    Trolling Motor Outlet and Plug

    I have a problem with my trolling motor, and I am hoping it is the plug or outlet. It was previously working. I started checking the voltage at the plug, and have 27 v, but I think it is in the wrong location. It does not match the plug wiring. Can the outlet go bad I attached a couple pics...

    Do your locker locks have matching keys?

    I bought a 1998 Alumacraft Trophy last year, and all of the lockers have locks on them. I have a key that fits them, but I can't lock or unlock them. I was going to pull one and take it to a locksmith to have keys made. Would all of the lockers have matching keys? Should I just take all of...

    Replacing well used prop

    Here is what I have. Alumacraft Trophy 185 with a 1998 Mariner Optimax 135 hp. I am running an alumimum Black Max 14.5 x19 prop. Hole shot is great and I run about 41-42 mph at 5600 WOT with 2 or 3 in the boat. (I think WOT on this motor should be 5000-5600) The original prop has seen better...

    Lowrance Transducer, Humminbird Unit

    I bought a nice used trolling motor, but the guy I bought it from ran the transducer cable up through the shaft. Problem is that it is a lowrance skimmer transducer, and was hooked to a Lowrance X50 unit that I do not want to use. I have a Humminbird 747c that I have been using, and would like...

    70 hp Merc Vibration

    I have '89 Mercury 70 hp motor that I bumped a stump with at 5 mph last fall and bent up my aluminum prop. Put a new prop on it and took it back out. I notice a very slight vibration at low idle when in gear. Go any faster and it goes away. I have really looked at the prop shaft, and I don't...

    Prop Suggestion

    I have yet another prop question. Here's what I am working with. Had a Michigan wheel 12 3/4" x 21p aluminum prop on a 1989 70hp mercury with t/t. That is on a 16' sylvan aluminum deep-v boat with console. Bumped a submerged stump just at low speed(5-6mph). Broke the prop. The boat had ok...

    9.9 Tohatsu Wiring

    I have what I believe is an '85 Tohatsu 9.9 hp motor. M9.9B 355A 98187. It has 4 wires that are not connected that should go to controls. There is a white, black, and the other two might be brown and tan. How would I connect these to controls?

    Tire wear

    I have a Yacht Club single axle trailer that I haul a 16 foot aluminum boat with a full interior and 70 hp merc. I am having a problem with the tires wearing on the inside of each of the tires. The axle seems to be straight with the trailer and it trails ok. Could it be possible that my axle...

    Raising Motor Position

    I have 70 hp Mercury on v bottom aluminum boat. With my current setup the engine creates a bunch of drag because the AV plate is 1" below the hull line. The holes are about 3/4" raise each, so I am thinking 2 holes higher. I don't have a hoist to lift the motor. I do have other tools and a...

    89 70 hp Merc Charging System

    Would a 89 70 hp Merc. have a standard battery charging system? The reason I ask is a bought a 75 hp motor as a parts motor and there seems to be another electrical part mounted that I don't have on my 70.
