    Wheel Bearing Inspection Interval

    Probably less than 5 lol! I live 1/4 mile from the water & the boat yard.

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    Well on mine, I had blown HGs putting water in 2 cyls not enough to hydrolock but when I took the heads off it was obvious. The engine would start, run rough, then after about 5 min smooth out. When it cooled off they would get sticky again. You can also get rust on the stem, that for sure will...

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    PPS I went back and looked at the beginning of this long thread and your exhaust elbows looked HORRIBLE, (way past replacement time) it seems quite likely that you had water leaking into your cyls, causing sticky valves, if the heads have not been off, do a leak down test and see what it shows...

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    PS one hydraulic lifter being adjusted too tight can cause a valve not to close all the way and that can cause low compression. Heads were checked by a machine shop? It is common due to leaky inboard wet exhaust that you can have sticky valves causing lower compression.

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    If one is at 80 psi that’s too low. A small block Chevy in good shape should have compression #s of approx 150; but it you did the comp test on a cold engine it would not be that accurate. Warm up engine set throttle wide open, remove spark plugs & disable ignition. After I replaced the cyl...

    Wheel Bearing Inspection Interval

    I had the same experience. 17 years with the first axle and 2 years with the second. When the drum brakes need service I change the seals & inspect the bearings. If I were dunking every week that would be different but this is a moored boat & the trailer only goes in salt water 2-4 times a year.

    4.3L OMC Cobra 1988 engine knock/rattle

    Exactly if you pull the drive & it’s quiet it could be a REALLY rusted gimble bearing or someone might have refilled the Cobra drive the wrong way and trashed the upper gear housing. Hopefully it’s the former not the latter

    1991 Sea Ray Bowrider 170 - Trying to remove bench seats and put in captains chairs. Is this possible?

    When I did my old '88 FW H-200 about 18 years ago....the square panels are the reinforcement for the pedestal seat mounts. Mine came with the pedestal seats so I just duplicated what was there.

    Bottom up restoration! MY FIRST BOAT

    Do you have a clear registration or title to the boat? Wouldn't want to do all that work, and then not be able to register it.

    Converting to Electric over Hydraulic this week

    Interested to see your impressions of the difference between standard surge brakes and EOH

    1993 Mercruiser 7.4 - Is my Problem Carb or Thunderbolt IV module

    If you have to use E-10 gas there are better quality accelerator pumps available from Cliff's High Performance, make sure you tell the shop the carb is for a boat.

    Roller trailer OK for aluminum boat?

    I’m think they use them in Australia but probably with more & smaller rollers than are used on US trailers

    Replacing 95 merc 4.3 with 87 OMC 4.3

    When I bought new Barr Marine manifolds and elbows to replace the one piece OMC V6 units, after I removed the paint they were perfect, couldn't even get a .001" feeler blade in under the straight edge anywhere. Here's what a new manifold looks like... one more tip, if re-using the old...

    Replacing 95 merc 4.3 with 87 OMC 4.3

    .003" feeler gauge I meant. Yesterday the forum was acting wacky lol. Volvo Penta published a document indicating how to check the sealing surfaces and how to re-surface properly.

    Replacing 95 merc 4.3 with 87 OMC 4.3

    They might be fine; the “official” way to check these is to lay a straight edge over them and see if you can fit a .003” in anywhere it should not fit, if they are really good a .001” won’t fit.

    1993 Mercruiser 7.4 - Is my Problem Carb or Thunderbolt IV module

    I wouldn’t exchange an original marine Q-jet for anything you get via internet because you might wind up with a Franken carb that will never work right. I used to think a QJet was too hard for a novice to rebuild but when I took a crack at my original one I found that it’s no harder than any...

    Replacing 95 merc 4.3 with 87 OMC 4.3

    On second thought I might want to go over those elbows with a file or belt sander and then check em

    5.7 TBI possible fuel pump issue

    How about the crank sensor? These can cause trouble when the engine gets hot.

    1993 Mercruiser 7.4 - Is my Problem Carb or Thunderbolt IV module

    Did the mechanic actually test the timing advance with an advance timing light at different rpm? Between an electronic ignition system & a carb, a carb is more likely to cause running problems.
