    Is the best way to repair this on the bottom of my Hull

    Marine-tex will be the toughest and best of the items mentioned, but it takes longer to set and is harder to work with. Make sure to sand and wipe the surface of the repair with acetone to clean it up. If you plan to use Marine-Tex, mis it with the hardener, trowel it on, and let her sit until...

    Fuel connectors

    Remember not to use a shop vacuum (or any vacuum) to remove gasoline or debris inside the tank. Vacuums have exposed electrical brushes that arc, and often cause explosions when used near volatile fumes.

    Tower of power polished cowl wrap.

    Aftermarket decals are available on ebay and amazon. You could get OEM style or put together a custom look. The nasty brown decal can come off with a heat gun and putty knife. How about a nice white or silver "Mercury" on the black wrap cowl?

    88’ 135 Mercury Blackmax NO SPARK

    Fix your flywheel position. See my other post. If spark doesn't return, you could have a bad switchbox. They are best replaced in pairs.

    88’ Mercury Blackmax 135 HP

    The flywheel is easy to put back correctly. Remove the top most spark plug. Turn the flywheel until that piston is at top dead center. Look at the timing mark. It should indicate TDC. If not, and it is off by 360 degrees/6 bolts = 60 degrees, remove the small bolts and reset the flywheel to...

    Ablative paint hull prep

    You can put ablative antifouling paint over non-ablative paint or ablative paint. You cannot put non-ablative paint over ablative paint, or it will fall off.

    Fuel connectors

    You could remove the fuel level sender and have a look at the inside. You need a ground wire on the fuel sender tang for both safety and to make the gas gauge work.

    Ablative paint hull prep

    Ablative paint is softer than non ablative paint. So if the non ablative is ready for painting it will work. Is the hull painted with an epoxy coat? If not check for blisters in the gel coat before painting. If no blisters, and the boat has been in the water for a season, you should be good...

    Looking to repace my plexiglass wind shield

    Years ago I wanted to fabricate a plexiglass windshield for my speedboat. There was never any from the OEM. A guy from a plexiglass offered to heat and bend a piece of plexi around a mold that I made. I never did it, b/c the windshield would be twice the height the of my boat.

    Near new old 1996 Mercury 115

    More states are legalizing drugs these days. That is the only explanation I can come up with, as those people must have been high.

    Tower of power polished cowl wrap.

    Gee, I like 'em black, with the pretty decal colorings. I never did like the brown color, but the blues and silver and red are pretty.

    88’ 135 Mercury Blackmax NO SPARK

    Batteries do not produce spark in that motor. Spark is created in the stator, amplified in the switchbox and pulsed to the coils when the trigger fires. I would check your wiring. It needs to be clean and tight. The black/yellow wires to the switchboxes (there are two on top of one another)...

    Fuel connectors

    You can also buy another fuel line like you have and remove the upstream fitting, and slip the hose over the hose barb in the existing main fuel line. I do agree that you need to inspect the main tank. You will not get far with a 100HP motor and 6 gallons of gasoline. You will want 18 gallons...

    Fuel connectors

    I presume you will use the built in tank the most, and the smaller tank as aux fuel, or transport of fuel from gas station to boat, right? If so, you can use the short fuel line when you use the small tank. Primer bulbs are pretty cheap. If you plan to siphon fuel from small tank into main...

    90hp merc slight bogging

    Idle mixture needles only affect engine at RPMs of 1200 and less. Low RPM of engine needs special, richer mixture than high speed operation.

    Prop size

    One more thing. Run boat at WOT with normal load and max trim and then record max RPM.

    Homemade C.D. unit to replace discontinued

    I expect the hard part of your task would be to rig up the trigger. There are likely lots of CDI units for autos and other applications Years ago (1970s) there were aftermarket CDI units. They used points as the triggering device, and zapped the standard automotive ignition coil with 300V or...
