SPECIFIC FITMENT: Our outboard steering locks fill fit 3/4 in. (19.05 mm), 25/32 in. (20 mm), and 7/8 in. (22.225 mm, NOTE: this size will fit very snug) hydraulic steering systems that utilize 4 inch rams. Compatible with Hydraulic Steering Brands include SeaStar, Protech, Silver Steer, and Uflex. NOT Compatible with Baystar, GoTech, and Vevor systems. Ensure each piston length is 4 in. when the outboard is centered for best fitment. Singular arm hydraulic systems are NOT compatible.

SUPERIOR SHOCK ABSORPTION: Using our Mangrove Products high compression rubber formula that we currently use on our transom savers for outboard motor and have now been integrated for your outboard engine steering stops to prevent violent sideways motion and impact of the outboard's steering system when trailering both short and long distances.

MATERIAL DIFFERENCE: Using Mangrove Products proprietary material mixtures of internal EPDM rubber and outer liner of ABS/Polycarbonate ensures rigidity, strength, shock absorption, and functionality. Our rubber wedge is hard enough to mitigate deformity of rubber and soft enough to absorb shock and energy when compared to metal or plastic

INNER LOCKING GROOVES: Our internal 10 groove design allows a true lock to shaft and to ensure correct placement to piston when shock occurs during trailering. Our special formulated groove system accommodates fitment to 3 different shaft diameters.

OUTBOARD STEERING SUPPORT: Our outboard steering locks provide optimal securement and shock absorbing qualities that prevent bending of clips that could potentially pop out of place. Our design ensures the locking steering stabilizer will stay secured and attached in the event of sudden impact when trailering your boat. Other versions have potential to bend or flex causing the support to pop out or deform.

EASY TO USE: Our outboard motor lock allows for simplistic placement to each of your 4 inch hydraulic steering rams. It is important to know that centering the outboard first, provides the easiest install process. Can be used with boats outboard hydraulic steering systems mounted to Yamaha, Suzuki, Mercury, Tohatsu and others.

EXTERNAL GRIP: Our textured grip design allows for an ergonomic feel that allows you to easily grab the steering stabilizer for placement and removal. The steering stabilizer is also small in size and can be placed in your dry box or hatches until its next use.

ENHANCED OUTER LINER: Our hybrid ABS/Polycarbonate outer liner supports rigidity and structural performance compared to others. Our outer liner also has a glow in the dark option for easier visibility during early morning and late night boat trailer launches at the ramp OR gloss black.

REDUCE OUTBOARD MOVEMENT: Using this improved system will keep your outboard motor steering cylinder centered during travel and will absorb the expected shock when trailering your boat. Our design allows movement to prevent seal damage while also preventing sideways motion of the outboard during travel.

More pros than cons, very convenient, but durability is an issue.
Size: 15 Combo Travel Size
Pros: I think that this is a good product. I've had it for several weeks and travel every week for work. It's a good design and the vacuum pump is ergonomic and reliable, in my experience. Charges relatively quickly at home and I'm not sure how long the charge lasts, because it's convenient with a USB-C port, so I charged whenever the charge got to 3 bars. My experience is that dress shirts maintain the pressing if folded and packed neatly. They're creased, but hang them in the hotel bathroom and the steam from a shower loosens the wrinkles nicely. Cons: durability. The bags are pretty thin and after 3 or 4 trips the seal in the bag(s) can become compromised. I suspect the leaks are tiny and in the actual bag vs. the seal. With regular use, this was in only two of the fifteen bags. The double zip lock is really durable. FOR CAMPING: they were great for motorcycle camping, however the durability became an issue. I was camping along a lake and took some care with the bags, but admittedly was a little harder on them than I could have been. I took extra bags just in case, and am glad I did. Three of the 6 bags I took slowly lost the vacuum. If you're using them for camping, pack extras. They're inexpensive enough to continue to buy replacements periodically and you do get a lot. TIPS: pack the vacuum in the suitcase with the bags. Pack the bags with a complete outfit for each day. The temptation is to pack shirts in one bag, socks/underwear in the other, etc. It's more difficult to repack dirty clothes that way, but if you have each day in its own bag you just use each one for a dirty laundry bag.

Absolutely Perfect?!!
Size: 15 Combo Travel Size, Size: 15 Combo Travel Size
AMAZING!! This made packing soooo easy and such a breeze!! My suitcase was organized & I had everything that I needed for my trip. It has a great suction & comes with several red strips (I’ll call them) to ensure a tight seal before suctioning the air out. The bags comes on several different sizes & hold quite a bit of items in the big bag which held out hoodies & sweatsuits. Vacuum it’s not loud at all. Lightweight but packs power. This is a game changer! Very durable & great quality!! I’d highly recommend this item.

Over packer approved! GOODBYE checked bag fees!!
Size: 9 Combo Travel Size
These were incredible for our recent flight to Tampa. I’m an overpacker by nature, and we normally have to check at least one bag, but these completely changed that. We were able to fit everything into our carry-ons and backpacks with room to spare, which even saved us from paying a checked bag fee. The vacuum came already charged, and I still haven’t needed to recharge it, which was a nice bonus. It also comes with a small travel bag to keep the charging cord together, which made it easy to stay organized. The suction is strong and works quickly. I packed one bag completely full and it compressed it down to about half the size. The bags are durable and easy to seal, even without using the plastic zipper clips. As long as they’re fully sealed, they stay compressed and don’t slowly let air back in. We unpacked everything at the hotel and stored the empty bags in our suitcases, then reused them to pack for the trip home with no issues. The vacuum isn’t silent, but it’s not overly loud either. I’d compare it to being quieter than a typical hair dryer. This is such a game changer for travel and saving space. I’ll definitely be using these for every trip.

Extremely well made travel vacuum bags
Size: 9 Combo Travel Size
These are great kits for Travel and storage. I now have two sets. The pump works very well. Small enough for carry on. One very small dislike, There are small clips that slide across the top closer. But nothing to stop them either end. So may fall off. But I would highly recommend them. 9 out of 10 for me.

Good Space Savings, but the Bag Zippers don't hold very well
Size: 15 Combo Travel Size
I purchased these Vacbird travel vacuum bags mainly to save space in carry-on luggage and cruise packing, and the overall concept works well. The included rechargeable air pump is compact and convenient for travel, and the compression bags can significantly reduce the amount of space taken up by clothing and soft items when sealed properly. The bags themselves are easy to fill and compress, and they can definitely help organize luggage more efficiently for longer trips. For bulky clothing like jackets, sweatshirts, or extra layers, the space savings are noticeable. The rechargeable pump is also more convenient than manually rolling air out of the bags repeatedly. The reason this isn’t a higher rating is the zipper closure quality. The zippers feel much weaker than they should for a product designed around repeated compression and travel handling. Several closures required extra care to avoid separating or leaking air, which reduces confidence in long-term durability. The system works, but the zipper design feels like the weak point and keeps the product from feeling as reliable as it otherwise could be.
