    Should I replace my surge brakes with electric on my boat trailer?

    Electric brakes have more points of possible failure than surge brakes. With surge brakes if your actuator works, your brake lines don't leak, and your wheel cylinders/caliper pistons are not seized, your brakes will work. While electric brakes give the option of driver control over the braking...

    Should I replace my surge brakes with electric on my boat trailer?

    If you have trouble keeping your trailer lights working as many do, electric brakes while they are good in principal, could be just as much as a headache. I have found surge brakes WHEN MAINTAINED, even drums, to be adequately effective and reliable for my use. While I don't tow any long...

    2007 Volvo Penta 5.0gxi - no compression in # 4 cylinder

    Agreed as much as possible you want to know what happened to cause the failure. Have you looked under the valve cover to see if there was an obvious valve train failure? Removing the head is not difficult and if the cyl wall isn’t scored you may be able to run it with a reman head if the piston...

    2006 Volvo penta 3.0 glp-e misfire on cylinder 4

    You want to see that the sealing surfaces are not pitted and are flat and level when checked with a straight edge & feeler gauges to less than .003” thickness variation. Also clean out threads in the manifold so that the bolts get good clamping force when torqued. Follow the instructions put out...

    Why does my tandem axle trailer not have a backup solenoid?

    Drum brakes can be either free backing or non free backing. The free backing brakes have a single piston wheel cyl whereas the non free backing brake wheel cylinder has a dual piston wheel cylinder. If the trailer had an actuator with no back up solenoid it probably was equipped with free...

    Warning!

    And inspect your battery cables, for corrosion going from the terminal up the wire, which greatly increases resistance. Inspect and clean all return paths.

    1990 4.3 block and 1995 heads, which rocker tightening specs to follow?

    In the old days we’d go to the junkyard get a Chevy valve cover cut off the top half of it & temporarily install it that would keep the oil from going everywhere. Hard to do with marine manifolds in the way. The variations in parts with the 4.3 is why I just stuck with the original casting #...

    1990 4.3 block and 1995 heads, which rocker tightening specs to follow?

    The one I posted is right from my OMC shop manual which in turn is right out of the GM shop manual. I think you can trust that!

    Need Advice on Replacing Hubs, Drums and Brakes on Boat Trailer

    Dexter owns just about everyone these days....last time I checked they owned: Tie Down UPF Kodiak The last set of drum backing plates I bought were Tie Down, these came with a better design wheel cylinder that uses an o-ring seal instead of the boot that tends to hold water and cause corrosion...

    Need Advice on Replacing Hubs, Drums and Brakes on Boat Trailer

    The drums don't look that bad, unless the races are all pitted inside. I have used zinc coated drums and galvanized backing plates for close to 20 years with good results.

    2007 8.1 Gi converted to rear-mount closed cooling

    My vote would be to see if you can adapt Merc dry joint manifolds, they have the best design to keep out water, and can be used with full closed cooling.

    2007 8.1 Gi converted to rear-mount closed cooling

    now....if you have riser blocks....I wonder if those could be tapped for your top coolant exit? So your regular gasket goes between the manifold and riser block and the block off plate between the riser block and the elbow?

    2007 8.1 Gi converted to rear-mount closed cooling

    I have VP style manifolds on my OMC 4.3 and asked about this (full closed cooling) on this forum and Scott explained that you can't have VP style manifolds on a full system because you have to have 2 fittings at different heights on the manifold to allow coolant to flow in on the bottom of the...

    Warning!

    I do my own. They aren't rocket science lol. I remember years ago when we were kids and these carbs were on nearly everything GM made, we were told by the old timers that a Quadrajet was too complex for beginners like us to fool around with. Same with Autolite 4300s on some Fords. The Holley...
