Extremely well made

I am giving this 4 stars because it fills a need I had, and the build quality is great, but are a few changes I would've made if I were to have designed it for my motor specifically. I have a 2000 Johnson 25 J25TESSD. The tiller handle is extremely close to the hand crank even with the top jack mount in the lowest mounting hole (max spacing between tiller and crank). If I had realized this interference I would have mounted my plate a bit lower on the transom, and then clamped the motor a bit higher on the engine side plate. Holes were already drilled in the boat though, thankfully it does still operate OK. The motor is just a bit higher than I wanted to even with the jack retracted all the way. Now the crank hitting the transom in the lowest position is my lower limit, cav plate just above bottom of hull. The tight spacing between tiller and jack crank makes using it on the fly almost impossible, and completely unsafe because when the crank handle is vertical it blocks the tiller from steering. I have found I am generally not using it while moving that much, mostly idling through shallow areas. My stock prop is unable to "grip" the water at anything less than fully down, so expect to modify your prop (heavy cupping) or buy a stainless cupped propeller. You wont just put this on and do what the videos show. I bought a new cupped stainless prop, but have not gotten it on the water yet. This gets me through sections on the Saint Croix that would be totally impassable otherwise. Current is too swift for rowing or a trolling motor, and this section is no wake anyways, so its serving me well so far regardless of these issues.

Worth every penny! I used their hardware kit and spacers to save me time. It was super easy to install and it works flawlessly. I maximized my engine height and got about 8 inches out of it which was needed because I’m running a long shaft jet pump engine.
