Vintage marine inboard engines-Gray Motor Company Antique Marine Gas Engine

Marine Engines. We use Mercruiser inboards in our replica boats. These engines are powerful, economical and reliable. They install well and provide years of trouble free service. The Competition Ski series is particularly well suited to antique and classic boats where the height of the decks can be a concern on some vessels.

Unlike many restoration shops, Sierra Boat does all of its engine restoration in house. As a full service marina and boatyard, we have always had qualified staff to take care of the oldest engines to the newest. We can re-power your wooden boat in a way that still looks stock from the outside including a single exhaust and correct instruments.

We do this in a way that does not alter the boat and allows for the re-installation of the original engine if desired for show purposes. In addition, our machine shop can fabricate or fix just about anything. We also have a huge supply of old parts to keep just about any engine running. If we do not have it, we go on the hunt or have it duplicated usually with great success. Your email address will not be published. Leave this field empty.

Old Marine Engine

After asking a neighborhood farmer about old motors, he said, "none here, but follow me down the road to my other farm. It turned out to be a 3 HP, but the prize was what sat in front of it! Needless to say, we made a deal on the spot. It is water cooled, complete with a shaft driven water pump and commutator points with lever advance.

The oiler was missing and the two large grease cups were missing. Unfortunately, the spark plug was missing too so water had entered it. The good thing is that these engines had not yet spent the entire year outside in the weather. Once home, I sat the Gray on my workbench, opened it up and started soaking it with copious amounts of WD and Liquid Wrench. The Fairbanks "Z" piston came out with lots of WD on both ends over a long term and then by "chucking" the flywheel back and forth.

Further patience and WD loosened up the two rings that were still stuck in their grooves. The top ring was already loose. The Gray Motor's piston came out later. I had been able to get about 5 degrees worth of crank rotation by using the grease gun method. Pressurizing the combustion chamber by inserting grease through the sparkplug hole. This was after about a two week internal soaking with a mixture of kerosene, toulene, and xylene.

Keep in mind that this engine does not have a removable head for access to the piston crown. After achieving the 5 degrees of crank rotation, I had inserted all the grease I could find on my shelf. Three tubes and two containers of wheel bearing grease. Then I removed the engine base and drained away the remaining liquids. Next I hooked up the air compressor to the spark plug hole at the top, bringing up the pressure from 20 to psi, but that yielded no movement. I then took a pry bar and gave lift to the underside of the rod bearing cap screw.

At this point the engine was sitting in a horizontal position. Grease shot across the garage AND worse yet, my wife was standing in the doorway. She didn't get hit, but the garage floor did. This happened when the piston moved just enough to get past the 2-cycle intake port bypass inlet giving off pressure from the topside to the open crank area below.

Now I was in trouble again because any pressure generated on the topside was instantly relieved to the bottom. The ONLY way to get it moving again turned out to be the reinstallation of the base and flywheel Making it even heavier! This worked! Thinking that I could then extract the rod and piston, I opened it up again. No way! So I closed it all up once again and installed the flywheel.

This time I decided to roll it on through a full revolution. I never saw so damned much grease come out of one hole! Multi-colored at that.

It looked like a candy cane machine as the different colors of grease had blended into a striped pattern. This time the piston was completely loose and ready for extraction. I still had to deal with the bottom side ring ridge. After getting the rings stuck on the ridge, I drove the piston back in with a wood block.

And it was out! Amazingly, it looked to be in good shape. Lots of carbon, grime and remaining grease, but mechanically well. The top ring was loose, but the two others remained partially stuck in the grooves.

The casting of the block is a marvel to look at. You wonder how they were able to pack sand and accomplish the water cooling passages AND the intake and exhaust passages. I had the cylinder walls honed and new rings were custom made by the Niagara Piston Ring Works. A snap ring tool and sweat on the brow along with some feeler gauges to provide a ramp helped them slip to into their new home one by one onto the piston. When the piston reaches the bottom of its travel, the ports are uncovered, at which time the pressurized charge of new fuel and air is allowed to travel up and into the cylinder.

This exhaust is then piped on out where spent cooling water from the head is injected into the exhaust pipe, which keeps the exhaust pipe cool. During the up stroke of the piston, gasoline is mixed with air in the Schebler carburetor, which is drawn in through a brass intake valve photo installed within the throat of its connecting pipe.

A commutator photo sits atop the pump shaft to provide a switched impulse to the buzz coil at the appropriate time. Top dead center during starting and advanced during running. This engine can run in both directions, depending upon how the commutator is set and the experience of the operator in changing direction. Cooling water is picked up through a pipe from the bottom of the boat to a check valve at the inlet of the water pump photo.

It should be noted that cooling water will NOT be pumped in reverse due to the check valve AND the lack of incoming water in the exhaust line. This gear pump was made by a brass works in Syracuse, NY. You can mix oil with the fuel as with other 2 cycle engines, but a dual oiler is provided, one outlet for the ring area and the other feeds a slinger on the crank.

This slinger is ported to the rod bearing with a passageway inside the crank pin. Oil is not desirable in the base of this engine and therefore a blow-off cock is provided to drain the base while it is running.

So, here's where it sits now. Any day now Much later, work progresses on the project
