    PVC for Bunk Skids?

    Was thinking about using thin wall thickness PVC sewer pipe to cover my trailer bunks. Should be easy to saw out a section and use a hot air gun to flaten and bend over the sides of the board and screw in the side of the bunk board. Passed the idea by a buddy and he thinks PVC is too hard and...

    Electric Boat Trailer Winches

    Does anyone use these to winch in their boats? I haven't seen posts on these. I don't like to sink my hubs, but it makes for a long winch in. Luckily my rig came with a Power Winch that I have gotten spoiled in using. However, it is getting long in the tooth. I would make life simpler to...

    Prop Upgrade Pitch Question

    I have a 2009 130 ETEC on my 17.4' by 7' beam trihull. Total weight engine, fuel, persons, gear is about 1700 lbs. I am using the prop from the original 1975 115 HP Johnnie, 13" x 17"p, 3 blade stainless. That engine WOT was about 5200 rpm and 38 mph. This prop on the ETEC pushes 45 mph at...

    Trailer Transom Bunk Supports

    Re: Trailer Transom Bunk Supports The bunks will replace the angled aft rollers and a piece will bridge between the angled bunks to support the flat keel.

    Trailer Transom Bunk Supports

    I'm transitioning from rollers to bunks. The trailer cross beam is a 3 inch tall channel with legs facing toward the front of the trailer. The 12 inch wide transom roller brackets were U-bolted to the cross beam. I am planning on using 4x4's as the transom bunk, one either side of the keel...

    Choosing Diameter

    What is the relation between pitch and Diameter? What is the criteria for selecting diameter? Seems like for a given engine there are ranges of diameters and pitches. Does going up in diameter for a given pitch have the same affect as increasing pitch? Does speed and economy enter the...

    Battery Disconnect Switch Exposure to Saltwater Spray

    I have been looking at these switches on line and cannot find information on their resistance to a saltwater environment. The only convenient place to locate one on my boat is on the side of the splash well above where the motor leads and cables enter the boat interior. However, this is...

    New Engine, What is Included?

    New Engine On Old Boat

    Looks like my '75, 115 Johnnie is near wear out mode, low compression on all cylinders and has developed a carb problem. This is the original engine for my Arrow Glass Cheetah, which I have just finished a restore. I like the boat and the engine, for that matter. The engine has never let me...
