Well, I bit another bullet today and ordered a new Nissan 9.8 with 25" shaft and electric start, to be delivered after Christmas.

Gave up on trying to make the 20" shaft Suzuki work. Still having trouble with the electric start, even after replacing the starter solenoid. Realized also that even if I do get it to work, it will still be too short with the new motor mount. So, I'll tinker with it over the winter and sell it on craigslist later.
Good news is our daughter gets in from school tonight, so she'll be with us for the holidays.

How much does the OB weigh?

My daughter gets home soon too.

Old guys with boats and daughters who love their Papas, what great bunch of people we turned out to be.

Motor weighs 88 lbs. It's a 1982 Suzuki, 9.9 hp 2 cycle, with electric start and 20" shaft, that came with the boat when we bought her last fall. The shaft length was fine with the original motor mount, but is a little bit shallow with the new mount I installed a few months ago. The motor runs just fine and will start if I hotwire it, so I know the starter works. I spent over $400 on it this summer, and of course, they say everything was working when i picked it up. Could be the start switch or the neutral switch, or maybe I'm just doing something wrong. Anyway, it's at home now on a stand. I've got a 5hp 4 stroke Merc long shaft from our C-22 on the boat temporarily.

If you are asking about the weight of the new one, I don't know yet. It should be about 91-95 lbs, based on the ad. I bought it through outboardsonline.com, a company in Cookeville, TN, about 120 miles from us here in Nashville. Incidentally, they offer free shipping within the 48 states and a discount to Association members. Details are in the members only section. Being in TN I do get charged TN sales tax. still, the price was good.

I got the Tohatsu 9.8 XXL electric start from On Line Outboards and love it.

Totally trouble free. Make sure the idle speed is set slow or it won't shift easily.

You will virtually NEVER pop the prop out of the water ever again, even with the motor mount on the "high" setting!

Much better MPG too, maybe due to getting the prop in deeper.

Without going into a long story. My Nissan9.8 extra long shaft went into the salt water. Retrieved
it. Sailed home to port, docked and cleaned out the "moisture". She started on the 5th crank. Gotta love the Nissan. Even with the extra long shaft in large swells I've had the prop come out of the water. Ive had min for about 8 years or so. Still runs like a top. I think you'll be glad you bought a Nissan.

Glad to hear good tidings about Nissan/Tohatsu. A large swell on our lake is 1.5 to 2 feet, so I shouldn't have much trouble with the prop coming out of the water. Merry Christmas and Happy Holidays to all.

My Honda 9.9 pull start weighs 102LBs. I'd like to move up to an electric start - but at same time would like a lighter OB. I'm checking to see if that's possible.

I love my Honda - has been totally reliable and am inclined to stay with Honda. However, I've been driving Nissan vehicles for 20 years and have been impressed with their performance.

It's my understanding that the Nissan/Tohatsu outboard motors are the lightest-weight motors you can buy for the horsepower. The 9.8 electric start is supposed to be right at 91 lbs, the extra long shaft will likely add 4-5 lbs. They told me the package will weigh about 100 lbs, and they do not ship on a pallet. hope that helps.

Hate to burst your bubble, but I've "popped the prop (of my Tohatsu 9.8 UL) out of the water" more than a few times in choppy lake Erie. Only happens with big chop with wave intervals really close together and from different directions.

Admittedly, it may have more to do with my limited experience than with the motor, though.

Lake Erie is well known as the roughest waters north of Cape Horn.

Other than that my XXL shaft motor stays in the water under almost all conditions.

Of course I am usually sailing the boat - if we have waves that steep we have the wind to go with it.

David,

You're going to love that motor on your 25'. I bought the 2007 from the same retailer in 2006. My sailing is done on Narragansett Bay and with the motor mount lowered all the way, the cavitation plate does not come out of the water. You're also going to love the new technology: as that motor will have 9.8 horses off the prop! It will weigh in at 95#(give or take an ounce) and arrive in a large box, packed in styrofoam. The only advice I can give is connect the hose to the motor before priming the bulb. It will then start on the first pull or push of the button(which you gotta love). Oh, and its great on gas! Good luck and happy sailing!

Dave P, I've had mine since '05 and find it an excellent motor for the C-25. A little bitchy tilting it but that's probably my age related problem.

Hurray!! Our new Nissan 9.8 arrived today, presumably safely (haven't opened the box yet). Hope to start setting it up this weekend. Box is huge! Takes up almost all of the space in my minivan. Should have expected that. Had to detach the middle bench and push it all the way up next to the front seat backs.
Any suggestions on best choice for the 2 types of oil?
Edit: I checked and it came with gear lube in the lower unit, so that part is already done. I decided to use Penzoil 10W-40 as the engine oil.
That should work okay. One interesting note, one of the 4 connecting bolts for the lower unit was loose. Nothing in the manual about it so I got it tightened snug.

Dustysailz,
Do you run the motor dry if you are going to be gone a week or more?

Dave, each time I use it I allow it to run dry. Just disconnect the hose and let her run. I think you're going to be real happy with that motor.

Thanks, I certainly hope so. I've heard several people say to run it dry. Didn't have time to take it out to the boat today, and we have the possibility of snow flurries Jan. 1, so I don't know when I'll get it installed on the boat. One side of me wants to get it on and play with it, while the other side says keep it in the garage til spring!

We had a little warming trend today, up to about 55, so I decided to check out the new baby from Nissan. I set up the stand at the end of the garage, set the lower unit in a clean trash can with about 20 gallons of water, hooked up the fuel line, connected the electrical leads to a starter battery, held my breath, and pushed the start button. What a sweet sound! It started immediately on the first push of the button. And you can barely hear it at idle. This is going to be nice, really nice. Thanks to all of you on this forum who recommended the Nissan/Tohatsu motors. Mama is happy, too, and we all know what that means.
The real proof in the pudding will be on the boat. I have a feeling, though, that I'm going to have to enlarge the hole in the transom for the electrical leads. These are bigger that the ones on the older o/b, and they just barely went through.

Dave P,

You're right the box was hugh, and in mine in '05 there was a bottle of oil sent by Tohatsu. I made the mistake of throwing the bottle out after using its contents. It was an 800 cc bottle and it would have made subsequent oil changes easier to have a bottle of the right capacity. Hate it when I overfill and have to syphon off "X" number of cc's until it is just right.

Your reaction to the hummmm of the four stroke is as was mine. The next surprise will be when you see how little fuel it uses. It's a gem.

Best of luck with it.

PS, I only run it dry at the end of the season. I also use it every day and see no reason to run it dry only to fire it up the next day.

I didn't see a bottle of oil in mine. Will it be a problem to have overfilled the oil. I poured in the whole quart (about 946cc), which it took without even reaching the threads at the fill opening. The stick says it is above full. Should I take some out?

Okay, I've drained about 4 oz. out of the crankcase, and the stick reads right at full. That should do it. The motor stand I made for the garage holds 2 ob/s. I added wheels at one end today to make it easier to move around, and to give it a bit more height for the 25" shaft length.
Also, I took the 4 hp off the C-22 and put it on the stand next to the new 9.8. Wow, what a difference when you see them side-by-side.
Incidentally, the ultra long shaft Nissan is actually closer to 27" from transom to cavitation plate.

Did you throw all the packaging out already? If not I'd go through it and look for black plastic bottle resembling the Castrol quart size bottle.

There were some folks that had problems with the Tohatsu/Nissan motors that could possibly have been caused by overfilling. Best to be right on the stick mark.

I've still got the carton and all of the packing material. To my wife's dismay, I tend to keep original packing materials for a while. Given the size of the box, it's still in the back of my van. It's going into the storage shed tonight. I'll check aroung for the oil bottle. It would be good to keep. 800ml = 13.53 oz.
As indicated above, I did empty out about 4 oz. of the oil. Tried getting it out of the dipstick hole, but that was a real pain. Put a paper cup under the drain plug and opened it up. Glad the motor was still in the garage, that would have been tricky on the water.

Edit: Checked carton, it's empty, no oil bottle.

I took the Suzuki 9.9 in one last time (different shop) to try and get the starting problem resolved so I can put it up for sale. I had replaced the starter solenoid and it still would not start. The answer was very interesting, and there was only a small labor charge. On these motors, the clearance tolerances are very tight. When i replaced the solenoid, the positive contact comes extremely close to the engine block to which the solenoid is mounted. A hole had been worn in the rubber cap covering the contact and it was touching a small burr on the block, shorting the circuitry. They moved the solenoid, tilting it very slightly and put some extra tape on the contact cover. And they say it now starts just fine. All I hope to get from the sale is most, if not all, of the recent repair money. We'll see.
