Weld stern bracket to fix shallow water drive? NS25C3

[tohatsu9.9guy]

I have a Nissan NS25C3, and made a dumb mistake. I loaned it and my boat to my buddies to take duck hunting, assuming that they'd take as good of care of it as I do, and it came back with a bent prop and a piece broken off the stern bracket that guides the adjuster deal into shallow water drive. Now, shallow water drive won't work just by trying to push the trim adjuster thing down after lifting then lowering the motor as it used to. I have to actually reach in and push the adjuster in with my hand to get it into shallow water drive, which is dangerous for my hand. I looked, and the piece (notch/groove on the stern bracket) that the adjuster catches when you push it down that guides it down to the final resting spot for shallow water drive has the tip broken off of it on one side, so shallow water drive no longer catches. I'm assuming that the stern bracket is made of aluminum. My question is: Could the broken spot be welded to build it back up, then ground back into shape so that the shallow water drive functions correctly again? I believe that the stern bracket is obsolete for this engine (what's new with nissan/tohatsu?), and I have a NS30A? in the garage which I tried to swap out transom brackets on, but they were ever so slightly different, just enough that they wouldn't work with my next model newer NS25C3 (again, typical for nissan/tohatsu). Any help or repair ideas would be great. Thanks in advance.

If it were my mint cond engine, I would tell my buddies. You owe me a prop and stern bracket...it's your problem not having taken the security measures while boating on shallow waters allegedly at speed. Too bad if they get pissed. The only way I would lend my boat/engine combo to somebody would be with me along.

A friend of mine nearly ripped his transom offf, he run into a near submerged door, what the hell is a door doing in the ocean ? while at speed with engine at locked position. I usually go boating at a unlock position while at speed, just in case....

Happy Boating

Re: Weld stern bracket to fix shallow water drive? NS25C3

what makes you think the parts are obsolete? I think the M25C3 model is still a current production model (just not sold in the USA any longer). If you google that model number you'll find a lot of Tohatsu distributor websites in other countries that list it as a current model. If that's the case, then replacement parts shouldn't be a problem here in the USA either. You might want to call your local dealer and see if they can get you the part you need.

I'll try to post pics when I get the chance. Yes, they are going to pay to fix it, don't worry about that. I've already made them aware. Also, I refuse to loan it to anybody anymore. Yes, I don't know why you'd ever have your engine locked except for when in reverse. I never lock mine. I believe by the direction the prop is bent, the damage to the prop and shallow drive happened in one strike of something underwater while in reverse. Prop is bent in toward the boat on a couple of blades, and the way the bracket is broken would've been hard to do in forward. I have searched for the parts, and the stern bracket for the C2 and C3 are listed as the same part #, but from my experience from trying to swap brackets from my parts motor to my good motor, the brackets are different. I'll look again, but I'm pretty sure that's the case. The parts have been superseded to a different number, which again looks to be the same part throughout the models. I'd hate to buy something then have it not fit.

Strange the damaged was done while at reverse, when reverse, the throttle is very limited, you just can throttle much less that 1/2 grip. Owners manuals recommends boaters to run in the locked position, inexperienced boaters will probably freak out while throttling at reverse and see tail coming out of the water. Other that this is good to run at a unlocked position specially if liking speeding or using a long shaft, you never know what hidden underwater or floating objects you may encounter while boating.

Happy Boating

**ADDED PHOTOS AND INFO** Thanks for the Part #'s. 1/2 throttle will get the boat moving plenty fast to cause damage if it strikes an underwater object. Yea, I agree. I even reverse unlocked bc unless you give it lots of throttle, the prop won't come up enough to cavitate. Here in Arkansas, there aren't many places to boat that you can be certain you won't hit something underwater. Lots of shallow rivers, lakes, etc with cypress knees, rocks, or the bottom just waiting to show your outboard who's boss. I'll get the parts ordered, thanks all for you input. I'll still post pics, I took some yesterday evening. **ADDED PHOTOS AND INFO-note differences in brackets between parts diagram and actual bracket on this motor. Many differences exist, such as shape of notches/grooves on inside of bracket where the tilt adjuster moves to adjust tilt, also notice recessed place for bracket bolt head and non recessed place for bracket bolt nut are on opposite brackets from that shown in diagram. When I attempted to swap the brackets with NS30A3 brackets, which I believe are the same brackets as the part #'s above, these were the problems I ran into. The damage to my bracket can be seen in the picture of my right stern bracket** I read that some parts may vary based on serial # for some engine models?
