    alpha 1 gen 1 noise

    pull the drive check the gimbal bearing first, as by the mouse I’m thinking that. If that is ok drain drive lube and pull the top cap. See if metal is in the lube or water

    Need help: Bizarre Bravo III freshwater galvanic corrosion quandry

    2012 3.0L TKS runs great with muffs, but slow on lake...

    usually the fuel line is 3/8" double flare like brake lines would think you can get a coupler and a short section of line cut in half & use some 3/8 ID hose to splice in your T for the gauge The TKS uses an enrichment module (valve) to richen the fuel mixture until the engine warms up, it...

    At this point I would test the fuel pressure on the water at the rpm where you feel like you are hitting the wall where it should be doing better. if the float wasnt cracked its probably all right. Mikes carbs had at one time brass floats for mercarbs not sure if TKS is the same thing. the 3...

    1997 Mercruiser 4.3 LX not running steady steady at idle or higher RPM's

    Yes the advance knob should compensate so the light hits on the tdc mark -say you want 8 deg BTDC set the knob to 8 should offset the light to flash on the tdc mark. Also can be used to test total advance which is also important

    I saw new fuel pump but was fuel pump pressure measured under load ? my other hobby is old cars - its a chronic issue with mechanical fuel pumps these days - the pressure output is all over the place, even on what was historically considered good brands

    Carb tuning

    yes some of the factory webber carbs used 3 step metering rods not sure which engines etc but there were a few. Can only think it shows that the binary rich/lean didnt work that well. I found the pump rod linkage slop when I put the AFR meter on. I never would have found it unless I had the...

    I used simple green in an u on my friends holley off his Volvo penta , cleaned it and didn’t strip the finish. Simple green is what edlebrock recommends for its marine finish to not strip the gold Finish off.

    the idle mix screws wont make any difference how it runs at higher rpm , just indicative that something was off if it ran best that many screws out.

    Correct no points or condenser in a delco est. If you are getting a good spark that jumps 1/4" gap or so then no the coil is not the issue Have you checked the tach vs a known shop tach? And you are getting a total advance of say 25-28 at 2500 rpm or so? If that is correct then I might go...

    Help with early 80s mercruiser 140hp

    Id start with a few basics use a spark gap tester to make sure your spark can jump a 1/4” gap or more. If the fuel pump was over flowing quite possible the plugs are fouled. Maybe turn the idle speed screw in / up a bit, fatten the idle mix up a hair. Leave the distributor loose so you can turn...
