Hello all,
It looks like this forum is going to be a wealth of information for me. Thanks to all.
I picked up my (new to me) 1980 C25 yesterday here in Oregon. I knew it had a Honda 8 hp 4 stroke w/little use (25 hrs.), but was amazed at the extra long shaft. Is this the correct motor for the C25?
Do most of you that trailer your boat have the motor mounted on the bracket while you are trailering your boat?
Last question: Any idea what tongue weight should be with a tandem axle Trail=Rite trailer? Usually 10%?
Thanks,
Mike

"Is this the correct motor for the C25"

The 8hp Honda XL shaft is an excellent choice.

"Do most of you that trailer your boat have the motor mounted on the bracket "

I don't trailer with my engine on... but I know folks who do. I think most will secure some additional supports from the motor bracket to the transom pushpit bases. (stern rail)

>"Any idea what tongue weight should be with a tandem axle Trail=Rite trailer? Usually 10%?"

10% is a commonly used 'rule of thumb' for trailer tongue weight... That will put about 600 lbs on the hitch. With a 'long' trailer like the C25 you might get by with a bit less. The 'fitment' of the C25 to the trailer will usually be established by the factory.

A 25-foot sailboat with the engine hanging nother foot off the transom can raise and lower that motor a lot when it pitches in seas (or wakes). The longer the shaft, the better--even if it means you need to tip it up a little with the bracket up to get the skeg and prop out of the water.

Enjoy your Cat and the forums, and join the association... It's priceless for all of us.

I have a Honda 9.9 4 stroke which I leave on my boat when trailering however I would not if it were not for the fact that the 30 miles to my house is smooth and flat. I tie a line to the lifting handle to ensure it cannot disengage and drop the mount down while on the road. I would NOT do this without a 4 spring Garhauer mount.

Welcome to the forum Mike.

When I trailer any distance, I take my Honda 9.9 off the transom. I put my OB and rudder in the back of the pickup, as I think it best to have as much weight as possible in the tow vehicle.

There is a lot of very good information in the Technical Tips section. A very good strategy for getting the best possible answer to your specific questions is to have pictures of your boat.

This forum has been of great on-going value.

I just sold my 1990 8hp honda xl shaft because of weight (approx 103 lbs) and the fact that I can't stand dragging a motor around when on a port tack (mounted to starb'd side of rudder). The drag actually pulls the helm to starb'd. If you race, it presents a problem particularly if you take it off and place it over the keel down below. I think that the power was overkill since hull speed is hull speed. I stepped down to a 4hp 20" which is about 24" to the center of the prop and weighs in at 57 lbs. I am on Lake Erie and run under sail power from dock to dock whenever possible.

Postscript> Val thanks for comments. I ordered a 25" nissan 6hp today. I still saved 50lbs.

Hi Scott,

I understand where you are coming from but I'm concerned with how you would plan to return to your dock in the event of a dismasting,or a sail wrap. Do you measure the 24 " length from the prop center to the top of the motor mount?

I used a new 6 H.P. 20" shaft on my C-25 in Great South Bay and traded it in for the extralong shaft 9.9 motor. At the time I had to transit the Patchogue river and the 6 hp just didn't cut it. It would eat air in the slightest wake or swell, and the coasties frowned on sailing among all the commercial traffic there.

I have a "regular" long shaft 8hp O/B. One time I had to be towed back from the race course after the wind picked up to 35+ and there were 3'-4" waves on the lake. The O/B was spending 50% of the time out of the water.
The extra long shaft is obviously preferable.
