Re: 1940 19' Chris-Craft Custom: Orange Deck Seams

1939 6 gauge panel 1940 blue face individual gauges 1941 silver face individual gauges 1942 black face individual gauges. Most people don't realize this as there were very few 42 made. The above list is the basic time frame that the gauges change. Keep in mind with Chris Craft the year dates are mod...

Re: 1940 19' Chris-Craft Custom: Orange Deck Seams

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 orange deck seams was on purpose. The Mariners Museum at one time (probably still does) had a list of the hull numbers that were shipped from the factory with them.

Re: Recommended KBL Engine Oil

So, here is a question then. Was it because of better oil, or a change in engine design? Its fair to say that a pre war engine would have been a tad more loose? I ask this because is todays 30 wt the same as 1945's 30 Weight? I smell a story here. 30w is 30w. The additives in todays oil are much be...

Re: Recommended KBL Engine Oil

Straight 30 weight. The flat heads don't get hot enough for the use of multi weight oil. If the engine has been rebuilt recently i.e. Around the last 10 or so years. use a detergent oil. The detergent oil keeps the dirt particles suspended. Run your engine and get it good and warm then change your o...

Re: Rebuilt carb issues M27

Yep. A 1000 rpm at idle should give you around 700 to 800 in gear which is what you want. Also as Nemo check your fuel level. I doubt float level is causing it. unless its set way to low. In which case it should be running out of fuel at speed. When was it tuned up last? If its been a long time then...

If its a flywheel forward engine. You would pull the tach drive not the distributor to spin the oil pump with a priming tool.

I have also found that the hole in the gasket is smaller and doesn't quite line up with the hole in the block. I usually take a hole punch and make it bigger.

Re: Hull Year vs year on boat title

Boat production is the same as car production. The new model year typically started in August/September of the previous year. So the 1941 model year would start in Aug/Sept of 1940 and end June/July 1941. Remember years ago when the car dealers would start having the end of the model years sales in ...

Re: Starting issues

With the 6 volt electronic ignition you also need to keep the battery fully charged by keeping a battery tender on it. I would also recommend using the Optima 6v battery. It gives you the cranking amps of a group 4 but will fit in the group 2 box.

Do you have the small or big distributor?
