Would a 8 or 9.9 hp outboard be to much for my cat 22 I hade a 4hp and it was not quite enough to bring her home in rough sea's

Michael, I have a Tohatsu 6 hp 4 stroke with the long shaft for my Catalina 22. It performs very well, it moves me along at a good speed of about five knots (GPS reading). I have the long shaft for the chopy water conditions of the S.F.Bay. The Tohatsu comes in 4,5,and 6 Hp the only difference between the three is the spark plug coil. One point of interest is the some 4 stroke motors have a thermostat that can become frozen closed when used in salt water. I have found that the spark plug should be replaced every season. I have found that my motor is easy to start, it can be laid on the handle side for transportation. The best part is there is no mixing of fuel and oil. I believe that the Mercury, Nissan, and the Tohatsu are all made by the same company. I have had good exeriences with my Tohatsu. I hope this helps. Fair winds AL

Response to kicker.
Michael, If you are in rough water and cannot sail, for a 22ft boat, if four H.P. engine is not enough, then a an eight horse is overkill for hull-speed. Your bottom may be dirty or the engine is not tuned. A 'standard' bracket should take the weight of a 9.9, but this is overkill. If you do go heavier, put larger backing plates and washers for the through-bolts mounting your outboard bracket.

Tohatsu = Nissan
Al, Not sure on the Merc, but tohatsu and Nissan are definately exactly the same. Good advice on the six h.p. tohatsu long-shaft. Terry

8hp on H22
On my H22 with a full keel I run a Mariner 8hp long shaft. It pushes it well through any sea conditions I have faced.

I use a 4 stroke Johnson with 25" shaft and 4 blade working prop. Have busy water in the bay here, sometimes with 3' chop, and our inlet is an adventure in best conditions. My boat is an h25 two tonner. This motor is a barge pusher. Hope this helps, Regards, Jim.

Not overkill
I use a 9.9hp 2-stroke on a Mac22 and in rough conditions am sometimes glad its there. Its certainly not 'overkill', esp. because you can't talk about hull speed when fighting strong adverse wind, current and wave conditions. From all the discussions on this size boat, the consensus seems to be around six to eight hp.

Weight is a consideration.
I agree that a 4HP outboard sounds a little light for a boat probably displacing in the neighborhood of 2,800 pounds but before deciding to replace the engine I would insure that you are getting the rated power. Check that the motor has the correct prop size and pitch to allow it to attain the RPM range for the rated horsepower. I run a 5 hp on a 21 feet daysailer and also use it on an 8 ft Zodiac as a tender to a larger boat. The engine will propel the 1,300 pound sailer beyond hull speed but will not get the 75 pound Zodiac on plane as it will not rev up to its maximum power. The prop's pitch is not adequate for the inflatable.

When I worked for the Catalina dealership, most of the 22s went out the door w/ either 7.5 or 9.9 2-strokes. While you may be able to easily reach hull speed with a smaller engine, it's nice to have the extra horsepower. Especially usefull when the stern's pitching in and out of waves, or when maneuvering in close quarters requires an emergency change in momentum. As long as the motor mount is rated for it, You should be fine with up to 10 HP. Just make sure the mount's installed with good backing plates.
