    I am getting ready to replace my boat's transom. I have done this before with another boat but I can't remember if there are any adjustments on mounting the inner plate. My MC manual is not clear on the inner plate. It has plenty information describing how to install the outer plate, transom...

    Repairing Mercruiser Y Pipe?

    Welding aluminum is a pain. It has to be thoroughly cleaned. It is not forgiving. I rebuilt a Y pipe years ago but I cannot remember what acid or solvent I used to git into all the nooks and crainies as the result of corrosion. My Y pipe is corroded externally and will be easy to access with...

    Bravo 1 Trim Switches Installation?

    I am installing new limit and sender switches. However, I am not real clear if I should add or coat the two mated halves that are molded onto the wires before pulling the wires through the transom assembly. It seems to me that these should be coated with something in order to seal against water...

    What is the correct tap to use for 1/4" x 28 tapered grease fittings? Should I use a NPT tap or straight wall? I must install several grease fitting in a Bravo OD. Fellow boater instructed how to drill and tap but didn't explain if tap was tapered or not.

    Installing hinge pin grease fittings on Bravo 1

    Neither of my Bravo's have grease fittings for gimbal rings where hinge pins are located. My previous Alphas all had them. I can not really tell if these are sealed or not. I have never seen sealed "anything" on a salt water boat. But, these may be special. Regardless, I have to pull ODs for...

    Restoring Garmin 2006C waypoints from data card

    Garmin manual implies that you can back up and restore waypoints to a data card. 2 cards came with 2006c when I purchased boat. Top card is "Bluechart." Bottom card is labeled "GMZ502L." I don't have a clue what "GMZ502L" does, other than perhaps it is a data card to backup waypoints. Has anyone...

    Refill Ritchie Compass

    I have a large Ritchie compass that definitely needs fluid added. I suspect it was originally filled with mineral oil, but I am not sure when it was manufactured. West Marine wants to sell me 20 bucks worth of Isophril L, when a couple of bucks worth of mineral oil (which I already have) will do...
