I am purchasing a new motor for an O'Day 23 and am considering a 9.8 four stroke Nissan extra long shaft. This will be used for coastal cruising in MS. Do I need extra long or will long do? I have a motor bracket that raises and lowers the motor. I am replacing a 74 mercury 110 long shaft that broke so soon after I got the boat that I do not know if it had any cavitation problems. I have a partner in the boat who is not yet comfortable sailing and may be motoring quite a bit. I had originally thought an 8hp long shaft two stroke would suffice. Most of the dealers I talk to advocate four strokes, but allot of boaters are skeptical of any thing but two strokes. My partner wants a new as opposed to used motor. Any Ideas on this

I had the 9.8 Xtra Long
With the prop so deep in the water, it was one of the smoothest and quietest 2cyl 2 strokes I ever owned. I wish I still had it and the boat it was attached to. Sold them both a year ago. I remember my last trip where I motored for 20 miles on about 1.5 gallons. (no wind) At first I though I was going to have to use the second 3 gal tank. But it was never needed. I would buy the 9.8 again in a heartbeat. And the XL never came out of the water.

Four stroke
I have a 9.9 Yamaha 4 stroke,long shaft, electric start on my S2 7.3 (24 ft). This motor was on the boat when I purchased it used four years ago. It runs very quietly and smoothly and gets good mileage on regular gas. Previously, I had a manual start Evinrude 9.9 2 stroke on my Venture 25. As to how long the shaft should be, the answer depends on the boat. On my S2, the cavitation plate is about 3 inches below the water (Yamaha recommenda at least 2 inches) and it has not been a problem. On the Venture, the cavitation plate was 2 inches below the water and it ran fine, except in heavy chop. The boat would "hobby-horse" through the chop and the motor would come out of the water, rev high, then plunge back into the water. I am not sure that an inch or two of more depth would have made any difference on the Venture. The 4 stroke is great from the standpoint of not having to mix oil with the gas, but it is so much heavier than a 2 stroke, that it can be a problem. First, the outboard bracket for a 2 stroke is usually smaller and ligher, with smaller springs to lift it than the same for a 4 stroke. Make sure you current bracket is adequate. Next, I am unable to lift my Yamaha up on the bracket, even with the heavy springs. The best I can do is tilt it out of the water. On full tilt, the motor comes all of the way out, with about 2 inches of clearance between the motor's foot and the water. Have your new motor trial mounted then try lifting and tilting it to see the clearances. On electric vs manual start, the electric does a good job, as long as you have a good battery and your cables are not too long. I have had to manually start the motor when the battery went dead. This requires removing the motor cover (and on the Yamaha, an inner cover over the flywheel), wrapping the emergency start rope around the starting sheave on the flywheel and giving it a good steady pull. If the only problem is the dead battery, the motor starts right up. By the way, the motor is a 1989 model and has never been rebuilt (only routine maintenance). I have no idea how many hours it has on it, but I would guess less than 1500. Runs great!

4 Stroke Extra Long
For quiet, power, and pollution, go 4 stroke. Go extra long shaft just for the few days when the water is rough and you don't want to cavitate. It can save you. Good point on making sure the motor bracket is strong enough to lift the weight of a 4 stroke. With all the 4 strokes on the market now, there are a lot of brackets that will. Get electric start and an alternator if possible. Really makes a difference when you can charge a battery.

Only half of the Equation
The motor shaft length is only half of the equation. A long shaft will put the prop deep in the water, but the bracket which raises and lowers the motor may not raise the prop out of the water. In many ways the amount of movement of the bracket is more important than the shaft length. You need to look at the combination.

No sweat startaing the Nissan
I also have a 9.8 Nissan. Drives my overweight Aquarius 21 just fine. 4 stroke would be too heavy for the design of the boat. Would put the cockpit drains under water. The Nissan electric start also starts very easily (usually with one pull) on the rope (standard rewind type pull string)when desired. Good motor and if you can get the long shaft out of the water when you want it out/up then that's the way to go. BTW, have you'all recovered from Isodore yet ? Was down there with the Red Cross based in Biloxi right after and B.S.L. was on my hot meals dinner /supper route.

Thanks for the input
I decided on the 9.8 two stroke XL. I like the cleanliness of the four stroke but in all my research weight was a problem for people that pulled their motors up and down. I do not want to replace the motor bracket as well. Thanks to all for the input. Dave J, We were pretty much unhurt by Isadore as I am in New Orleans in an area that is considered high ground in a below sea level town. Thanks for asking and coming to the Bay's aide.

outboard for Oday 23
I had an Oday 23 for four years and found that a 8 hp outboard had plenty of power in any conditions. I had a 2 stroke Evinrude that was fine. Get the extra long shaft since the bracket on the boat is mounted pretty high. I also had the alternator which kept the battery charged.

FYI
FYI- The Nissan 9.8 four stroke XL shaft is $1925 shipped, and the two stroke XL is $1660, both are electric start with alternator shipped at http://www.porta-bote.com/nissan.htm. This was the least expensive I could find in case some one else is looking for a new kicker.

8HP Honda on my 23...
I have a new 4 stroke 8 HP Honda long-shaft on my ODay 23. Power is great for the boat, no problems lifting up/down or tilting, quiet, efficient and non-polluting. I think the 8 is plenty for the boat, but I'd only get a 4-stroke no matter what size you get.

No! What you need is a
Retractable motor mount! Buy the short shaft and you'll be able to pull it out of the water with motor mount! This is the best way to do it because it protects the motor! I would not get the 4 stroke. They are not all they are cracked up to be, they are not worth the money and too heavy! The oil is messy too! TWO STROKE IS THE ONLY WAY TO GO AND KEEP AWAY FROM HONDA!!!

FYI Update
Well the nissan 9.8 XL two stroke was back ordered till mid-october so I went back to my original two stroke 8 hp long shaft idea. $1245 shipped, here on thurs. A short shaft definately will not work on an O'Day 23. I tried a friends old johnson 9.9 short and the water covered the cavitation plate by only a quarter inch.

Sounds like a good choice
and a good price...what brand? 9+ seemed a bit much to me.. my smallest boat was a 25' and a 10hp Honda zipped it, a 4 hp evinrude worked for what I use a motor for. Now runnin a 9.8 Merc on a H27. Plenty of power too...but I like to sail so they all get worked on more than they get run. IJ
