    Running warm after overheat event

    2014 V8-380-CD. Closed cooling. My marina gets to less than 2’ of water at low tide. When docking yesterday, I had my first overheat event after expecting it to happen someday after all these years of docking in shallow muddy water. Alarm sounded while at idle speed and I immediately saw the...

    Fuel pump “over spraying?”

    Been battling a bad misfire issue on my 2014 V8-380-C-D. Rich codes on both banks, you can see the short term trim pull fuel on both banks as soon as the O2 sensors come online. Oil getting lots of fuel contamination. Raw fuel on spark plugs. Threw in the towel and decided to let a local VP...

    SPN 4236 FMI 1 troubleshoot

    2014 VP V8-380-C-D engine. A sporadic issue I’ve had over the last couple seasons is now happening pretty regularly. Slight misfires felt and the engine light and audible alarm will sound, engine then goes into limp mode. Cutting power gets me out of limp mode.Code I get via my Easyconnect app...

    DPS pressure and vac testing

    Drained the oil on my 2014 DPS-B drive at end of last season and was bummed to see oil the color of Bailey’s. Approx 400hrs on it. With oil drained, I hooked up my pressure tester, and it held 15psi for 10 minutes. I didn’t have a vac tester, so I plan to do that test this month. Soapy water...

    Garmin 720S maps question

    Don't do any fishing but would like a single SD card that can show me depth charts for Upper Chesapeake and Lake George NY. Boat came with Worldmaps installed which don't seem to have any resolution. Bluechart? LakeVu? Anyone know which to buy?

    2014 380hp 8.1 GiC, is time@rpm logged in ECU?

    According to surveyor of boat I am looking at, scanning ECU will not yield time@rpm data. Is that correct? You can get that data from Mercruiser ECUs.

    Duoprop first service questions

    Looking at a 2014 Chaparral with 8.1 GiC engine and Duoprop drive, 100hrs. Seller says drive is ready for its first service. I don't own VP manuals, I'm a Merc guy, so what does "first service" entail on a late model Duoprop? Approx cost? Thanks.

    Bottom Paint Removal: what am I getting into?

    Looking at a very low hour fiberglass hull boat with Interlux Micron applied 4 years ago. I don't do any boating that requires bottom paint. In fact, some places I trailer to prohibit TBT bottom paint (which this is not), which suggests that I could get flagged at an inspection station by a...

    8.1 GiC 400hp

    Looking at a 2012 boat with this engine. Seems pretty rare. Big blocks either are 375 or 420/430hp HO rated from Volvo and Merc. Why did Merc never have a 400hp version of this big block? Even their 8.2 standard output is 375? Just trying to understand how oddball this engine is. Are...

    Interlux Micron bottom paint removal

    Anyone use this stuff to remove Interlux Micron bottom paint? Recommended by Interlux: Interstrip Semi-Paste Looking at a like-new fiberglass hull boat, very low hours, stored inside, with Micron bottom paint applied about 4 years ago. I'm not a fan of bottom paint, as I only boat in fresh...

    Hard starting, 350MAG MPI

    07 Chaparral 254 Sunesta. My random hard start continues, even after replacing the IAC with a brand new OE unit. In fact, it may be a tad worse. I have to crank the starter a few seconds to get the engine to fully fire. If I release the key early, on the next turn the engine will crank and...

    Broken bolt gimbal housing, engine side...

    Replacing the water pipe on my 350 MAG, I was able to finally get to the junction on the engine side of the gimbal housing. Being as careful as possible, I still managed to break one of the studs holding the plastic outlet to the housing. I have about a quarter inch still sticking out but I have...

    Water pipe replacement challenges

    While I had my drive off to refinish some corrosion spots, I decided to overhaul the wear items at the transom. 8 year old boat with no previous service history, so it seemed like the prudent thing to do. I watched every video I could find out there on the procedures, and read the repair manual...

    Safe to run drive fully trimmed up?

    Low tide on the Chesapeake can get very skinny, and even with GPS I have been caught out a couple times. How trimmed up on the drive is safe at fast idle speed to move the boat out of a jam? Is fully trimmed up a no-no for the u-joints at that speed? If so, then what trim is safe at that...

    Tarp Techniques

    Not only are my snap on mooring covers not 100% effective in keeping rainwater out of my interior, I've also grown tired of spending an hour first washing the pollen and tree crap off everytime I want to go boating. I bought a 20x30ft tarp to cover the boat when on the trailer in my side yard...

    Water in the transom...

    Previous owner dry stacked my boat and someone installed the GPS transducer inline with the stern strap path on the starboard side. I decided to move the transducer, which required drilling new holes. When drilling, I noticed the material coming out on the bit was damp. Uh oh. No water came...

    Risers and seawater impeller, 350 MAG MPI

    Previous owners used the boat exclusively in salt water, 83 hrs logged. To be safe, I pulled a riser to get a state-of-the-union assessment. To my surprise, and possibly untrained eye, the side I pulled looks almost new. Yes? Any reason to pull the other side when this one looks so...

    3M 5200 shelf life?

    Instructions on tube says that once opened, it must be used within 48 hrs. What happens beyond 48 hrs? Something so horrible it must not be mentioned? Seriously, if it has not begun to harden, is it still safe to use, or is some unseen chemical transformation happening that makes it bad to...
