    Massive vibrations...then none

    Tell us what engine/outdrive you have. My first thought is that 1 (or more) cylinders were not firing. So maybe check all of your spark plug wires. While you are at it you could remove the spark plugs for some inspection and to see if you find any water in the cylinders or an issue with...

    4.3 Gl over heat

    Cooling issues seem to be one of the most frequent problems with boat engines, particularly sterndrives (I/O). Since the boat is new-2-you, you should go through the cooling system, which it sounds like you have done some. If the new impeller did not fix the issue, then the overheating may be...

    Showing the Boston Whaler 13 some TLC . . .

    I should have the fuel pump repair kit in the next couple of days. Meanwhile, I've been working on the shifting and throttle levers/linkages at the engine. They were very stiff, making the shifting and throttle control very difficult. I got the shift lever loosened up (it seems like the pivot...

    Maybe my turn for new boat time

    Yes, it is all the 'dumb' stuff that boats have now to make it 'easier' for the novice or casual boater. It makes things more complicated than they really need to be IMO.

    Maybe my turn for new boat time

    I will say, the first year with a new ( or new-2-you) boat seems like a lot of learning, trial & error, and fine tuning. My boat felt like a foreign object last year. This year is much better. I think (hope) you will find the same as time goes on.

    My poor old Buick took a hit

    I assume the white car was not paying attention and drifted right into your car?

    Maybe my turn for new boat time

    I recall you talking about the number of steering wheel turns, lock-to-lock. I think my boat is about 4 turns lock-to-lock. I also have a 'rudder' indicator on my VesselView display, so I can see the steering angle at any moment while docking. It becomes inactive while using the joystick...

    12' Pontoon/Fishing boat nose diving issues!!!!!

    Most pontoons have 2-3 chambers as a safety feature, so a leak cannot flood the entire pontoon. So, it could be a leak in the forward chamber of the pontoon. As @airshot mentioned, we have no visual to go by. The OP & Friend may have to figure it out based on the comments so far.

    2008 Chaparral 275 SSI 8.1 Volvo Penta GXI-J Soft Alarm Issues

    @apisk - I believe you have the issue posted on the THT and Marine Engine forums as well. Have there been any useful comments from those forums that should be considered?

    Got electrocuted when touching cylinder?

    Try touching the cylinder head of a lawn mower or similar engine while it is running . . . same thing . . . a shocking experience (ouch o_O )

    2008 Chaparral 275 SSI 8.1 Volvo Penta GXI-J Soft Alarm Issues

    One of the discoveries from the data was combination of the knock retard going to 5 degrees (which looks like the maximum ?) and the soft warning activating, while the load stayed about the same. This also happened when the TCP and the TPS % values were fairly far apart and the throttle control...

    2008 Chaparral 275 SSI 8.1 Volvo Penta GXI-J Soft Alarm Issues

    Thanks @muc that is helpful to know. It would be interesting to see where the attention should shift towards. I was surprised to see the TPS values at idle. But it could be a Volvo thing vs. Merc.

    2008 Tahoe Q5i 4.3 Mercruiser Engine

    A couple of pointers . . . * 15 years and 70 hours is not a good mix. If the 70 hours are true, then the boat probably sat unused for extensive time periods * Most folks sell nice looking boats for a reason * Everything runs great in the driveway, but it means nothing. I agree that it is...

    MacBook Pro . . . Tragedy

    Yes, I assume that the new laptop will come with the latest. (Ventura ?) My experience in upgrading the OS on older laptops is that you run into performance problems. So, I think this laptop (2017 MB Pro i7, 16 GB) is at its limits.

    12' Pontoon/Fishing boat nose diving issues!!!!!

    3.5 HP vs. 12 foot pontoon . . . Not much HP. Is the bow heavy with fishing gear or other stuff? Do the Pontoons have water in them?

    MacBook Pro . . . Tragedy

    Also a screen shot of the OS & Hardware specifics . . . . . I think that is the latest Big Sur version. There is an update queued up, but it is the new(est) OS (Ventura ?). . . not sure I want to do that. :unsure:

    MacBook Pro . . . Tragedy

    Thx. I have not been able to open the MacBook up, because there seems to be a non-standard size of torx screws hold the base plate, or at least none of the small/tiny size tools that I have.

    MacBook Pro . . . Tragedy

    This morning, I was able to get into the recovery console and run a re-install of Big Sur . . . We shall see how that goes. I'd like to get a more recent back-up of the data before I go over to the new MacBook (should arrive next week). I also noted the the disc structure looks different...
