    4200 vs 5200

    Here is the info from Atlantic Coastal Welding (Speedy Tanks) where I bought my new tank. Foaming a tank voids their warranty. The neoprene should be cut into 3” pieces and spaced 8” to 10” apart from one another. The neoprene are glued to the tank with the 3M 5200 fast set. I would also wipe...

    Another Motor mount repair question

    Scott and Tod gave me the same advice and they were right. My drill test higher up on the transom looked good but like Tod's picture the bottom of the transom and stringers were gone. I had to gut the interior and put in new stringers and floor including the engine mount area. Mine is a 1976...

    Gelcoat Application Questions

    Well, time to reactivate my thread. As I mentioned on my thread about blocking the boat off the trailer, life happened and I haven't worked on the boat for 18 months or more. Needless to say I have 5 gallons of never been opened poly resin and never been opened sealed gallon cans of gelcoat...

    Boat Blocking

    Well, life happened so its been 18 months or so since my last work on the 76 Sea Ray restoration. The weather is nice so I decided to pull the trailer for repaint (outside) and to refinish the bottom of the boat. Fortunately I have an air conditioned shop and nice flat concrete floor. I used...

    complete Alpha one Gen one retrofit into older boat.

    Be careful with buying harnesses. The pins in the connector are sometimes different sizes and different configuration. So, if you are replacing everything, make sure the engine harness pins match the ignition harness pins in size and configuration. I ran into this in replacing everything on...

    Where to pass the fuel filling hose and vent fuel hose?

    I will measure them this morning and post back. I basically tested sizes to make sure I could pull them through to find the best size. I sized the hole saw to the end diameter of the fittings so they fit tight in the large center stringer.

    Where to pass the fuel filling hose and vent fuel hose?

    Here is a picture of my starboard side piping. The long pipe on the left is for the vent line and fill port ground line. The larger long pipe in the center is for the fuel fill hose. The short one on the right is for the galley water line, water pump wires, and miscellaneous wires that need...

    Where to pass the fuel filling hose and vent fuel hose?

    Yes, I foamed under the floor. No, I wasn't worried about the foam cracking the ABS pipe. I filled through 1 1/2 inch holes so any over expansion could escape anyway. ABS pipe is pretty strong. I have a galley and the water tank is on the port side but the sink is on the starboard side plus...

    Where to pass the fuel filling hose and vent fuel hose?

    On mine, the fuel fill and vent lines ran through plastic "dryer" tube through a hole in the stringer on the starboard side and then forward about 3 feet then up the gunwale. I decided it was easier to use the same routing but I used ABS pipe and ran the hose through that so it can be changed...

    Sounds like you need guide plates on the push rods....

    Potential project boat

    One item I didn't see mentioned is a place to work on the boat over the winter. For doing the work, it has to be bone dry and you must be able to maintain the temperatures up in the higher 70's for best results. Also, keep in mind that gutting a boat means lots of dust (and I do mean lots)...

    Exterior vs interior plywood

    All plywood has voids on the inside as well as on the outside. As Froggy mentioned, marine grade has the external voids filled to finish the surface, however, marine grade also has a spec that limits the allowed internal layer voids. This means you have a much lower chance of a transom...

    Signs of bad pour foam

    I used US Composites almost exclusively for Poly Resin and Pour Foam until the shipping costs got too high to ship from Florida to Washington State. No problems with USC although I had one bucket of Poly Resin that was a little off color. USC assured me that was no problem and it seemed to...

    Exterior vs interior plywood

    I tend to overkill so I used marine grade throughout my gut and build. I was just going to use it on the transom only but decided to go with it for stringers and floor after I got the transom in.... It was spendy though....

    Myacht Roof Issues

    I believe Crowley Marine in Denver does boat repairs. There is also another place in the Denver area that does fiberglass boat repairs (don't remember the name so check the internet). You might be able to get an estimate from one of them to know where you stand.

    Any tips to keeping your boat clean with engine work?

    If you think you might spill a liquid in an area, get some of the large "puppy pads" at a pet store and tape them down with cloth side up to absorb any spills. For example, line the bilge underneath the engine so you catch any oil. Change them out for clean ones when you make a spill.

    Headliner Backer Board?

    The original design on my 76 Sea Ray used a naugahyde material held up with three strips of teak and tucked under the edges where the top mounts to the upper windshield. That was fine originally but the only thing mounted to the hardtop was a couple of handrails. As I plan to mount antennas...

    Camshaft Replacement on Vortec 4.3L 262

    If not available at Summit, try going directly to the Comp Cams website. I actually ordered mine directly from them if I remember correctly.

    Camshaft Replacement on Vortec 4.3L 262

    I may be missing something since I don't have experience with the 4.3L engine but a quick search on Summit Racing lists a Comp Cams Xtreme Marine cam and lifter kit for about $260.00 for a 1999 4.3L engine. Not sure where the $500 to $800 for a cam came from unless that is OEM. Depends upon...

    GM 5.7L TBI & Thunderbolt IV compatibility

    The truck cam may be close but you might want to consider changing out to a marine cam while the engine is out and while you would be changing the intake manifold you have access to the lifters. I went with a Comp Cams Xtreme Marine Cam on my engine which started out as a 96 5.7L vortec truck...
