    In my attempt to have my temperature alarm working I found the senders wire was missing. When I removed the two head bolts securing the temp sender I found the bolts pictured full of carbon or black soot. So my questions are many but start with how did theses bolts get a carbon build up on...

    Mercury 1977 200HP with exteral Trim/Tilt motor inside boat mount.

    This thing will not fit under the floor on my 22 foot Aquasport. Actually I might be able to fit it if I cut a fair size access hole and put a access hatch in. There are two access hatches close by already and I dont think a third in close proximity is a good idea. I would rather run the...

    Can the Yamaha binnacle control be used for a Mercury outboard. The wiring will be seperate. With the SX33 universal cables can or does this work? I have a Yamaha top mount binnacle I prefer to use rather than the old Mercury control box.

    Evinrude 150 EXEOM Trim Tilt motor.

    I am looking to purchase a trim tilt motor for the above motor. The OMC number is 4344495 . In the past I have purchased an after market motor and installed it.

    Yam F150TXR 0406 Gear shift handle assembly rod removal.

    I am trying to remove my oil pan on this motor. This shift rod #20 on the Control parts diagram needs to be removed. The manual basically says to remove it but does not go into detail. It looks as though removing the circlip #24 under the bracket #25 may allow the shaft to come up or that...

    1965 Mercury 9.8 forward is reverse

    A freind of mine dropped off an old Mercury red band 9.8 short shaft and asked if I could get the lower unit back on and get it running. It runs badly but a carb clean should take care of that , it has a nice hot spark. The lower unit went on after fiddling with the shift shaft lining up. The...
