    MacBook Pro . . . Tragedy

    I should . . . Well . . . all by itself it restarted and seemed to be stable enough to run. It appears that the 'CleanMyMacX' software, which is supposed to make it run better, caused the thing to crash. I will see if it keeps running, and try to get a back-up of the data. I think I got to...

    MacBook Pro . . . Tragedy

    My MacBook laptop of 6 years decided to go into a reboot loop all of a sudden today. I tried a bunch of things, but the situation only got worse. I first was able to boot into safe mode and it would stay running for about a minute then crash . . . blank (black) screen no error message . . ...

    Looking for a 35 to 38 foot boat that I can trailer

    Most state regs are 102" (8'6") width. I just measured my trailer width . . . about 107" . . The bunks are 68" apart. . The trailer overall length is 37 feet. . . This trailer could probably hold a 35 foot boat, at the most. Probably a 35-38' boat would need even larger Maybe 40 feet...

    Showing the Boston Whaler 13 some TLC . . .

    The Whaler's time on the water this season was short-lived. Looked to be an ignition problem, and on closer look the wire harness was a crumbling mess in some places. . . I ordered a new wire harness and got it all hooked up . . . . . . . After figuring out there was no fuse provided in the...

    Is Vessel View worth it?

    The 521-20 is a fault/warning message that the engine got too hot. It does not mean that the sensor is bad though . . . If you want to get full diagnostic info, find faulty sensors, etc., then VesselView will probably get you only part way there. For same/similar money you could get the Rinda...

    Looking for a 35 to 38 foot boat that I can trailer

    Here are a few ideas . . . Formula 382 - total head-turner :p Fountain 38 Express . The Formula might be an 8'6" beam, but not a cruiser . The Fountain is wider and has more cabin accommodation. Here is more the cabin cruiser . . . SeaRay 380 . As for lowering 'bridge' or more probably...

    Looking for a 35 to 38 foot boat that I can trailer

    What you are thinking may not exist. Tell us a bit more about your boating experience and experience with towing a large boat. I tow a 33 foot boat . . . about 11 feet wide. . . needs special permits.

    Also, found this, which is about the same symptoms as you are seeing . . . Not sure it is any help though . . . https://www.justanswer.com/boat/7ucr4-2010-8-1-gxi-j-engine-started-getting-alarm.html

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

    One thing that I did see was that the Voltage Ref#2 follows the TCP Command slightly. The voltage rises slightly as the 'Command' value goes up and lowers slightly as the 'Command' value goes down. Is there a single connector or a few connectors for the throttle control? I am wondering if...

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

    Another thought that I had was. . . . something going wrong in the throttle control itself. Is there a full wiring diagram for the engine? The one you posted was for the controller itself and somewhat generic. Also, keep in mind that this effort (so far) is only to get the 2 voltage sources...

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

    Not sure. You should use a parts diagram to locate it. I'm reaching the extent of my V-P knowledge, sorry to say (I'm more of a Mercruiser guy, and they use a different approach to the throttle control) . . . Maybe the member @muc might be able to offer some suggestions.

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

    I was thinking the TPS may be the issue, it starts of higher than it should and ends up lower than it should

    What happens to the reference voltage if you remove the TPS ? Not sure you did that . . .

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

    Here is another combo . . . When the TPC are over 50% and the difference between the TCP and the TPS values are 15% or more, the soft warning occurs. 2 examples . . . . . . I am wondering if the TCP and TPS values should be close if not nearly identical, and when they are not and at a...

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

    Also, a 14% TPS at idle speed seems way too high. It should be more like 0-5% . Perhaps the issue is the TPS and not the TCP. :unsure: Sorry for the multiple messages . . . I am multi-tasking with this thread and my Evinrude 25 HP, which I've been working on much of the day. 🤪

    It looks like TCP only activates when the throttle control is put in gear. .

    I'll go back and look at the data to see if anything else comes to mind.

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

    I am thinking . . . What is the difference between TPS ( Thottle Position Sensor) and TCP (Throttle Control Position) ??? I'm thinking the TCP is drive by wire, where there is no throttle cable. There must be something else in the overall circuitry that is shorted out and the TCP...

    Is Vessel View worth it?

    I have VesselView 4 on my 2016 Mercruisers. It does not show fault codes, only warnings, which are not very helpful. The only value that I have found with vessel view is that it puts the more important engine and outdrive information in one screen, rather than looking at a variety of discrete...
