| I'm hoping to get the inside width deminsions of stringers with aluminum (engine / trans) cradle and without on a 1986 to 1990 "2001 Nautique". I seem to have fitting / alignment problem with not enough adjustment from side to side at transmission mounts. Any Help would be appreciated. |

what is your exact model year? note that the 1990 will not be a 2001 as is changed hull that year. "2001" model last year was 1989...

What are you trying to accomplish- an alignment? Did you just put in new stringers? Otherwise, Im not sure how the inside stringer width will help you. That being said, all boats of that era will have aluminum engine cradles, though the 1989+ configuration is entirely different than the earlier 2001's. '89 was the first year CC went to the "tabbed" cradle, with wider (~26-27" inside to inside) stringers. I can tell you that the earlier (pre-1980) boats without cradles have stringers spaced at approx 20-21" inside. I would imagine a (cradled) 2001 would be spaced the same, but have not measured one. ------------- |

1982 - Stringer is 21 inches wood to wood. The fiberglass adds some thickness. Aluminum Cradle is 20 inches inside dimension, and 20.5 inches stringer to stringer. I just put a tape on the cradle, so I'm positive.

| 21" must be pretty common. My Supra is 21" stringer-to-stringer. Probably has more to do with the engine than the boat, I would guess. |

| I wasn't sure of exact year model ('88 or '89). I was pretty certain that within those year models ( except '90 ) had the same configuration. It required complete stringers, floor, and foam replacement. When all is completed, the tech claims that transmission mounts do not have enough room to adjust between aluminum cradle. All before and after measurements were within 1/4". The inside stringer measured 20 1/2" before and 20 1/4" after from side to side and "welded" cradle fits nice. We did not disturb the pylon receiver at hull. The stringer position at rear exhaust is same location. I have no idea ( many reference points ) why it wouldn't go right back to same position without any trouble. My inquiry was too see if there are many variations to measurements from manufacturer and tech did not catch the bottomed out adjustment when removed. I even considered different transmission and mounts being installed, but haven't gotten information regarding differences. Thanks |

Steve,
You seem to be good with the width but what about the new stringer dimensions to the center of the boat/shaft log? Could they be offset to one side? Did you do the stringer job? Who's this "tech" guy? Is he a mechanic? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I was out indexing the plugs on my 89 2001  And decided to put the tape across the stringers they are approx. 26.5" inside to inside. The 89 was the first year for the PCM 1.23 tranny and they have different mounts to previous years. Tim it does have a tabbed cradle.
JoeinNY knows all about the different mounts as he converted his 83 2001 to the new PCM tranny. ------------- If you're going through hell, keep going http://www.correctcraftfan.com/diaries/details.asp?ID=2999" rel="nofollow - 89 Ski <a href="http://www.correctcraftfan.com/diaries/details.asp?ID=5685" ta |

Mark, Do you use the spacers under the plugs or do you buy 10 sets of plugs and then mix/match like Tim does to dial in the position? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| The original stringer system was offset and made several inquiries. I was told to replace in same position. I wouldn't be able to install pylon in its original location to hull had I moved the front section of stringers in any direction and the rear is dictated by exhaust system. I have been in boat repair for 27 years and for myself for the last 15 yrs. In most cases with sterndrives, little adjustment, in any is required to align. I didn't remove this driveline and left to speculate what may have gone wrong. Tech has a pretty good reputation and I have known for years, but also has the ability to make most situations somebody elses fault, from bad design to irresponsible customers. I'm researching the possibilities. Thanks |

I know I'm not compairing apples to apples with respect to years but my Holman Moody book says "Stringers should be 22 1/2" on center, as is standard in the marine industry" ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Well, 21" stringer to stringer plus half the width of the stringer on each side is 22.5" so that makes sense. BKH ------------- Livin' the Dream |

I "think" 88 was the last year for duel exhaust and 89 was the only year for a 2001 to have a single exhaust, and std rotation eng, 1:23 trans. ------------- - waterdog - http://www.correctcraftfan.com/diaries/details.asp?ID=3896&sort=&pagenum=2&yrstart=1978&yrend=1978" rel="nofollow - 78 Ski Tique |

the trunions should move in and out to accomadate width, whatever it may be, if going form a Borg Warner or vica versa there should be no problem, did he change anything in the powertrain? the trunions are pinch type and face to face on the mounts should be well under the 21" mark...something is missing ------------- "the things you own will start to own you" |

Great datapoint Lewy- I assumed they didnt change up the entire stringer system until '90 with the new hull. I should have known better, as the dual to single exhaust change would have required a change anyways. I edited my post above for correctness. ------------- |

| I appreciate all The help ! This Nautique did have the dual exhaust which would make location of both set of stringers even more cridical, but does give a great reference point at rear at flappers. It would seem, with this many original manufacture reference points, should not be a problem. I'm interested in Lewy2001 comment on '89 with 26 1/2" stringers and PCM 1:23 w/ different mounts- curious as to mount style and if adjusted "All In" would be in 20" range ? If it is not a trans swap, then it would be a stringer system originally installed and already at no adjustment (offset). This was not noted when removed, so no modifications made to compensate. If this is the case, it will be a good lesson learned for anybody reading this post- always check for adjustibility. Doesn't matter if your working on sterndrive or inboard. Thanks again ! |

Steve,
Just how far off are you? Can material be removed from the mounds to gain the amount needed? We all forgot to welcome you to CCfan. Welcome!!! Have you been around for awhile? Is this one of your customers boats? Is it in our diaries? If not, get some pictures and some text to Keith so he can post it in the dairies. Tell us more about the boat. We love stringer stories!! I've got to ask about the stringer job - Doug fir and epoxy resin or did the customer opt for the cheap route? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Yes it would- the front mounts are the same on the newer boats, the rears are shorter. Width is unchanged. The wider-stringered boats have cradles that have alumium tabs that extend inward that the motor mounts sit on. I dont think any of this helps you! ------------- |

| You would be hard pressed to install a stringer so far out that the mounts cannot be adjusted.In fact it would be extremely visible to the naked eye and conflict with areas like the mufflers and the header board.I think theres something else going on like a rusted adjuster or a mechanic that doesn't understand the four point mounts. |

AMS,
I got your email but your address was private on your profile so I could not respond directly.. anyway.. I am unsure of what your transmission is but the width of the mounts did not change between the different cradle configurations. The widths here are all about right, if the holes in your cradle are approx 22.5 apart center to center and the stringers are centered correctly you should have plenty of adjustment. I think it is more likely that your strut is not straight or that the front of the motor needs to be moved over a but than you are out of adjustment space on the tranny width. However, imho you could mill down the face of the brackets where they interface with the transmission a good 1/8 to 3/16 of an inch, and probably more on the opposite face if you had to. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1477 - 1983 Ski Nautique 2001 1967 Mustang 302 "Decoy" http://www.youtube.com/watch?v=cO5MkcBXBBs - Holeshot Video |

I feel measurements need to be taken of the Pylon and the port for the shaft, they both should be centered between the stingers if they are not then your stringer job has major issues. If it is centered and you truely don't have adjustment left, which seem really odd, What ever side is too long, I would just cut the end off of the rod section that slides in and out at the tranny vs. milling the face of the bracket, much easier to do with hack saw then a mill which most don't have acess too anyway and you won't be weaking the bracket either.
he keeps talking about an offset and there isn't one other than the rudder port is slightly offset, but the pylon and strut and packing gland port are all inline with the center line of the boat and all will be centered between the stringers only exception is the rudder port correct? ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

In my experience you would have to do both, the rod being trivial the bracket being less so. It could be different with different generation brackets and transmissions but all the the ones I have the bracket bottoms out on the big end of the rod before the end of the rod interfears with the transmission. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1477 - 1983 Ski Nautique 2001 1967 Mustang 302 "Decoy" http://www.youtube.com/watch?v=cO5MkcBXBBs - Holeshot Video |

| I only had a chance to see the motor/trans hanging in lift. I thought it would be a mount modification to gain a little room (not sure how much needed to achieve, but thought couldn't be much?). The trans mounts were not an option for him and all wood replaced measurements within 1/4", so relocating stringers not an option for me (carpeted and detailed). I decided to cut angle at cradle so mount would bolt directly to inside of stringers (gained 1/4-3/8" on each side). The battle was on !! |

| On a different note. I just happened on to the forum (Thanks to Goggle) researching this "2001". I read several post and thought found to be interesting and informative. Most seem to take alot of pride in their boats (except-the one with spider cracks and major bottom growth. Clean first, then pics and ask if warranty possible?). I'm registered on 3 other forums (bass / fishing boats) and when time permits, try to give a little advice to the "do it yourselfers" and sometimes just read their stories. Probably 80 % of business is fishing boat related- wood replacement to metalflake repairs. We have performed warranty repairs for over 20 different brands (back when there was many !). I certainly look forward to following up with some here as well. Thanks Steve |
