    1979 115 hp 6 cyl inline 2 cycle timing/carb adjust

    2 things to note: 1: the throttle cable is adjusted to set the idle remove the brass fitting from its holder and turn it until the throttle arm makes the lever hit the idle stop - 2: you have to adjust the low speed in the water in forward gear; set the needles 1 1/4 turns out from seated to...

    90Hp torque spec

    I use a large screwdriver that fits the screw tightly and tighten it hand tight, new washers (fiber ones don't use o-rings) make sure it won't leak.

    5.7L MerCruiser Bravo III under water...repairable?

    You could probably find an abandoned boat on dry land at a marina and fix it up; some people walk away from them and you might get it for just paying the storage bill.

    5.7L MerCruiser Bravo III under water...repairable?

    I don't know what goes on in your area but around here you can't take a boat to the dump you have to pay to have it ground up and disposed of. This costs you money; so if that's the case I'd walk away!

    Motor and power trim swap on 35hp

    If they're identical just swap powerheads - basically removing nuts and replacing the gasket. Take the bad one off first which will give you the plan. I would do the lower and upper seals before installing the new one.

    How's the drive coupler are the splines dry or did you grease them?

    1972 Mercury 800 Thunderbolt won't idle below 1500 RPM .... Please Help!!

    After you've tested the compression try setting the low speed needles 1 1/4 turns out from seated then running in the water in forward see if it will idle down. The idle can be set using the cable's brass barrel - remove the throttle cable and push the lever forward to lower the idle then adjust...

    Mercury 1150 115hp(1977 I believe)

    Someone has put 1150 decals on the trim plate and a front cowl piece from a 1972; the lower unit appears to be new style but the powerhead is pre-Thunderbolt, I see coils and a points distributor - you'll need the 1939-1965 manual and the serial Nr. The distributor uses 2 sets of points but you...

    Mariner 60hp 2 stroke tachometer

    You should buy an alternator driven tach they sell them on this site, they're My tach from the 80's. tougher and will probably last longer; might be more accurate too.

    Check that gearcase for lube/water it looks like it has dragged across something, I would replace the impeller and lube the driveshaft splines.

    Stator electrical replacement question

    Since it is not usable as is take a Dremel tool and dig into the plastic until you find the windings and hook new wires to them, put a spacer between the connections then pot it with epoxy. The winding wires are solid so they should be easy to find.

    40 hp Mercury 2 stroke motor problem

    Just disconnect the instrument power lead from the present ignition switch terminal (which is probably the start position) and connect it to the "run" terminal. You can find this terminal by turning the switch to the first position and, using a voltmeter or 12v test light, touch it to a terminal...
