    Need advise on bringing a 92 beretta succsess 200 back to life.

    that hole is part of the choke heater set up. The way it works is that air is drawn by vacuum into a tube that is in the exhaust cross over in the intake and that then heats the air, the hot air opens up the auto choke valve by unwinding the thermostatic spring in the choke housing. I haven't...

    We all had to learn somewhere. I remember running out to pull the drain plugs the first year I had my present boat (this was back in 2002 or so) lucky the previous owner gave me the OMC owners manual which described it all very clearly. Since then I pick a nice fall day in October to winterize...

    as my previous mechanic used to say "I'd rather have my Chevy small block in a hot rod than in a boat" and here they refer to I/Os as "double trouble"! Yep stick to outboards in smaller boats. Better in every way except initial cost.

    your benefit will be to find out if the engine heads/block/intake is cracked and where the cracks are if you can hear air escaping. But since you didn't drain it then get ready to go shopping for another engine. Because what you described doing will not get the raw water out of the engine and...

    No it does not, the engine, & intake are still full of water! the only water that drains that way is what's in the manifolds (not 100%) water intakes of the outdrive Outboards drain by lowering them down all the way inboards and I/Os must be drained. So there is still about 4 1/2 gallons of...

    Then how did you winterize it? There is a drain on each side of the block one on each manifold and you pull the lower end of the big hose at the front circulation pump. Each drain hole has to get poked with a pick or thin screwdriver due to rust flakes clogging the holes sometimes.

    Before you start taking too much apart learn how to air pressure test your cooling system. The thermostat housing has to be in place to do this. In fresh water I doubt your intake rotted out, it happens here in salt but even so I’m still using my original 1988 intake used in salt about 20 years...

    The GM small block is pretty robust, usually when this happens its either freezing water got trapped somewhere and cracked a head, intake or block or a past overheat weakened the head gaskets and you get water in the oil. Salt or fresh water? Any overheats in the past?

    Looks like you blew a head gasket ou have a cracked head. Time to check compression and air pressure test the cooling system.

    Riser Extension Blocks - Full Closed Cooling ???

    What about the gaskets for the ones with the 4 channels connecting the larger water ports? I'm thinking they might be more prone to leak which is always a concern with wet exhaust joints.

    Replacing batwing manifold questions (and other questions)

    Sure thing. If you want the paint to last: after removing the paint from the sealing surfaces of the manifolds and elbows (where the gasket goes) paint the with Rustolieum black with a brush much less messy than spray and that paint will last with no rust the next season. The thin coat of spray...

    Overhauling my 1988 MerCruiser 4.3 ltr. engine

    I think the Mercarb is a re-worked Rochester 2GV 2bbl carb. If you want to really wake up that sleepy little 4.3 next time try a Quadrajet, Holley 4160 or an Edelbrock 1409. Of the 3 I am most familiar with the Quadrajet which is such an advanced design it functions as a variable venturi carb...

    Maintenance on garboard or brass plug that is leaking.

    Main thing with a job like this is to deal with any possible wood rot. You want to dig out as much as you can and dry it all out, and fill with thickened epoxy. Then when installing your new garboard drain I'd use 3M 4200 to seal the opening and screw holes. The best way to deal with the screw...

    Opinions on shop's quoted Bravo 3 maintenance cost

    not only that here's the bizarreness of it: diameter measured in inches lug nuts in fractions of an inch in certain cases but at least 19mm = 3/4" trailer lug nuts are still 13/16th like in the old days! tire section width in mm but wheel diameter in inches as an example: we have a 245(section...

    Opinions on shop's quoted Bravo 3 maintenance cost

    not only did I have to pick up an 18mm socket but I also picked up an 18mm ratcheting box end swivel head wrench for certain jobs where it just fits in better. "there is nothing so pleasant as just the right tool for the job"

    Maintenance on garboard or brass plug that is leaking.

    Yep this might be where you get to learn a bit of fiberglass/wood repair. Hopefully there is not much wood rot in the core of the transom. I would dig as much out as I could and really dry it out as much as possible before refilling with thickened epoxy. Then make sure to seal the opening and...

    Overhauling my 1988 MerCruiser 4.3 ltr. engine

    Agreed that’s the main thing it’s not a super critical spec esp with raw water cooling there is not much pressure in the system. I’ve see Merc Perfect Seal, OMC gasket sealer, Permatex thread sealer and Permatex Aviation all recommended for this application. All are non hardening sealers as far...

    Overhauling my 1988 MerCruiser 4.3 ltr. engine

    don't forget to use sealer on the head bolt threads. I used Permatex Aviation.

    Leaving I/O in water all year round?

    I did both the bellows on my OMC Cobra (no need to do shift cable bellows, its inside the boat like a Volvo SX) and total parts cost was about $100 bucks with OEM parts. Took me about 3 hrs total. Glad I have an outdrive jack and the correct tools including an alignment tool. If you store the...
