I need to purchase a motor for my C25.

I am curious what your opinions are on the 20" vs the 25" shaft.

I would like to get a new Honda 9.9.
The 25"XL power stroke (4 blade prop) is about 400-700 more than the 20",depending on whether I get electric start or not.

I sail on Lake Tahoe only.

My last boat had a 5hp long shaft and when it got really rough it would come out, especially when I went to the mast to lower the main in heavy conditions.

I think you answered your own question.

I love my Tohatsu extral-long.

try the search function, there have been some very thorough discussions recently. general consensus is for 25" for most situations ., 20" for some more sheltered applications, 15" for desperation only HP: 8 -9.9 (mostly because 25 inch shaft electric start is more widely available in 9.9hp) 6hp ok for light duty

Hi John... Yes--get the longest shaft. But you can still save a few boat units... Pardon me repeating myself, but you should be aware that the Honda 8 is the same engine as the 9.9, except that, according to a Honda rep, the cam on the 9.9 is timed for more high-RPM horsepower and the 8 is timed for more low-end torque. You will never use the upper third of the RPM range on either engine, but torque is useful when horsing the boat around a dock. (I had the 8 on Long Island Sound, in some conditions as bad as you would want to imagine.) What's the difference--$350 or so?

The Tohatsu 9.8 is apparently a nice engine, less weight, and less expensive. The Hondas have a stronger alternator... But a more important criterion is service--make sure you're taken care of in the long run.

Make it up by going with the 8! You won't be sorry. Or go Tohatsu... but don't go 20".

I bought my 77 Catalina and it came with a brand new 5 horsepower Nissan 4 stroke engine - short shaft.
I have used the engine in moderate conditions and was surprised at how well it moved the boat. I think it should do on the small lakes we have here in Colorado but will invest in something stronger / with long shaft should I move on to larger bodies of water.

HI JOHNNY P.

EXTRA LONG SHAFT...I'VE HAD BOTH 20" AND 27" THE 20 INCH WON'T DO WHEN THINGS GET DIFFICULT. YOU'LL BE KICKING YOUR BUTT AND THE 20" OUTBOARD SHOULD YOU TRY TO CUT CORNERS FOR WHAT IS ESSENTIALLY THE PRICE OF A GOOD MEAL.

CAN I TELL YOU A STORY ??? O.K. I ADDED AN EXTENTION TO MY HOUSE AND WHEN IT CAME TO DECIDE WHETHER TO GO WITH A CRAWL SPACE OR A FULL BASEMENT FOR AN ADDITIONAL $10,000??? I WENT WITH THE CRAWL SPACE, BEING A LITTLE SHORT OF CASH AT THE TIME ( BUT THINGS IMPROVED )AND ...I'VE BEEN KICKING MY BUTT EVER SINCE. NUFF SAID.

Check out www.onlineoutboards.com. They are an advertiser on this website, too, and give a discount to C-25 Association members. The 9.8 Nissan (same as Tohatsu), 25" shaft, elec. start that I bought after Christmas was just barely over $2K after sales tax, which I had to pay because they are in TN and so am I. They were offering free shipping.

Sounds like CT has a use tax along with a sales tax, as does TN. If I had bought the o/b from an out of state vendor and had it shipped to me, I would be obligated to remit the use tax to TN, same rate as the sales tax. As you indicated, many such consumers don't, which is why the states would like to come up with some kind of system to tax interstate sales at the vendor level, and why they also want to tax internet sales.
However, since my vendor is in TN, it was an in-state sale and they were required to charge the tax.

After I bought my new Yahmaha 9.9 x long shaft my brother in law sowed me an electric motor. mounts uner the boat like an inboard has an alternator to charge the bat bank while sailing. I believe was a 15 hp for like 10-12 hours on 2 bateries if your interested I can find out where he saw it. And to top it off it was only $2,000.00

I would go with the long shaft (25"). That is what I did when I bought my 2006 9.9hp Honda. However, if you have a 2 stroke engiine right now, two things to consider: The 4 strokes weigh more except for the lighter weight outboards made by Tohatsu, etc. That and also going with a longer shaft may get you thinking about what then to do about the outboard motor bracket. The original brackets were spring sized for the lighter 2 stroke motors. Also, a longer shaft outboard will may have the prop in the water if you normally do not tilt your motor up when you leave for the day.

In my case (1989 Cat 25), I bought the 4 spring bracket from Catalina Direct and it had same hole pattern as my original bracket, so it was an easy install. I keep my boat in fresh water and like to keep the outbaord in the raised but non-tilt position when docked. I have no problems as my prop is mostly out of the water except for the bottom 3-4".

Not to pick nits, but to clarify... 25" (or 27.75" depending on how it's measured) is designated "extra long" or XL. Long is 20" (or 22.5"). On a 25' sailboat in any significant chop, you want the X.

My new Nissan (Tohatsu) 4 stroke 9.8 is only 3-4 lbs heavier than my old 2 stroke 9.9 Suzuki!

The mount is another example of what a great C25 I have. The PO installed a piston operated bracket with dual backing plates that is rated to 125 Lbs.
It works like raises and lowers like butter.

I wonder if anyone knows where to measure shaft length?
the boat came with a 97 Nissan 2 stroke that I cannot use, I have a feeling its an XL but am not sure.
Might help me lell it if it is.

The standard measurement is from the top of the inside of the clamps (top of mounting board) to the anticavitation (or antiventilation) plate--20" for long and 25" for extra-long. Honda "longs" measure 22.5" and XLs measure 27.75". I believe Tohatsu/Nissan is similar.
