Re: tilt trim installation
Hi
Found these on ebay- new and not cheap- and maybe not exactly what you need, there again, maybe it is, especially if you buy a used system with a dud pump!

Those work within limits. The metal is softer than original, the seals are of lower quality, and the tolerances are not as tight. The lifespan of the VB is short to start with and will shorten quickly as the horsepower increases. I would not even consider it for any engine with a 25" shaft or with 120HP or higher because it might not even finish the first season. On a 150HP 25" shaft engine it might not even finish the first day. In my highly biased and opinionated opinion, I would put the spot at 85-90HP. Above that go oem. below that go cheap. At 85HP take your pick. Chinese is cheap and convenient while oem lasts a lot longer. I would guess the cheap valve body should go 3-5 years on a 85HP.
If you look closely you will see that Force valve bodies used two different type of check valves. The early design used retaining clips to hold the check valves in place. The later design used threaded check valves that screwed in with an allen key. When you look at aftermarket valve bodies look for the retaining clip design. The version with allen key is cheaply made and will not hold up on a big engine. The version with retaining clips is more expensive but can handle engines over 60HP.
If you need a cheap fix then search the forum for a thread about using lawnmower carb kits to fix your check valves. Just do the check valves and don't take anything else apart. Even with the corner cutting it will be a higher quality machine with a longer lifespan (than the cheap new ones).
