    Mercruiser 3.0 L Prop Question

    Quicksilver/Mercury Black max is a good choice. Yes quicksilver is a good barnd. They are the same as mercury products but it is a separate line so they can be sold outside the mercury dealer network

    Low RPM at WOT

    Id verify the tach is working corrcectly and was speed by GPS or the dash guage (which are like +/- 8 mph ) ? If you are indeed higgit 45 in that rig I bet your tach is off. I wouldnt buy anything until you verify the numbers

    2 Black sparkplugs

    I think you have a two bbl carb not 4 bbl as no manifold ofr 3.0 exists that takes a 4 bbl carb. If your idle mix is too rich this can cause them to foul like this. I think on a merc 3.0 there is only one opening for the carb so it will feed all cylinders. It sounds like may be you need to set...

    What was mounted here?

    these fittings take the blue plastic drian plugs for winterizing. You can also remove this fitting and just use a 1/4" pipe plug

    Fuel - Pickup, Anti-Siphon, Fuel-Water Separator

    I would think as Kenny mentioned get rid of the in tube screen, get the water out of the tank,change your filters regularly/until it stays with no water, service the points, but you probably also need to clean the carb. Willing to bet there is crud in there

    White Smoke/High Idle

    Hard to say off the info given, may not be an issue - may just be condensation in engine cooking off. is this carbed or fuel injected. If concern is cooling system leak places to check are - 1. pressure test cooling system this will show a head gasket leak 2. possible water is leaking in...

    Volvo Penta runs great but burns oil

    What makes you think the oil needs to be changed? Is it black? You may be getting fuel in there via running overly rich carb wise or if you may have fuel coming in via the fuel pump diagraphragm if ruptured.

    1995 Bayliner Capri 1800LS bimini suggestions

    I went through same exercise on my sea ray 170, had a factory bimini that was part of a multi-piece cover, was low as the front snapped to the top of the windshield. Was nice with the side curtains when it was raining but too small and low for sunny days. I got a unviversal fit bimini from...
