Re: Do i need to bolt my motor on?

Depends on where you keep the boat and if you want to leave it mounted.

I have an 18 on my 14' Starcraft and I have it locked to the knee brace for security AND if it should ever kick up the transom on a tight turn I will not have to dive overboard to find it.

It's really a personal preference but I would safety chain or cable it.

Nice boat! It looks like someone put some good work into rehabbing the interior.

With small boats and small motors, clamping usually works fine. It's only on the bigger motors that they get bolted to the transom. Using clamps is nice because you can take those smaller motors on and off to perform repairs, take to the repair shop, swap with a different motor, remove the motor so the boat fits in your garage, etc..

I also have a 14 footer. It came with a 9.9, then I upgraded to an 18 and now I have a 25 on her.

The smaller motors were equipped with a bracket for a safety chain and that's what I used.

The new one has holes in the brackets for mounting bolts. Once I found out that the position was right and performance OK, I drilled away....LOL.

Took 5 minutes....plated grade 8 bolts or SS. No problem. Can't come off now and I don't need the chain any more. Wing nuts on the inside so taking it off for service takes 1 extra minute.

Cost only a couple bucks. Peace of mind...priceless.

I remember as a kid wrestling with a running outboard motor in the back of my little boat! Anything above about 10 hp I would bolt on.

I use one of these on one of our boats even though it's bolted on. At least it won't loosen up and no one will steal it. About $24 bucks. The only negative is they tend to vibrate against the turn buckles, but I fixed that by pushing a few pieces of foam rubber in thru the sides of the locking bar.

Would insist on bolting it. at least for piece of mind and security

Have one jump off the transom sometime,-you'll bolt the next one on.[don't ask me how I know!]

the guy i bought it from didnt really maintain the boat other than jacking up the bow. the screw head broke off when i pulled on it. the blue decking is rotten and the bilge pump housing is cracked. all minor stuff.
i had a homeade stand for my 8hp xl shaft before this and the motor fits on it. with literally no room to spare and its not too big. its sitting in the garage as we speak too

Unless you store your boat in a garage, bolt it for security. One guy can carry that 25 hp, so it's a likely target for thieves. Aside from that, you get the security of not having to worry all the time about clamp screws loosening.

I have my 6hp bolted to my 12' aluminum boat. If it got stolen or fell off, I'd be off the water, and that won't do.

Re: Do i need to bolt my motor on?

The lock bar that Expedia posted is all you need if you leave that boat/motor outside. It also keeps the clamps from loosening and is cheap. I don't know what you are all doing wrong with your boat motors that you can't keep them on the transom. Don't scare the guy. I'm sure that you did have some motor mishaps, but those are pretty rare occurrences, not the norm.

The question was do you need to bolt it on? The short answer is no, it is not NEEDED. The full answer is that it depends on personal preference, where you store the boat, whether you plan to keep a lock on it, and whether or not you follow up on safety procedures before boating (such as verifying that the motor is securely attached prior to use).

Good luck.

The lock bar works fine, but it costs over $20. Four SS bolts (or two on my 6hp) and the washers and nylon insert nuts will cost about $5. I understand that some folks don't want to drill their transom, but...as long as you seal the bolts, it's no big deal. On an aluminum boat like mine, it doesn't even matter if you skip the sealing step.

It's just a matter of choices.

It depends on how you use the boat. Some people haul a 14 foot aluminum boat in the back of the pickup and attach the motor when they get to the lake. In that case, bolting and unbolting the motor would be a nuisance. If you trailer the boat with the motor attached, bolt it on.

Re: Do i need to bolt my motor on?

Years ago I saw a guy in a 16' fishing lodge boat with a brand new 35 hp Johnson come down off a plane and as he did this the motor rose up off the transom and sank. He tried to hang onto it by the tiller but was unable to and it pullled the fuel hose off the tank.

The motor had only been clamped on the transom as the lodge mechanic hadn't gotten around to bolting it on yet.

We tried scuba diving to find the motor but didn't have any luck.

I also had a friend drag his Yamaha 8 hp kicker by the fuel hose down a gravel road for a couple of hundred yards as it had bounced off it's bracket. Fortunately he had his window open and stopped when he heard a strange scraping sound.

I recommend bolting it on. :)

Regarding those lock bars... I had one on a 25hp. The p.o. had lost the keys so it had to be cut off. I did it with a dremel and a small cutting wheel in 15 minutes. now that I know where I should have been cutting, I bet I could have it off in less than 5min. Not as secure if your not close enough to hear the grinding noise.

If someone really wants to steal something they are going to. That lock or bolts is not going to stop a determined person. It just helps to keep people honest.

A determined thief can get anything. The object is to make it harder for him. Most people are not dligent in taking care of their stuff. So, given three boats in a row, and yours has the lock, the thief will go for the others.

Small price to pay for piece of mind.

Agreed. The manufacturers would not make these small outboards with a turn buckle clamp if they tended to pop off the transoms. That would be a quick class action suit for poor design. None of the boat rental places worry about clamping them on. You want a 25hp or a 5 hp. They just clamp one on the your rental boat and off you go.

The 99 25 hp 2 stroke I use that locking bar on was bought originally for protection for a Merc 9.9 from being swiped off another rig I owned. So when my Daughter picked up this 25 hp O/B I put that locking bar on first thing. More for protection cause small O/B's are prime targets for thieves. This O/B actually has two bottom bolts going through the transom too.

I know this because I have to raise it up 2-3 inches and that's going to put those upper clamp circles right at the top edge of the transom. I'll make an aluminum or plastic block to raise it up, but I'll definitely drill two new holes because that top clamp will be so high towards the top of the transom it makes me nervous just to have to take it for a test ride without the bolts back on.

It's only the first hole that hurts :D Start with a small drill bit and first drill a pilot hole. Spend $10 and go to home depot and buy a new bit the size of the final hole you will need. Go to West Marine and pick up 2-4 stainless steel bolts, washers and those brass lock nuts. These can be probably found in Home Depot too, a lot cheaper than West.

So bottom line, drill the holes for safety and buy that locking bar for theft prevention. A $35 total outlay is cheap insurance than having to spring someday for a missing outboard either stolen or sitting on the lake floor :eek: Or you could pay a dealer $90 an hour to mount it properly for you!
