    SOLD 2021 SVHO 1.8L running motor FL 21 Yamaha 255xd

    Engine starts and runs. Note: OEM Stator went bad, it’s been replaced with a different part number and off-brand stator. rpm’s jump at times, not sure if it’s because the stator in the motor is not the correct part number. Selling as is.

    AR230 - Taking on water

    Hello everyone – I have a 2008 AR 230. My bilge pump works but once I engage the engines water starts entering the engine compartment very quick. When I put the boat in the water I do not see any significant water infiltration. Does anyone have any ideas of why water may be coming into the...

    I learned a little about Anti-Seize today...

    I learned something new just now. Adding anti-seize is pretty much a lubricant. Torque specs are for non lubricated fasteners. With adding a lubricant you are able to torque a fastener up to 20% more than you would if it was non-lubricated. I've made up my mind. No Anti-seize on spark-plugs...

    2008 AR210 Port engine chugging

    I've had my Yamaha out four times this year, running great each time. We went out for a 5th time and the port engine is definitely making noise. Kind of a chugging sound. I've replace the spark plugs, made sure the oil is topped off, and even switched the coils to the starboard engine to see if...

    Coil Pack Connecter Replacement

    After discovering a intermittent misfire on cylinder #4, I was able to find that the coil pack connecter on my 1.8 is faulty. Any ideas what replacement connecter I can use and where to get it? Haven’t had much luck in my search thus far. The connecter in question is attached below.

    Engine cranks but doesn’t turn over

    I have a 2018 Yamaha sx195. Before I took her out I cranked her up at home, no problem. I launched her that same day and hung out at our spot. 2 hours later I tried starting her and she wouldn’t turn on. The engine would crank, but wouldn’t turn over. The entire time though while out on the...

    Newbie, have questions about LS2000 and jet boats

    Mechanical in nature, but have not owned a jet boat before! (I know, I know ... what was I thinking!? lol) Have read about doing the Pre-mix conversion (getting rid of the oil tank and all) ... right now, it "may" be an option, as I found that, looks like the oil reservoir is filled with "4...
