I have a new Suzuki long shaft outboard and it is mounted to the Catalina 25 factory bracket. while running downwind in moderate swells 2-3 feet the prop is often out of the water. Any suggestions as to how to get the prop lower in the water and still be able to see it out of the water when raised? Thanks for any help.

You're facing the classic problem of transom-mounted outboards on a sailboat.

Extra-long shaft outboards (25") are recommended for sailboats used in waters with much swell or wave action. I realize this is probably not what you wanted to hear if you have just purchased a long-shaft (20") model.

You can get a longer-travel mount (like the Garelick Offshore) that might help, but putting the motor down far enough to prevent prop ventilation will also put the powerhead at risk from submersion due to wave action.

Note that even the XL shafts can have problems in a 'nasty' sea.

I found some what of an improvment to that problem by adding the bolt on fins they sell for outboards motors. Seems to me that the water above the fins need to be pushed out of the way for the motor to "come out of the water" and thus adds a small measure of stability. Not a cure but a small help. Bought mine used in a marine consignment shop for ten dollars, some times I also see them on ebay....good luck.

It is too bad that you were not counselled to get the 25" shaft. People speak of 20" shafts being ok for some places but I sail on an inland lake and we have to have 25" and still have a lot of trouble with following swells. Can you buy the extension for your OB?

When I replaced my old 2 stroke with a new Yamaha 9.9 XL (25") I also moved the mount to the starboard side to help balance the port list. When remounting I attached the mount at the depth I felt I would be using most often in the middle adjustment position. Now if I really have a big following sea I can push the motor down to the lower adjustment and really bury the prop. I haven't the motor swamped yet.

Ed: I don't have a C-25 yet, I'm still shopping. A friend of ours mentioned the list, or leaning of C-25s, on a phone call last week. He said that a C-25 in our C-22 fleet had this anomaly. Do all of the C-25s have this characteristic, or is it only certain years, or keels? How much lean is it? Does one side of the boat get uglier at the water line than the other side? Can anything be done to minimize the list, like not having too much water or fuel in the tanks? I think that a noticeable list could drive me crazy.

When you measure a motor to check the shaft length, do you measure from the top of the motor block to the center of the prop, or to the horizontal plate above it, to get the 20 or 25 inch dimension?

Thanks, Aldo

Of the 4 C25's at my marina (all pre-1981 models, 3 with port mounted outboards and one with an inboard), none have the port list.

Maybe he needs to fill his water tank, and install a second battery...

I like the thought of installing a second battery , how about a holding tank also !

But seriously prior to my wife and I owning our Catalina 25, we owned and sailed/raced our Catalina 22 for 9 years. We were always told that the Catalinas sailed most efficiently at a 15 degree heel.We find that with our 25 also that especially on light air days, we get the boat heeled and we MOVE as compared to just Sitting there. Yesterday though we sailed in winds 20-25 with double reefed main and storm jib.. since the temperature was a balmy 48 degrees,we had made up Hot Chocolate with a touch of Baileys Irish Cream. We sailed for 6 hours and watched the sunset and than it was time to put Leprechaun to the dock. Alan & Eileen

Aldo, Sorry to have taken so long to get back to you. My C25 is a dinett model, we have added a propane stove/oven, we have pots and pans, canned food, and whatever winds up in the lazarett all on the port side, plus the closet behind the port-a-potty! Yahoo lists to port even with a full water tank and both batteries on the starboard side. I have moved every possible thing that I can to the starboard side and can just barely maintain an even keel. Of course I am in full cruise mode. On our recent trip to the San Juan Islands in Washington state, our water line was above the boot line. And yes there was a line from the water on the jell coat.

To measure the shaft length of your outboard, hook your tape on the cavitation plate above the prop and measure to the base of the power head.
