Ok, I may be taking too simplistic a view of this but let me see if I understand the question.......Let's assume that a surfacing , rotating prop will tend to push the rear of the boat to the left. The moment upon which this force is exerted is the very back of the strut, and anything forward of...

Here is a boat using that idea. I don't think it's done and tested yet, but it should be pretty interesting: http://p086.ezboard.com/fjimsrcboatdockfrm...icID=3865.topic . At this point, the sponsons don't steer, but they are adjustable, and suspended. B)

One of my favorite sayings is "There are 2 sides to every story.......and the truth is generally somewhere in the middle." Differing opinions can exist in the same thread, as long as people don't feel the need to try to discredit anyone with a opinion differing from theirs. With tolerance of the...

Going back to your first post on this thread Tom..... I couldn't agree more. The best cure for this is a little moderator editing and/or deleting posts. It doesn't take too long for folks to realize what can and will be tolarated and what will not. I participate heavily on another boating forum...

Good idea. This would be an excellent mechanism for building a permanant knowledge base. B)

Well, here's another vote for a read only FAQ with an edited version of the bearing maintenance thread, pinned for all to learn from. Jim's (JRCBD) has a section like that, and you can spend weeks trying to absorb all the great info contained there. Some other good candidates would be the 100+...

What better proof do ya need? :D

What happens is the rough surface keeps the layer of air molecules closest to it tumbling, and any raw fuel that gets near the walls gets caught up in this turbulent layer and is atomized. I use 80 or 60 grit stones or sandpaper rolls on car and boat intakes and crankcase or heads, whichever...

I'm no small engine guru, but I've done a lot of porting in my years as an automotive technician, mostly on hot street andrace cars, and a few fullsize outboards. My opinion is that cranks and rotating stuff needs to be flowed and polished and stationary intake surfaces should be slightly rough...

I'm not a nitro or small motor guru by any means, but it seems that there must be some heat involved to get a good final fit. After all, there will be heat when it's running, which will change both piston and bore dimensions. Just my 2 cents worth(maybe only 1.5 due to inflation, :rolleyes: )...

Hey 1BS, how's it going Jim? :D

Nitrous can make most any motor think it's twice the size it really is. ;)

Hey , 50 ain't old .................................................................................... .....if yer a tree, :lol: :lol: :lol: B)

Kewl, I started messing around again here right at New Years. Dragged my ole Dumas Scarab out and figured out what it is, and put a gas Homie motor in it. Bought a used and abused SprintCat hull at the WinterNats for my next project. Not sure what motor I'm going to do in that one yet. I've got...

Hey 1Bad Is dat you Jim? S&F 1Bad?

I've been told that a Zen W/C manifold and/or won't fit the Homie motor. Why is that? Different bolt spacing? Different pipe size? Right now I'm running a steel manifold/header I whipped up at the shop along with the chamber from my K&B 11cc, but it's melting the silicone connector, and I really...

Thanks for that info Tom. It's nice to get a perspective from folks that have been there. I might buy a "builder" motor eventually, but for now, I want to try my own hand at seeing how much power I can extract on my own, (and learning to use it, ;) ) I just don't want to be trying to turn a...

That part kinda goes without saying, ;) . I found that this Homie has a 4 port cylinder, with what looks like a 2 port case, so I did considerable matching. I opened and smoothed the bottom of the transfer ports, and then opened the transfer slots in the case to match. Is there any gain to...

TOO LATE!!!! I've already tried my hand at some port work. My Homie went under the knife last Sunday and Monday night. I didn't cut the cylinder base (no mill handy), but I did replace the paper base gasket with some GelSeal II anerobic sealer. I didn't get too radical yet, but it really sounds...
