Re: Rebuild or Repower

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 ...

Re: Self bailer vent hole

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...

Re: SCREWS

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.

Re: Another boat that needs ID help!!

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.

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.

Re: 283 engine ID plates

Those are drive pins. Not rivets. The best way is to cut a slot in the head with a dremel tool and try ti unscrew them out. The shanks have a twist to them. So when they are driven in. They twist in like a screw.

The 17' footers had them also so make sure you ask for the length you want. I have in the past seen some with dark green but I think that was either a 22 or 23 foot triple.

The detergent oil keeps the dirt particles suspended. Run your engine and get it good and warm then change your o...
