This Marine Engine Project Page is being

 produced by the program participants

and is not complete  at this time.

 The page design and content are provided by the participants and this page  is an

 ongoing  seasonal project.

Three Phase  Marine  Project

The Project - Overview

The basic concept of this project is for the student to determine, during the disassembly process, the reason this engine would not run.  Then to make the necessary repairs, so that the engine might be placed back into service in a vessel. The second phase involves the participant becoming familiar with the Power Point program so that he may complete a Power Point Presentation of the entire project. The third phase requires that the participant become familiar enough with web page design, so as to complete his own web page using the Power Point Presentation and the  HTML language.

Meet the Crew
 

This crew is made up of one High School teacher and three candidates from the Providence area. 

Is it possible for a person who lives in this country to not know how a typical  propulsion system in our motor vehicles or  vessels operate? 

The Project - Phase I

The basic concept of this project is for the student to determine, during the disassembly process, the reason this engine would not run.  Then to make the necessary repairs, so that the engine might be placed back into service in a vessel.

Day One of the Project

Before disassembly commenced a compression test was conducted, and the  group noted that this four cylinder engine had no compression in two cylinders, Number 1 and 4,  and good compression in cylinders 2 and 3.

So,  we thought there might be a problem with the valves or, possibly holes in the pistons of cylinders 1 and 4.

After the valve rocker cover was removed we noted that all valves and pushrods appeared to be operating properly.

At this time the group was introduced to the basic principals of the internal combustion engine.  The group learned that gasoline and air is mixed in the carburetor, and how this mixture is introduced into the combustion chamber,  and how a spark from the ignition system caused the compressed mixture to detonate. The complete cycle of intake, compression, power, and exhaust was covered.

Second Engine Project  - Overview

First we tried to take off the gas tank, but we found out that we need to take off the seat. We took the seat off by taking the pin off because we didn’t have the key that opens the seat. After taking the seat off we took off the gas tank. Next we took off the carburetors, one on each side, afterwards we took off the battery. After we tried to taking off the motor. We took off the exhaust pipes that are connecting to the motor.

THE SECOND ENGINE PROJECT 

Before starting this project we knew that it was going to be hard because it was very rusty and not in very good shape. We started off by trying to simply remove the engine from the bike but it didn’t go as planned because we first had to remove the seat before removing anything from the bike. With our plan back on track we removed the seat by unscrewing two screws and taking out a big pin from the left side of the bike. After removing the seat we then had to remove the battery from the bike in order to get control of the screws in the middle of the bike. The battery was taken out by unscrewing two screws that were on either sides of the case in which the battery was put into be held in place. Also we removed the fuses.  

 

We figured out that in order to be able to remove the engine that we had to remove the tailpipes from both sides because they were obstructing the way to the engine after this removing the tailpipes we took out a big pin that was holding the engine and the bikes frame together. The engine has two screws on the left side that we got off but there still was a nut that has to be removed. Also on the left side is where we really have the problem because there are two screws that can be unscrewed but a nut will not come loose because maybe the thread of the screw is run and without first removing a part of the left side on the engine we can not remove the screws on the right side because they end a little before the left sides part of the engine. This is where we currently are at the end of day one of this new project.

Meet the Project Director

The Project Director,  a High School student with a couple of years of experience in our Summer Sailing Program, is pictured in the blue shirt. The Project Director is the charge person for this group at the group level. He ensures that there is continuity among the group members and that various tasks are carried out in an orderly fashion.

Meet the Director
 

This is the fellow in the grey hair trying to stick his finger into the engine.  Jim  is our Director and has been for over twenty years

The workshop

The workshop is an integral part of all SAIL USA programs, in that it is used to support the repair and maintenance of our program activities.

Day Two of the Project

This paragraph created by "Flash", and the group

The first step of day two was to remove the alternator, which keeps the battery charged by producing alternating current which is converted to direct current.

 After removing the alternator, we then had to remove the water pump which pumps circulating  cooling liquid throughout  the engine, we did this in order to get to the timing chain. After the water pump was taken off, we took the module, more commonly known as the "brain", and all wires connected to the module off of the engine.  The module is a solid state voltage regulator.  The last

step of day two was draining the oil pan, so we could take off

 the cover and  have access to the crank shaft.
