    Mercruiser 4.3 Vortec Backfire and no start

    That’s how I did my old Chevrolet 4.3 V6 after I replaced the cyl heads but I have the old Prestolite points distributor. That will get the distributor in the right position but I’m wondering if there is a special timing procedure with the Merc electronic ignition since they don’t use a...

    2006 Volvo 5.7 osi-d crank no start

    That or severe detonation, lean fuel mix, over propped. I think that’s more than a distributor cap issue. Look further to prevent a recurrence

    2006 Volvo 5.7 osi-d crank no start

    That definitely looks overheat related are you re-using the same heads if so did you get them checked for cracks at a machine shop? Both of mine were cracked and the cooling passages were getting eroded from raw water cooling so I replaced them with reman heads.

    Are we in trouble?

    The only way an I/O is the way to go: boat is old enough not to have complex and expensive cat converter exhaust owner knows and understand GM small block engines, can deal with difficult access and extra maintenance required by the I/O design and can do much of their own work Any other...

    Are we in trouble?

    If you don't want to worry about that kind of grief ever again, strongly consider not buying an I/O boat, you will be far better off with a late model boat with an outboard, especially in that size range. Less maintenance Safer Better performance Yes initial cost is more but well worth it.

    1987 Rochester quadrajet

    Usually mine will take about 2-3 crank overs before it fires after being stored for 5 months in the off season. Open throttle all the way to let the choke close pull handle out (if OMC remote control) and advance throttle about 1/3 to provide fast idle (marine carbs to not automatically set fast...

    Need help with transom repair...

    If you want to do it only once coat it with epoxy resin esp the edges then paint with several coats of paint to give the epoxy UV protection.

    Water coming in through exhaust

    VP removed those flappers in 1999 AFAIK so yours probably had em. However the way they were installed (they just used the original OMC Cobra design, same parts etc) there were 2 holes in the top of the Y pipe on each side. There were two grommets on the holes and a pin that the flapper rides on...

    Ouch! Well if I wound up with a Vortec V6 I’d have 25 more hp at least

    Connecting a electric fuel pump to 5.7LX

    Maybe switch the solenoid to a 4 terminal one that way you can wire it the way Merc did it originally. There are 3 terminal and 4 terminal solenoids. My old starter abs the new Arco PMGR starter I put in a few years ago both have 4 terminals. The 4th is not used on my engine because it has the...

    got a question about a future V6 to V8 repower...

    Given what’s happening in the world right now I might just stick with the economical V6-Quadrajet. Imagine what gas on the water will cost this summer. I could see it hitting 6/7 bucks a gallon at this rate…

    That’s one more issue with a project like this. Mebbe when the time comes I just buy a reman V6 short block & put my heads that I installed on the old block in 2017 on that…

    Carb choice.

    That’s true younger folks seem to think carbs are akin to witchcraft lol. It’s really simple actually Bernoullis law & pressure difference. Whether it’s a simple 1bbl on a lawnmower or three deuces on a big block V8. Old boats I’ll take carbs ANY DAY over EFI. Cost & parts availability. When I...

    Volvo Penta Steering Stiff

    Well if the cable isn’t stiff and there’s no play in the helm or steering arm it could be the internal seals in the actuator. These can be rebuilt even though VP says they can’t. They can be tough to change. I had to replace mine on my 1988 OMC which was leaking for a while. If you have to...

    Volvo Penta Steering Stiff

    How about in the hinge pins/steering arm on your outdrive & transom mount? I'm thinking that if the cable isn't stiff, then there may be play somewhere that causes you to have to more the cable more than normal to get the steering arm to move.

    Carb choice.

    I have never had the well plug issue nor a leaky float on mine. These happened on early automotive units but are not at all common on the Marine units.

    Carb choice.

    actually if you know where to look there is a ton of aftermarket support for the Quadrajet. www.cliffshighperformance www.quadrajetparts.com keep in mind for the youngsters here who weren't born yet that just about every GM car that had a V8, from 1966 to 1986 came with a Quadrajet, except for...
