    Trim and tilt problems on 5.0L

    Are you referring to the grease fitting on the side of the transom mount? That’s to grease the gimble bearing. The only way to grease the ujoints is to pull the drive which should be done every season for inspection.

    Running 5.7 without choke on quadrajet?

    Was your auto choke not opening? Here I would keep the choke for reliable starts in cooler weather but yes you can run a Q jet with no choke. These old style divorced chokes seldom need anything more than a good cleaning of the choke valve and shaft and choke linkage. After many years you MAY...

    Unusual oil consumption? VP GM V8 Vortec 5.7

    I'm thinking that some of the variance in these is because of difference in the pressure relief valve & spring in addition to the gauges not being 100% accurate. Perusing some owners forums of S-10 trucks that all used the 4.3 which is very similar to the 5.7 they report 60 at speed, 40 at...

    Unusual oil consumption? VP GM V8 Vortec 5.7

    Mine has always run that pressure (approx 60 psi) with the boat up on plane, 3200-3600 rpm let’s say. Never had a problem!

    95 Mercruiser 4.3 water in oil

    Other uses of balance shafts included the Mitsubishi 2.6 inline 4, the Chrysler 2.5 inline 4 and the Porsche 944 inline 4. All of them were large 4 cyl engines that tend to vibrate & shake more than smaller displacement 4 cyl inline engines. PS For 6 cylinders an inline 6 is very smooth compared...

    '95 OMC 5.0L fuel line

    Well that’s a problem that believe it or not I have not had yet even though mine is a good bit older. I would post it up in the VP section because those models are really the same as Volvos. Might be seals in the trim rams or the pump. Any leaks from the trim rams?

    I’ve been there many times & camped out with NASCAR fans as well. Lotsa fun!

    95 Mercruiser 4.3 water in oil

    I see a bit of rust on the throttle blades and the underside of the casting. Water in the fuel too? Might be the smoking gun In any case I'd put the intake back on, spray fogging oil in the cyls, crank it over carefully and do a compression test. You might get lucky as it is only fresh water...

    Unusual oil consumption? VP GM V8 Vortec 5.7

    He said it doesn't. Too bad that would have been an easy fix! Normally on small block Chevrolets even with an old engine with tons of hrs on the short block like mine they will be at least at 20 psi at slow idle (600 rpm) with a hot engine even after coming off plane. Over 800 rpm I am back up...

    95 Mercruiser 4.3 water in oil

    What GM did was an inexpensive way of creating a 90* V6 using existing V8 tooling. This was done due to the energy shortage in the '70s because all they had was the Buick V6 built a few years earlier and the old GM inline 250 cu in six. They did it with the Buick V6 creating the 231 cu in V6...

    95 Mercruiser 4.3 water in oil

    What's interesting in your pix is that the water passages in the cyl heads have LESS rust than the intake ports, and your intake ports are a lot more rusted than my old ones were. So I'm still suspicious that it came in through the carb.

    95 Mercruiser 4.3 water in oil

    This is what mine looked like when the water got in from the HGs, after cleaning most of it up, notice the cyl head intake ports don't have rust in them, not like those in the pic above (remember salt water engine here). If you look close you can still see some of hte milky oil

    95 Mercruiser 4.3 water in oil

    On mine when the HGs blew the cam valley, valve covers had milky oil everywhere but no rust in the intake passages as seen there. I did get the water out & changed oil 3/4 times within a week though. Salt water doesn’t forgive!

    Dog house is a style of engine cover some boats have with small jump seats on either side of the engine. Instead of the big Sun pad….

    95 Mercruiser 4.3 water in oil

    When you pulled the plugs do you poke em with a pick or similar to make sure rust flakes aren’t clogging the drains? Any suspicious rust stains on the manifolds or block suggesting freeze damage?

    95 Mercruiser 4.3 water in oil

    Agreed that pic does not look like what you have when water gets into the oil from failed head gaskets or even intake gaskets. Was there corrosion inside the carb?

    Unusual oil consumption? VP GM V8 Vortec 5.7

    Agreed if oil is burning you’d think you’d see it on the center electrodes of the spark plugs. So it’s starts out OK with 4 bar oil pressure (~~58 psi which is fine) but then the oil pressure drops and you find that the engine is very low on oil. I would do a compression & leakdown test even...

    1995 Four Winns Horizon 190 Trailer wheel bearings

    I added brakes to mine years ago (3500 lb axle, 10” brakes) and last year upgraded to a 6000 lb axle with 12” brakes. It stops so well you don’t even feel it back there. We have steep hills here so no brakes is not an option.

    95 Mercruiser 4.3 water in oil

    It is run off the camshaft. GM found that even after adding an even fire (split journal) crankshaft to the naturally unbalanced 90* V6 there were still vibrations so the balance shaft removed the rest of those. I think they were added in ‘95. Vortec heads came in ‘96. My old ‘88 doesn’t have it...
