| Hey y'all, I've got a 78' ski nautique that originally came with a ladder but has been removed and holes "filled".... I've purchased an original teak platform with brackets ($150 for anyone wondering) and I'd like to mount it to my boat but I have no holes to guide where it should mount. I'm hoping someone can give me some simple measurements as to where I should mount it and if anyone has any tips on drilling holes or hardware type to use or sealants to apply that would also be very much appreciated!! |

You can put tape on the gel coat before drilling to keep it from chipping. Start with small drill & go up in size in steps. Do you have OEM brackets? I would think they pretty much dictate position. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

Yeah I have oem brackets and platform but how high is it seated from the bottom is what I'm looking for, I don't want it so high you can get on it or so low it drags. I figured there's a sweet spot someone might could give me a measurement on. |

| It appears the diaries section may be better as a for sale section. I thumbed through a few pages and couldnt find much on rebuilding, mostly just selling. |

After you drill the holes for the brackets counter sink the gelcoat so it does not develop stress cracks. You want the holes to resemble this- \ / more than this- I I ------------- 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 |

| Thanks for the advise, do you recommend any certain type of bit for this application or just anything and go slow? |

For through-bolting the platform, I would use 3M marine sealants: 5200 (permanent) or 4200 (removable) JQ ------------- Current 2003 Ski Nautique 206 Limited Previous 2001 Ski Nautique Open Bow 1994 Ski Nautique Open Bow Aqua skiing, ergo sum |

If it were mine : I would make up some nut plates instead of just using nuts and washers. Maybe 1/4 X 2 X 2 aluminum plates. You could even make them long enough to capture both holes in one piece. Thru drill these and use lock nuts and washers also. These will spread out the load and help from cracking. Just one of many methods. ------------- Keep it as original as YOU want it 1978 Mustang (modified) |

Just go slow using a small bit to drill a pilot hole. Measure twice drill once  ------------- 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 |

| Would you use sealant in the holes themselves or on the inside of plates...or both? |

Smear it everywhere. 4200 so it is easier to remove ------------- Keep it as original as YOU want it 1978 Mustang (modified) |

| Cool I think I got it....put boat in the water....mark where I want it to sit....drill small holes while stepping it up slowly....round over gelcoat edges to prevent cracking....use a mounting plate on inside to disperse weight evenly and use 4200 marine sealant everywhere......I think I'll have this thing on tomorrow then...just in time for the weekend fun!! |
