    Video: What The Heck is This?? - 1999 VOLVO 4.3 GL - 2 bbl Holley Carbureted, ETS ignition

    I'm one of the few who has an old breaker points & mechanical advance distributor you can check it with an advance timing light.... old school tune up circa 1966 tech lol. Glad I didn't throw out my old tools. I have a couple of spare 4.3 distributors, new points plate and new advance springs.

    Video: What The Heck is This?? - 1999 VOLVO 4.3 GL - 2 bbl Holley Carbureted, ETS ignition

    How are the 2 engines plumbed from the tank? Two lines coming off the tank, one for each engine? I've never had a twin engine boat but I think with 2 separate lines each should have their own anti-siphon valve. The whole point of it is, to prevent fuel from siphoning out of the tank if the fuel...

    Video: What The Heck is This?? - 1999 VOLVO 4.3 GL - 2 bbl Holley Carbureted, ETS ignition

    Start at the beginning of the fuel system, anti siphon valve on the fuel tank, & fuel tank vent. If the anti siphon valve is corroded internally and sticking, or is partially blocked with crud this can happen When you installed the new Holley, did you check the float setting? Their quality...

    Saltwater corrosion = can't remove part

    Carefully applied heat and a cotter pin extractor. You can also try one of the many penetrants like freeze off, kroil etc. I used this tool removing the 4 cotter pins from He11 when I replaced my steering actuator on my '88 Cobra and those weren't even corroded!

    I think they have accepted a syn blend as the best for marine engines but not full syn.

    Starting Dry

    Rubber impellers must be lubed When I do my first start of the season I put on the muffs & turn on the water. Then I disconnect the raw water intake hose & fill it full of water this puts water right in the impeller housing. This works perfect it primes instantly.

    MerCruiser single point drain leak.

    Instead of that Rube Goldberg-ish maze of hoses & plastic they SHOULD have just made at least a half closed cooling system STANDARD! If you want to get a headache take a look at the parts breakdown on a modern Merc 4.5 just for the raw water cooling system. Somehow my old OMC Cobra made do with...

    MerCruiser single point drain leak.

    These things seem to work OK when the engine is new but as it ages, cast iron naturally sloughs off rust flakes, that wind up clogging drain ports. That is the problem with these systems. On my boat I reconfigured the rear of the boat to make the engine more accessible so that I could have...

    01 horizon 180 inquiry

    as long as the base under it is in good shape, all you need is the foam and a staple gun. Not a hard job, I had to replace the bases on most of the seats on my boat and the big sunpad as well.

    GY Endurance is load range D in that size. That’s probably the best tire you can get now.

    trailer tires

    I’ve been using those Kenda Load Star bias tires for years. Only local towing though but no failures. I change em when I see cracks starting. Usually 6-7 years. I prefer bias tires for my use…narrow driveway narrow ramp is tough on sidewalls & bias sidewalls are stronger than radial sidewalls...

    Yes the Cobras are slit on the bottom to reduce exhaust back pressure at idle speed.

    FELL Marine MOB+ Install

    The way I read the law this was for new boats but you don’t have to retro fit it to older boats unless you want to.

    Volvo Penta Drive Belt - Lots of dust and quickly wearing??

    Well it could be that, I would put an amp clamp on your Alt output to see what it is putting out, you may need a higher capacity alternator. If it is being pushed to max output all the time that could be it.

    01 horizon 180 inquiry

    Sorry to say that may be the only way, unless you can find something from Great Lakes boat supply they sometimes have discontinued stuff. If I were you I might just patch it the best you can and get it done in the off season.

    volvo penta 3.0L exhaust manifold leak test

    Very good now you just have to dress the sealing surface between the manifold & exhaust elbow. You can use a mill bastard file or a sanding block with 80 grit sandpaper. Then check the flatness with a straight edge & feeler gauges you want it to be less than .003” thickness variation. Preferably...
