    Odd shift cable fail

    Could water be leaking into the cable via the cable bellows?

    1989 Bayliner Trophy OMC 5.8L - Help with new boat

    Ok here’s what can go wrong with the Cobra adjustments: #1, basically can’t change #2, if the cable gets sticky or crud builds up behind the shifter bellcrank you might not get full shift throw. When you set the transom shift cable you first measure cable drag by disconnecting it at both ends &...

    1989 Bayliner Trophy OMC 5.8L - Help with new boat

    This is a 2 cable system & for it to work there are 3 separate adjustments: 1) shift rod adjustment in the lower unit with the drive off 2) also with the drive off, the transom shift cable adjustment; this requires 2 special tools; one to hold the shift bell crank @ 90* to the pivot housing...

    2015 Motor MerCruiser 4.5L 250hp NO EC - OVERHEATING!

    Ok I’d like to see you do the same test with the boat backed into the water. That way no confounding variables like sucking a bit of air which can happen on the water muffs. BTW the only advance warning I got on my engine before I had water in the cyls was when I did a Blackstone oil analysis...

    2015 Motor MerCruiser 4.5L 250hp NO EC - OVERHEATING!

    Also, believe it or not, this Merc 4.5 that you have, really appears to be an adaptation of the old GM 4.3 V6 you see in my pix. Yours has a balance shaft, slightly modified cyl heads and a modern EFI system but the basic design is very very similar. The one down side is that engine parts come...

    2015 Motor MerCruiser 4.5L 250hp NO EC - OVERHEATING!

    Ok let me make sure I'm understanding what you're saying...you get air bubbles from the hoses marked in blue from the cross over to the manifolds when the engine is on, but water flows when you shut it off? Now one thing with this test, is it can be inaccurate if done with the water muffs on...

    1978 Islander 22 I/O

    They are good engines but some of the parts are hard to find. You can also go with a GM 4.3 V6 Vortec which with a 4 bbl carb will give you 225 hp.

    VP 4.3GS Carb Tuning Vacuum Port?

    From the pic it appears that the port side (cyls 1,3,6) are running very rich, could be the idle adjustment or clogged air bleeds on that side. If the carb is not totally cleaned out with proper float adjustment, good needle valve etc it should not continue to foul plugs like that.

    1988 Four winns 180 horizon, were these OMC or Mercruisers

    OMC bought Four Winns & a few other companies around 1986 so many older Four Winns & Chris Crafts have OMC Cobra power. From like 86-96 or so. I would not be concerned about a Cobra to Merc conversion because it’s pretty straightforward no transom work needed.

    New/Returned Manifolds Need Threads Fixed 5.0 GXI

    Those bolts usually get only about 25 ft lbs so that should be ok. Just make sure the sealing surfaces are really flat. That’s the weak spot of this design. The pre cat converter exhaust Volvo used is the wet joint design. Just like what Mercruiser used pre 2002 or so.

    5.0GL fuel small leak near the water fuel separator and possible starter solenoid issue

    There should never be any fuel leaks especially on a gas inboard that’s a real hazard. Starting issue you many need to go thru every connection in the starter circuit to track down the bad connection or source of resistance.

    5.7 Mercruiser Starter problem

    That’s what I’m thinking of. Somewhere it may be losing voltage due to resistance or even something like a bad assist solenoid. When I bought my boat (2002) all the cables were in bad shape. I added a dual battery system in 2005 and up sized the cables to 2 gauge for the shorter ones and 1/0...

    It would be interesting to see how much battery voltage drops during cranking.

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Great work! while you got the engine out, if there is any question about the condition of the power steering actuator, replace it! They are a bear to get at when the engine is in place. I had to remove the rear seats and both exhaust manifolds to do that job.

    2015 Motor MerCruiser 4.5L 250hp NO EC - OVERHEATING!

    Again I'm not familiar with these newer Merc engines and the cooling system is a lot more complex than the older models. However, on the old models the way you would test for leaky head gasket putting combustion gas into the cooling water, was to replace the hoses feeding the exhaust manifolds...

    2015 Motor MerCruiser 4.5L 250hp NO EC - OVERHEATING!

    Ok it’s hard to say but from the pix I’m wondering if the water passages in the exhaust manifolds & elbows are clogged. They don’t look corroded but I’d hook up a garden hose to them & see if they flow well & flow the same each side. Those temps seem really high seeing as how the engine is at...
