    What should I do with this free boat?

    Hi. In my experience…something like this is is all dependent on the health of the engine. If she has compression, it’s worth (certainly to a boat guy) getting her back in working order. But be advised…I even if that engine runs and has health…if the gearbox is missing, you’ll be out of pocket by...

    Oily exhaust water

    Oh. Yeah. That’s a fair old bit of oil right enough. But could also be from oil sitting in the exhaust for a long time, perhaps. That looks more like the signs of age old oil build up sitting in the exhaust that’s came dislodged.

    4.3GL-D Issue

    How hot is the alternator getting ? I’d think normal windings would run at around 70 degrees c or so. Rough idea would be if you can touch it for more than a few seconds..it’s less than 70 degrees c.

    Oily exhaust water

    Absolutely normal to see oil residue exit the exhaust. Simply because as an absolute principle of operation…a 2 stroke is what’s know as a total loss lubrication system. There will always be a sign of oil out the exhaust. Especially noticeable when running in your driveway on a trailer. Wouldn’t...

    New boater with trouble starting engine

    Have a look at that fuel filter and if that has a water sensor on it too.

    volvo penta AQ 280 dp pt

    So weird Scott. Must be a Europe thing then. Every 80’s drive similar to this had the same pump I had, that I’m aware of. Loch Lomond is full of them currently. Could point out half a dozen in the boats just in my yard for sure. Unless I’m getting mixed up with which is which. The oildyne has a...

    Mercruiser 3.7 (470) wont turn all the way

    I’ve backed it up plenty times previously. Have a read back. Would take me an age to write out again.

    volvo penta AQ 280 dp pt

    That would be for slightly newer models. Mine was an 89’. Definitely original to the boat when new. No separate reservoir tank. All one unit. I’m aware there are a few drives that fly under the “290” flag. DPA dpb etc etc. But generally mine was a 290dp from 1989 with an AQ205 4.3. A friend had...

    Mercruiser 3.7 (470) wont turn all the way

    There is maintaining and there is maintaining a 3.7. I get it. Some guys like to persist with them and spend more time tinkering on the trailer than actually using it. But most guys just want to turn the key and rely on their boat…with just the usual maintenance

    New boater with trouble starting engine

    Ok. If you’re sure it’s a 4 stroke…it could be a number of things perhaps. Like temperature, low oil or a host of other things. It may also have a fuel water separating pre filter with an alarm to indicate the detection of water in the lower bowl. My 2016 merc certainly does. I’d have a check or...

    New boater with trouble starting engine

    I’d hazard a guess that’s a low 2 stroke oil alarm, if she is a 2 stroke.

    volvo penta AQ 280 dp pt

    No doubt. Had the same issue with an 89 290 dp. Was the wee ball seals on the old prestolite pump to blame.

    A mercruiser 4.3l MPI with a low weak idle hard to start

    Assuming your gauge is off. You’re missing the main cause of this on the mpi. The famous diz cap !

    volvo penta AQ 280 dp pt

    Hi. Just making sure it’s definitely the problem you think it is. These are famous for the actual trim pump valves passing and being the issue. Causes the drive to not hold position and creep down, but not lose oil externally ? Thought I’d ask.

    Mercruiser 3.7 (470) wont turn all the way

    From the last time I did a compression on the thing my friend had issues on…when it was in good health, it had fairly high compression compared to your result. Don’t quote me on it…but I think they were all about 160/170 psi when it was running ok. I think you must have a valve related issue. Or...

    Motor opinion

    But I’d say we are talking specifically perhaps. Also I’d admit, you’ll be right about other engines too though !

    Mercruiser 5.0 MPI 2013. Crank but no start.

    What does this mean ? Is there something plugged into the distributor ? Any I’ve seen don’t have anything plugged into the socket on the diz. Mine defo doesn’t

    Marine oil VS Standard Synthetics

    Tend to agree partly with this. I don’t think I’d go fully synthetic on an engine that’s essentially been around for decades and decades…doing just fine on mineral or semi all the while. These aren’t high tolerance state of the art and finely built things. Amazing as they are..solid as they...

    Marine oil VS Standard Synthetics

    You could use the quicksilver synthetic blend 25w40 that mercruiser use in the identical in every way, engine. The 4.3 mpi gm. Not sure where you are in the world, but here in the U.K…there isn’t (in my opinion) a better marine oil than the rock oil stuff. That’s either 10w40 or 15w40 spec for...

    Does mercruisier 2.5 have the function of overheat alarm?

    I’d doubt you have one. Be sure of it even. But nothing to stop you fitting one.
