Hull Taper

Just curious about the science behind figuring what taper to bend the sheets of a riveted hull at (stern to bow taper). You look at some of the old Thurmans and they have a lot of taper making the bow deeper. But the later Thurmans, and the newer Benny Webb’s have less taper. The Don Davis’ and Ward...

Re: I'm Building 2 Stossel Boats with High Torque Motors

I agree Rich. But if you talk to some guys, they make it sound like a .125 hull weighs exponentially more. I analyze and research before I do almost anything. I figured the difference to be around 40 pounds. Unless you’re building a pure race boat, .125 is the way to go IMO. I know it says “hull wei...

Re: I'm Building 2 Stossel Boats with High Torque Motors

No brainer on going 7075. I’m no hull builder, but I’ve wondered why more people aren’t building their 7075 hulls out of .125. I did some research two years ago before I ordered my new hull, compared weight figures from multiple suppliers, and figured that a 13x7’2 hull made of .125 only weighs abou...

Re: gotta rebuild

I can tell you why that happens initially Seven3, we can call that Phase#1 and nearly every time it is because of the persons budget! Almost every time boaters take the cheaper route to "just get started" You are totally on point that many people don't really know what they want or more importantly...

Re: gotta rebuild

I know nothing about the Caddy engines, so I’ll stay out of that part of the conversation. But I feel the need to offer some advice with regards to the overall direction you want to go with the boat. IMO, think about what boat you ultimately want to end up with...whether it is DD, gearbox, Water Thu...

Re: The Game Changer

Although I haven’t ridden on one yet, I’ve seen them run. I think they are a comparable alternative to the 540. I don’t think they’re going to outperform a strong 540 (at this point), and I don’t foresee them taking a big chunk of the market away from the 540, but for the guy who hates going to the ...

Re: I'm Building 2 Stossel Boats with High Torque Motors

Those welded boats look like that very quickly if you run any dry. I’ve seen a welded aluminum boat that was only 6 months old that looked just like your buddies hull. You get what you pay for.

Re: The Game Changer

So Davie GSO480, I’ve seen the pics of boats you have owned in the past. You and I have very similar tastes in boats (riveted aircraft hulls with 540 power). For your ‘next’ boat, would you stay this DD route, go LS w/gearbox, or go back to aircraft? Good question man...depends what you want out of...

Re: The Game Changer

I agree Sniper, this is a good thing. More options are always better, especially when you’re talking about cheaper options in a very expensive hobby. One thing that is causing me doubt is that prop. That’s not a lot of prop. I have a buddy who runs a 5 blade Alpha on his 540, I believe it’s a 70”, b...

Re: The Game Changer

So is that one of the key elements to making a DD work, making the blades shorter so that you can spin it past 3K RPM? I always thought 3K RPM was the limit.

Always things that can be improved, our "sport" needs the constant progress or it will fade eventually I agree, but I disagree. No doubt, this platform will have its place.

Re: Gear Box or Not

I have owned probably a dozen 305 powered Monte Carlos and El Camino’s from the 80s...you are looking at 150 to 160 hp tops. My advice is to keep that boat as is so that it doesn’t become a money pit. You could put a box on it and it still might not even run dry. Might be better off putting that mon...

This feud you guys are having is both hilarious and entertaining, lol. But it seems like it’s all in good fun. I know this is more of a HP vs TQ debate than a CM vs AC, but in the end that’s what it ends up being. IMO it all comes down to the size of the boat you need to power. 12 foot and under, ge...

CMB I am going to speculate that the direct drive project has been abandoned and you are now going the 7,000 rpm route. On the DD topic, I heard that there is someone (unknown) who has been working on a set of heads for an LS direct drive. Supposedly they are using an epoxy to narrow up and reshape...

Re: I'm Building 2 Stossel Boats with High Torque Motors

I just went out to the shop and pulled my dipstick. I last changed my oil on January 17. A conservative estimate is that I have probably 12-15 hours on this oil, I’ve run the boat 6 or 7 times this year so far. Some quick rides, a couple of long rides, so it’s probably more than 12-15 hours. I run A...

I changed my oil and filter every 25 hrs - what is your schedule?? I go on the 25 hour schedule too, but I have only owned this boat/motor for 3 years, no telling about the previous 27 years.

Did you have low oil pressure with the pan in that condition? Also, would your oil turn dark quickly after an oil change?

Hell, your “basic” riveted glades boat with a nice 540 is going to cost you around 40k these days. That’s built brand new from scratch with all good quality parts. Not including getting crazy with paint, light bars, etc. Sure, you can do it a little cheaper if you build your own rigging, or buy a us...
