    Need advice, 1996 125hp no spark now, won't start

    On your motor, a single stator with multiple windings powers both the ignition and the battery charging circuit. A loose negative battery cable can easily damage the voltage regulator, causing a possible short impacting the ignition. I would disconnect the VR from the stator and insulate the...

    1985 Mercury 115 tower of power

    Part #14 and #17 can rot out allowing water into any cylinder. They can also warp, and make it hard for them to seal. The repair is a real PIA, as you realistically need to pull the powerhead, true up and/or replace the parts and bolt everything up, and then it maybe still leaks. I would...

    Overheating at idle, cool as a cucumber at speed

    The SS wearplate should have a gasket on each side. Put them on dry, and make sure to match the wearplate and housing with the correct gaskets.

    The wire colors appear to be correct. Good luck with it.

    Mercontrol Rewiring

    Purple is the new wiring color for ign power, replacing your white wire. It also needs to feed the choke button, to power it. Other terminals on the switch that you need are battery, solenoid (feeds neutral interlock switch in series), you will likely have a ground on the switch as well.

    OK, so it would appear that you need an ign switch that has an "I" terminal for ign power. Is that what you bought?

    Mercontrol Rewiring

    On those MerControls, Mercury wired them so they will work with battery-powered CDI ignition, as well as ADI ignition. That is, they have an ignition power supply and an ign killer wire going to the motor. The motor uses one or the other. On an 1150, 1979 1/2 was the changeover from...

    Materials

    The hardest part is to find a way to clamp the transom to the hull, while the resin sets. I glassed some pressure treated lumber to the hull, along the deck, and just under the splashwell, so I could screw the transom to the hull, after the glass was wetted out. I also installed the transom...

    slow drop on T&T, 1982 50 hp

    Yes, an internal leak. Consider it "blowby" in the PTT cylinder. The check valves could also be an issue. A rebuild kit usually has them too.

    1963 Evinrude won’t start

    If she didn't fire on ether, you have no spark. Even if the spark was well out of time, she would backfire on ether. Maybe your motor will not spark under compression? I would check the ignition plate for wobble, and make sure the coils are in the correct position on the plate, and the...

    Materials

    Andy, I simply meant that your boat (and the vast majority of boats) are made of polyester resin, plus cloth and mat of the appropriate weight. Cloth comes in 1.5oz, 3oz, 4oz, 6oz, 7oz, 8oz, up to 40oz. Weight is per sq yard. Heavy roving cloth comes as 18oz, 24oz. Weight is per sq yard...

    slow drop on T&T, 1982 50 hp

    Sure, a leaking PTT piston seal will do that. See if you can get a rebuild kit for the PTT and if special tools (ie spanner) are needed.

    Problems with oversized boat motor

    That isn't a Jon Boat. It is more of a semi-vee boat. 12 foot Semi-Vees were often rated for 25HP, so a 14 footer should be rated for 30 or more HP. My 1960 Crestliner 14 foot runabout (also 5 ft beam) was rated for 40HP. You could look up similar boats and see what they are rated for.

    Under seat storage

    How about the correct sized Tupper wear containers?

    Materials

    There are several weights of glass cloth, and a couple of different mat weights. I would recommend you go to a marine store and check them out, and see which has the flexibility and strength you want. Figure on 4 layers of cloth overlapping the hull by a few inches, to finish the inside or...

    Non conventional issues.

    Gee, testy aren't we. So, you have a crack in your airbox, and you are blaming that for poor running? Good luck with that fix.

    Source for mooring chain/hardware?

    The best price will likely be online, maybe even amazon. Galvanized chain with the yearly application of cold galvanizing paint to cover any rust, should last decades.

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    Hitting the primer when she bogs may not help, as you seem to have a fuel delivery issue. No fuel for the carbs = no fuel for the primer. Since you already rebuilt the fuel pump, replace any fuel filters or water separators you find. I always thought 5/16" ID fuel line diameter was marginal...

    Compatibility

    I would post this in the MerCruiser I/O forum. Those guys are experts. However, I am really skeptical that you have correct info on that swap.

    Should the prop have any play

    The prop should not move on the propshaft splines. Movement of the prop on the splines will likely cause damage to the gearcase, propshaft or other parts. The entire propshaft may have some small play, and it is usually normal. 1/8" play in the propshaft is about what I have on my Merc and...
