    Smartcraft Master Reset.

    OK, It took forever to correct this issue but I finally got things working.. In order for the Smartcraft gauges to offer the option of what motor to gets its data from, the gauges have to SEE both motors (STBD and PORT). On my boat, it seems that the original rigging was incorrect. By installing...

    yamaha motor tilt/trim failure

    There is a manual pressure release valve that will allow the motor to be moved up or down but moving it up can be difficult depending on the motor size. The valve is a flat screw fitting hidden inside of the motor bracket usually on the port side of the motor. Watch out for fingers and other...

    Optimax coils

    You can measure the resistance of the coil and compare each to the others. It is easier to use a spark tester with the coils installed and the motor cranked over (or run). No spark or weak spark should be obvious. If you have suspected coil issues, it may help to take a look at the coils and...

    Mercury optimax

    2006 Optimax 150 2 stroke

    Fuel pressure by itself is not a sufficient test. You need to also measure air pressure in the injection system. It is important that the air pressure be 10 psi higher than the fuel pressure. So if air is 90, fuel rail pressure should be 80. If there isn't a 10 pound difference and you do have...

    Oil alarm sounding periodically

    The tank on the engine should normally be full. It should not get to a half full level. Two things will account for that: The tank on the motor doesn't know it is low on oil or the remote tank is not feeding oil fast enough to keep the engine tank full. If you get the alarm, pull the cowling...

    Mercury 150 xl 2 stroke, carbureted, head temperatures vary by 15 to 25 degrees

    Was the overheat test and measurement done on the hard or in the water? If on the hard were muffs used? Did you see a decent pee stream? Does the motor overheat at idle or only when run at higher revs and/or speeds? If it runs hot at idle do the temps come back to normal when the revs are...

    07 Optimax PCM sounding continually

    He is pretty backed up when I spoke with him a few weeks ago. He said he was going to stop taking in work while he catches up on the backlog
