Here are some pics of my Marinized Driggs-Seabury 4 cylinder flat head, circa 1913-1915? Any information anyone may have or resources that I can be pointed towards is greatly appreciated. I am in need of spark plugs with 3/4 inch threads on them, if you know of any, please let me know. Thanks a lot, Jon.

Intake, exhaust & valve side.
Magneto base & oil fill side.
Freshly balanced rotating assembly & cam.
Cast aluminum oil pan & rod dipper tray.
Bosch magneto & brass Tillotson carb.
3 of 4 reciprocating parts & misc.

None of the desciptions I put with the pics came through, so here they are.

1)Right side of motor showing intake, exhaust & valvetrain compartment. Brass bit is the piston pump that is run by the @1 exhaust lobe of the cam to oil the front gears.

2)Left side of the motor shows magneto base, water inlet/outlet, brass tube for??? & the tag.

3)Freshly balanced rotating assembly & cam.

4)Cast aluminum oil pan with rod dipper tray.

5)Brass Tillotson carb & Bosch American Magneto.

6)3 of the 4 rods & pistons, with one of the 4-bolt main caps.

Thanks for taking the time to look at my project, would appreciate any/all comments, both good and bad, (not too bad anyhow!). I'll have more pics soon, as I've painted the motor body and other parts, when I can. Take care, Jon.

Are your plug holes tapered? If so it would be 1/2 inch pipe threads. Value-bilt would have them

They had put 3/4 to 1/2 pipe adapters in the plug holes to be able to use the smaller plug size. I would like to go back to the original size for looks, but the few I've found so far are cost prohibitive. I'll look on value-bilt, hope they have a web site. Thanks Larry, take care, Jon.
