Regarding a 1980 Catalina 25. I'm guessing the outboard bracket is the original. I have a 6hp Suzuki that is fine from dock to river (St. Johns River, NE Fl) but need a little more "umph" some days.
My question is, will that original bracket fall off if I put a 9.9 Yamaha on it?? I think it weighs 91lbs. I can get a great deal on one.

It shouldn't.

<blockquote id="quote">quote:<hr height="1" noshade id="quote">RECOMMENDED OUTBOARD ENGINE
An outboard engine of 7.5 to 10 horsepower should be adequate to propel the Catalina 25 at hull speed
under usual conditions.
A larger engine will not increase hull speed and may add additional unnecessary weight in the stern.
Long shaft engines are preferable; however, standard length shaft engines should be adequate for most
conditions.
OUTBOARD BRACKET
The factory installed outboard bracket is spring loaded to assist lifting and lowering the engine. It locks
in both the up and down position. To release the lock in either position a downward pressure is applied to
the red handle while lifting or lowering the engine. The motor should not be lifted clear of the water
while it is running.
When under sail, the motor should be kept in the raised position and tilted forward so that the propeller is
clear of the water to eliminate unnecessary drag.
The motor bracket manufacturer's recommended maximum horsepower should not be exceeded.<hr height="1" noshade id="quote"></blockquote id="quote">

While the pre-88 manual doesn't specifically say, it suggests a 7.5 to 10 so I'm sure you'd be OK.

I think the Catalina manual(s) are referring to lighter 2-stroke outboards.

The original bracket will hold the Yamaha - but you yourself will need more "umph" to raise the motor!

The Yamaha 9.9 (an excellent motor by the way) is a high thrust unit - putting even more stress on the bracket and transom. The transom on my 1981 C25 actually cracked - but I had the considerably heavier long shaft, electric start model.

Good luck!

I have an '84 with the original bracket and a 9.9 2-stroke, long shaft, electric start Johnson/Evinrude motor that weighs 90+ lbs, and the bracket and transom have held up for the past 26 years. It does take a little effort to raise the engine but, not that bad.

When we bought Recess, it had what I believe was the original mount with a 2-stroke 9.9 Suzuki long shaft electric start motor. The arms of the mount were bent slightly (cause unknown) and the PO had set up a block & tackle to the pushpit to aid in raising and lowering the motor. We ended up replacing the mount and the motor.

I believe some early C-25s had brackets from Fulton (instead of Garhauer). They had four flat aluminum bars in two closely set parallel pairs, like this:

...with a very narrow footprint on the transom. I would not mount a 4-stroke over 6 hp. on that bracket. The Garhauer, with stainless steel tubing for its structure, should be OK, although the early ones didn't have much spring power for today's heavier engines.

Related question...

Anyone ever have the hoist feel like it's just hard to muscle (apart from the weight issue)? When I hoist or lower the engine it seems that something is stuck and I have to push (or pull) the engine through that point.

I recently bought an '83 C25. I replaced the deteriorating wooden mounting pad for the engine with a homemade one - I epoxied together some plywood, filling in the gaps and holes, and epoxied over the outside, then painted for UV protection.

I fear that in remounting the new pad I may not have the holes drilled dead straight on, and the frame is a bit bent, causing the hoist to not operate smoothly. Any ideas on this?

Thanks,
Carlos

You need a bracket designed for four stroke motors, the springs on the original bracket are not strong enough to control the lowering and raising of the motor. I have installed a 9.9 four stroke Yamaha on the original CD bracket and had to replace it with a Garelick 71090 model which is not ideal given the limited (9") vertical travel, the 71091 model has a 15" vertical travel but is pricier.

I don't see how slightly crooked bolts for the mounting pad could impact the operation of the bracket arms. Perhaps the bracket was bent prior to your ownership?

What outboard engine are you using?

Then I'd blast 'er with WD-40 (with an oil boom around the transom of the boat, of course).

Re: stuck engine bracket...

I have an early 80's Evinrude 9.9 Yachtwin 2-banger. Maybe 75-85 lbs. No apparent wearing on any bushings or pivot points, and the bracket itself does not look especially aged or worn. It does not look like there is wayward bending, apart from the little jog that seems to be built in, like indicated by the arrows:

I have the exact same setup as you have. Same Evinrude 9.9 Yachtwin 2-banger. Same Garhauer bracket. On mine I too have to push down to engage in the down position and lift up with some effort to raise the engine. Looking at your picture it doesn't appear that anything is THAT bent. Perhaps some lubrication on the pivots might make it a little easier.

I replaced the original mount that carried the 9.9 Johnson with a Garelick 71090 mount. I mounted a 9.8 Tohatsu. The new mount is much better than the old mount and the small additional weight of the motor is handled easily. The mount has plenty of travel. I measured the travel and prop location on the old motor and mounted the new mount so the motor ended up in the same location. The mount actually has one more notch of travel and allows for the motor to be lowered deeper allowing me to go forward without the motor coming out of the water when I enter the marina by myself to get to the bow lines. Spend the extra funds and get the better mount. The mount works well and handles the new motor much better. Look on the web for the best price.
