    Oil Pan Gasket Question - 1996 Chev 5.7L vortec

    I am assembling my engine and ran into a question on the correct pan gaskets. This is the one piece gasket and one piece rear main seal engine. The description of the oil pan gasket for marine says it is heavy duty and thicker than the standard truck gasket. Not sure why it would be thicker but...

    Preventing Transom Replacement Clamp Bolts from Sticking?

    I am getting ready to install new plywood in my transom, have dry fit it, and made clamping 2x4's. The question I have is how to keep the clamp bolts from getting permanently stuck in the fiberglass that will ooze into the bolts during clamping? I have heard use cooking oil on them but then...

    Alternator, Power Steering, Brackets 1996 5.7L

    So, I am building a 1996 5.7L vortec engine. Mercruiser (via Crowley Parts Lists) shows a V Belt system in 1996 and I want to use a Serpentine belt system. Mercruiser shows a Serpentine system on the 1997 5.7L. I am assuming that I will need to use brackets and idler pulley(s?) from the 1997...

    Sea water pump question

    Is the sea water pump (mounted to the side of the engine) only used for the closed cooling systems or is it like an option on the standard cooling system? Just trying to decide if I need one since the closed systems are so expensive I will just run a standard cooling system. Thanks....

    V Belts versus Serpentine Chev 5.7L vortec ?

    I am building from the ground up so have a choice between traditional belts or serpentine belt. My thought was that if a component goes bad while on the water, it might be better to be able to isolate it by removing the belt and limp home. However, I would prefer a serpentine belt. Any pro's...

    Windage Tray 1996 5.7L Short or Long

    I am starting the assembly of my 5.7L vortec engine (4 bolt main) but ran across a question on the correct windage tray. I ordered and received an Engine Quest tray with standoff bolts. It has 5 standoff bolts so is intended to bolt at mains 2, 3 and 4 (2 at main 2, 2 at main 3 and 1 at main...

    1996 5.7L Vortec Timing Cover Question

    I want to go to the Cloyes 9-3145 double roller timing chain and gears on this rebuild. The engine is a 1996 5.7L vortec with roller cam and block is an 880 block. I know the standard timing cover won't fit a double roller. This will be a Rochester Quadrajet setup with Thunderbolt IV ignition so...

    Mercruiser Flywheel Housing and Coupler 1996 GM 5.7L

    Does anyone know the correct Mercruiser part numbers for the flywheel housing and coupler for a 1996 GM 5.7L with Alpha One drive? What I have in my hand for parts is a 96119 housing and a triangle coupler but don't know if those are correct. I have seen the 96119, 865657A04, 12675A7, and...

    5.7L Vortec Part Recommendations

    I have a heavy duty (4 bolt main) 5.7L Chev Vortec block (late 90's). I am looking for recommendations on parts to buy to build it up. It has a stock crank, cam and pistons as near as I can tell. I think this was a truck engine due to the 4 bolt main. I know all the arguments for and against...

I am thinking of using two relay powered circuits: 1) one for engine, nav lights, panel lights, docking and transom lights, wiper and VHF and, 2) one for cabin lights, courtesy lights, stereo, water pump, etc.. I am planning a fair mount of...

    Reference Points for Dimensions

    As I am replacing the transom, stringers and floor, I want to make sure and get everything true and aligned. I may be over thinking this but how does everyone determine a reference point for all measurements. For example, do you run a straight edge across the gunwales and measure down to...

    Trim Tabs - Restoration

    The boat I am restoring had hydraulic trim tabs (vintage late 70's early 80's). I am not sure if the pump was/is working since I bought this boat at auction. There appeared to be a little bit of leakage at the starboard trim tab cylinder but the pump had oil in it. I can bench test the pump...

    Epoxy Brands, Types, and Applications

    I read the sticky on Fiberglass resins and that was very helpful but I am wondering about the various types and their applications. I have 4 different needs and wondering if one epoxy will do all or should I use different epoxy types for each type of job. Looking for recommendations for the...

    Tools - Fiberglass and Wood

    I read through the safety sticky and it talks about safety equipment which is great. I was wondering if some of you could expand upon that with some recommendations and brands and models. For example, paint and resin requires respirators capable of handling VOC's but many of those you can buy...

    Stringer Design Question

    This is what I found when I opened up the floor to replace the transom. I cut the floor back about 8 inches away from the transom and cutout the floor and stringers. Here are the port and starboard cross sections of the floor and stringers. In the picture labeled stringers port A, I annotated...

    Fuel Tank - Paint or Powder Coat

    Not sure if this should be here or in engine section but here goes. I pulled the 60 gallon tank from my 76 SeaRay and although it looks in pretty good shape, I do see electrolysis started in a few areas. It has had old gas and sludge in it for many, many years. I bought this boat at auction so...

    Finally got the boat moved to my shop in Washington state and getting a chance to move forward on restoration. I started the restoration work on the transom.

    76 Sea Ray 351W to Chev 5.7L Repower Stringer Changes?

    I need to rebuild the transom and at least part of the stringers. 76 Sea Ray SRV 220 OV Hardtop. It had a 351 Windsor OMC. When I do the stringer work, do I need to change the design to put in a 5.7L Chev Vortec or will it fit in the same stringer/engine well configuration as the current...
