    VP 5.7 GL caruburetor swap to 4 barrel?

    Glad it worked out for you. On a GM marine V6 or V8 I’d always want a 4bbl carb. Years back my family owned a 72 Chevy Impala 350 with a Rochester 2bbl and a 75 Olds Delta 88 with a 350 with a 4bbl Quadrajet. The Olds was a lot more responsive from the midrange to the top end. I’m running a...

    Dry Launch

    http://tecniqinc.com/trailer/ I put a set of these on about 5 years ago and have not had to touch them since. Excellent! This is 100% salt water...just make sure you have good grounds.... I hooked up my ammeter to them for fun and with the running lights on they only draw 1/2 amp! With the old...

    Air Don't Freeze Winterization

    Once you have the heat exchanger you can either simply drain or run AF through it.

    Air Don't Freeze Winterization

    It’s worth it to me because: Know the engine isn’t rusting away over every season You get an unexpected cold snap and can’t get to the boat at least the engine won’t be ruined Engine runs at a better temp as GM intended Most of all when you get older you can keep boating don’t have to give it...

    Cut Holes for Improving Engine Access

    agreed there are ways to make these panels easily removable, that or install a remote oil filter mount. I used long screws with wing nuts, and cut the big heavy bulkhead in half and hinged it with a take apart hinge. Much easier and don't have to drill holes in the wood deck.

    Air Don't Freeze Winterization

    That’s the only way to go for us costal boaters. Spend the money up front 1x for the closed cooling and remote oil filter and put an end to the foolishness of pulling out seats crawling around in the bilge pulling drain plugs. Get a winterizing tank and add a live well pump or bilge pump to...

    '84 Lund 3.0L IO engine runs, locks up, runs, locks up

    There is usually a tag riveted to the lower unit with the drive ratio and serial # on the Cobra.

    Air Don't Freeze Winterization

    Well, I never pushed my manifold life to the max for obvious reasons, but when I had the heads off 4 years ago I really inspected that water passage in the original intake manifold and it looked really good, not much flaking rust, I had bought a spare from ebay (fresh water parts sellers) but I...

    '84 Lund 3.0L IO engine runs, locks up, runs, locks up

    well you got a Cobra for sure. When you took the top cover off were the gears covered in oil, or not? It looks like the engine is from an older OMC boat because of the color, but it may not really matter.

    Second Happiest Day . . .

    I actually called them today to ask about something else and also asked about their inventory and the guy I spoke to said they were 'loaded with trailers'....I think his name was Chris....

    Air Don't Freeze Winterization

    but fresh water boaters hardly ever if at all replace exhaust manifolds while we in the salt pond change em every 5-7 years. think of trailer leaf springs some people do nothing, they rust like mad in no time and most of the time they are out of the water other people spray them 2x a season...

    Second Happiest Day . . .

    https://riverheadtrailer.co/ https://greatoakmarina.com/ these are a couple of local trailer dealers on Long Island, not sure if they have inventory though. I was thinking of getting a new trailer for my old boat and decided to just put a heavier duty axle under it instead.

    New to winterizing..is it possible to fill cylinders with antifreeze?

    While you found the 4 plugs and drained those, you also have to remove the bottom end of the large hose that connects the circulating pump to the thermostat housing, that pump holds a lot of water and it won't drain unless you disconnect that hose. The 5th plug they are referring to is on the...

    Twin 5.0 alphas,2 power steering pumps?

    I'm still running my orginal P/S pump but picked up a spare reman unit off of ebay for about $150. Hope you don't have to change the steering actuator. Not a fun job. I just did mine last month, lasted 33 years so I can't complain. This is the older Bendix style one used by Merc and OMC till...

    4.3 MPI Exaust flapper

    Correct, most likely won't hear it in the water. You can localize the noise with a mechanic's stethescope to be on the safe side. I had one making noise out of the water running on the water hose and it drove me crazy till I found it. As it turned out I did a top end overhaul (new heads) and...

    4.3 GXI-F (2005) No spark or power at the coil. How do I check?

    great work and follow up! many years ago, I changed the points and condensor on the family car (1972 Chevy) and it would not start. Lucky I kept the old points. New ones were defective! Always check your work and back track to the last thing you changed, or touched lol.

    '84 Lund 3.0L IO engine runs, locks up, runs, locks up

    I found this confusing to follow. First you said it’s a 3.0 Volvo. Then next it’s an OMC Cobra. So which is it? If the Cobra and no oil over the upper gears you will need a rebuilt upper gear housing at the least. Those units take approx 2 qts of gear oil and have to be filled correctly. If you...
