  It is sucking way to much air.Lift is all the way down. Motor can be dropped a half inch or so but I would have to drill new holes in the lift itself. It is a new to us boat. Silver streak jet sled with a tunnel. Has a 90hp yammie. |

A set back with slots might be a sensible solution.

How long is your shaft?

Looks like it may be time for an extension kit. If you go too much
lower the way it is, the steering cable looks like it will be at an odd angle where it will have to make a sharp "jog" downward to get into the tilt tube. |

If you drop it more, you'll seriously limit the ability to tilt up for trailering. The power head and hardware out front crashes into the transom. Don't ask me how I know.

[/quoteIt has room even if I drop it as the lift goes up 8-10 in. Almost broke the cover on my zuk 140 that way. Good thing they have the limiter. |

Do jets run higher, or was the jet a 25 inch lower?

 Lowered it as much as the stock holes allowed.Real close to a three inch difference right now. It has a plastic piece that extends out about 4 inches that I can put on. It helps keep water to jet foot and spray. If I custom drill all four holes I can get it as close as 2.5 inch. Decisions Decisions |

Is that some form of screw jack inside the aluminum "jack plate".
If so, why not remove the jack screw and replace with something shorter? A fixed height rod with clevis ends? |

 Lift is a fixed height no adjustments with the electric motor. Cannot change the height of the lift.

I guess I don't understand how that jack plate is designed.
If you remove the part I have circled wouldn't that allow the motor to be lowered?

Motor ran a lot better. Only sucked air every so often. |

Can you just drill new holes and remount the jack plate/engine 3" lower?
Edit; A longer Teleflex steering cable for extra clearance cant be more than a buck fiddy. |

What I mean is to remove the electric actuator completely and replacing it
with a shorter solid rod with clevis's on each end. Of course it would be "fixed" with no adjustment but it should lower the motor. Sure would be nice to see it in person. ETA - Maybe cut the lower bracket and drill a new hole for the actuator pin?

Already has holes higher up from previous mounting. I know they can be welded shut but am trying to avoid that if I can. Welding here is over almost $200 an hour.

  I have a older cmc lift that I am comparing right now. May end up switching if I can figure it all out.

 Looks like I need the one on top with the step in the steering guide. Currently have my old 85 zuk arm and bolt on it. It dropped the arm enough to where it does not bind.  Another problem is steering is very hard from center to one way.Installed a new cable. Even with the old cable it was very stiff one way. Also had a lot of slop. The steering arm that connects the cable to the motor is put into a bind. |

Does it steer hard one way when it's on the trailer not running in the water?

Quote HistoryOriginally Posted By KB7DX: Does it steer hard one way when it's on the trailer not running in the water? When turning right -when the cable is being extended- is when it binds up. The end of the cable was being pulled up. This part was bent from the previous owners.  With the lift low and when they tilted the motor the part hit the boat and was bent up. You can see it in the very first pic. Motor turns very easy when unhooked. |
