  • Suzuki DT40 cutting power after a short time

    Hi

    I have a DT40 (1970s). On the last 2 occasions that I have taken it out, after a short burst of full throttle, the engine dies to a very low speed. It will maintain this speed for a couple of minutes and then normal service will resume for another couple of minutes and then it will die again.

    There is water coming out of the tell tale but not peeing out fast. When on flush muffs, not much comes through until you give it some revs. Before I commit to buying the kit, can someone confirm whether this is the impeller failing or not?

    Thanks

    Well, thank you for the hundreds of replies, however I have removed the lower unit and inspected the water pump. The impeller is shot to bits so I am assuming the engine is overheating and cutting the power as a safety mechanism. I am telling you this justin case anyone else has the same problem.
