I am trying to revive an Arnolt Sea Mite. It is a NOS still in crate motor that is missing a few items however the most critical is the water pump (w/pulley) and bracket. The motor has the bracket but is broken. If anyone is parting one out I would love to hear from you.

Further I would appeal to you for any available information on this engine (and/or) company. Literature, photos, manuals, specs etc. Who knows, someone may still have the old engineering drawings laying around (worth a try (smile)).

I spent the day in Warsaw In. trying to research some of the history of Arnolt. I found their plant in Warsaw and the one in Pierston. The plant in Pierston is crumbling but the one in Warsaw is newer and vacant but up for sale. I believe that marine engine production took place in the Pierston plant however I need to dig a lot further in order to even confirm that. I don't know why but I have a great interest in the history of Arnolt. There is very little available on the web, most of it is about Stan "Wacky" Arnolt in his later years and his association with the Arnolt Bristol (automobile).

I would also like to put together an Arnolt (marine engine) owners registry. Anyone interested please e-mail me with your serial #, condition, what the motor is installed in (if installed), transmission type, a photo attachment would be great and any other information that you would like to provide. I know that people don't like to forward name, phone and address info so I will register by e-mail address if you don't feel comfortable providing that information. I would ask however that you include your city and state for geographical tracking only.

I found an article on the web about Mr. John Hacker and his "Doodlebug" which he was to have used the Arnolt Sea Mite in. If anyone has any more information about that I would like to follow that track too. It's a really smart looking craft. ref: http: www.dngoodchild.com/5402.htm

my email address is ramounteng@netzero.net

Thanks!!!

Hey andrew this was obviously a small company,and the engine looks modern factory made.Is it possible that they used Waukesha ICK moters as the base and they just marineized them.the specks are 61ci and 18hp at 2600rpm.Just add 200 rpm and it would be 2800 and 20hp.If its the same engine parts would be much easyer to find.If ramounteng could post casting numbers or more pictures I might be able to confim the id.

Larry,

I would guess you are right... they probably didn't build their own block... although I think they did put out a lot of engines for WWII life boats and small gen sets.

Gil Plumb rebuilt one last winter so we can ask him. He is away for a week but I will check with him when he gets back.

ramounteng has obviously done his homework... he probably knows. Maybe he will tell us here.

Thanks for the response!!! First of all I need all the help I can get on this. I haven't yet pulled the head however I did get two NOS pistons that were supposedly used in the Sea Mite. They measure 2-1/2" dia x 2.35 long. I also got a NOS Zenith carb #S168B which does match the carb info that I found on a related web site. The block has a casting #121220A and the head has a #121002B with the number 211 below that. I could find no other numbers on the block. I seriousely doubt that the water pump from an industrial motor will work because the pump on the marine engine would need to be the suction type of course. Larry, from what I have been able to find out I tend to lean toward your conclusion that the engine might have been cast by Waukesha. From my observations neither plant in Pierston or Warsaw appeared to have been equipped with casting capabilities. I am not even sure that they might have had a forging oven which leads me to conclude that they probably outsourced their forgings as well. I have attached some photos for your parusal. Hope you can make some positive I.D.

I took some photos but cannot get them to upload because of the 50k limit. I will try to compress them later but don't think that will work. I could e-mail them if you like. Let me know.

You need to "reduce" the photos in any photo editing program. "Compressing" them does not work.

Normally waukeshaw added lots of extra pat. and casting numbers.But they may have left them off because it would be sold as an arnolt.Haveing an A or B at the end was common on the ones i have worked on.I am more familar with the larger engines.I do have the piston spec's.Diameter 2 1/2 piston pin diameter.625 compression rings .156 thick.

Yea! I tried to reduce them but still cannot get below 50k. I dug out an old low res camera and re-shot the photos. They aren't very clear but you should be able to identify something.

Larry_from_Maryland, The wrist pin is .625 and the oil ring groove is .159 however the compression ring grooves measure .127. Also the pistons are full skirted. What type of head gasket did the Waukesha engine use? I ask because if I cannot find one I will need to hammer one out myself if it used standard fiber material. Don't know what to do if it is composite. The rest of the gaskets I'm not worried about. The seals should be available from Bearing Service

I may have gone up a line when reading the ring spec. from the table.All the ones that i worked on had the normal head gasket with 2 metal pieces and some stuff in between.Waukeshaw is now part of Dresser industries.I believe a fellow told me he got a gasket for a smaller wauk. from Arrow gaskets.I have been unable to find a good picture of an ICK.

I have a small Waukeshaw starter engine, four cylinder, no water pump, looks like these engines. Is it similar?

Larry & Andrew, I found another casting number. This one is on the cylinder block. The cylinder block is separate from the crankcase. The other number I gave you is on the crankcase. This number is on the flywheel end as follows; 112101, below that is a number 30420, below that looks like ALLOY 21 and to the right is 2- in a box and below that is a large letter L. I hope that between these numbers and the (poor) photos you can positively link this engine to Waukesha. Thanks for your help.

Robert,

I do have a larger version of it, I will email it to you. Also, Arnolt did quite a lot of advertising. Shouldn't be too hard to locate various ads in the period magazines.

The other side of this building faces Highway US 30 and had affixed to it's outside wall a large sign in the form of individual letters which spelled out "S.H.Arnolt Corp(oration)?" At night the letters lit up, in red I think, and I can still remember this image vividly from much earlier years as I'd drive to or from Warsaw (I worked at Hoosier International Motors) to North Manchester, Ind., my home. I believe that during the 50's/60's aircraft ejection seats may also have been made there.S.H.Arnolt plant at Pierceton, Ind. 2008
