    1993 Volvo penta 431 no power from alternator to fuel pump

    Hi. I had the almost identical engine to this years ago. The aq205. The 431 came just after and only for a couple of years or so. On my dash, there were fuses for the ignition that are worth checking. Yours may be under the dash. Mine were in it. Glass fuse type.

    1993 Volvo penta 431 no power from alternator to fuel pump

    Identical to the AQ205 4.3 V6 AD. Just with a fuel pump signalled off the oil pressure switch.

    Adding 100+hp. Would you re-prop ?

    Haha. Sorry AD…no offence intended there. I take it back !

    Adding 100+hp. Would you re-prop ?

    I’d say the hull you put an engine in, is just as or more important perhaps. I don’t think your hull will have the ability to push through a certain barrier perhaps

    Adding 100+hp. Would you re-prop ?

    No probs. Was just curious there. About the 454…I’d think you’re better off being small block. No nothing like as much as some of the guys that have replied already, but as far as I’m aware, the small block option would be better for getting power. The old 454 in my experience over the years on...

    Adding 100+hp. Would you re-prop ?

    Wondering what engine would have been put in this new, to have the hull rated to 415hp, in 97. Anyway. I’d say you’re doing almost impossibly well to see near 50 mph now with that engine. I know of a 300hp mpi with b3 and 26” props in a stepped hull about that size, that’s getting 5000 rpm and...

    What do i need to get my engine data on my Garmin Echomap?

    No probs. You’ll be fine then. Thought it might be the case.

    Wiring Harness Dislodged 2018 Mercury 115 hp

    That’s a pretty poor looking install, I’d say. Mine is really securely fitted and binded/wrapped. 2016 115 CT

    What do i need to get my engine data on my Garmin Echomap?

    Probably being picky here. But if it’s actually an efi…none of the above will work…but presume it’s a typo and it’s an mpi..with it being a 2008 ?

    What do i need to get my engine data on my Garmin Echomap?

    It won’t. It’s blue tooth. Will show you GPs speed and a map though. Not a chart. All other engine data and fuel is displayed though

    Mercury Trim Switch Blowing Fuse (unusual circumstance)

    Yup. Me too. I do this when reversing off the trailer at a certain slipway I use about once a year. Take it back 🤦‍♂️

    Drive lube dropping?

    I’d say it’s normal to have to top up the bottle after a full drain of the gear oil. Always a air gap between the top vent where oil is filled to…and the res tank in engine bay. Naturally oil runs down and fills the void.

    Mercury Trim Switch Blowing Fuse (unusual circumstance)

    Not to give you a hard time or anything…but in 40 years of owning and working professional on boats and using them at least every weekend in summer, I don’t think I can think of a single occasion that I’ve used the trim in reverse. But all that aside…there was a recall on the merc 115 engines...

    Mercury smartcraft sc1000 sea water temp issue

    Thanks Dingbat. It was the mercury one that came with the engine package. Normally doesn’t bother me. Such things, but flicking through the menus for engine data…then seeing that the temperature of Loch Lomond (a glacial formed body of water that peaks around 11 degrees C at its warmest 😂)...

    outdrive gear case flushing?

    Wouldn’t think you’d need to, unless there were signs of any contamination. Years ago I had water in a 290. I flushed it out with diesel.

    What do i need to get my engine data on my Garmin Echomap?

    Yeah. As above. Not cheap to do it I’m afraid.

    インペラー取りはずし方教えて (Tell me how to remove the impeller)

    You’ll need to pull the pump out the back of the boat. Get an impeller removal tool or stick the whole thing in a big vice. Big spanner with a pipe extension on it. You’ll need a new wear ring too. I presume you mean it’s a mercury 120hp

    How to Switch to Antifreeze Cooled Engine

    Difference between the two 4.3 gm in carb and mpi format, when they were available at the same time as an engine option. Both the same rpm. Carb is 5 gallons per hour and mpi is 4.5 Interestingly they both have the same rpm range. Also I’d add that the mpi at 4800 rpm uses a little more fuel...
