I went with a welded piston from Surplus Center (1.5x4x.75 DA piston) with 3/4"cross tubes. Since the pins on the engine were 5/8" and 1/2" , I ordered some Oillite brass bushings in 3/4" x 5/8" and 3/4" x 1/2" that matched the width of the cross tubes. The hydraulic fittings Were also available at the same place. The top fitting which worked out well was a 3/8"NPT x 1/4"NPT streeter ell. The bottom was immediately reduced to 1/8"NPT with a streeter ell from there to achieve clearance away from the yolk. All the hydraulic lines were 1/4" NPT fittings.
NOTE: I think a 2"x4" x1" cylinder was available with side facing fittings for more money. And if you can find 1/8" hoses that will be more than big enough to provide adequate fluid xfer to the cylinder. The small bennet tab pump I used would have been fine if a slightly larger diameter cylinder was available. The trim up only works at no-wake speed. I think a 2-1/2" cylinder with 4" travel and side fittings would have worked better in this application. Also be aware that you only have 1-3/8" width for the top cylinder mount. The top tube on my cylinder was 3/4" ID x 1-1/4" and fit perfect, a larger tube ID i.e 1" may fit with some grinding you have to check these clearances out thoroughly.
Finding the correct equipment for this application takes a lot of time and patience as no one seems to have the ideal set up available for a reasonable price. Good luck ... PM me if you need a copy of that schematic that is in the video.
