DEW 4hp marine engine with Schebler carb. Owner & restorer Mark Abner from Louisville Kentucky. Very early engine with the 4 hole flywheel probably manufactured sometime between 1905 to 1908. Nice job on the restoration Mark, I especially like the way you did the cart.
Dew Twin Marine. Owner? 9-10 hp
Dew Marine sold on Ebay. Owner? Hp?
This Dew Marine engine was auctioned off on Ebay a few years back. Owner: Un-known, Hp: Un-known but I believe it is a 2 hp. If you know who the owner is please email me. I believe this engine to be one of the oldest DEW marine engines in existance. The first DEW marine engine advertisements started showing up in 1906-1907 with the 4 hole flywheel. Also proof that this is a very early engine is the small 3/4" threaded inspection plug and the location of the exhaust hole being higher up in the manifold and last but not least is different style brass name tag. This style tag was on the very first DEW marine engines.
Detroit 2hp before and after restoration photos.
Owner: John Davis from St. Cloud, Florida. Bore: 3 in. Stroke: 3.5 in. Crankshaft Dia: 1-7/32 in. Weight: 100 lbs.
Carb: Lunkenheimer with throttle control. Notice Grease cup on the crankshaft for lubricating lower con rod.
Most of the Detroit's used oil to lubricate the lower con rod bearing.
This is a good example of an early manufactured DEW marine engine with
the small 3/4" pipe plug hole for crankcase inspection and no
balanced flywheel or crankshaft. Also has the early style brass name
tag. Engine manufactured around the 1905 to 1907 time period.
