    Manifold/riser kit

    The Barr Marine aftermarket conversion kit is $1200 plus labor. A new engine by the time you’re done if you’re paying someone else will be about $5000. Those were a bad design they couldn’t get consistent wall thickness so there were a lot of failures (water intrusion). My OMC also had the one...

    some useful information on 5200, 6,000 and 7,000 lb axles (bearing/hub differences)

    The other tricky aspect of these axles is that some axles take a 2.25" ID seal and some take a 2.125" ID seal, have to check that before installing. The axle Champion made for me takes the 2.25" ID seal

    Don S Winterization link not working

    I have 2 Cobra transom assemblies one is on the boat the other is a spare and both have all 3 drains. I’m wondering if it’s an early model (1986) maybe the drains were added later. The drains on the starboard side are there (top is the vent bottom is the actual drain) in case water gets into the...

    Second Happiest Day . . .

    Great! I told my brother to buy a shop manual for his 2020 Mercruiser 4.5 if he wants me to winterize it.

    Bleeding trailer surge brake fluid - single handed

    I just did mine today. Used the same one man bleeder kit (Lisle), works well, my brake fluid came out looking just like what went in. The last time I changed the backing plates was about 6 years ago so I got pretty good life from them. Installed a 6,000 lb axle & 12" drum brakes to replace the...

    Another winterization question

    The AF above is for environments that reach -100. The -100 (burst rating) stuff is liquid to -55 or so normal antifreeze used as an engine coolant mixed 50/50 usually won't start to freeze till -34*. so the -100 is more than adequate anywhere in the lower 48 and most of Canada

    Why does the 4.3 not rev higher if it's oversquare?

    That was the solution GM came up with for the shaky Buick 231V6 with the 90* angle between the cyl banks in about 1975/6 when they bought back the tooling from AMC. They used it for a few years sold it to AMC who used it in the CJs then bought it back after the 1st oil embargo. So when Chevrolet...

    That’s burst temp not freeze temp. If there was no need they wouldn’t make it.

    -100 burst rated AF is liquid down to about -55. And there is a -200 as well…

    Why does the 4.3 not rev higher if it's oversquare?

    It’s a pushrod OHV Chevrolet whose basic design dates back to 1955 with the 265 cu in V8. They were not designed to be high rpm engines; with a few exceptions like the 302 and 350 cu in Z28 versions.

    Water when pulling stern drive

    did the grease come out looking rusty? If so I'd replace for sure and replace the gimble bearing as a matter of course. years back I had one bellow leak and at the time my mechanic (I wasn't doing all the I/O maintenance yet) really greased them up and they are still fine all these years...

    Bellows full of grease/oil

    yep I'd figure on at least changing the gimble bearing, if this was fresh water you may be able to pump out the milky grease from your u joints, if you see rusty grease coming out of them though they should be replaced. You do not want a u joint failure on an I/O that can cause catastrophic...

    some useful information on 5200, 6,000 and 7,000 lb axles (bearing/hub differences)

    http://blog.easternmarine.com/bearings-for-5-2-6-7k-axles/ I recently upgraded the 3500 lb axle on my old single axle Load Rite to a 6000 lb axle built for me by Champion Trailers (as was the previous axle). I always wondered what the differences were between 5200 lb and 6000 lb axles was since...

    1994 OMC 5.0 EFI no start

    I might (carefully) unplug the computer connectors and fuel pump relays and dry everything out with a hairdryer (low heat). I re-animated my old iPhone 6 that got too damp this summer that way and it still works!

    As I said in an earlier post it’s like trailer leaf springs. If you don’t spray regularly with corrosion x or similar they will rust bad in a few seasons here in the salt. If you spray 2x a year they will look good even after 10 seasons. So you flush your engine at the end of the season manually...

    Fuel Problem

    I think that’s what my mechanics were taking about, warpage causing a vacuum leak
