    Mechanical Fuel Pump Arm Movement

    Granted the last manual fuel pump I installed was my old 73 Ford pickup but I am wondering about the travel in the fuel pump arm. In the old days the pump arm moved back and forth a good half to one inch. My new Carter marine fuel pump for this 5.7L only moves maybe a quarter to 3/8 inch, is...

    Such a Thing As Making the Hull Too Rigid?

    I am going from the factory work of somewhat randomly squirting in bedding for stringers with what appears to be a power caulking gun (if they had them in 76) then missing the bedding material so that almost all of the stringers were floating in foam with no fiberglass except on exterior...

    Tube/Pipe for Routing Fuel Fill Line and Vent

    Under my floor and foamed in place were two tubes like dryer vent line so that wires and the main fuel fill line can connect to the belly tank and the water tank (overnighter). Both of them were badly deteriorated so I need to replace them before I cover and floatation foam. One is 2 1/4 inch...

    Near Miss with Cutoff Wheel - Hull Cut

    Working in the boat today and knocked over a couple of tools. Somehow my cutoff wheel turned on when it flipped over on its side and put a cut in the hull. Fortunately I grabbed it quick and it didn't go all the way through but I don't know how close it came. It is on the curve from the inner...

    Floor Joint Design?

    I am almost to the point where the floor will go on the new stringers. I have a question on the point at which a floor joint is required (8ft plywood in a 22ft boat) at right angles to the stringers. I am thinking that I should bevel the edges between the two pieces at 45 degrees with...

    Upper Housing Cap Paint Question

    Do the mating surfaces of the upper housing and the upper housing cap normally get painted to prevent corrosion or are they sealed enough when assembled to keep water out? I know there is an O Ring that keeps water out of the inside of the drive housing but since I am repainting the whole...

    Screw and Pilot Hole Sizes

    In the past when I was young and dumb, I broke a few stainless screws trying to put them into fiberglass on the sailboat that I had at that time. Later I found out that the screws will bind in the fiberglass without the right size pilot hole. Is there a table of screw size versus pilot hole...

    Drive Housing Pit Filler?

    So, just got back my upper housing, bell housing, gimbal ring and gimbal housing back from media blast. My lower housing a a new Mercruiser so painting not needed and my transom plate was in great shape without any corrosion so doesn't need paint either. To paint the blasted parts, I will be...

    Test Splash?

    Does it make any sense to do a test splash with new stringers in place and before floatation foam and floor is installed to check for leaks? Outdrive installed but without the engine installed. Test splash would be just drop it off the trailer, let it sit for 15 minutes or so and put it right...

    Glassing Stringers - First Time

    Does anybody have an end picture showing the profile on how much radius to put on top edges of the stringers before laying 1708 over the top?

    Shore Power Recommendation

    I am setting up dual batteries (start and house) using the Blue Seas ACR. I am clear on how that hookup is done but wondering about the best shore power charger model (including galvanic protection) and how to properly connect it to the ACR circuits. I expect to occasionally spend the night on...

    Stringer Cleat Board Question

    My new aft stringers are set in place with peanut butter under the full length of each. Corner joints are tabbed in so ready to start tabbing and glassing the stringers. So, here is the issue. My old stringers have cleat boards running the full length of the stringer for attaching the floor...

    Floatation Foam in Closed Space

    The factory originally left all the stringers pretty much floating on the inside. They relied upon the foam to just flow under all the stringers and fill all the spaces. That allowed the floor to bow up under the pressure from the foam. I am bedding all of the new ones. In the motor mount...

    Stringer and Bulkhead Questions

    I got my engine bay stringers bedded and started tabbing them but ran out of resin. So, while waiting for more, I decided to start on the forward stringers. The outboard stringer on the port side fell out while I was removing the foam floatation because it was rotted and the out board...

    Filling holes with Polyester Structural Putty

    I have quite a number of small screw and rivet holes to fill. They run up to about 1/4 to 5/16 inches in diameter. Structural putty is quick and easy to prep so will it work fine for filling holes like these instead of mixing up peanut butter? Can you use it to fill the overdrill hole size...

    Roof Top Equip Mounting Question

    I am laying out my roof top equipment and wondering about through bolts or screws. The boat originally had a hailing speaker mounted to the front windshield frame and horns down on the deck at the bow. I decided to clean that up and move them to the roof top so that I don't have lines fouling...

    Water Pump Question - Alpha 1 w/Closed Cooling

    I saw a note in another thread that mentioned something about the Alpha 1 Gen 1 water pump does not provide enough flow for use with a closed cooling system. I have a brand new closed cooling system setup and brand new dry joint manifolds for my 5.7L Vortec. Is it true that the Alpha 1 pump...

    Stringer to Transom Joint Question

    Do you run the stringer right up against the transom wood, fillet and tab that or do you need to put peanut butter between the stringer and transom wood to bed it? Also, is it better or easier to lay a bead of peanut butter and then set the stringer into that or put in small foam spacers then...

    Bonding Polyester to Epoxy - Will this Work

    So, originally I planned to use epoxy for all my stringer work but the budget doesn't allow that. I got to thinking about using epoxy to just bed the stringers in peanut butter and then polyester to glass them in. My question is this, if I glass in the stringers while the epoxy peanut butter...

    Bonding Wood Backing to Fiberglass Shell

    I am ready to start putting new wood into my hardtop. This is for support and to strengthen the fiberglass in some areas. It provides screw and bolt points holding windows and trim in place. The fiberglass shell is from 1/8 inch thick to about 1/4 inch max where the wood goes in as a backing...
