I don't remember what the official name for the part is and I don't have my manuals handy to look it up, but there's also a sping-loaded cog in the chain and that's what went out on my drive. Its a little smaller than a golf ball, has two symmetric aluminum castings and a spring. It was a long time ago that it broke and I haven't studied it lately, but I would assume its function is to either reduce the impact loads else give the motor some free play to wind up.

The problem is most likely either the tilt solenoid or in the motor itself. If you look in the archive I had an issue with my tilt a few months back and got a bunch of answers. My problem turned out to be that the tilt motor was shot internally. You could switch the wires around on the solenoids to see if the solenoid itself is the problem.

The drive unit power tilt always works going up, but is inconsistent when going down. When it doesn't work (occasional issue when lowering) flipping the Motor tile switch in the down position just results in a clicking sound. If I just keep trying....sometimes 10 - 15 attempts it will eventually work/lower the drive and then be fine until the next seemingly random failure. Any likely cause for this issue?....ex. some type of relay issue? Also, from what I can tell there is NO Hand Wheel on the tilt motor (maybe non-orig)...which is also very difficult to access (requires removal of step).

Justin, from the pics you recently sent of your Surfer, it looks like you may have made some modification of the to enable manual lifting and dropping of the Drive unit.....did I observe this correctly? If so, I'd be interested to know what you've done.

btw: Scott, I replaced the doel fin with a correctly placed Hydrofoil (Stingray XP II) and it's a huge improvement...thanks for the catch.

Best,
John

> One side of the diaphram on the fuel pump is exposed to fuel and the other side to atmosphere.? This allows a pressure differential to?develop as the dia phragm oscillates and results in fuel movement or pumping.? Without the vent, the pressure differential would be much lower (due to the added resistance) and the pump would be? less effective.? The vent is located on the top side of the diphragm housing, which is the wide round part of the fuel pump assembly.? On my unit there was a slotted, threaded, aluminum plug with a hole drilled in the middle.? This made it easy to pull the plug and put a hose fitting there instead.? Drill and tap the carb to add a similar fitting near the top of the carb and?connect the two with fuel line tubing.? When the diaphragm eventually ruptures and leaks fuel onto the vent side, the fuel will dump harmlessly into the carb instead of the bildge (obviously the boat won't run too well with a failed fuel pump so dumping the excess fuel into the c!
