    Boats from work.

    that's quite scary, looks like the boat must have taken on a lot of water that's why any future boat I own will be full foam filled and outboard powered

    5.7 Cast Iron Intake Manifold - Salt (‘raw’) Water Cooled

    Forgot to add that I use an inspection camera to check for internal leaks in the manifold to elbow gasket. This saves a lot of time if you have no sign of leaks from the outside…

    5.7 Cast Iron Intake Manifold - Salt (‘raw’) Water Cooled

    Same I also do a compression test & oil analysis. If there’s sodium in the oil from salt water cooling you’ll know it that way for sure.

    Puffing steam out vents

    I definitely didn’t have to retorque the ones on my pre Vortec; the gaskets seem to be high quality; I think the bigger thing is that you have to clean out the cylinder head bolt holes in the block (thread chaser) and really clean the threads of the head bolts. Mine were rusty so I would up...

    Volvo penta 5.0gxi 3869255

    I know from checking a crank position sender on another engine (Jeep 4.0 six) there is a way you can check for power and ground at the connector with the engine off but ignition on, and if you have a scanner that can read live data you can see the actual signal that the sensor is sending to the...

    5.7 Cast Iron Intake Manifold - Salt (‘raw’) Water Cooled

    If you're concerned you can always remove the intake and check it more thoroughly by looking at the water ports, often you start to get some pitting there, but if you use a bit of Permatex Aviation in those spots when you install the gasket, it will seal, at least in my experience.

    5.7 Cast Iron Intake Manifold - Salt (‘raw’) Water Cooled

    What I’ve seen around here looking at a number of I/O boats for sale is that very few have closed cooling. Nearly all are raw water cooled yet most seem to have at least a 10-15 year lifespan if not longer as long as the exhaust which deteriorates faster is replaced on time. Ive said many times...

    5.7 Cast Iron Intake Manifold - Salt (‘raw’) Water Cooled

    It's a bit of a gamble but you can poke at the intake right under where the thermostat sits and see if it's getting weak there with a lot of peeling flaking rust. I take a small hammer and a screwdriver and tap at it to see if it sounds solid. And, while you'll get a lot of debate on this topic...

    5.7 Cast Iron Intake Manifold - Salt (‘raw’) Water Cooled

    You have to use the intake that matches your head design; pre Vortec heads require the pre Vortec intake. 12 bolts instead of the 8 bolts on the Vortec and the pre Vortec used the exhaust crossover. They may not be made new but can be easily found used. I found a few good ones for my 4.3 pre...

    5.7 Cast Iron Intake Manifold - Salt (‘raw’) Water Cooled

    If you're referring only to the intake, I have one on my 4.3 which has been on it the whole time I've owned it in salt water in my use since 2002. Not flushed during the season ever, it is a moored boat so full of salt water from May-November every year. Still hasn't rotted through yet. But I do...

    Do I need a trailer?

    I have had the same experience, mine is a 31 year old Load Rite, I checked inside the frame rails and crossmembers with an inspection camera and it looks fine in there. I changed the tongue about 15 years ago and the axle and springs have been replaced with heavier duty parts. Mine goes in the...

    Yep I had very good luck with the Cobra. I’ve also got a spare drive that I’m going to get rebuilt; the original which was last resealed in 2006 is still shifting fine…

    Puffing steam out vents

    PS that boat looks like new for a 1984 Freshwater must be a treat Nothing lasts like that here in the salt pond My boatyard guys are amazed I'm still running an '88 Cobra, that has sat in salt water every summer since I bought it 23 years ago. The only parts needing replacement due to salt use...

    Do I need a trailer?

    CE Smith sells a nice put-it-together yourself galvanized trailer for small boats, if I wanted one for my 10' Walker Bay that's what I'd buy, because the only thing that lasts here is galvanized....

    https://www.marineengine.com/newparts/part_details.php?pnum=OMC0985060 this is the kit I used, it is for all the Cobra trim cylinders, in the early years of the Volvo SX they used the same exact trim cyl and then they changed the body of the cyl so that the rear fitting doesn't have the trim...

    Just rebuilt the trim cylinders, now the outdrive won't stay up under load

    Ok watched the vid out of curiosity, the kit used has a different seal than what was used on the OEM and is different than the BRP kit I used on the Cobra (OEM), there is one big red seal taking the place of 1 oring and 2 plastic spacers. Not sure if that makes a difference here or not. But, you...
