GOING ELECTRIC PART 12: Installing the mounts

Now that the stringers have been cut to to the prop shaft angle. Now we need to install the brackets to the stringer bed. There are made up of heavy gauge aluminum as shown below:


First we make sure that they fit and will provide the proper base for the motor mounts.


The next step was to provide a level base on the stringers. Epoxy was thickened and applied to the cut stringers. This will seal the open grain and provide for a solid flat surface for the aluminum angle brackets to lay on.

If you look closely at the above picture the thickened epoxy has been laid on the stringers. Some plastic wrap has been applied over it. The aluminum angle bracket has been laid on top of this plastic. This allows the aluminum bracket to be made level without sticking to the still wet epoxy. The metal bar laying on top of the stringer will be used to make sure the bracket is level. After this step the epoxy will be allowed to cure. The plastic will be removed the aluminum brackets secured to the stringers with bolts. Then the motor mounts will be attached to the aluminum brackets and then the brackets that will hold the motor are attached to the motor mounts as shown below:

If you look closely at the prop shaft in comparison with the previous pictures you will notice the prop shaft has also been cut down by about 9 inches. In the above photo you can see that the shaft face is flush while the previous photo shows the original shaft with the key way groove. The next step is to mount the motor.

The first lift of the engine

The transmission was finally removed from the engine. I had spent most of the morning on the transmission but, things were about to move along. It was now time to do the big lift of the engine. In happier times I referred to the Westerbeke 27 as the "iron jenny" when it reliably started and allowed the boat to motor when the wind dropped. But, after a year of looking at it, dealing with mechanics scratching their heads at $75.00 per hour and more. I know refer to it now as the "iron pig" as it continued eat dollars from my wallet and prevented me from leaving the mooring all season.


So there it sat for over twenty years in the same place. With it's business end wide open like a mouth just daring me to come near. One slip up and I might have a crushed hand or 424 pounds of engine crashing down on the hull. In the back of my mind I'm thinking if there is an accident and I get my hand or arm caught between the hull and the engine would anybody be able to hear my crys for help. NOTE : Keep the cell phone handy.

The first thing to do was remove all the nuts to the bolts that held the motor mounts to the engine stringers. I had had conflicting information on how the bolts on the brackets that the engines mounts were sitting on were made. So I would need to find this out. I also removed the nuts and bolts that went through the side of the engine stringers that held the "L" brackets in place. Once this was done it was time to to lift the engine. I first took the two 18 inch pieces of chain and wrap them around the two arms sticking out from the engine and where the motor mounts attached. These chains were then attached to the hoist. As shown in the photo below:

Below is another shot showing both points of the lift.


I now lifted this end of the engine enough so I could then see how the angle brackets and bolts would come off of the engine stringers. They actually turned out be nothing but two bolts screwed or spot welded into the metal brackets and they just lifted off the stringers. There was however a hole cut into the stringers to accommodate the head of the bolts that would have prevented the bracket from just sliding forward. If I had attempted to just slide the engine forward I would have done a lot of damage to the stringers. One of the "L" brackets is shown in the photo below: With new confidence that I could lift the engine by myself. It was now time to turn to the other end of the engine and do the same there. But, I would not be able to duplicate what I had just done in the confined space of the engine compartment. It would require a different approach.
