    volts needed to start 150 Vmax

    Can anybody tell me what is the minamul volts needed to start a 99 150 Vmax if all else is good on the battery? I am running a lot of electronics on my start battery and want to set a low volts alarm on my sonar. Have set down to 11volt alarm but it goes lower than that while cranking. Thanks, Paul

    Motorguide shaft end play

    I bought a used 2005 Motorguide 24v Pro Series 70 trolling motor Runs fine, looks to be hardly used. However the prop shaft has about 1/4 inch endplay if you pull / push. Never seen this much in the smaller MG's I have owned. Is this normal ? Thanks, Paul
