That did it. Thanks for confirming it with me.
I should have paid better attention when it came apart which side the rack was on. Now time to tighten up rudder then re-install all zip ties. Next I'm waiting on strut to be returned so I can get it lined up and re-installed. Then alignment. Then I'm about done except for stereo and upholstery. |

It looks like you might be *too* good at following instructions!
I would guess that the instructions assumed that the tiller arm would be installed on the opposite side, for whatever reason. It would seem to me that reversing the rack would solve it. You may want someone more familiar with the R&P systems to chime in though (like Jody). |

That's what I was afraid of. The only thing I can think of is that I put the helm in upside down so the rack is on the wrong side of it. But I feel confident the helm was put in right....with the gears that mesh to the rack facing up and the rack laying across the helm "on top."

Thanks for the further explaination. Yes, I agree with Tim. It's a assembly problem at the helm. The rack is on the wrong side of the pinion.

It is pretty easy to put the cable through the rack the wrong way on mine. I would start there at the wheel and work back if that does not work.

I dont think you can physically hook it up backwards at the rudder end, due to the exhaust hose. I would say the problem lies in the installation of the rack... something is reversed- either the cable or the rack itself.

Dude, whats the issue here? Is the steering reversed, or is it simply not centered?

New cable, new helm. Dropped rudder. Put back together, but apparently not well. I thought I put things back roughly in center...
now what do you suggest to fix this? |

David,
What was removed from the steering system? If the tiller arm was off, did you put it back on with the rudder and helm roughly in the center neutral positions? Was the cable removed from the clamp at the aft end? |

How come when I crank the steering wheel to the port side my rudder looks like this?
what could I have installed wrong? |

Measuring from the holes it's obviously bent. I can't figure it out...have not hit anything and there doesn't seem to be stress to the strut or to the hull.
I'm hoping my neighbor can take it to the machine shop where he works and straighten it tomorrow. If not, I may be rigging something like Chris's bottle jacks. Eric, one solid bushing. I guess I'll still replace with two. |

Dude, its probably bent based on your measurements, but Ive found that the base castings to be very rough sometimes, which makes the method you used to measure the straightness misleading. Ill try and dig up the pictures I posted of the method I used... but basically if you can measure off the bolt holes instead of the edge of the base, youre probably a little more accurate. 1/2" off probably means its bent though.

bent shaft? I'm sure this is not the correct way to determine whether it's bent, but there's enough difference that it seems pretty obvious. Table is level.
Can the strut be straightened or do I just have to buy a new one? also, do I need to make images smaller so you don't have to scroll sideways? |

ooops. Well the shaft is all the way to the port side of the brass shaft log. In fact there is some scoring on the shaft from it. So it's definitely nowhere near the middle. When it's in a "happy" position it is all the way against the edge of the shaft log (picture doesn't quite show that because I didn't get completely on top of it).
So next step is removing strut? Then seeing if I can have it straightened (assuming it's bent--which even to naked eye it looks that way). |

Dude, it sounds like you missed one important detail. The "shaft log" is the brass piece that is glassed to the hull. It sounds like you are comparing to the "shaft log hose" which may be introducing some error to your judging of centered-ness. Ideally, the hose is removed so that you can accurately see how close to the center of the log the shaft wants to be. If your shaft is indeed skewed over to the side of the log, then your strut is either mounted slightly crooked, or bent. |

starting to think my strut may be out of alignment. How would I know for sure?
I've got all the stuff on the shaft loose except the tranny coupler. I read this from Pete in another post:
The shaft is "happy" way over to one side of the shaft log. I'm wondering if it could have just "learned" that position in the rubber log or if it's that out of line? Dude out. |

+1. It's like popping out a ball joint. Tighten the ball joint press, grab a beer. BLAM! Pops off like magic by itself. |

When I first took the prop off our 88 after about 7 years of ownership it was remarkably easy. I was rather worried it was going to be a bear so I met "gotwake" at his kid's football game to borrow his puller, borrowed a 12" crescent wrench, blocks of wood and a big needle nose pliers. All we needed was the pliers to get the cotter pin out. The nut and prop came off by hand! The temperature was probably about 35 F. The boat did run smooth before this. |

Got it. Got a long nut (instead of castle nut) that kept the puller lined up. A pop with the hammer like TRB and Hollywood said. Gonna pull shaft and replace strut bearings. Do alignment (according to Eric's epic post) when it comes back together.
put the castle nut on for safety like you said, but prop came off really slowly. Pretty sure it's never been off before. Pete, I looked at that "lap" thread yesterday. It's outstanding. Thanks. It's good being back on here and chatting with you guys again. I haven't done much to the boat the past two years and got away from the practice of being on here. my list for the next couple weeks: -steering cable and helm -strut bearings -alignment -re pack rudder and shaft -impeller -tstat -belt set -new stereo -new upholstery on 3 seats (christines ordered today) -fix drip at strainer that rusted one motor mount I thought the prop would be the easiest. I hope it's not. It's finally over 50 again after 3 cold days! |

I've never not gotten a prop off with the C-style either. Snug it up and let it sit. I like to come back a couple minutes later and tigten it up. A tap with the hammer just may knock it loose. If not, move the puller between another blade and repeat. Not being in the boat repair business you have time to leave it on there and let it do its thing. Work smarter not harder.

As much as Id like one of those 3-bolt pullers, my C-clamp puller has removed ALOT of props. The ones that are really stuck will require a hammer. Put some tension on the prop with the puller, then using a small block of wood, hit the hub of the prop. Re-tighten puller and hit with hammer as many times as it takes... it will eventually pop.
Im usually swapping props on a lift in the water, so I dont have the advantage of heat... but I bet it would be advantageous to do so. |

Don't know if it will work on a prop, but an old mechanics trick for getting ball joints loose was to hit it from 2 sides simultaneously with hammers. The shock would loosen the locking-taper fit. Maybe try that when the puller tension is on. Reiterate saftey - have the castle nut still on!

David,
This is a classic case where a "C" clamp style prop puller doesn't work and the reason I actually made my own puller. When the prop is really stuck to the taper, the "C" clamp will stretch and then not pull with equal force around the prop hub. The style I made are available but are up there in cost and the reason I played around and made mine. Your best bet at this point is to make the style I have, buy one or find a 3 arm gear puller. Try heating the prop and cooling it a couple times before using the puller. When the time comes to put the prop back on, take a look at this tread if you haven't seen it already. |
