Re: Recommended KBL Engine Oil

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...

Re: Recommended KBL Engine Oil

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...

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.

Re: Best Chris Craft- Barrel back or racing runabout?

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.

Re: 1959 CC Ski 18' 283 has low oil pressure when started cold some times but others it jumps right up to 30-40.

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...

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.

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...

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.

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 ...
