    Replacement motor going in ,need opinions

    On your 1988 is the carb a Quadrajet? If so they use a well type choke which works with the pre-vortec just fine (these have an exhaust cross over in the intake to heat the choke & carb) but there is no exhaust cross over for the vortec heads/intake. So you'd have to either figure a way to...

    Quiet ticking noise

    Ok yes read your first post too fast lol. You might then wind up having to re-adjust the travel on the hydraulic valve lifters. Its a little confusing at first but not hard if you take your time. The exhaust will have to come off to get clearance to remove the valve covers. I did mine when I did...

    Quiet ticking noise

    If you don’t have a mechanics stethoscope I’d get one and try putting the probe on various areas and see where it’s loudest. Try it on the valve covers (valve train) and on the exhaust manifolds (exhaust leak)....

    MerCarb adjusting after rebuild and question about base gasket

    If there is no place to hook up a vacuum gauge you can also use an accurate digital tach to set idle mixture.

    Overheating after impeller change

    Ok on the Volvo if any impeller blades came off they could be lodged anywhere between the impeller housing and the hoses for the manifolds. I would take off the thermostat housing remove the stat and check all the water passages make sure none are clogged. Install a new stat in the housing (it’s...

    Rochester quadrajet

    Another issue with the QJet is when the secondary air doors open. If they open too soon then you get a stumble. On the QJet the actual secondary throttle plate is mechanical but the air doors above them are vacuum operated. There is a spring adjustment that controls the opening of the secondary...

    1986 Mercruiser 470 Starter & Fuel Pump

    Here's a comparison of the old direct drive style Delco starter vs an ARCO PMGR starter, the ARCO installed on my 4.3 V6 and the Sierra mechanical pump for the 4.3...

    Trouble reinstalling pre-alpha drive

    If you're over 40 and/or have a bad back and plan on owning I/O boats for some years this drive jack and the alignment tool are two things you MUST have. Because with out both there will be times where that drive will fight you trying to get it back on, both have paid for themselves many times...

    1986 Mercruiser 470 Starter & Fuel Pump

    The big Delco style starters had screens in them like marine distributors do. These do the same thing as the flame arrestor on the carb; if explosive fumes get into the starter the screen prevents ignition from spreading to fumes in the bilge. The small PMGR starters are sealed by design and...

    Trouble reinstalling pre-alpha drive

    Agree with all of the above and what really helps is to use an outdrive jack and get the bell housing and drive on the same plane with each other. You need to be able to hold the driveshaft as straight as possible as you guide the driveshaft into the bellows and then into the gimble bearing...

    New Boat Purchase - Stuck Manifold drain plug

    What you can do with replacing the manifold is this: When you get the new manifold it should come with new bolts. Take one of them to the hardware store and buy 2 longer bolts of the same thread/pitch. Then cut the heads off and cut a slot in the stub for a screwdriver. Clean out the threads in...

    Stripped bikini fitting screws in windshield frame

    As noted above be careful putting in bigger screws if the hole is next to a glass channel, if the screw hits the glass even just the edge of it that piece tempered glass will pop like someone hit it with a BB gun! now a stripped bikini mount, to me sounds like a wardrobe malfunction ;) I...

    Bellows sealant, DPS-A?

    OMC/Evinrude gasket sealer or Merc Perfect Seal or Permatex Aviation is what I'd use. Make sure there is no corrosion on the gimble housing flange.

    5.7 Riser - Clean and reuse or replace?

    Another good test after cleaning the old gasket material off is to lay a straight edge across it and try to slide feeler gauges under the straight edge. If a .001” won’t fit that’s really good. I tried this on a new set of Barr exhaust I installed 3 years ago and that’s what I found, less than...

    2007 Baja Islander 202

    Those core plugs rarely fail unless either the engine froze or, someone replaced the block and used automotive core plugs which will rot out in a marine application.

    5.7 Riser - Clean and reuse or replace?

    From what I can see in the pix they look good, but after you clean off all the old gasket material you want to see nice non-pitted cast iron on the gasket sealing surfaces so that the gasket will seal well against both the manifold and elbow (what you are calling a riser is actually an elbow)...
