    Thoughts on New Gen Direct Injected VP 5.3L v8 350HP?

    Also: DI is being pushed because it's more "efficient" what it also does, is dirty up intake valves then the engine doesn't run right so you get to have to have them cleaned something I never ever had to do with port injection, or a carb. What solution has been tried by some automakers? Add port...

    Thoughts on New Gen Direct Injected VP 5.3L v8 350HP?

    With any of these modern high tech engines you really need a good & skilled dealer because without diagnostic tools & training they are very tough to fix yourself. One reason why I still have my old boat with a points distributor and a 4bbl Quadrajet

    Awfull time launch & retrieve roller trailer

    I don’t use mine a lot because my boat is moored in the salt water but where I am a bunk trailer definitely would not work. Shallow ramps and 6 foot tidal swings. It took me a while but I finally got my roller trailer the way I want it. I was able to lower the boat about 3” to about 1.5” above...

    Michael’s done a ton of stuff including a transom rebuild. Quite a talented & skilled guy!

    The Vortec intake gaskets are kinda delicate too. I actually prefer the pre Vortec. Those never had intake gaskets leaking coolant into the cam valley like on many GM cars the first few years of production till they changed the gaskets and publicized the change in the torque specs

    Great work, it is good for those who have not done this before to see what's involved. The pump given it's age looks very clean inside....

    new to me 97 ski sanger dlx 20 stringer movement near stern

    On my boat before we fixed the deck 17 years ago, the rotted gas tank mounts let go coming off a wave returning from Huntington Bay and let the tank move with a BANG! that and putting my foot thru the deck when winterizing it that fall made a partial rebuild necessary, lol. Made the new mounts &...

    Post up some pix of what you have might be easier to assess it then.

    Also: On the Gen + true Vortec keep in mind that the intake manifold bolts take much lower torque than the pre Vortec, IIRC pre Vortec is like 30-35 ft lbs whereas the Vortec is like 15 ft lbs. I think there was a mistake in the Mercruiser shop manual when the Gen + first came out that used the...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    On mine I get a slight squeal when coming to the stops but no grating sounds, and as old as it is, I never had problems with the drive drifting down after being trimmed up. So maybe you're on the right track. Why not look on the EU Volvo Penta parts site and see if they sell a rebuild kit for...

    4.3 LX water in the oil...

    Even before you get to that point... get a thread chaser (not a tap) and clean out all the cyl head bolt threads in the block and make sure that the new bolts will fully thread all the way in. Your engine is closed cooled so they will probably be pretty clean but on a raw water cooled engine...

    Ah yep thought it had the Merc Batwings based on the year range but someone already up dated it. Then you did say you had full closed cooling. Your heads & block look good but I guess the machine shop will tell the tale. The block deck you’ll be able to judge when you get all the gasket...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    The pump I don’t know about, I’d search around here on the VP I/O forum, to see if people have had SX pumps apart & fixed them. I’m guessing the one you have is similar or the same as the one Volvo used on the SX series rather than the original OMC Cobra design. I have been able to get parts...

    Sea Ray 1977 200SR

    Try looking on Barr Marines website to see if they make a version of that manifold. If you REALLY love that boat and want to keep it fix what’s needed to get it going but if it’s a constant headache think about doing a transom rebuild and swap in a modern (Mercruiser) drivetrain. Big job but...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    If you do it your self there’s 2 things to get past: 1) end caps, these can be tough to get off, I used heat time & patience 2) removing the eyelet end that’s on the piston rod, this has to be done to replace 2 of the seals in the cap. Micheal Romer covers both in his vid I advise leaving the...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Looked at it, might be the same thing with a different part #. There are basically 3 seals for the end cap and 1 oring and 2 split rings for the piston.

    Did this engine have those one piece batwing manifolds on them? I know you said the passed the acetone test but I wonder if they leaked when they got hot? Those manifolds were known to be troublesome, I think they were used from 96-99. There is a Merc conversion kit to change it to the normal 2...
