  1. 305SX230

    MR1 engine overheating only when underway.

    Hi everyone, I could use some advice. I have an 04 SX230 with the MR1 engines. About 2 months back, I took the boat out, and the starboard motor overheated. I looked over, and water was coming out of both of the spouts at the same rate. When I got home, I ran it on the hole, and it would not...

    2021 SX190 - overheat warning but reality seems unlikely - suggestions?

    Hi, have had read a couple of related posts, but thought I would share this specific experience and see what folks think/suggest. Just bought a 2021 SX190 with 25 hours. Great condition with exception of more scratches, scrapes, gouges in the keel than you would likely expect for the few...

    Water On / Motor Off!

    I have a 252FSH and I turned on the port motor, then turned on the water. The hose had a kink and was not flowing enough water pressure, so the motor started to overheat (ran for about 5-6 min). I noticed smoke coming out and panicked so I mistakenly turned off the motor before turning off the...

    AR190 Overheating cause- LectroTab? Impeller? Impeller Housing?

    I have a 2017 AR190 that I have put over 100 hours on it in the last year with no issues at all. We usually run long distances when we are out and there have been several days where I have run two tanks through it in one day.

    Overheated engine

    I bought a new 2019 Yamaha AR210 jet boat with 16 hours. Turn on the engines on the boat being out of the water for about 3 minutes. BIG mistake. The boat's display shows me the message: TURN OFF THE ENGINE AND CONTACT YOUR YAMAHA DEALER. Any idea how serious it could be ? How much would it cost...

If I slow down to 3000 to 4000 RPMs the temperature goes back down to mid 190s...
