Just put varnish on it.

Since the gear pump will not prime by itself. Its worn out. Also since it is leaking past the shaft seal it worn out. The pump more then likely has an open shaft bearing bearing. Which will allow the water leaking past the shaft seal. As the leak gets worse all the water will not be able to leak out...

Is the water pump a gear pump or a rubber impeller pump?

Might be best to post a picture of the pump.

Pertronix used to have great coils. But about 5 to 6 years ago they moved production to China and they became pure junk. I went back to using NAPA coils. You want an IC14 coil from NAPA. If you have a external resistor get rid of it. All they do is cause problems on boats. The NAPA coil doesn't need...

The IC 14 is an internally resister coil.

So no external resister needed.

You want NAPA number IC14

Since you still have points. Go to NAPA and get a 12 volt internal resister coil. Buy the top of the line.

All the other auto parts stores sell coils that are junk.

Do you have a Pertronix ignition in your distributor?

For the F series?

Mcmaster Carr has DOT compression fittings (not yor-lok fittings) and the nuts look just like the original compression nuts.

I'm rebuilding a 430 right now. They are a very expensive motor to rebuild. Most of the internal parts are no longer available so you have to track down new old stock parts. Also the combustion chamber is in the block so you have to find a machine shop that has the jigs to bore the cylinders. Think ...

You can tap the inside hole of the bailer with a 1/2 inch pipe tap. Then install a brass pipe plug with JB Weld on the threads. Then put the hose and bailer on. Done this way it will look completely original. It should have a hole at the very top of the loop. smaller then a 1/16 inch. If the hole is...

There is a factory memo that has the exact date the plates change over to R&P screws. I know the year was 40 or 41. I think Don Danneberg has a copy of it from the Mariners Museum.

The original hole will do fine. Just run the same size drill bit through the hole to make sure its completely clear.

If the fuel bowl gasket is over a year old. They usually won't reseal after the bowl has been removed. The cork ones get hard. Rubber ones leak. I think its the additives they put in todays fuel. Which are the same whether it has ethanol in it or is ethanol free. You can get a sheet of cork gasket m...

The 2 with a big hole in the center mount on the deck framing. The 2 without a big hole in the center go on the hatch to keep the rod from backing out.

The starboard engine has an L stamped by the timing mark. Could it be possible the engines have the the wrong flywheels on them. What degree setting should I use to check the timing? Thanks Dave The L means left hand. So I would guess you have the flywheels on the wrong engines. If that is the case...

You have to have the casting number for the foundry to see if they have one.

If your 327 flywheel forward conversion is the 283 Chris Craft conversion parts. It should drop right in. Chris craft designed the flywheel forward engine to drop in on the same mount block using the the same front holes that the K used. When it rest on the original blocks it will be very close to t...

Thats a simple fix. Get a package of spark plug index washers. Put shipping tape on one side and cut the center out. Put some JB weld in the pit and put the washer on tape side down. Then screw the spark plug in. Wait a few minutes then unscrew the spark plug by hand while holding the washer down wi...

I guess I'm still out to sea regarding engine oils. Brad Penn 30 wt high performance oil and Rotella straight 30 wt oil both seem to indicate that they are detergent oils. Is this true? I prefer to use a single grade non-detergent oil in my M-27 engine as I can only assume it's been a long time sin...

The 70's and 80's Correct Craft trailers are perfect for this boat.

One of the posts regarding the use of Brad Penn 30 wt engine oil in classic flat head engines was to make sure you don't use Brad Penn 30 wt break-in oil. The only thing I see different in the oils is the addition of proper levels of ZDDP in the break=in oil. Is there harm in using the break-in oil...

Definitely homebuilt. It has an engine bed for the motor. It does not have stringers which run most of the length of the boat. The boat will probably flex a lot since there isn't anything tying all the frame work together.

The Barrelback will be the best riding one. The Racing Runabouts where built for speed. Flatter bottom so they are rougher riding in choppy water.

Thanks for all the input, FYI when spinning the pump with a priming tool it does not allow you to build pressure because with the tack drive removed there is an open oil gallery passage , you can see the oil pumping but you will not build pressure. Incorrect. You were probably spinning it the wrong...
