The PSS Shaft Seal is the number one selling marine mechanical seal
worldwide and is installed as standard equipment by many of the worlds most
reputable boat builders / yards. The PSS Shaft Seal is also recognized as
the premiere retrofit (aftermarket) seal on the world market. Certified by
Bureau Veritas, ABS & Rina: Boat builders / yards recognize the advantages
and value of installing the PSS as it eliminates the maintenance, constant
adjustment & cost associated with traditional packing type glands. Aside
from these benefits, the PSS Shaft Seal helps to eliminate water in the
bilge (100% water tight) & wear to the propeller shaft. The PSS Shaft Seal
can be easily retrofitted and is available for shafts ranging from 3/4"
(20mm) to 6" (150mm).

The PSS Shaft Seal is a mechanical face seal that is created between
the flat surfaces of the rotating stainless steel rotor and the stationary
carbon flange. The stationary carbon flange is attached to the vessels stern tube with hose clamps and the carbon flange is attached to the front side of the bellows with hose clamps. The stainless steel rotor is fit on the shaft
in front of the carbon flange. The stainless steel rotor is used to compress the bellows before the collar is secured to the shaft with set-screws. This
compression (pre-load) maintains contact between the faces and allows the
PSS to compensate for the thrust from the propeller. The carbon flange is
bored larger than the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration problems. The
stainless steel collar is sealed to the shaft by two o-rings that are
recessed into the bore of the collar. These o-rings rotate with the shaft
and stainless steel rotor and do not experience wear during operation.


**As with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration.
PYI suggests as preventative maintenance that the PSS bellow be replaced in
six year intervals. During bellows replacement it is recommended the o-rings & set screws in the stainless steel rotor also be replaced."

Bellows may need to be more frequently inspected in an environment where
non-sealed batteries emit sulfuric acid. Sulfuric acid vapor will accelerate rubber deterioration, as will an ozonater.

The Maintenance Kit includes the items you need to properly maintain your
PSS Shaft Seal. Included in the kit is one (1) PSS bellow, two (2) O-rings,
five (5) set screws, four (4) new hose clamps and an allen key.

Books like this are why I get self-help books on Amazon
Format: Paperback
If you're looking at reviews for this book then you're likely looking for some insight into the college process on a deeper level than surface-level advice. In that case, you should undoubtedly get this book. I'm going to college next year, and I'm the type of person who copes with things by reading about them. Books like this book are the reason I do that. It's clear and easy to read, it's direct, it's straightforward, and best of all, it's full of simple advice that can dramatically improve one's college experience. It provides this advice without being pretentious- the book's title turned me off at first, and while the author certainly has a very pragmatic approach to college life, he decries resume-padding and the like. I've recommended it to many of my classmates, and it will serve as a sort of bible for me next year. As much as it's helpful on a practical level, it's helped me in another way, too. I went looking for books because I was nervous about next year. This book helped reassure me by encouraging me to focus on the exciting aspects rather than the unnerving ones. If only I could get such a powerful effect every time I spent ten dollars. A few years later: This review actually was written by my then high-school-age son, and I have to tell you that he went on to have an absolutely stellar, meaningful career at an Ivy League college. During those four years, and since, he has frequently referenced this book, and its author, whose other books he later read, as having been his primary source of guidance about how to handle his undergraduate life.

PROFOUND
Format: Paperback
Mesmerizing, profound, even for a study machine such as myself. Cal Newport, a college student himself, wrote these books after interviewing extraordinary students around the country who had straight A's, full social lives, and did lots of extracurriculars such as starting businesses & non-profits, and being politically involved. The point of all his books is how to study more efficiently so you can be an outstanding student while fitting in other essential dimensions of the college experience such as friends, parties and guest lectures. And unlike "speed reading," his techniques are not smoke and mirrors; they are solid and make sense. I didn't feel there was much overlap between his books. "How to Win at College" is composed of 75 two-page "tips" that cover a very wide range of topics. This is the book I originally fell in love with and ordered copies of for many friends, and I recommend reading it first. His second book, "How to Become a Straight A Student," focuses on a few key skills: the trap of "pseudo-studying," time management, how to actually study, conquer exams, and write papers. However once I read it, I liked it almost better than the first one! In short, they are both indespensible, easy reads, hard to put down, and completely different from any other "study skills" books you might read. They are basically "myth busters" of conventional wisdom about school success. If you want to know the "secrets of the universe" regarding succeeding in and loving college, look no further.

70% practical advice, 15% feel-good advice, 1% useless advice, 14% advice that saved my academic life
Format: Paperback
To be honest, if I had just graduated high school and someone gave me this book as a gift, I would roll my eyes and never open it. I picked it up a week ago, however, now that I am almost done with my second year of university, and I really do wish that I had had it (and cared to read it) two years ago. The book is seventy-five pieces of advice, each with about two pages of explanation. The advice is pretty simple, as you can see from looking at the table of contents ("Dress Nicely for Class," "Never Nap," "Eat Healthy," "Always Go to Class"). But the reason this book is effective is that it serves as a quick-reference manifesto for some of the more important (to me) advice. For example, I'm taking a grad-level fiction writing class. No due dates (except the final deadline at the end of the semester) and no class. You just write at your own pace and turn in a portfolio. This is incredibly difficult for me to do, and I'm unbelievably far behind in the work for the class. I was really quite worried about how I would ever pull it off. The whole semester, my fiction work has been priority #75, and I usually crash between priorities #14 and #20. But with some of the advice in this book ("Keep a Work Progress Journal," "Set Arbitrary Deadlines," "Avoid Daily To-Do Lists," "Don't Take Breaks Between Classes"), I actually feel pretty confident about being able to finish on time. By reading this book (and [...] and Newport's more recent book, ) I've adopted some strategies and habits that have actually yielded results. Before Cal Newport, I was up late every night, angrily doing my homework until I couldn't drink any more tea, without any free time. Now, I'm getting my homework done before sundown (for the most part), feeling enormously more relaxed, and regaining a good amount of the excitement that I had about college before I got here. If you're on your way to college, and you're the sort of person who can stomach (and listen to) advice, do yourself a favor and read this book. Newport admits in the introduction that not every piece of advice will be for you (for me: "Exercise Five Days a Week" and "Use a Filing Cabinet"). If you want to be more than an average student without being a "grind," this book has a good deal of solid advice. If you're already in college, and you're looking for more in-depth and practical advice, I recommend also reading . It has more thorough advice for confronting the terrors that you have come to know in college.

Will Help You Reach the Goal You Thought You Could Never Achieve
Format: Paperback
Quick review: if you're about to go into college, BUY THIS. If you're already in college, STILL BUY THIS. This great book has conventional and unconventional advice. I'm already a fan of Cal Newport's advice and blog, but this book condenses his ideas that are most relevant to me (since I will be going to college in the fall of '15). It isn't a typical 'how to do well in college' book whatsoever. This truly gives you the truth of what needs to happen to become a part of the exceptional. And he isn't writing it with the assumed purpose of impressing everybody or becoming a mega-successful overlord; he writes with the tone that leaves up the ultimate goals you have up to you. Also, the writing style is not annoying like a lot of books are. Personally, I just want to optimize my college experience, leave my comfort zone, and get into grad school. This book will help me. If you want to start the track of becoming a super-rich, art-gallery-going, Bentley-driving, awe-inspiring successful person, this book will still be very worth your time. It's absolutely worth the money if that's what is keeping you on the edge of buying this. It has countless (actually 75) useful ideas throughout, too, if you worry it has only one or two pieces of useful advice and that's it. Bonus: if you like what you read, he has a blog with even more stuff to learn.

Fantastic Advice
Format: Paperback
I'm a senior in high school preparing for my freshman year. This book is amazing. The advice is down to earth and believable without being preachy or perfect. Newport is perfectly willing to admit that things aren't always going to go exactly as planned, but still tells his readers how to accomplish great things. I absolutely loved the advice. Some of the advice in this book is not for everyone - APPLY TO TEN SCHOLARSHIPS A YEAR can be overwhelming and unnecessary, depending on the student. That said, it's easy to see how even applying a handful of these tips would change my college career for the better. As a student who will have to balance work, class, and a social life, I think this will be rewarding. Here are a handful of my favorite tips: CREATE A SUNDAY RITUAL STUDY IN FIFTY MINUTE CHUNKS USE THREE DAYS TO WRITE A PAPER EAT HEALTHY VOLUNTEER QUIETLY And the list goes on. I will definitely pack this with me in the fall.
