  • The Sternmaster ME-186 Sterndrive/Outdrive Installation Cart is what we came up with after being asked by technician's to build a different style device for removing and installing lower units.

  • When outboard motors of any size need servicing, this heavy duty engine stand offers the ideal solution. The mounting surface simulates a transom, both in angle and thickness, keeping the outboard naturally oriented while you work. The uprights are angled toward each other on either side of the engine to maximize accessibility. Four heavy duty locking casters allow for easy movement as well as additional stability. This stand can also double as a display in your show room and at trade shows or for storage. Fits all standard bolt-on outboard motors, generally up to 300/350 hp.

    Be sure to check out our battery tray accessory (ME-110-01) which has an innovative design allowing it to sit freely in the front of the stand.

  • Outboard Test Tank, ME-OMTT
    The Outboard Motor Test Tank can be used with the ME-110 Large Outboard Stand or the ME-140 Small Outboard Stand. It can be converted into a conventional test tank by installing a wood transom into the interior brackets...

  • The ME-OMTT is designed to be a great asset for easier testing of outboards. In order to eliminate the need to constantly pick up and move outboards from stand to test tank and back, our tank is designed so the legs of the ME-140 or ME-110 follow channels under the test tank. To use, rotate the motor up into the lock position, roll the stand into the test tank brackets and pin them into place, then rotate the outboard back down into the run position while on the stand. As an example, we have tested a 15 hp motor full throttle in the forward position. You can see that test on You Tube. Larger outboards may not be able to run at full throttle in this tank. Our test tank and stands are designed to work together so that while an outboard is mounted on the stand it never needs to be removed throughout maintenance and testing, saving time and contributing to safety.

    The test tank is able to be picked up with a fork truck, while full of water, and moved wherever you need. The entire unit is hot dip galvanized for greater protection from different environments. The test tank comes with a drain plug, 2 rubber coated brackets, and 2 pins with wire locks.

    We have also designed the test tank so that you may, if you wish, add a 34" long 2"x8" board into channels welded inside in order to use the tank without having one of our stands.

  • Pontoon / Tritoon Dollies, ME-350
    The Newly Redesigned ME-350 Pontoon/Tritoon Dolly features rubber coated 18" long adjustable bunks allowing it to be used for several different shaped pontoons or a standard hull boat....

  • Our updated Pontoon/Tritoon Dolly design is great for displaying and storing pontoons as well as solving the problem of unloading a tritoon off of a scissor style/center lift trailer. The interchangeable dual height brackets are secured with 2 bolts each and can be switched from tall to short in order to work when offloading a tritoon (tall) or a regular pontoon (short) given the significant height difference between the two when on a scissor style/center lift trailer due to the axles. See the images below for a visual explanation.

    Both sides of the dual height bracket were designed to fit round, elliptical, and v-shaped pontoons or various standard boat hulls with an innovative adjustable support system. No tools are needed to adjust between the angles, making the change easy and convenient while allowing the dollies to be used for many purposes. Unlike other dollies, this specific design keeps the bunks situated between the strakes instead of hitting them. The longer than average 18" bunks create a more stable surface by spreading the load over a larger area of pontoon to help prevent denting. In addition, our bunks are dipped in a durable rubber coating creating a smooth surface for your pontoons to rest on. Our rubber coating is ideal because it will last longer and stay smoother than the carpet covered bunks used by other companies.

    The adjustable design and rubber coated bunks make the ME-350 a versatile and very sturdy dolly. The low, wide “v” shape of the frame allows the pontoon to stay as low to the floor as possible, making it easy to board the boat while creating a stable base. The hard synthetic 5” casters are both durable and heavy duty. During the design process aesthetics were a priority. The black powder coated frame and casters are attractive yet will not detract attention from the pontoon, instead blending into the floor.
