    Everything done but low rpm at WOT. Distributor spring?

    An Edelbrock Marine 750 from Summit or Jegs should do the job. Summit’s #. EDL1410. @ $575.95. Have you checked inside the exhaust system for any blockage such as any exhaust shutters or even a rag could cause this kind of problem. Will the engine free rev in neutral? If so then that would rule...

    Dean's List gets another motor

    Too bad you could not get a 3/4“or 1” impact with enough air to power it. I replaced one on a smaller boat at my shop one time and it had me “blessing “ it! And I had compressed air an impact wrench and a torch.

    Slave solenoid does nothing

    With a test light probe the #10 y/r on the slave solenoid while someone turns the key to start. Sometimes the slave solenoid will click but does not make an internal connection. If it lights then test the same same colored wire on the main starter solenoid. If it still lights then either the...

    MC-1 Cylinder Rebuild Questions

    When you remove the lock nut be very careful as there are small springs on either end and the check valves are in 2 pieces, be sure they go back on the way they come off. After the valves are off remove the rest of the parts from the rod. Screw the cover nut on the ram tube and bang it on the...

    High compression in 1 cylinder - 7.4 carb

    You may have a camshaft issue. As Flashback suggested remove the valve covers and watch the rocker arms on #8 compared to the other rockers. It might be a pulled rocker arm stud. Sometimes the press fit in the head is not tight enough. It is easy to drill and pin the stud in place.

    1972 Glastron v164 trim gauge

    Glastron boats were used in “Live And Let Die” stunts that were filmed here in Louisiana. The Jet boat scene where Rodger Moore crashed the wedding scene was the second one. The day before he hit a tree and knocked out his 2 front teeth on the steering wheel, so a set of teeth had to be made...

    Swapping gearing in a stringer outboard

    2005 350 Mag dropping fuel pressure under load

    I believe that is one of the Guardian modes. I might be wrong but it is worth a try. There also are kits that put the water intake on the transom so you do not have to go through the bottom. And yes you want both water supplies merged before the pump. I once had a Donizi with the 555 system...

    93 vp aq570 with 280 drive hydrolocked??

    The worst one I have seen is a piece as large as my hand blown completely out in that area. Then one that was a pinhole that was squirting water into the distributor housing causing the engine to miss and pop back through the carburetor. One thing about water, it cannot be stopped frozen or...

    Might have thrown away my remote oil filter setup....

    I see no reason why it would not work. Most standard marine engines did not come with oil coolers. The remote set up is good for relocating the oil filter for ease of service and less mess when changing the oil.

    2005 350 Mag dropping fuel pressure under load

    Bravo drives especially as yours is older are known to cause low water pressure. You stated that you were going to test it. That could be the whole problem. If it is, the best thing to do is to go through the hull bottom for incoming water connecting the drive’s water to the hull supplied...

    Swapping gearing in a stringer outboard

    This must be an electric shift drive. If it is then all electric shift models have the same gear ratio in the lower gearhousing. The upper is where the ratio is determined. The last 165 hp inline 6 was made in the mid 70s. Do as Scott said get the skeg welded on the 3.0 drive. Be very...

    Try to hook it up to an 6 gallon outboard tank for a trial run. As already posted, there is a good chance either the rubber fuel is collapsing or the screen in the tank suction tube is plugged.

    You just have to pry it off. There is a burr that the set screw caused on the spline. Be careful when reinstalling the set screw, it is possible to collapse the outer spline which will bind up the warm up pull out knob.
