    Hello all, I want to install a remote oil filter mount for my 4.3 V6, is it neccessary to replace the filter mount bypass valve?

    Just a follow up on this topic I found out the block adaptor in the kit I got from Michigan Motorz was made by Canton Racing in Ct. So I called their tech line and asked the question of whether change the bypass valve. They said I could change the bypass valve to the 30 psi unit, or use their...

    Volvo Penta 7.4 overheats

    I think you might have a little colony of slimy creatures inside your water intakes! Since I pulled out that plastic screen I've been able to clean out the water intakes just using the tool I made up without having to split the drive like I did some years back. Not sure if the holes on the Volvo...

    Volvo Penta 7.4 overheats

    Is this boat docked in salt water for the season? If so you can have marine growth inside the water intake area, and it will restrict the inward flow of cooling water to the impeller. In this case you'll have to split the upper and lowe drive housings and inspect that area and any other...

    Hard starting 4.3LX, normal or not?

    We had one just like this, 1975 Olds Delta 88 with a 5.7 Olds V8 and the Turbohydramatic 400 trans. It had the 4bbl Quadrajet just like my boat but had the hot air heated choke which sucked air through a passage in the intake manifold heated by the exhaust cross over. Worked great, in temps down...

    Hard starting 4.3LX, normal or not?

    I would start it up with the flame arrestor off and observe the operation of the choke. Cold engine it should close all the way, or at least almost close all the way. Right after it starts, a vacuum operated valve will pull the choke open a fraction so the carb gets enough air to keep running...

    Hard starting 4.3LX, normal or not?

    Once you've owned a Chevrolet and an Olds with Rochester carbs and that same divorced choke and live in a cold winter climate (like I did in the '70s) you learn how to make those chokes work. The problem with using a divorced choke in marine applications is that the engine runs cooler and takes...

    Good Tow Vehicle ? - Tow Rating ?

    I am a fan of previous gens of GM land yachts as well as those from FoMoCo. If I could find a nice 94-95 Chevy Impala SS I'd buy one in a heart beat. I am not so much a fan of modern vehicles, after you own one for a while the designed in nanny devices start to drive you crazy and I hate...

    Can I replace my 1994 Mercruiser 5.0 2BBL (305) with a 1998 5.7 2BBL (350) ?

    Agreed if I were doing an engine replacement on a boat with a 5.0 Chevrolet I'd for sure go with a 5.7, it is the exact same physical size and weight but has much more power potential, also make sure to go with a 4bbl intake and carb, don't cheap out with a little 2 bbl carb. For carbs, you can...

    Hard starting 4.3LX, normal or not?

    Yep this is the way electric fuel pumps work on old school engines that originally had mechanical fuel pumps. Powered off the starter till the engine fires then as soon as oil pressure builds it is powered through the oil pressure switch. Make sure all the electrical connections for the fuel...

    4.3 vortec engine ( water in oil )

    The block casting #s are on the bell housing area behind the cyl head; look on both sides. There are also casting # s for the cyl heads that you can see if you remove the valve covers.

    Water leak at the transom

    It depends on the boat and the installation, some have been able to do it, you may need a crowfoot wrench or an offset box ratching wrench, to reach them.

    Also, don't trust your dash gauge 100% and assume that the alternator is fully charging the battery, check it with a digital voltmeter, you will find under or overcharging that way.

    StarCraft holiday 18ft 3.0 to 4.3 swap, good idea?

    The 4.3 is perfect for smaller boats as long as you have room for the engine mount on each side of the engine. There are a few members on here who swapped from a 4 cyl to a 4.3 (Rick Stephens, Nola Mike?) so you should be able to search and see how they did it. The engine is shorter but a lot...

    Water leak at the transom

    Here’s what I’d do. If the boat is out of the water run them on the water hose and watch that spot carefully. If you get water there it’s likely that the rubber oring seal between the exhaust Y pipe & the transom mount. That might rule out the bellows & transom seal. If not & it only leaks...

    Water leak at the transom

    I'm in a salt water area and have moored my boat for 20 years here and they would never look that good. So once you go this problem squared away you'll be good for a long time. Four Winns builds a nice boat. Here's my old '88 on the mooring.
