speaking of tig welding, I had a clambake today and decided to heat the pot so it would retain heat in the garage (no water in it)...I rented the pot and yeah, fk i burnt a hole right through it, it was aluminum and it looks like about 150.00 pot...I'll find out tommorow when I tell the guy Im buying his pot. I guess I'll take this one and tig a round patch in it. expensive day.

Thanks for the ideas fellas. I think if you built it up from three layers of 1/2" board you wouldn't have to worry about weak spots because they'd be staggered, just like the Coosa stringers. I think this built-up ply idea might be worth exploring... I like the glue-lam idea as well. But I really wish there were an affordable wood-free option. I'm going to do a lot of experimenting over the next 12 months or so. |

Pete, thanks for the Jamestown suggestion, they are $20 cheaper than West on that evercoat. And for how to set up the links.
As far as the boat goes, I know you like to keep it traditional, but I'm with F & F, my boat has already been completely customized for wakeboarding. I am not worried about re-sale, if I ever sale it, if someone doesn't want to give me what I ask for or like the way I have customized it, then to bad. That's why I want to use the best possible material for the stringers, my boys may inherit the boat in 18 years. Now, I know Overtons isn't the preferred site for ordering materials, but has anyone ever used the Overtons (or any other brand) non-slip coating. I know evercoat makes a good product, but I don't like the fact that you have to mix gel-coat for the color. Two more suggestions for stringers: 1) I have heard of doing fiberglass stringers, making a mold of the stringer in the boat, then pouring the epoxy mixed with glass into the mold. Anyone have experience with that? 2) Boise Cascade has a manufacturing facility ~ 30 min. from my house that produce engineered wood beams. I may go talk to them, let them know what it will be used for and see what they say. |

Not true. The last wood wing I took apart had laminated spars with scarf joints. Not any weaker. Tim |

What Pete didn't emphasize was that plywood typically doesn't come in 14 foot lengths, so there would be a weak spot where you have to overlap the layers. Plus plywood is pretty famous for delaminating when it gets wet. |

Shawn, Due to the problem of finding decent Doug Fir in some parts of the country, we have discussed other options. One of them is the use of LVL (Microlam). Certainly a decent product and it being load rated you sure wouldn't need to worry about the large voids typically found in common plywoods. A plus is it comes already laminated and in any length you need!! It's my #1 choice. before getting into the higher costs/lamination requirements of a composite. |

Why couldn't you laminate plywood for the stringers?
I've been looking at all options in anticipation of my stringer replacement next winter. I'm favoring Coosa board and no foam at this point, but couldn't you save a ton over that by using plywood instead and laminating/building it up like JoeinNY did with the Coosa? |

Pete,I was not aware you could tig brass.Ill give it a try next time.
The problem with the cypress is the same problem I had with the douglas.There is no old growth left and what they call firsts is more like thirds.I didn't understand what old growth was until I crawled under my house(circa 1930)and noticed the wood was smooth as a babies bum.The oak floors are equally impressive. I ended up settling for the best I could find but it was not half as good as the rotted stuff I pulled out of the boat. |

Brad,
I suggest you stay out of the West and the Overtons catalogs. West is high priced and Overtons sells more tubes than boat building supplies!! Here's Jamestown distributors I also recommend you stick with some traditional and more original finishing methods. It will pay in the long run if the time comes you want to sell the boat. You don't want the boat to look like someone over on Wakeworld used truck bed liner on the floor!!! Cypress isn't a bad choice if you can find some nice old growth. It will be fairly dense so it's close to the strength of the Fir. Now the only problem with it is it can be on the oily side which inhibits the resin adhesion. If you do use it, you definately must pre prime/seal with CPES. The CPES has so much solvent in it initially that it will penetrate the oily wood. Actually, any wood you use you will want to CPES!! Linking on CCfan is a little different than other sites. You go to the "post reply", click on the world icon, type in the description, click ok, then in the next box paste the copied address and click ok. |

Ryan,
Next time you have any copper alloys to weld up, try your TIG welder. (looks like your shop is well equiped so I assume you have one). Grab a piece of non fluxed brazing rod, set the Tig to AC and continuous high frequency. It welds like aluminum. |

Here's the link for the carpet:
http://www.snapincarpet.com/ And this is the stuff I'll probably use for the floor since you can get it in various colors: http://www.overtons.com/modperl/product/details.cgi?i=73213&pdesc=Overtons_Rubberized_Nonskid_Marine_Coating_gallon&cname=Non-Skid-Coating&aID=601E3&merchID=1009&r=view |

This has been a good thread, I am planning to do my stringers next winter and have a few questions. Being that I live in Louisiana, I have easy access to cypress wood, would it work as well as Douglas Fir?
Also, the Coosa stuff, just how expensive is it? And if I were to go with Coosa, do you call and order the sizes you need? Can the Coosa be used for the stringers or just for the floor? Suggestion: when I do mine I am going to roll on some of this stuff http://www.westmarine.com/webapp/wcs/stores/servlet/producte/10001/-1/10001/43103/377%20710%201005/0/Primers,%20Undercoats%20/Primary%20Search/mode%20matchallpartial/0/0?N=377 710 1005&Ne=0&Ntt=Primers, Undercoats &Ntx=mode matchallpartial&page=CategoryDisplayLevel1&isLTokenURL=true&storeNum=44&subdeptNum=10892&classNum=10892 Then I plan on having some snap-in carpet made. I had seen a link on here at one time to a company that makes custom carpet for boats. |

That is a 89 with a chevy 350 that my loan officer bought new.He's been looking a ski nautiques for years but never traded out.Maybe now that I have one it will be motivation he needs to upgrade.

Was stuck waiting for gell coat supplies so I figured I would start sorting out some of the accesories.
Had one skeg with a chunk missing so I tried to braise it.I suck at braising for the record. Then I broke the windsheild down and media blasted the frame along with the underwater gear. |

F&F, I guess your primary or main use will be wakeboarding right?
A 16 pitch prop develops around 3000-3100rpms at boarding speeds on most modern V-drive boats Now your engine is stock vs a modern 320-340hp new engine but your boat is quite smaller too. These engines develop it's best pulling power between 2700-3400rpm. I think you'll be in that range with the 16. The 14.25 is the power prop for the newer boats, It will boost your rpms up and give you the best pulling power but I think it would be overkill in such a little boat. |

Without going back through the posts , what are you plans for the engine? Stock? What rpms are you planing on running? The 14.25 pitch shows 35mph at 4600 rpm The 16 pitch shows 39mph at 4600, both using a guestimated slip of 17.5% |

Theres only one way to figure it out and thats the hard way.I still don't understand why acme would recomend a 14.25 pitch prop.Wouldn't that put my topend about thirty five?

I have a brand new 13x17 3 blade OJ that I will never use so once you get in the water if you want to test it let me know.
I also think in the end a set of trim tabs will cure any handling problems you may get at higher speeds from all that weight in the stern. great work |

I am running the acme 13.5 x 16 prop on my 2001. It is larger in diameter than the stock "14x16" federal. It is probably not a bad prop for this boat with 240 hp and the gear reduction,although it's likely to be a 41 mph boat. It has enough clearance. I also have in my possesion a custom 13 x 17 4 blade oj that might be worth a shot depending on how the acme runs. But it is all but guaranteed to twist a stock strength shaft.

Ever wonder why all V-drive boats leave factory with a 4 blade?
Also, are the shaft and strut the same for all the 2001 year range? Or did CC change something for the 89' with the tranny change? Have you considered using a 1,25'' shaft to increase your propeller choices? What prop rotation will you end up using? You can build a hell of a boat, but if you dont get it right with the prop it will run like crap. |

Ryan,
Sounds like you're back to the problem Joe (JoeinNY) brought up early in the thread. Props not large enough for the reduction combined with the 1" bore limit. |

No amount of stern lift is going to help a v-drive.Its the nature of the beast and they all act the same.Porpose,bow rise,hard to plane are just things you learn to deal with.It will be interesting however to see how good this little eighteen footer does compared to some of the monsters I have owned in the past.

4 blade 13.5x16 is a very good prop for that little boat
You could use the added stern lift of the 4 blade with that rear engine setup. |

Problem is the biggest prop acme makes in a one inch shaft is 13.5. I don't know if that will be big enough for the 1.46-1 v-drive.Seems like he recommended a very agressive prop at 13.5-14.25-.60.
Anyways,thanks for the help guys. |

Maybe not. A larger diameter prop if it isn't so close to the hull to cause cavitation should have some gains. Here's why: As pitch is increased, the slip increases and efficiency decreases. If you can run a larger diameter with less pitch then the theoretical slip will be less. |

Chris but the 89 was running the 1.23 transmission correct? I don't know that Ryan will gain anything spinning the larger prop with the 1:1...it may actually hurt the performance? (guessing) ***Edit...I'm retarded...forgetting the whole topic of this thread (V-DRIVE)......(smacks self on forehead) |
