comes in through the outdrive, through the engine mounted raw water pump, through an oil cooler, power steering cooler, and cool fuel, then into the thermostat. I see a lot...

    Boat is taking on water somewhere slowly..

    You really have to isolate it first. Put her in the water, dont turn on the motor, and take your flashlight and look everywhere for water. If you're getting 2 gallons every 30 minutes, you should see a fairly steady leak if its not engine related. If you keep it in the water for 30 mins and...

    Steering Wheel Shimmy at low speeds

    This might actually make total sense as the last time i went out, i had a bit of tan sandy/coffee colored water in my bilge. I thought it was just dirty water from when it had last rained and some got in the bilge. Guess its time for me to check the power steering system ugh.

    Steering Wheel Shimmy at low speeds

    Feels totally normal on plane. Just weird to never feel any weird vibration/shimmy/jitteryness in my steering wheel before, and have it show up randomly

    Steering Wheel Shimmy at low speeds

    Took the boat out yesterday and everything seemed totally fine. Started her up to head back, no weird engine noises or any noises in general, but as we were heading out under low throttle (no wake speed under 6mph) the steering wheel had a weird shimmy every time i turned it. If i was just...

    Absolutely frustrated with this Mercruiser engine

    99 270da here (9.5ft wide beam) with 7.4L MPI and BIII with 22p props. My WOT Rpms is 4200-4300 and top speed somewhere around 35-36mph depending on how clean the bottom is. Hopefully that gives you at least a little reference as to what you're looking for

    Mid-90's 270 Sundancer Thread

    Stick to what the serial number recommends. The next years moved up to MPI. We have a 99 MPI and its 160 as well

    Mid-90's 270 Sundancer Thread

    Actually scratch that. I didnt see you have carburated not MPI. If i remember correctly based on previous posts, the 160 thermostat is for EFI/MPI, and the 140 is used on the carbureted 454s.

    If you have raw water cooling, 160 degrees is the OEM thermostat. The 140 is for closed cooling

    Diagnosing Windlass Issue

    Ended up 100% being the control box. Replaced with SPA20697 which is the updated replacement and it fired right back up. Just need to tidy up wiring and I’ll consider this one solved

    Adapter for electrical terminal size

    I’m going to have to go this route, but I was trying all other options because the amount of lead I have left is minuscule so if too much goes, I can’t reach the control box anymore But, this is what I’m gonna have to do

    Adapter for electrical terminal size

    Problem - I’m replacing my windlass solenoid control box, and the obsolete version has M14 nuts for the positive terminals and M10 for the negative terminal. Newer version replacement has all M14, which means my negative cable’s ring terminal is too small to fit over the post Solution - I can...

    Diagnosing Windlass Issue

    As i'm researching this, stupid me missed one of the most obvious ways to test this. Pull the source 12v large cable off the control box, and instead of touching the M1/M2 motor terminals, touch either one of the terminals at the control box, which would in effect bypass the control box. If i...

    Diagnosing Windlass Issue

    99 Sundancer 270da. Need some input here on people who have worked on their windlass. I have a Lofrans Marlin windlass that was giving me trouble last season, but seems to have quit all together this season Last season, the up function was intermittent. Sometimes it would respond no problem...

    Alternative to ShurFlo water pump

    Looking like its getting close to time to replace my ShurFlo fresh water pump. It wont shut off once i turn the dash switch on, and I havent found any leaking lines, so i'm thinking its the pressure switch. Its fine for now since i can just turn the switch on and off when i need to use the...
