    Mercury Water Temp Gauge

    Thank you for the information. Yesterday I removed the plastic cover over the spark plugs and the two engine anoles were there but I didn’t see nor was I looking for a brass plug. With the age of the engine I ordered new engine block plugs so when they come in I’ll look for the brass plug or...

    Mercury Water Temp Gauge

    I have a 2003 Mercury 75 HP serial # 0T787481 and it doesn’t have the optional water temp gauge. It does have a horn connected to the thermosensor on the engine. I have the kit 12415A for the install and 12415 temp sending unit. I have 3 sets of instructions and they do not match my engine...

    Electrical Wiring and installing a new transducer

    Thank you for your knowledge and experience. Facing to the front there is a bracket welded to the back of the left pontoon. It comes out about 2” to 3” then straight down about 3” and then back to the pontoon. If I attach the plastic bracket and then secure the transducer, it may or not be...

    Electrical Wiring and installing a new transducer

    In pricing 14/2 for 250’ was $ 11.00 more than 16/2 at 250’. I’m going to go with 14/2. The transducer has a plastic plate which will mounted onto an aluminum pontoon. The transducer then is attached to the plastic plate. It will be about 1” to 2” below the bottom of the pontoon, I believe...

    I am looking at Ancor Marine Grade Products 121525 Duplex Cable, 16/2 AWG (2 x 2mm2), Flat - 250ft for wiring I a new fuel gauge from tank to gauge. Will 16/2 work or should I use 14/2? I also will rewire all lights and all electrical with this wire. Thoughts? Need to install new fish finder...

    Depth finder, fish finder or both?

    I have a 2002 Starcraft 24’ pontoon and it came with a Humminbird Platinum ID 120, which is not reliable. I’m looking for a depth finder which also can be used for fishing now and again. Any suggestions? Thank you in advance. Norm

    Trim on throttle take off to gauge

    My trim control is mounted on my Mercury throttle, is there a way to tap into the wiring to add a trim gauge with my other gauges? Do I need to purchase the wiring kit from Mercury to make it work? Would like to tap off existing wiring setup. 2003 75hp 0T787481. Thank you in advance.

    2003 Mercury 75hp Serial 0T787481

    I made a mistake on my oil change. I have 4 quarts of 10W-30 and 1 quart of Premium Gear Lube installed. Can I run it this way or do I need to drain and install 5 quarts of 10W-30? I have not used the motor with this mixture of oil. Thoughts? Thanks.

    1968 Evinrude 55 HP 55873

    Motor has overheated a couple of times. The external water tube (# 314489) melted and the part slid down into the water intake and caused a 85 % reduction of water flow. Do I need this ext. water tube or will the motor pull cooling water up without it? Thanks, Norm

    Timing for 1968 55 HP Triumph 55873R

    I completed a full tuneup of my 68 55HP motor. It worked well the first day but I had to remove the flywheel for a few adjustments on throttle linkage. Now it will start and run for 10 seconds and stops. I'm thinking the timing is off. Can I bring cylinder 1 to top dead center and align the...
