hey guys found out why the tilt was not going up. here the cable had come off the gear switch. anyways got it going up and :eek:oil came flying out the side of my tilt cylinder!! nice blow out crack about an inch long. what would cause this as it was working fine before. is one tilt cylinder enuff for a day on the lake or should i shell out 200 bucks on a used one and have to drive 2 hours to get it and waste my day one the lake? thanks!!

Re: tilt cylinder blowout!!

Since the shift cable was disconnected, my guess is it's a one drive and has the reverse lockout on the shift plate. If the reverse lock is in the wrong position, you will blow the cylinder out. Don't ask how I know that.

Re: tilt cylinder blowout!!

The reason you are so frustrated is because you don't understand what you are working on. If you don't understand what you are working on, you will screw something up. So you might as well download the OEM manual and start reading. I'm sure it will cut down on your frustration level.

Re: tilt cylinder blowout!!

You haven't had enough time to read and UNDERSTAND the system, how it works and why it works the way it does.
Without the reverse lock, when you put the drive in reverse to stop. The drive will come up out of the water.
newer systems have check valves in the pump itself instead of the reverse lockout.
You can get those pumps for about 700 bucks if you want one. I'm sure iboats sells them.

Re: tilt cylinder blowout!!

look at you reverse lock, there are markings on it for adjustment.
Here's how I figured out if it was the reverse lock causing inoperation.

disconnect your lower shift cable and your cable from the control.
you should now be able to move the arm that the reverse lock pivots on easily.
on mine I could feel a place where it seemed to have different resistance against force applied.
this was my engage/disengage point in the reverse lock, subtle but noticeable.

move to "one side" of this point and try the trim both ways. does it work both up and down? if it doesn't rotate the arm back the other way and past the resistance point.
now try the trim again up and down again...did this fix the problem?

that's what the marks are for, reverse locks can be adjusted.

my trim does not go up in neutral...it strains the pump and stops after a few inches...but once it is in either forward or reverse, both directions work great and that's the only time I'm adjusting trim is under way so when I get back to the dock I drift up on trailer, kill engine, shift into forward and raise trim for trailer.

it's a work around until I can adjust the reverse lock properly but I got so tired of messing with it I just deal with it this way as the boat trims normal under way and my drive doesn't lift up when in reverse.

hope this helps.
