    Alpha 1 Water Leak into Boat, from Exhaust Ports? (videos)

    Ah. Do you have a mercathode system fitted. That looks like it might be where the cables for that go through the transom assembly.

    Alpha 1 Water Leak into Boat, from Exhaust Ports? (videos)

    Hard to see properly…is it not your shift cable bellow

    First time winterizing 4.3 mercruiser, alpha one.

    Literally can’t believe there is even an argument or case being given to warrant such a method. I think a line needs to be drawn and made clear the correct way to go about this. Nowhere in a manual, will you find anything suggesting anything like or close to this method. Should I have any...

    Partially damaged spark plug hole on 115 optimax

    Above advice is the way to go… On a side note…is she definitely a 115 and a v6 ? Not sure I’ve been aware of such an engine…but I’ve been corrected plenty of times on here before !

    water in cabin bilge

    I’m a little unclear on specifics around what set up you actually have. Is the pump in the place you mention, definitely the shower pump ? Not just a forward bilge pump ? Is there drain channels that normally allow draining aft, that are blocked up ? Back to the shower pump set up. Is there a...

    Blown head gasket / overheat

    Hi. Not normally one for commenting on these engines. Never had one or even anything close to it. But thought I’d ask..does she show specifically that it’s an overheat alarm or are we assuming that the beeping means an overheat ? I may have missed it mentioned, but what kind of boat is it on ...

    MerCruiser model 496 MAG (H.O.) 425 HP loss of power

    Was it the high pressure fuel pump that was changed out ? I’d watch the voltage indication when this occurs too..see if anything is happening there. When you say it won’t go past 1500 rpm. Is it dead on 1500 and as if it’s being electronically limited at that..or more like lack of fuel and bogging

    Bravo 3 loud knocking/ticking Sound Video

    What kind of boat is this ? Don’t suppose it’s a formula with the silent thunder system. With baffles and water box in the back of it ?

    Volvo Penta 2.3L AQ131 runs better with timing advanced

    Is your belt a tooth out ? Do those engines not often tend to suffer cylinder head issues ? You think there is any chance you may be compensating for an issue, by means of timing advance ?

    Mystery motor

    Hi. It’s an old Tohatsu 18hp. That eagle was their logo from decades ago.

    I really should have paid more attention!

    Mercury 150 not performing well under load and drinking gas.

    Think the rainbows will just be 2 stroke. I think you really need to clean the carbs properly, to be honest. Spraying them rarely does the full job. Been fooled in thinking it does, far too many times before now. Learned to just do them properly and save the wonder or bother of taking them off...

    Bravo 3 loud knocking/ticking Sound Video

    Does it do it when in gear at idle ?
  14. Q

    Mercury 150 not performing well under load and drinking gas.

    Were the carbs properly cleaned ? And properly set up ? How’s the fuel delivery ? The vent on tank or remote tank ok ? Other than all that…the complaint about the fuel consumption…I had a wee chuckle over that. Even when these things are running perfectly, they love a drink. I’ve a 150 on a...

    Engine dies going into reverse

    I should be doing the bellows soon too really. Played it lucky too long.

    Engine dies going into reverse

    I’m excited…only 4 years to go. I’ll need to go easy on her until then. Think I’ve been pushing my luck with that and other few things…but no sign of wear just yet. Original gimble and UJ too. 700 odd hours and 20 years coming up !

    Battery discharge. ...normal?

    I’d also add, that my stereo and diesel heating digital controller is left live when boat isn’t in use…can be left for weeks and no problems. If your battery is good…got to be something drawing from it that’s substantial. I know that modern cars can sometimes have issues with parasitic drain...

    Mercury 150 Four Stroke charging

    Hi. Did you jump start it with a running engine on the other end of the leads ? Doesn’t often end well perhaps. I have a similar aged 115 merc. The output charge it has is very low when at idle and first started. Takes a wee while to give a charge out. Then it can actually regulate to provide a...

    Stern light

    Hi…apologies for pointing out the obvious…but I am aware of some boats having a 2 stage rocker switch for lighting. Sometimes the set up can mean that the stern light (which can double as an anchor light) is not activated at one of the positions perhaps. Or something like that. Other than...
