    4.3 volvo penta flywheel problems

    I'm wondering if could it be that the studs were not tight in the threads in the flywheel even though the nuts were tight to the coupler. Might have to double nut the studs to get them tight enough. OMC used this exact same way of attaching the flywheel to the crankshaft and the coupler to the...

    4.3 volvo penta flywheel problems

    What about the difference between automatic transmission flywheels and manual transmission flywheels? Did you use the flywheel from the original marine engine or the truck? I think with the VP style coupler the same bolts that hold the coupler on hold the flywheel on, unlike some Mercs.

    How to Switch to Antifreeze Cooled Engine

    The 4175 is a spread bore carb, the 4160 a square bore. Right now I think the Edelbrock 1409 is still on back order. Keep checking to see when it will be available, some of the Holley carbs are available, some you have to order & wait. PS looks like you can order the 1409 now...

    How to Switch to Antifreeze Cooled Engine

    Well your only options for a spread bore (which is the pattern for the original GM cast iron intakes) is a Quadrajet which has not been made in many years and good ones are very hard to find (but is an excellent carb) and the Holley 4175 which was intended as a Quadrajet replacement). Everything...

    How to Switch to Antifreeze Cooled Engine

    The bottom line is that boats that size if still running a small block should have a 383 stroker; the extra displacement makes a big difference. MPI on a boat like this where you are adding it on is a lot of extra cost and complexity for very little gain. It’s not the same thing as if you bought...

    How to Switch to Antifreeze Cooled Engine

    There is just no need for EFI on an old boat just use a good 4 bbl carb properly jetted for that application and it’s going to give you the most you can get from a big boat with a small engine. EFI conversion is just not cost effective on an old boat. Don’t make your life more complex than it...

    How to Switch to Antifreeze Cooled Engine

    I have it propped to hit 5,000 rpm wide open (15.5x15 prop) so I’m only getting approx 35-40 mph wide open but due to typical choppy conditions in the local bays where I boat low speed responsiveness and acceleration on plane is more important to me than wide open top speed. IMHO this boat...

    How to Switch to Antifreeze Cooled Engine

    You’re got a little Chevy small block that used to come in a 4,000 lb Chevy Impala/Caprice full size car of the 70s/80s/90s in a large boat so your fuel economy is not going to be great no matter what. I would also recommend a 4 bbl carb on that engine because you will have better low end...

    1994 Volvo Penta 5.7 GL Timing Setting Procedure

    These are 2 different systems; the BID uses an electronic module but a conventional centrifugal advance set up like that used with points vs the Delco EST which also uses electronic spark advance. The Delco requires the special procedure whereas I do not think the Prestolite BID does because of...

    TCW3 Oil and Non Outboard Applications

    The only applications that I know of where TCW3 is recommended for an air cooled 2 stroke is in Toro snow blowers and Lawn Boy lawnmowers. For everything else use the 2 stroke oil for air cooled 2 strokes. Reason why is that the air cooled 2 stroke oil has the low ash formula vs TCW3 which is...

    How to Switch to Antifreeze Cooled Engine

    while good boats are hard to find due to market etc, you'd be a LOT better off, waiting till you can water test any boat you might want to buy. What you're doing is risky, even if the boat is very low priced.

    How to Switch to Antifreeze Cooled Engine

    two euphemisms about boat buying: "I was told" "I recently acquired" both can get you into a lot of trouble! A boat that age, can have so much wrong with it, that if you don't have someone who is familiar with wood/fiberglass composite construction you might be making a big mistake. The...

    Four Winns 200 with outboard ?

    Yes they did come with outboards, go on to their website and you can download old brochures to see what the boats looked like. https://www.fourwinns.com/uploads/2017/2/Catalog-1996.pdf in the H200 section they don't have a pic of the outboard model but they do list the outboard choices....130...

    How to Switch to Antifreeze Cooled Engine

    you want to REALLY make sure it's a Merc Alpha and not an OMC Stringer. I have a later Cobra and there are very few places who will work on them, and parts you have to search for. DO NOT buy if it's an old OMC drive! and far as the salt water discussion, you just get used to the extra...

    How to Switch to Antifreeze Cooled Engine

    If you are going to run a raw water cooled inboard in salt water, the exhaust replacement every 5-7 years is standard maintenance. If you go with full closed cooling, then you won't have to replace the manifolds only the exhaust elbow. Keep in mind that for full closed cooling you may have to...

    How to Switch to Antifreeze Cooled Engine

    I doubt this is any Pontiac 301 engine, very unlikely to be ever used in a boat, if its a Ford/Merc I/O It could be a Ford 302, if an OMC same thing both used Ford engines then, in addition to GM, which could be a 302 (5 liter). As far as putting a closed cooling system on a salt run inboard...

    Air don't freeze... RV antifreeze DOES!

    If you can find the Sierra PG antifreeze and get a refractometer (for PG antifreeze/water mix testing) you can get better antifreeze protection for less than the cost of -100 PG. I have been using this for a few years now.....
