    How can I troubleshoot the wrong trailer light

    Turn signals are powered via separate relay outputs. The only way this can happen is the left turn and tail light wires are switched or the left turn signal is somehow shorted to ground, back feeding the power to the tail light circuit. With the connector unplugged from the vehicle, there...

    96 Evinrude 50 cutting out

    That advise is worth exactly what you paid for it....;) Guessing the vast majority of the "disablers" do so because they don't want to spend the money to properly maintain the oiling system. Cheaper to replace a $400 pump with a $50 pump and dump oil in the tank

    spin-on gas filter

    Not a fan of in-line rock and stick catchers. They are redundant and something else to go wrong. Got to ask, where are you going to mount this thing? I would be more concerned about ripping the mounting bracket off the "wall" than damaging a sight glass

    . . . and I Thought Hi-tech Boat Engines Were Bad . . .

    When weird stuff is happening in control systems the first place to look is the grounding system. Most new cars run an auto-sense circuit to shut down power to non-essential accessories if it senses problems in the charging circuit or a current drain. Others like my truck, are capable of...

    spin-on gas filter

    The sight bowls are heavy duty. You would damage the metal filter shell before you damaged the sight bowl. But, I could see concerns with damaging the 2-turn drain screw assembly if the unit was mounted in a location with a high probability of being damaged. In that case, I would simply go...

    does black stain on vernatherm mean head gasket leak?

    Guessing you're calling the thermostat a vernatherm? When exposed to certain substances like acids, alkalis, or salts, the copper will react and form compounds that are dark in color. Similarly, if a copper is exposed to high temperatures for extended periods of time the surface may become...

    Think water entered gas tank ?

    Had a similar situation a few years back. Long story, turned out to be a combination of excess rain, a recessed vent cap and bad luck. Known problem with fuel fill. OEM sent me updated part for free. No problems since What clear canister? You do not reuse coalescing fuel filters. You...

    Dual motors for a 17' super sport LTD

    Unless you have dual fuel tanks I'd stick with a single motor. Lower cost, lighter, less drag, less maintenance, less problems.

    Copper crush washers ok to use?

    Seems people are confusing hygroscopic (absorbent) and permeable (allows fluids to pass through) Nylon is hygroscopic but not permeable. Nylon is saturated ~10% which causes the material to expand roughly 3 to 3.5%. In other words, a 0.090" thick nylon washer will grow in thickness by roughly...

    Copper crush washers ok to use?

    The OE washers for my Evinrude 200 Ocean Pro are nylon flat washers. The washers deform when tightened so a new wash is required every time they are removed

    Aluminum Hull Grounding Question

    In reality, the motor and the power distribution circuits should be completely isolated from the hull. If you have continuity between either your in for problems down the road
