I inquired on that as well. It is possible that he might have a marine 1-71. I have next to no images, or information on them. I have seen 1-71RA, 1-71RC, 1-71P, 1-71G, but never a 1005. Even the serial number is off. Usually it is A-XXX, not 1-XXX. I cant wait to see more pictures of the engines he has. 171-125 came out of New York and now resides in Colorado, the brother of Mbetti's #124.

The only picture i have seen of a 1-71 marine engine. It has a mechanical Twin Disc reverse and reduction gear. The 6-71 in the Navy LCVP used this gear box. AL[ATTACH]Click image for larger version

The size of that gearbox on that little 1-71
Reminded me of working at a performance shop years ago, we had an open house and one of our customers brought his roots blown mazda RX-7 rotary. The blower was as large as the engine, people were legitimately asking which powered which as it was so obscene

The most challenging part of my restoration has been the radiator The art of repairing radiators is in the past. Going to Honolulu tomorrow to check out a shop that was founded in the 40sClick image for larger version

Found a vintage fish cart at a estate sale. The tag said it came from Wilmington CA. On the side it is stamped M.S.Co. Does anyone have info on this? I have been looking for some steel wheels I can now build a cart for my little one lunger.Click image for larger version

Getting the fresh water pump operational. I machined a 2-71 seal and impeller assy to the measurements and angles on the 1-71 one. Spray welded the shaft to clean up the sealing surfaces. Also machined the cast boss in the pump housing to accept a stainless steel insert which i made. The carbon seal will ride on the insert and should seal in the coolant.

Did you do the shaft spray welding yourself or have a shop do it? Does it use an oxy-fuel torch and a wire feeder? I'm curious about the process as I've never really seen it done but have read about it a bit.

Thanks,

Kevin

Kevin, I had it done in a shop in Honolulu. I also have not seen it done. The advantages are you don`t have to compromise the tensile strength of the metal with excessive heat. That`s important on something like a propeller shaft that transmits load.

In the 1950's I used to operate a small freight boat from San Pedro to a camp on Catalina Island and one of the marine hardware suppliers was the Manhattan Supply Co. They might have been the source for your cart.

The boat I operated was powered by a Detroit 4-71.

My radiator restoration is not going well. I was quoted 2K to restore it. The out side dimensions including the top and bottom tanks are 12" wide and 18" tall with a fill in the top center. Inlet and outlet are on the back of each tank. There must be a similar size radiator out there used in a piece of equipment. Welding machine, Small tractor, Generator. AL

No i don`t. It is the engine oil cooler and i could hide an external cooler in the bottom of the radiator shell. I also found on line a aluminum radiator used on a ATV of approximately the right size that i could modify to fit.

Just did some in frame repairs ( in the boat) on a 6-71TI in Honolulu. Check out the name plate specs. 485 HP at 2500 RPM and a no load speed at 2700. It is using 145MM injectors. Talk about some screaming jimmys.Click image for larger version

Here is something you don`t see every day. The 1-71 engine oil cooler located in the bottom tank of the radiator. Have given up on trying to get the radiator repaired over here. I cut the core out and am ordering a new one from the mainland. I feel confident i can do the job myself. ALClick image for larger version

Got an early Christmas present. Its a one cylinder Yanmar marine diesel generator set. A friend salvaged it from a large sailboat that went up on the reef in the 70s. It didn`t get wet and had it stored in his garage all this time. It is not stuck. Wife says i can`t start on this project until i get the 1-71 running. ALClick image for larger version

I brought my radiator to a local mom pop shop that has been around forever. My core is ok but I asked him what it would cost to recore and he said probably $3-400.
