    if you go the lipo route make sure to have a fire extinguisher handy๐Ÿ˜Š. But in all seriousness be carefull with lipo on both charging and discharging.
    I use gelcell batteries for my 42" tug for the weight I need as ballast. I still need an additional 18lbs

    Thanks Harry. I will investigate your suggestion with the motor combination. If I went that way I will need to double check the ballast of the boat.

    One advantage of the heavier batteries is that they do assist in that manner. The same with the Sea Commander that I rebuilt. I use a gel battery in that which has the weight to perfectly balance the boat. Big downside is the limited time duration on the water.

    Hi Peter
    I think Banggood Surpass Hobby C3542-1250kv or the 1450kv which have 5mm shafts.
    Drop the batteries too much weight, a single 3S or 4S Lipo
    about 4000mah is about 400 grams.
    Brushless car ESC to handle up to 4S Lipo batteries.
    Prop size 35 to 40mm.
    I have use these setups on a number of my boats and all work well.

    I am thinking about taking the plunge and replacing my 750 motor and 240aH ESC currently fitted to my Baby Bootlegger. (Recommended motor for the boat.)

    I fitted the boat with two 5,000 NIMH 7.2V batteries in parallel however would have liked to have them in series to give that extra grunt.

    Any suggestions on what size motor would be the best for the boat would be appreciated.

    Thanks
