    can someone tell me what motors are in a 1987 28' Chris-Craft 283 Amerosport 262 ?

    Well if you ask on here, you will get mixed opinions on getting rid of points. Some like the Petronix system some have had repeated failures. I kept my points because I know how to set them up and no electronic mystery boxes to go wrong. If you have a Prestolite, they aren't hard to change...

    HELP! 1988 4.3 omc had water in the oil.

    The exhaust manifold having a crack, suggests that the past owner didn't drain it, and if one thing is cracked (as easy as those manifold drains are to get at) then other things are likely to be cracked. Personally I don't have the patience at all for fooling around with other people's old...

    Volvo Penta 3.0 I/O Overheating. Brand New Engine!

    You're welcome! If you need engine electrical stuff like starters or alternators I can recommend ARCO I have both on mine. Better than the off brand cheap stuff. If the battery is very weak and won't hold a charge, the charging rate in volts on the dash gauge will tend to be low. Check battery...

    can someone tell me what motors are in a 1987 28' Chris-Craft 283 Amerosport 262 ?

    The older V6s do take GM parts for all the internal mechanical parts but the front water pump will be a marine Chevy small block pump. If the engine uses open cooling (no heat exchanger) you have to use a marine pump with better quality parts inside, if you have a heat exchanger with antifreeze...

    Volvo Penta 3.0 I/O Overheating. Brand New Engine!

    PS Here’s a trick I use to make impellers last longer, by avoiding a dry start on the first start of the season. Hook up the muffs & turn on the water. Then go up on the engine and disconnect the hose from the impeller to the stat housing at the stat housing. Now fill that hose with water with a...

    Volvo Penta 3.0 I/O Overheating. Brand New Engine!

    That’s great to hear! I guess some impellers have to be installed that way. On my Cobra they have always been self-correcting. I also would lube with a bit of Dawn dish soap which maybe helps the blades flip the right way. Normally mine runs at 160, it might rise to 170-175 after coming off...

    can someone tell me what motors are in a 1987 28' Chris-Craft 283 Amerosport 262 ?

    Is 262 the cubic inch displacement? If so they could be GM 4.3 V6s. Engine parts are GM but the add ons are from whoever marinized the engines. Older Chris Craft engines were blue like Crusaders I think...

    Edelbrock 1409 hard start, flooding

    Agreed with the engine off it really can’t be the pump.

    Edelbrock 1409 hard start, flooding

    Well it might be a good idea to check the pressure on that pump; although there is still a chance that you have an intermittent float sticking issue.

    Edelbrock 1409 hard start, flooding

    Also: If it floods that bad with the engine off are you sure that the oil pressure safety switch & wiring are functioning correctly? An electric pump MUST SHUT OFF as soon as the ignition is turned off! The electric pump must be wired correctly to an on/off oil pressure safety switch so if the...

    Edelbrock 1409 hard start, flooding

    That would suggest that the needle valves are holding. I’d try it several times to see if they hang up. If not I’d measure fuel pressure to make sure it’s not higher than specs. It’s possible for a fuel pump to deliver too much pressure in a carb application. Check what Edelbrock says but I...

    Edelbrock 1409 hard start, flooding

    Something about the floats contacting the side of the fuel bowl. Might have to check clearances carefully. All carbs have their quirks. Right now I’ve learned most of the Quadrajet ones but when they are clean and properly set up they are really good. We owned a ‘75 Olds with a 350 and a QJet...

    Preignition knock under a load 2000 Thunderbolt 5

    What do your spark plugs look like? Light tan or grey or blistered white? If the latter that’s a clear indication of a lean condition

    Outdrive does not want to re -install in boat

    I think the keys to doing this job: Drive jack to get the drive at the right height Proper alignment and lining up gimble bearing with the tool as mentioned A means of turning the driveshaft just enough to make the splines line up. You’re talking like maybe 1/8–1/16” here... That’s whats...

    Edelbrock 1409 hard start, flooding

    I never had an Edelbrock but I heard that the floats can hang up. On my Quadrajet both times I had that problem it was the needle valve. Easy fix once you got the air horn off. I also had flooding similar with a Holley due to a piece of rubber from those fuel transfer tube o rings holding the...

    Edelbrock 1409 hard start, flooding

    Agreed in the second vid is the engine off? It’s REALLY flooding prob a piece of grit between the needle valve & the seat. A possible quick fix is to remove the carb and drain out all the gas & let it dry out to be safe. Then with the carb level blast a bit of compressed air thru the fuel inlet...

    restoration of 1991 VIP and engine upgrade inc conversion from spitfire ignition

    You need a decent digital volt ohmmeter and the specs for the Delco EST system, it shouldn’t be hard to find because Volvo Penta used that same system for years. I don’t know off had because my OMC still has the original points system which works fine if you know how to maintain them.

    Impeller housing overheating

    Starter terminals, battery terminals and battery cables. All must be free of corrosion clean & tight. Sounds like resistance at the terminals/corroded cables. Any bad wiring or terminals in the starting system can cause this....
