    Should I pull heads for inspection, 5.7 liter

    I'd try some Mercury Power Tune to see if that cleans things out. A water mists into the carb while running can also help. Do the leak down test. Once you take the engine apart, much of the diagnostic ability goes away.

    350 MPI Winterize - Block Drain?

    Keep in mind that the flow of water (or antifreeze) through the engine and exhaust is in 'Parallel', so the pink antifreeze will show up in the exhaust before the antifreeze has fully gotten to and through the engine.

    Need Help & Advice on a Purchase....

    Looks like the 4Winns with the V-P engine is your winner. The Mercruiser looks like it has not seen any preventative maintenance in a while. It's all about condition and the 4Winns looks to be the better of the 2.

    Need Help & Advice on a Purchase....

    Got any pictures of the engine bays on each boat to share? I would check both boats for structural rot. Volvo Penta are generally more expensive to fix (parts are crazy money). In 2004 and newer Mercruiser fixed the corrosion issues with added anodes on the ventilation plate and the prop...

    Boat Pricing

    Just checking Bucvalue.com . . . Estimated market value is about $110K + the value of the engines. Total value would be in the $135-140K range.

    Boat Pricing

    The price of new boats going up tends to 'lift' the prices of older boats to some extent. however . . . $160K seems pricey. I see one of the boats (2019 model year) in CT for $169, but then there are a couple in the southern states for around $120K. Engine hours has a bit to do with value...

    1988 Rogue 2420

    Yup . . . My boats have always been moored in a shallow area . . . I was constantly picking up sea weed and it would clog the cooling system. Sea water strainers did the trick.

    Perhaps a sea water strainer would be good. :unsure:

    !/2 ton Truck towing limitations

    Don't tell anybody, but I tow about 14,000 lbs with my 2012 F-150 3.5 Ecoboost. :eek: Of course, I only tow that weight on the back roads . . . I think the top-end rating for my truck model year is 11,200 lbs. I think all of the notes on the ratings charts are to make the lawyers happy.

    Cabrio 350

    Welcome to iBoats . . . Usually it is best to ask these types of questions while considering various boats and before you make an offer. Hopefully some owners will chime in with their specific experiences.

    LiFePO Batteries ???

    Warm spell is upon us in the Northeast USA . . . . Not sure if the LiFePO4 batteries came to life, since I am not there at the boat. If we get another stretch of warm weather, I may have to take a trip to see first hand if & how the batteries come back to life.

    What fuel to run?

    I would not agonize over using 87 from the gas station. It sounds like the engine will be fine.

    LiFePO Batteries ???

    I would say that the engine hatch on my boat weighs at least 500 lbs :oops: . . . maybe more like 700 lbs. :unsure:

    LiFePO Batteries ???

    I'll need to take a look at the wiring diagrams that I have for the boat. There is an extra switch for raising the engine hatch that I have not figured out (yet). Although it may have something to do with using the engine batteries as an alternate power source. (hoping . . . ) Otherwise, I'll...

    Has anyone used the ready lime (not the brand name) to descale their outboard

    I have run a 'descaling' solution through my outboards, as well as the heat exchangers on my I/O engines. Barnacle Buster is a descaling solution, but there are many other brand names of product.

    LiFePO Batteries ???

    Keeping my fingers crossed that I can get the batteries to 'wake up' with some heat into the engine bay. My main problem/concern is that the large (heavy) engine hatch, which is basically the rear seat assembly, runs off of the house battery (LiFePO4) bank. Having that bank shut itself off...

    LiFePO Batteries ???

    @Scott Danforth . . . 16˚F at my house this AM . . . 23˚F at the summer place (boat). Looks like I should try to get some heat into the bilge to wake up the batteries. Winter must be here. :oops:

    LiFePO Batteries ???

    I may have to re-think my winterization routine. . . :unsure: Perhaps have a way to pump some warm air into the engine bay via the blower/intake vents. :unsure: That way, I can force a temperature rise and see if the batteries wake up. I suspect a self heating battery might be better to keep...
