|
|
I just acquired a 1937/1938 Franklin 4AC-150 flat 4 cylinder, single ignition engine, mount, test prop, and manual. It came off a J-3 in running condition quite some time ago. Needs a few minor parts and a refurbished magneto, but all the essentials are there.
First step is to plug all the holes, clean it up, and get it in the basement (160 lbs) before the Chicago winter sets in. It'll take a while, but it will be runner. I'll post pics as soon as I figure out how to do so.
The adventure begins.

Amen to that, although I still need the hub "crush plate" and the through bolts. The original magneto is a shell, but I've got another magneto with the correct innards. I need to mix and match.
It's got aluminum exhaust manifolds, which are pretty cool looking, but not sure how common that is.

what are your plans? full tear down or just clean her up? are you going the trailer route or just a small run up stand? |

For cost, parts availability, and skill level reasons, it'll probably be a clean it up and try to run it approach. Depends on the compression test, too. The engine seems to be in pretty good shape with "good" compression by feel and no corrosion that I can find anywhere inside. I haven't gotten as far as mount or trailer design, but everytime I pass a personal watercraft for sale, I feel an urge to bid on the trailer. It would be the perfect starting point for a 180 lb, 50 hp, 44 inch diamter prop set up like mine. And I already have an airworthey mount for the engine, so that design and fabrication headache is solved. I took out the oil temp unit today, stuck the sensor in boiling water just for kicks, and son of a gun, 212 degrees F came up on the dial. Pretty exciting, but then again, I'm easily amused.

Alright, bad attempt at humor, that sounded a little creepy. I see your R-4360 and Jacobs pics on the website. I can't imagine the complexity of the Wasp Major, or just trying to move it around or handle the parts. Plus you need 28 or 56 of everything. But the cool factor is way over the top.
