    Two Layers of 3/4 CSM versus One Layer of 1.5 CSM

    Thanks. I was planning one layer of 1708, one layer of 1.5 ounce CSM, and Gelcoat. Eventually I want to get snap in carpet for the high traffic areas. This was before I discovered my mistake with the 3/4 ounce. So, sounds like I can use up the 3/4. I try to use wet on wet as much as...

    Two Layers of 3/4 CSM versus One Layer of 1.5 CSM

    Is there any issue with using two layers of 3/4 instead of 1.5 CSM on the floor? I just realized that I had bought a couple of rolls of 3/4 by accident and its not returnable. Will it cost more in resin or will two 3/4 come out about the same as one 1.5?

    Cushion and Seat Rebuild

    The design of the boat means the seat cushions at the stern and in the V Berth will need to be structural. I will try again to find a star board supplier in my area so I can get a physical sample to play with, otherwise I will likely go with marine plywood and a coating as mentioned. Thanks..

    Cushion and Seat Rebuild

    The old cushions use just cheap exterior plywood. I haven't found a source close by for starboard. How do you attach upholstery to starboard? It doesn't look like it would accept staples.

    Cushion and Seat Rebuild

    I plan to use either marine plywood or exterior plywood for the backer wood. Before covering the wood with either foam and fabric (inside the V Berth) or foam and Marine Vinyl (exposed to weather), is it better to leave the wood bare, cover it with a polyurethane paint or cover it with a layer...

    Blowby through vent tube? Mercruiser 3.7

    Check the bore diameter. Did the block get over-bored, cylinder walls too thin and broke through? Piston slap caused a ring to gouge in? If over-bored too far, I wouldn't sleeve it. With that kind of a failure I would be looking for a replacement block.

    Window question.

    Sorry to take so long answering. My inner ring has little nubs on it and just snaps into the outer ring. So, it is designed to pop in and out. The outer ring with the "glass" is attached to the hull with screws.

    want to run my engine out of the boat.

    Do you have a picture of it and a diagram of how it is wired into the engine? The condenser or "filter" would normally be inside a points distributor. Sometimes they are mounted to the side of the coil and attached to the coil post. Condensers only have one wire and use the case for ground...

    Water in oil

    Start with a compression check on all cylinders. Vortec heads are prone to cracks if not handled properly but, as Lectro88 points out, more likely a head or intake gasket. Did you get the head and intake bolts torqued correctly? Did you use new head bolts or the original ones? By the way...

    Blowby through vent tube? Mercruiser 3.7

    You need to be at the shop when they pull it apart to see for yourself what was going on. With all of them oil fouled, my guess is they put the rings in wrong (didn't offset the ring gaps, maybe a compression ring in upside down). Any shop can make a mistake and you want them to own up to a...

    Blowby through vent tube? Mercruiser 3.7

    Rings might not have been installed properly, that is, the ring gaps should be offset from each other and some of the rings have a top and bottom. Its good that you used breakin oil but did you do a run-in sequence on an engine stand or on the boat for the first 15 to 20 minutes to seat the...

    Window question.

    I removed the ones on my 76 SeaRay and they had silicone RTV underneath as sealant. I don't know if your boat is the same but that is what I found was holding mine in. My inner trim ring came out easily, it was the outside that was stuck. It could be that yours has sealant that was over...

    want to run my engine out of the boat.

    If it was running before, you might want to figure out why it isn't running now and get that fixed first. As mentioned above, clean all connections, look for a broken wire, check switches are making proper contact, relays and starter are working, etc.. Then, if you decide to clean up the...

    want to run my engine out of the boat.

    If you go with heatshrink and/or crimp lugs get the kind that have adhesive sealant on the inside of the shrink and the terminal insulator to seal up the connections. Helps prevent corrosion in the long term.

    5.7L Non-Vortec to Vortec conversion

    Couple of notes on Vortec heads. Make sure they are checked for cracks. If you go to higher lifts and stronger valve springs, make sure you change the press in rocker studs to the threaded studs. Most shops will pull the pressed studs, bore and thread the heads for reasonable price when they...

    want to run my engine out of the boat.

    If you buy used, you will find that over the years there have been 8, 9, 10 and 14 pin wire harnesses depending upon the year and engine. The 14 pin being the newest and is typically used with the newer fuel injected engines. Although they look similar, some harnesses are made for outboards...

    Birch for V Berth Framing

    Thanks. Will look into those. This wood actually won't see any water as it sits just below the V Berth cushions. Water up that high and the boat is sunk...

    Birch for V Berth Framing

    I need to frame in what amounts to small storage locker space underneath the V Berth cushions. The old frame uses 1 x 2 (.75 x 1.5) as part of the framing. I don't know what type of wood it was. I am considering birch to replace the old solid wood framing as it is the best I can find in the...

    Correct installation of thermostat?

    Pictures? Looks like I misunderstood about the sleeve. Thought you were talking about the TStat.
