    "Temporary Prop" (Plastic?)

    Is there such a thing, and where would I order one? I've heard they are cheap "emergency" props to get you back to shore. My boat is a 4.3L Mercuiser (1995), so fairly common. To get the exact prop info, I'll have to dig a bit deeper. Thanks

    Radial or Bias Ply Tires for S/A Trailers

    My single axle trailer (towing 20 ft Regal, 1995) has radial tires (ST-205-75R14) and a Bias ply spare. I'm not the original owner, so I don't know how I got this combination...presumably someone bought new radials at some point. Lucky for me, the starboard tire "disintegrated" just as I was...

    "Porposing"-4.3Merc-Alpha 1

    The packaging for aftermarket "fins" says that it will solve "porpoising" (bow lift), and that "fins" provide faster planing to benefit skiers and tubers. My 1995 Regal (4.3Merc, Alpha 1) has those problems. I make sure that I distribute the weight of my passengers to help the cause, but until...

    4.3 LX Merc- Trouble Setting Idle

    1995, 4.3 Mercruiser LX, Serial # OF421280 Idle is 1200 RPM on muffs. Owner's Manual says idle should be 650-700 RPM IN GEAR. On muffs, I have tried to set the idle back using the adjusting screwl. What I noticed is that there seems to be "play" in the linkage. (Throttle cable seems OK, but...

    If the Trim Fails, can you lift the outdrive?

    Novice question. If the power trim system should fail on an Alpha One, can you manually lift the outdrive to get the boat onto a trailer. Helped someone do it on OMC I/B at dock last summer when their battery failed- not sure what outdrive they had. It lifted easily by hand, then we tied it...

    Mercruiser Manuals-What is their code?

    Can someone explain Mercruiser's method of naming manuals. I have a 1995, 4.3LX Alpha-1. Mercruiser seems to call their books Book 16, 17, etc. instead of giving a range of years. Links to manuals would be appreciated as well. Unless I know which "Book Number " to buy, e-bay is not much good. I...
