    trailer manufacturer picks?

    for salt water, it must be galvanized. Painted steel will rust and you won't be able to do a thing about it, no matter what you try. Load rite is pretty popular around here.

    Broken leaf spring

    Sure, leaf springs break all the time. Usually they get all rusty and look like that have a kink starting. Replace it with the same kind or maybe a bit heavier. They are available on the web at east coast marine and other places.

    1993 50hp merc oil injection issue

    Right, the oil reservoir gravity feeds oil into the pump. The pump then pushes the oil thru a Y into the gasoline line. You might disconnect the pump output line and run the motor on premix and see if she pumps oil. Some Mercs have a plastic gear that drives the pump. These fail over time...

    Mercury outboard 150hp blackmax timing

    Obviously at TDC the timing pointer should read TDC. You are supposed to Set/check the timing pointer. Do you have a .464" mark on the timing decal? if so, set the #1 piston to TDC using a screwdriver. Now measure from cylinder head to top of piston. Add that measurement to .464 inches...

    Dead Battery

    Stereo systems often have a "always powered" connection to the battery for their "keep memory alive" for radio station presets. I would not expect this to have that large of a drain, but that could be part of it.

    1993 50hp merc oil injection issue

    You might have this moved to the Mercury repair forum. I thought those oiling systems were gravity feed, from the tank on the engine. They should easily bleed, I would think.

    Dead Battery

    Yamaha owners manual says that motor has a 25A charging system. That charging rate is likely at high RPM, and the charging tapers off as the battery is charged, so 3 hours would in the ballpark to charge up from near dead. However, a Dingbat says, the battery is likely on it's way out, now...

    Dead Battery

    Was it moored and you had lots of rain? The bilge pump ran the battery dead? If no obvious drain on power, something is amiss.

    90Hp trim gauge reads backwards !

    I do not think so, but it is not solving the problem. The real solution is that either you have the sender installed backward, or the gauge and sender are incompatible. You might consult the specs on each and see what reading zero ohms is supposed to give. Then do the same for max ohms.

    90Hp trim gauge reads backwards !

    Well, the only other alternative is that the trim sender is installed incorrectly. Not sure how that would happen. You could reverse ground and power at the gauge. I would think that would work...

    90Hp trim gauge reads backwards !

    Are the power and ground wires switched on the gauge? Did you switch them on the battery?

    2005 Evinrude 175

    Zinc Chromate is the best for all aluminum. I have used self-etching primer which is avail at home stores. It is pretty good. If you want a good job use a some Rustoleum marine enamel and spray it. Otherwise, rattle cans work OK.

    Fuel gauge / sender….weird issue

    When the engine is on and the gauge is pegged, you are just sitting in neutral? If so, the engine charging voltage may be affecting the gauge. Make sure the grounds are good, and the sender wire is good as well. Of course, if the boat is moving my fuel gauge shows different readings as most...

    Solar Power Installation . . .

    Gee, 100W max is not much for 7 batteries. That is a bit over 1A each in full sunlight. Can you increase the wattage? What was the cost of the system?

    Durable Paint for My New Boat Deck??

    How about making the gel coat non-skid? It is a lot tougher than most paints.

    2006 Yamaha SX230 Hard Initial Starts

    A lot of EFI motors run the fuel pump when the key is first switched on, to pressurize the fuel system. You can hear it run. So with the motor cold, turn the key on, wait a few seconds and then crank the motor to start. If that fixes it, you know what the issue is.

    Control lever removal?

    You might look for a manual for it, if you know the brand. The ones I have had, either had to have the throttle-only button come off or had a set screw. See if the throttle-only button will pop off. If so, there can be a fastener under it. In the other control I had, the throttle handle had...

    Tach non working on Mercury classic 50

    Glad it worked out. Mercury charges a arm+leg for rectifiers. Sierra is better, but they were a $10 part at radio shack, for a much better one. Tach setting is likely 6c or 12P whichever you have.

    Please help 1975 mercury 200 20hp

    Prop is bad. Gearcase is OK to use, except for bent propshaft. It will be a real PIA to replace the propshaft, if you can find one for reasonable cost. Much easier to find a used gearcase and swap 'em. Not sure what you mean by shift lever broker.

    1979 mercury shifts backwards after impeller replacement

    That is a common problem. The cure is to remove the gearcase, turn the shifter CCW until it clicks into neutral, set the control to neutral and reinstall the gearcase.
