I’m restoring a 1935 CC 19ft runabout, originally outfitted with a Crown (# 6a 1783 6a (6’s maybe “G’s”))as per paper work. That’s long gone and I would like refit it a Crown of some sort but know nothing about them.
I have seen references to all sorts of model numbers and model years and would like learn what they correspond to (hp, displacement, # of carb, etc) .Can any one enlighten me a bit or point me in the right direction for info?
Regards. PK |

Chrysler #6 engine 230 ci, 63hp @ 1800rpm, this from a 1946 book. The same ci engines were upgraded and came out with larger model numbers higher compresion ratios and more hp. |

THanks Larry,
That motor won't be missed, No wonder someone replaced it with a Herc.
I wonder if the later crowns with more resonable hp look enough (or can be made) to look like the early ones.

Not so fast pk4
That's 63 hp at 1800 rpm.
In today's terms where engines are rated at 4500 rpm, the hp would be about 160 .
For a 19 ft runabout 1935 vintage that's about right. You won't get up on a plane but I suspect it never was designed to do that.
I get a lot of fun out of going real slow and just cruising along.
If you want to have a fast boat, get a tupperware boat or a jetski. |

Personally I look forward putting around the bay down here, listening to s big six burbling away. Tying up here and there for a coffee. Drifting along pecking at my laptop…
With that said, I also used to love water skiing, would like to start again and if I’m going to have a boat…why not make it as flexible as possible while retaining it’s mid century charm.
I take Issue with your hp calculations, My car is rated at 270 @ it’s 6700 redline. That’s the way it’s old. Same with my other cars and same with every “write up” I’ve seen;;; hp at redline, not 4500 .Hp calculation requires something like a fixed load from idle to readline.
I have learned that the basic crown puts out 95 hp at it’s readline of around 3100 rpms. The herc redlines around 2100 rpms where it hits its max hp. At 4500, Both engines would be throw parts into orbit .
Why not get a jet ski? I like the look, style, romance and functionality old runabouts.

Bob Speltz Real Runabouts Volume II; Page 180 lists the 1935 CC 19' Runabout with either a Chrysler Ace-PC rated at 70 HP turning a 12X 14 prop(CC PN#7526). Also listed is the Chrysler Crown-CA rated at 92 HP turning a 12x14 Prop(CC PN# 7526).Not listed for the 19" but available in the 22" runabout is the (exceedingly rare engine)125Hp Chrysler Imperial-LM for 1935 turning a 15x14 prop PN# 7514. |

Thanks, that’s some very interesting information. Through some cross referencing, my motor appears to have been a 95 hp.

Most likely you had a CA they were produced from 5/2/34-3/9/36 there were 555 units produced. 93HP@3200RPM Serial numbers were from 1301-1855 |

Thanks
Well, my paper work says "6a 1783 6a" (":6" could be anything that resembles it). So that would Identify it as being th the range.
But a number on the block of engine I removed is 40381. At some time I through I had identified it as a Hercules.
Regardless, It's rusted throough so I have to find a crown. (Or a K if I find out what its about)

I take that # back. It was on the block. On the manifold it's LC 8311. that rings a bell as it being a garden variety Herc.
So now I need a crown.

Can you post a photo? "Generally" Chryslers have rectangular tappet covers where Hercules are rounded on the ends. The LC 8311 on the manifold, is it cast in or on a brass tag? |
